<bean id="dataSource"
  class="org.apache.commons.dbcp.BasicDataSource">
  <property name="driverClassName"
   value="com.mysql.jdbc.Driver">
  </property>
  <property name="url"
   value="jdbc:mysql://localhost:3306/mysql">
  </property>
  <property name="username" value="root"></property>
  <property name="password" value="root"></property>
 </bean>

如果改为C3P0则为：

<bean id="propertyConfigurer"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location">
            <value>classpath:jdbc.properties</value>
        </property>
    </bean>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver" />
        <property name="jdbcUrl" value="${jdbc.url}" />
        <property name="user" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="autoCommitOnClose" value="true"/>
        <property name="checkoutTimeout" value="${cpool.checkoutTimeout}"/>
        <property name="initialPoolSize" value="${cpool.minPoolSize}"/>
        <property name="minPoolSize" value="${cpool.minPoolSize}"/>
        <property name="maxPoolSize" value="${cpool.maxPoolSize}"/>
        <property name="maxIdleTime" value="${cpool.maxIdleTime}"/>
        <property name="acquireIncrement" value="${cpool.acquireIncrement}"/>
        <property name="maxIdleTimeExcessConnections" value="${cpool.maxIdleTimeExcessConnections}"/>
    </bean>
jdbc.properties：

# Database URL
jdbc.url=jdbc:mysql://192.168.0.25"3306/db

# Database login information
jdbc.username=root
jdbc.password=

# Time to wait for an open connection before timing out
# (in milliseconds)
cpool.checkoutTimeout=5000

# Connection pool size
cpool.minPoolSize=5
cpool.maxPoolSize=40

# How long to keep unused connections around(in seconds)
# Note: MySQL times out idle connections after 8 hours(28,800 seconds)
# so ensure this value is below MySQL idle timeout
cpool.maxIdleTime=25200

# How long to hang on to excess unused connections after traffic spike
# (in seconds)
cpool.maxIdleTimeExcessConnections=1800

# Acquiring new connections is slow, so eagerly retrieve extra connections
# when current pool size is reached
cpool.acquireIncrement=5

或者将上面的3部分写成一个：
<bean id="c3p0DataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
      <property name="driverClass">
        <value>${jdbc.driverClassName}</value>
      </property>
      <property name="jdbcUrl">
        <value>${jdbc.url}</value>
      </property>
      <property name="user">
       <value>${jdbc.username}</value>
      </property>
      <property name="password">
       <value>${jdbc.password}</value>
      </property>
      <property name="initialPoolSize"><value>10</value></property>
      <property name="minPoolSize"><value>5</value></property>
      <property name="maxPoolSize"><value>30</value></property>
      <property name="acquireIncrement"><value>5</value></property>
      <property name="maxIdleTime"><value>10</value></property>
      <property name="maxStatements"><value>0</value></property>
    </bean>

如果使用的是受管理的J2EE服务器，则在spring中配置为JNDI连接：
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>java:comp/env/jndi/xxx</value>
</property>
</bean>

如果在应用里有独自使用hibernate，则在spring中配置hibernate连接池，使用C3P0如下：
<bean   id="DataSource"  
  class="org.apache.commons.dbcp.BasicDataSource">  
  <property   name="driverClassName">  
  <value>oracle.jdbc.driver.OracleDriver</value>  
  </property>  
  <property   name="url">  
  <value>jdbc:oracle:thin:@172.16.20.241:1521:dbsvr</value>  
  </property>  
  <property   name="username">  
  <value>hl3000</value>  
  </property>  
  <property   name="password">  
  <value>hldw3101</value>  
  </property>  
  </bean>  
  <bean   id="SessionFactory"  
  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">  
  <property   name="dataSource">  
  <ref   bean="DataSource"   />  
  </property>  
  <property   name="hibernateProperties">  
  <props>  
  <prop   key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>  
  <prop   key="hibernate.show_sql">true</prop>  
   
  <!--   C3P0连接池配置   -->  
  <prop   key="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</prop>  
  <prop   key="hibernate.c3p0.max_size">20</prop>  
  <prop   key="hibernate.c3p0.min_size">5</prop>  
  <prop   key="hibernate.c3p0.timeout">120</prop>  
  <prop   key="hibernate.c3p0.max_statements">100</prop>  
  <prop   key="hibernate.c3p0.idle_test_period">120</prop>  
  <prop   key="hibernate.c3p0.acquire_increment">2</prop>  
  <prop   key="myeclipse.connection.profile">hl3000</prop>  
  </props>  
  </property>  
  <property   name="mappingResources">  
  <list>  
  <value>com/hl3000/DBLogic/POJO/PermUserAccount.hbm.xml</value>  
  </list>  
  </property>  
  </bean> 

spring中配置独立使用hibernate时使用jndi的配置：

hibernate.dialect = net.sf.hibernate.dialect.MySQLDialect
hibernate.connection.datasource=java:comp/env/jdbc/SAMPLEDB
hibernate.show_sql=true

如果是使用不受管理的Servlet容器如Tomcat，也可以使用jndi的方式配置，需要在tomcat中配置数据源，在server.xml中增改大致如下：

     <Resource name="jdbc/testDb" auth="Container"
                    type="javax.sql.DataSource"/>
          <ResourceParams name="jdbc/testDB">\\数据源的名称
            <parameter><name>username</name><value>root</value></parameter>数据库的名称
            <parameter><name>password</name><value>password</value></parameter>数据库密码
            <parameter><name>driverClassName</name>
              <value>org.gjt.mm.mysql.Driver</value></parameter>\\要加载的驱动
            <parameter><name>url</name>
              <value>jdbc:mysql://172.20.0.73/rk?</value></parameter>\\要连接的URL
          </ResourceParams>

    /index.jsp=ROLE_ADMIN,ROLE_TECHNICIAN
    /order/createOrder.jsp=ROLE_TECHNICIAN
    /order/authorizeOrder.jsp=ROLE_ADMIN
    /login.jsp=ROLE_ANONYMOUS,ROLE_TECHNICIAN,ROLE_ADMIN

login.jsp的form：

<form action="<c:url value='j_acegi_security_check'/>" method="POST">
<table width=50% border=0 align="center">
 <tr>
  <td>User:</td>
  <td><input type='text' name='j_username'
   </td>
 </tr>
 <tr>
  <td>Password:</td>
  <td><input type='password' name='j_password'></td>
 </tr>

 <tr>
  <td colspan='2'><input name="submit" type="submit">&nbsp;
  <input name="reset" type="reset" value="Clear"></td>
 </tr>
</table>
</div>
</div>
</form>


使用相应的用户名登录后即可有相应的权限，否则重新转到登录页面。

相关jar：

acegi-security-1.0.5.jar - Main classes of the Acegi Security system
cglib-2.1.3.jar - Code-generation library used by Spring
commons-codec-1.3.jar - Encoders and decoders such as Base64, Hex, Phonetic, and URLs
commons-lang-2.1.jar - Helper utilities for java.lang APIs
ehcache-1.2.3.jar - Used for basic caching purposes
freemarker-2.3.8.jar - Used by the Struts implementation
jstl.jar, standard.jar - JavaServer Pages Standard Tag Library (JSTL) tag library
log4j-1.2.13.jar - For logging
ognl-2.6.11.jar - OGNL library used by the Struts implementation
sitemesh-2.3.jar - SiteMesh JAR
spring.jar - Spring Framework JAR
struts2-core-2.0.8.jar - Struts 2 core JAR
xwork-2.0.3.jar - Used by Struts

修改web.xml：

作用是利用spring AOP将filter Proxy到web.xml里去，并拦截相关的request

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
  version="2.4">
  <display-name>AcegiTraining</display-name>
  <context-param>

    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext*.xml</param-value>
  </context-param>
  <filter>
    <filter-name>Acegi Filter Chain Proxy</filter-name>

    <filter-class>
      org.acegisecurity.util.FilterToBeanProxy
    </filter-class>
    <init-param>
      <param-name>targetClass</param-name>
      <param-value>

        org.acegisecurity.util.FilterChainProxy
      </param-value>
    </init-param>
  </filter>
  ...
  ...
  <filter-mapping>
    <filter-name>Acegi Filter Chain Proxy</filter-name>

    <url-pattern>/j_acegi_security_check</url-pattern>
  </filter-mapping>
  <filter-mapping>
    <filter-name>Acegi Filter Chain Proxy</filter-name>
    <url-pattern>/j_acegi_logout</url-pattern>

  </filter-mapping>
  <filter-mapping>
    <filter-name>Acegi Filter Chain Proxy</filter-name>
    <url-pattern>*.action</url-pattern>
  </filter-mapping>

  <filter-mapping>
    <filter-name>Acegi Filter Chain Proxy</filter-name>
    <url-pattern>*.jsp</url-pattern>
  </filter-mapping>
  ...

</web-app>


二、身份验证

WEB-INF下增加applicationContext-acegi-security.xml文件，并增加验证服务所需要的filter：

web.xml中的FilterToBeanProxy将拦截的内容：

<bean id="filterChainProxy"
    class="org.acegisecurity.util.FilterChainProxy">

    <property name="filterInvocationDefinitionSource">
      <value>
        CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
        PATTERN_TYPE_APACHE_ANT
        /j_acegi_security_check*=httpSessionContextIntegrationFilter,authenticationProcessingFilter
        /**/*=httpSessionContextIntegrationFilter,logoutFilter,
authenticationProcessingFilter,securityContextHolderAwareRequestFilter,
anonymousProcessingFilter,exceptionTranslationFilter,filterInvocationInterceptor
      </value>
    </property>

  </bean>

如果未经过允许的请求，将会由exceptionTranslationFilter处理，将页面转到注册页面处去处理，authenticationProcessingFilterEntryPoint，是身份验证的入口：

                       
<bean id="exceptionTranslationFilter"
  class="org.acegisecurity.ui.ExceptionTranslationFilter">
  <property name="authenticationEntryPoint">
    <ref local="authenticationProcessingFilterEntryPoint" />
  </property>

  ...
</bean>

<bean id="authenticationProcessingFilterEntryPoint"
  class="org.acegisecurity.ui.webapp.AuthenticationProcessingFilterEntryPoint">
  <property name="loginFormUrl">
    <value>/login.jsp</value>
  </property>

  <property name="forceHttps">
    <value>false</value>
</bean>


authenticationProcessingFilter就是进行身份验证所用到的的filter，其主要是依靠authenticationManager来进行数据库或文本文件上存放的注册信息来进行核对：

<bean id="authenticationProcessingFilter"
  class="org.acegisecurity.ui.webapp.AuthenticationProcessingFilter">
  <property name="authenticationManager">
    <ref bean="authenticationManager" />
  </property>

  <property name="authenticationFailureUrl">
    <value>/login.jsp?login_error=1</value>
  </property>
  <property name="defaultTargetUrl">
    <value>/</value>

  </property>
  <property name="filterProcessesUrl">
     <value>/j_acegi_security_check</value>
  </property>
</bean>


<bean id="authenticationManager"
  class="org.acegisecurity.providers.ProviderManager">
  <property name="providers">

    <list>
      <ref local="daoAuthenticationProvider" />
      <ref local="anonymousAuthenticationProvider" />
    </list>
  </property>
</bean>


<bean id="daoAuthenticationProvider"
    class="org.acegisecurity.providers.dao.DaoAuthenticationProvider">
    <property name="userDetailsService"/><ref local="userDetailsService"/></property>
    <property name="userCache">

    ...
    </property>
  </bean>
 
  <bean id="userDetailsService"
    class="org.acegisecurity.userdetails.memory.InMemoryDaoImpl">
    <property name="userProperties">
      <bean
        class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="location"
          value="/WEB-INF/users.properties" />

      </bean>
    </property>
  </bean>


users.properties：
james=tom@1231,ROLE_TECHNICIAN
krishna=krish2341,ROLE_TECHNICIAN
smith=pravah@001,ROLE_ADMIN

三、权限验证

在身份验证后，通过权限验证来决定哪些资源由拥有哪些权限的用户使用，httpRequestAccessDecisionManager控制投票方式，exceptionTranslationFilter增加了如果权限验证失败后所转到的处理页面，logoutFilter定义登出后转到首页:

<bean id="filterInvocationInterceptor"
  class="org.acegisecurity.intercept.web.FilterSecurityInterceptor">
  <property name="authenticationManager">
    <ref bean="authenticationManager" />
  </property>
  <property name="accessDecisionManager">

    <ref local="httpRequestAccessDecisionManager" />
  </property>
  <property name="objectDefinitionSource">
    <value>
      PATTERN_TYPE_APACHE_ANT
    /index.jsp=ROLE_ADMIN,ROLE_TECHNICIAN
    /order/createOrder.jsp=ROLE_TECHNICIAN
    /order/authorizeOrder.jsp=ROLE_ADMIN
    /login.jsp=ROLE_ANONYMOUS,ROLE_TECHNICIAN,ROLE_ADMIN
    </value>
  </property>

</bean>

<bean id="exceptionTranslationFilter"
    class="org.acegisecurity.ui.ExceptionTranslationFilter">
    <property name="authenticationEntryPoint">
      <ref local="authenticationProcessingFilterEntryPoint" />
    </property>

    <property name="accessDeniedHandler">
      <bean
        class="org.acegisecurity.ui.AccessDeniedHandlerImpl">
        <property name="errorPage" value="/accessDenied.jsp" />
      </bean>
    </property>
  </bean>


<bean id="httpRequestAccessDecisionManager"
    class="org.acegisecurity.vote.AffirmativeBased">
    <property name="allowIfAllAbstainDecisions">
      <value>false</value>

    </property>
    <property name="decisionVoters">
      <list>
        <ref bean="roleVoter" />
      </list>
    </property>

  </bean>
  <bean id="roleVoter" class="org.acegisecurity.vote.RoleVoter" />

<bean id="logoutFilter"
  class="org.acegisecurity.ui.logout.LogoutFilter">
  <constructor-arg value="/index.jsp" />
  <!-- URL redirected to after logout -->
  <constructor-arg>

    <list>
      <bean
        class="org.acegisecurity.ui.logout.SecurityContextLogoutHandler" />
    </list>
  </constructor-arg>
</bean>


至此，acegi配置部分完成，剩下相关页面设计部分。

去下载了FCKeditor_2.5.1.zip和FCKeditor-2.3.zip，一个是JAVA版本的文件，一个是FCK原本的文件。摆放的方式大概如下图：


web.xml加入代码：

 <!-- fckeditor -->

  <servlet>

        <servlet-name>Connector</servlet-name>
        <servlet-class>com.fredck.FCKeditor.connector.ConnectorServlet</servlet-class>

        </init-param>

        <init-param>

            <param-value></param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>  

  <servlet-mapping>
    <servlet-name>Connector</servlet-name>
    <url-pattern>/FCKeditor/editor/filemanager/browser/default/connectors/jsp/connector</url-pattern>
  </servlet-mapping>

  <servlet-mapping>
    <servlet-name>SimpleUploader</servlet-name>
    <url-pattern>/FCKeditor/editor/filemanager/upload/simpleuploader</url-pattern>
  </servlet-mapping>

输入的jsp文件类似如下：

  <html:form action="/fck" method="post">
    <fck:editor id = "fcktext" basePath = "/new1/FCKeditor/"
    height = "100%"
    skinPath = "/new1/FCKeditor/editor/skins/default/"
    toolbarSet = "Default"
        imageBrowserURL = "/new1/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector"
        linkBrowserURL = "/new1/FCKeditor/editor/filemanager/browser/default/browser.html?Connector=connectors/jsp/connector"
        flashBrowserURL = "/new1/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Flash&Connector=connectors/jsp/connector"
    imageUploadURL = "/new1/FCKeditor/editor/filemanager/upload/simpleuploader?Type=Image"
       linkUploadURL = "/new1/FCKeditor/editor/filemanager/upload/simpleuploader?Type=File"
       flashUploadURL = "/new1/FCKeditor/editor/filemanager/upload/simpleuploader?Type=Flash" >
    </fck:editor>
    <html:submit/><html:cancel/>
    </html:form>

其中的id是对应于ActionForm与validationv.xml里的property。分别类似如下：

  String strfcktext = fckForm.getString("fcktext");

<form name="fckForm">
        <field property="fcktext" depends="required">
       <arg key="fckForm.fcktext"/>    
       </field>  
   </form>

另外需要注意的是，如果显示找不到页面的错误，应该是form里FCK相关的路径设置不正确。数据库段的字段也需要设置足够大。如果传输过程里出现乱码，可以所有jsp页面加入：<%@ page language="java" contentType="text/html; charset=UTF-8"%>，在web.xml里加入u-f8 filter：

<!-- u-f8 filter -->
  <filter>
  <filter-name>encodingFilter</filter-name>
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  <init-param>
   <param-name>encoding</param-name>
   <param-value>UTF-8</param-value>
  </init-param>
 </filter>

 <filter-mapping>
  <filter-name>encodingFilter</filter-name>
  <url-pattern>*.do</url-pattern>
 </filter-mapping>

 <filter-mapping>
  <filter-name>encodingFilter</filter-name>
  <url-pattern>*.jsp</url-pattern>

]]>自己写了一个ssh分页http://www.blogjava.net/lzj520/archive/2008/01/10/174373.htmllzj520lzj520Thu, 10 Jan 2008 10:55:00 GMThttp://www.blogjava.net/lzj520/archive/2008/01/10/174373.htmlhttp://www.blogjava.net/lzj520/comments/174373.htmlhttp://www.blogjava.net/lzj520/archive/2008/01/10/174373.html#Feedback2http://www.blogjava.net/lzj520/comments/commentRss/174373.htmlhttp://www.blogjava.net/lzj520/services/trackbacks/174373.html
首先，先创建一个显示每一页（有若干条数据）的方法（如下面的hfindAll方法），决定好每一页接收一个页码参数，然后显示该页码里的数据。比如有100条数据，那么分10页，那第几页显示第几条至第几条数据。然后再创建一个方法是用于在view层显示页数（如下面的amountPage方法），最后是在view层上为每一页数的数字加上超链接。

以下是主要代码：
public class LoginDAO extends HibernateDaoSupport {
private int PageSize =5;
/*设置每页的数据条数*/

 public Integer amountPage(){
     Session session =this.getSession();
  Query query = session.createQuery("from Login");
  query.setCacheable(true);
  int a = query.list().size()%PageSize;
/*总记录数/每页数据数,判断是否能整除*/
  Integer amount;
  if(a!=0){
   amount = query.list().size()/PageSize+1;
/*如果整除有余数，则页数加1*/
  }else{
   amount = query.list().size()/PageSize;
/*如果整除没余数，则直接总记录数/每页数据数*/
  }
  return amount;
 }

 public List hfindAll(String pagenum) {
     Session session =this.getSession();
  Query query = session.createQuery("from Login");
  if (pagenum == null){
/*如果pagenum是空，则数据从第一条开始*/
  query.setFirstResult(0);
/*设置查询开始的第几条数据，这里是从第1条开始*/
  query.setMaxResults(PageSize);
/*设置查询数据条数，这里是5条*/
  query.setCacheable(true);
/*设置一级缓存*/
  }else{
   Integer p = (Integer.valueOf(pagenum)-1) * PageSize;
   query.setFirstResult(p);
   query.setMaxResults(PageSize);
   query.setCacheable(true);
  }
  return query.list();
 }
}

然后需要解决的是一些数据传递，类型转换和在view层显示的问题，主要代码如下：

在ACTION里：
String strpagenum = request.getParameter("pagenum");
  List results= loginManage.hfind(strpagenum);
  Integer amountPage = loginManage.amountPage();
    if(results!=null){
             HttpSession session=request.getSession();
             session.setAttribute("results",results);
             session.setAttribute("amountPage",amountPage);
             return mapping.findForward("ok");
         }
    return mapping.findForward("fail");

在view视图里：
显示每页数据的代码：

 <logic:iterate id="element" name="results">    <tr>
   <td width="100"><input type="checkbox" name="select" value="<bean:write name="element" property="id"/>"><bean:write name="element" property="id"/></td>
   <td width="100"><bean:write name="element" property="name"/> </td>
   <td width="100"><bean:write name="element" property="password"/></td>
   </tr></logic:iterate>

显示页码的代码：
<%
   int i;
  int a=Integer.parseInt(session.getAttribute("amountPage").toString());
   for (i=1;i<=a;i++){
   out.println("<tr>");  
          out.println("<td><a href='display.do?pagenum="+ i +"'>"+ i +"</a></td>");    
          out.println("</tr>");    
   }
    %>

]]>spring+hibernate里session的管理http://www.blogjava.net/lzj520/archive/2008/01/10/174392.htmllzj520lzj520Thu, 10 Jan 2008 10:41:00 GMThttp://www.blogjava.net/lzj520/archive/2008/01/10/174392.htmlhttp://www.blogjava.net/lzj520/comments/174392.htmlhttp://www.blogjava.net/lzj520/archive/2008/01/10/174392.html#Feedback0http://www.blogjava.net/lzj520/comments/commentRss/174392.htmlhttp://www.blogjava.net/lzj520/services/trackbacks/174392.html 或者是[org.hibernate.jdbc.ConnectionManager] - <finalizing with closed connection>
那是因为有可能是你自己手动创建了session，比如：

private static final SessionFactory sessionFactory;

    static {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            sessionFactory = new Configuration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }
然后调用：

Session session = sessionFactory.openSession();
Query query = session.createQuery("from Login");

类似这样的单独使用hibernate时的用法，是需要手工去关闭session的。没有关闭的话就会收到那样的警告。

所以最好是使用spring管理的session，和OpenSessionInViewFilter，比如：
Session session =this.getSession();
然后在web.xml里加入
  <filter>
  <filter-name>OpenSessionInViewFilter</filter-name>
  <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
  </filter>
  <filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

其中在spring里注册的sessionfactory必须是id="sessionFactory"，如果是id="SessionFactory"或者其他，会提示sessionFactory没有注册的错误，因为OpenSessionInViewFilter里注册的名必须为sessionFactory。

就是acegi保护并认识这3类的url，但是再次发出页面请求的时候，tomcat没有报错。不过页面一直在读取进度，没有显示，郁闷喇

 public void delete(Integer lid) {
        log.debug("deleting Login instance");
        try {
         Login login=(Login)this.getHibernateTemplate().load(Login.class,lid);
            getHibernateTemplate().delete(login);

调用DAO：
Integer selid = Integer.valueOf(request.getParameter("select"));
loginDAO.delete(selid);

批量删除
需要注意的是in后面跟的是字符串，如果不是会提示org.hibernate.QueryException: unexpected char: ';'的出错
DAO代码：
public void delete(String[] lid) {
    String[] ids = lid;
         String str="";
         for(int i=0;i<ids.length;i++){
             str+="'"+ids[i]+"'";
             if(i!=(ids.length-1))
                 str+=",";
             }
  List list   =   this.getHibernateTemplate().find("from Login where id in ("+str+")");
  if(list.size()>0){  
     this.getHibernateTemplate().deleteAll(list);
     }
 }

调用DAO：
String[] lid = request.getParameterValues("select");
loginDAO.delete(lid);

Spring2.0 Hibernate3.1.x/Hibernate3.2

在使用Spring的AOP编程时，会用到这几个lib：
asm-2.2.2.jar
asm-commons-2.2.2.jar
asm-util-2.2.2.jar

Hibernate如果使用lib：
asm.jar
asm-attrs.jar

其中asm-2.2.2.jar与asm.jar存在类上的冲突！！！
使用其中之一或两者都使用，可能会出现如下错误：
java.lang.NoClassDefFoundError: org/objectweb/asm/CodeVisitor
java.lang.NoClassDefFoundError: org/objectweb/asm/commons/EmptyVisitor
java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit。。。。。。

解决办法是：
1）.去掉类路径上的关于Hibernate的3个lib
asm.jar
asm-attrs.jar
cglib-2.1.3.jar
2）.加入Spring中的以下4个lib
asm-2.2.2.jar
asm-commons-2.2.2.jar
asm-util-2.2.2.jar
cglib-nodep-2.1_3.jar

如果再不行，都试试删删看。


java.lang.SecurityException: class "javax.xml.bind.JAXBContext"'s signer information does not match signer information of other classes in the same package
这个错误是因为载入的包里面有两个相同路径的类，就是在一个包里面有两个同名的类
有可能是将相同的包载入两次或者把包解开后，先将jar文件载入了，后又将解开的类载入了


Error configuring application listener of class org.springframework.web.context.ContextLoaderListener
试试自己去下一个spring的包，把包里的spring.jar加到项目里去。eclipse生成的时候可能会有些包没有放进去。


Error creating bean with name 'datasource' defined in file
Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool
试试将commons-dbcp.jar，commons-pool.jar和commons- collections.jar加入CLASSPATH中


hibernate 3.1 中的hibernateTemplate ，class应该为org.springframework.orm.hibernate3.HibernateTemplate，而非org.springframework.orm.hibernate.HibernateTemplate，因为某些原因我现在还用3.1，早前在玩springside的时候感觉hibernate 3.2 的Hibernate Annotations方便多了。

找不到action或报错的另一少有原因，一些版本hibernate版本会有些冲突方面的问题，可换一版本的hibernate试试，个人感觉hibernate的版本对应用会比较敏感


org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in resource [/WEB-INF/dataAccessContext-hibernate.xml] of ServletContext: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/transaction/TransactionManager
java.lang.NoClassDefFoundError: javax/transaction/TransactionManager

原因：缺少jta.jar 或者是找不到hbm.xml文件导致sessionfactory出错,检查hbm文件路径是否正确,文件是否存在
<property name="mappingResources">
  <list>
  <value>com/yourcompany/model/Login.hbm.xml
  </value>
  </list>
  </property>


2007-06-26 18:38:13,671 ERROR [com.yourcompany.model.dao.LoginDAO] - <save failed>
org.springframework.jdbc.BadSqlGrammarException: Hibernate operation: could not insert: [com.yourcompany.model.Login]; bad SQL grammar [insert into mysql__login (name, password) values (?, ?)]; nested exception is java.sql.SQLException: Table 'mysql.mysql__login' doesn't exist
java.sql.SQLException: Table 'mysql.mysql__login' doesn't exist

把hbm文件里面的catalog="'mysql"去掉即可！
另注意的一点是eclipse生成的DAO文件应该是：
    public void save(Login transientInstance) {
        log.debug("saving Login instance");
        try {
            getHibernateTemplate().save(transientInstance);
            log.debug("save successful");
        } catch (RuntimeException re) {
            log.error("save failed", re);
            throw re;
        }
    }
而不是原来的    public void save(LoginDAO transientInstance)

只要在applicationContext.xml中加上
<property name="mappingResources">
<list>
<value>com/yourcompany/hibernate/Users.hbm.xml</value>
</list>
</property>
加这段代码就会找不到action
换一个版本的hibernate应该就ok


Invalid path /addcustomer was requested
输入的路径不正确，检查spring中注册的action的路径和输入的路径是否一致，留意大小写是否一致

        <param-name>contextConfigLocation</param-name> 
        <param-value>classpath*:spring/*.xml</param-value>
    </context-param>  
这样将web层和service层的配置分开摆放，看起来比较清晰。具体可参考springside的example

另一方法是struts-config中直接写 <plug-in  className="org.springframework.web.struts.ContextLoaderPlugIn"> 
<set-property property="contextConfigLocation"  value="classpath*:spring/*.xml"/> 
</plug-in>
这样将所有的配置文件直接放在spring目录下

或小型应用可简单写成最直接的<plug-in className= "org.springframework.web.struts.ContextLoaderPlugIn"> <set-property property= "contextConfigLocation" value="/WEB-INF/applicationContext.xml"/>


不过多句提醒下记得不要漏了web.xml中还应有    <listener> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
 </listener> 

struts-config.xml中还应有：
 <controller>
  <set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor"/>
 </controller>

说明你的log4j.properties没有配置。请把log4j.properties放到工程的classpath中，eclipse的classpath为bin目录，由于编译后src目录下的文件会拷贝到bin目录下，所以你可以把log4j.properties放到src目录下。
这里给出一个log4j.properties的例子：

log4j.rootLogger=DEBUG,stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %5p (%F:%L) - %m%n


在spring中如何配置的log4j
在web.xml中加入以下代码即可。
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/log4j.properties</param-value>
</context-param>
