         ===============Spring+Hibernate+Struts配置===============
spring加载log4j
   web.xml

   < context - param >
    
< param - name > log4jConfigLocation </ param - name >
    
< param - value >/ WEB - INF / classes / log4j.properties </ param - value >
  
</ context - param >
  
< listener >
    
< listener - class > org.springframework.web.util.Log4jConfigListener </ listener - class >
  
</ listener >


一.spring+struts
1.加载springContext
      通过struts-config.xml中增加plug-in插件来加载springContext
   <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
     <set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml" />
   </plug-in>
  
applicationContext.xml为spring的配置文件

2.将strutsAction交给Spring容器进行管理
      修改struts-config.xml中的action属性,action的type值不指定具体的实现类,统一修改成代理类

  
  <action input="/login.jsp"
         name="loginActionForm"
         path="/loginAction" 
         scope="request"   
         type="org.springframework.web.struts.DelegatingActionProxy"
         validate="false">
      <forward name="success" path="/success.jsp" />
      <forward name="failure" path="/failure.jsp" />
    </action>

3.在applicationContext.xml中的bean name值设定与struts-config.xml中action path值相对应,以使代理类DelegatingActionProxy能够根据传入的path在springContext中找到相应的bean,并将实例返回给struts.
<bean name="/loginAction" class="com.derek.action.LoginAction" singleton="false">
  <property name="login">
    <ref bean="loginBOProxy" />
  </property>
</bean>

二.spring+hibernate
  
1.dateSource
      在springContext中设置dateSource Bean
     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver"></property>
        <property name="url" value="jdbc:jtds:sqlserver://192.168.56.32:1433/testDB"></property>
        <property name="username" value="it"></property>
        <property name="password" value="it"></property>
     </bean>
     2.sessionFactory
       在springContext中设置sessionFactory Bean
  <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <property name="mappingResources">
        <list>
          <value>hbm\OvertimeRecord.hbm.xml</value><!--hbm映射文件-->
          <value>hbm\OvertimePermit.hbm.xml</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
           <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
           <prop key="hibernate.show_sql">true</prop>
           <prop key="hibernate.jdbc.fetch_size">50</prop>
           <prop key="hibernate.jdbc.batch_size">20</prop>
        </props>
    </property>
  </bean>
 
 
3.transactionManager
   在springContext中设置transactionManager Bean
 
  <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
     <property name="sessionFactory">
       <ref local="sessionFactory" />
     </property>
   </bean>

  
4.DAO bean
      <bean id="Ilogin" class="com.derek.business.Login">
          <property name="sessionFactory">
              <ref local="sessionFactory"/>
          </property>
      </bean>
      public class Login extends HibernateDaoSupport implements LoginInterface
      DAO 继承HibernateDaoSupport
      HibernateSupport实现了HibernateTemplate和SessionFactory实例的关联, HibernateTemplate对Hibernate Session操作进行了封装,HibernateTemplate.execute方法则是一封装机制的核心. 借助HibernateTemplate我们可以脱离每次数据操作必须首先获得Session实例、启动事务、提交/回滚事务以及烦杂的try/catch/finally的繁琐操作.
        Spring中的事务管理实际上是基于动态AOP机制实现,为了实现动态AOP,Spring在默认情况下会使用Java DynamicProxy,但是,Dynamic Proxy要求其代理的对象必须实现一个接口,该接口定义了准备进行代理的方法。而对于没有实现任何接口的Java Class,需要采用其他方式,Spring通过CGLib实现这一功能。


   5.DAOProxy 代理bean
        通过代理,将上面的DAO bean 纳入到spring容器的事务管理中,并在其中设置对哪些方法进行事务管理
     <bean id="loginBOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
           <property name="transactionManager">
                <ref bean="transactionManager" />
           </property>
           <property name="target">
                <ref local="Ilogin" /> <!--所代理的bean-->
           </property>
           <property name="transactionAttributes">
                <props>
                     <prop key="insert*">PROPAGATION_REQUIRED</prop> <!--以insert开头的方法加入事务管理-->
                     <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop> <!--以get开头的方法只读-->
                </props>
           </property>
      </bean>

    
    6.action bean
      <bean name="/loginAction" class="com.derek.action.LoginAction" singleton="false">
         <property name="login">
            <ref bean="loginBOProxy" /> <!--要将其使用的DAO bean加入事务管理,就必须ref他的代理bean,且在LoginAction中该属性须由其接口强制类型转换-->
         </property>
      </bean>

LoginInterface
package com.derek.myinterface;

public boolean check(String name,String pwd);
}

Login
package com.derek.business;

import com.derek.myinterface.LoginInterface;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import java.util.List;

public class Login extends HibernateDaoSupport implements LoginInterface{
    
private SessionFactory sessionFactory;
    
private String hsql = "from OvertimePermit where account=? and password=?";
    
public Login() {}
    
public boolean check(String name,String pwd){
        String condition[] 
= {name, pwd};//查询条件
        /**

LoginAction通过容器注入的Login实例完成业务操作(必须由接口强制类型转化)
package com.derek.action;

import javax.servlet.http.*;
import com.derek.form.*;
import org.apache.struts.action.*;
import org.apache.log4j.Logger;
import com.derek.myinterface.LoginInterface;

public class LoginAction extends Action {
    
private LoginInterface login;
    
public ActionForward execute(ActionMapping actionMapping,
                                 ActionForm actionForm,
                                 HttpServletRequest servletRequest,
                                 HttpServletResponse servletResponse) {
        Logger log 
= Logger.getLogger(this.getClass().getName());
        LoginActionForm loginActionForm 
= (LoginActionForm) actionForm;
        String name 
= loginActionForm.getName();
        String pwd 
= loginActionForm.getPwd();
        
boolean TF = login.check(name,pwd);
        
if(TF){ log.warn("LoginSuccess------------");;return actionMapping.findForward("success");}
          
else{ log.warn("LoginFailure------------");;return actionMapping.findForward("failure");}
    }
    
public void setLogin(LoginInterface Ilogin) {this.login = Ilogin;}
    
public LoginInterface getLogin() {return login;}
}

类中直接通过Context获得bean实例(必须通过代理类获得实例且由其接口强制类型转化)

package com.derek.pub;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import com.derek.myinterface.IRecordDao;
import java.util.List;
import hbm.OvertimeRecord;

public class Untitled1 {
    
public Untitled1() {
    ApplicationContext ctx 
= new FileSystemXmlApplicationContext("applicationContext.xml");
    IRecordDao recordDao 
= (IRecordDao)ctx.getBean("RecordDaoProxy");
    OvertimeRecord newor 
= new OvertimeRecord("004104","dada","100120","it","2006/04/02","2006/04/02","001145","david","001145","david","00","00","1","1","1","1");
    newor.setMark(
"0");
    recordDao.insert(newor);
    List l 
= recordDao.findAll("from OvertimeRecord");
    
for(int i=0;i<l.size();i++){
    OvertimeRecord or 
= (OvertimeRecord)l.get(i);
    System.out.println(or.getId());
    }
    }
    
public static void main(String[] a){
    Untitled1 u 
= new Untitled1();
    }
}

      一个Spring application context的定义能够被很多种不同的上下文实现所读取, 比如FileSystemXmlApplicationContextClassPathXmlApplicationContext以及XmlWebApplicationContext。 默认的情况下,一个web应用程序会从”WEB-INF/applicationContext.xml”中得到root context。 在所有的Spring应用中,XML文件中定义的application context会把所有相关的application beans连接起来, 包括Hibernate session factory以及数据访问和业务对象(就像上面定义的那些bean)。 它们中的大部分都不会意识到被Spring容器所管理,甚至在同其他bean合作的时候, 因为它们仅仅遵循JavaBeans的规范。一个bean属性及可以表示值参数,也可以是其他的合作bean。 下面的bean定义能够作为Spring web MVC context的一部分,在最基础的 application context中访问business beans。

ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(servletContext);
ProductService productService 
= (ProductService) context.getBean("myProductService");
ApplicationContext context 
=
    
new FileSystemXmlApplicationContext("C:/myContext.xml");
ProductService productService 
=
    (ProductService) context.getBean(
"myProductService");
ApplicationContext context 
=
    
new ClassPathXmlApplicationContext("myContext.xml");
ProductService productService 
=
    (ProductService) context.getBean(
"myProductService");

package person.action;

import javax.servlet.ServletContext;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionServlet;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import person.PersonService;
public class BaseAction extends Action {


private PersonService personService;

public void setServlet(ActionServlet actionServlet) {

super.setServlet(actionServlet);
ServletContext servletContext = actionServlet.getServletContext();
WebApplicationContext wac = null;
wac=WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
this.personService = (PersonService) wac.getBean("personServiceImp");
}
protected PersonService getPersonService() {
return this.personService;
}

}
当我调试时,在wac=WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext); 处出现异常,我想知道为什么会这样,应该怎样解决,请高手指教,谢谢!  回复  更多评论

你用的是hibernate3.0吧! 但你的spring配置文件中不是
<bean id="sessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean">

应该是:
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
你试试!  回复  更多评论

在spring配置文件中配置一下action 如:
<bean name="/loginAction" class="com.derek.action.LoginAction" singleton="false">
<property name="login">
<ref bean="loginBOProxy" />
</property>
</bean>

和在struts-config配置文件中声明loginAction的
type = "org.springframework.web.struts.DelegatingActionProxy "

那么在action中有set,get方法, spring 会帮你注入你定义的bean,无须你再自己用WebApplicationContextUtils去获得bean实例  回复  更多评论
