tsh Tapestry Spring Hibernate 集成笔记 (转)

原文:http://blog.yesky.com/236/javafoot/1209236.shtml

参考了网上好多文章,记不太清了,在此一并感谢!主要有:
Tapestry整合Spring实践 http://tech.blogbus.com/logs/2004/06/219144.html

1、在eclipse中新建tapestry项目,项目名称tshDemo
2、菜单myEclipse-->Add Spring Capabilities... ,


点击Next> ,注意的一点是,没有使用myeclipse自带的jar包,而是选择User Libraries自己定义的最新的spring开发包(方法是在Window-->Preferences...-->Java-->Build Path-->User Libraries中定义),为了使WEB-INF/lib目录下包含相应jar包,选择拷贝到目录


点击Finish,完成对spring支持,有一个不好的是,eclipse会把所有的jar包文件一个个明细的列在项目名下,倍长非常不方便,修改办法,在项目属性-->Java Build Path-->Libraries中,把所有的明细jar包全部选中删除,点击Add Library...-->User Library-->Next> -->勾选相应的user library-->Finish 即可

3、修改web.xml如下:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app
      PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
      "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
  <display-name>tshDemo</display-name>

  <filter>
    <filter-name>redirect</filter-name>
    <filter-class>org.apache.tapestry.RedirectFilter</filter-class>
    <init-param>
      <param-name>redirect-path</param-name>
      <param-value>/app</param-value>
    </init-param>
  </filter>

  <filter-mapping>
    <filter-name>redirect</filter-name>
    <url-pattern>/</url-pattern>
  </filter-mapping>

  <listener>
    <listener-class>
      org.springframework.web.context.ContextLoaderListener
    </listener-class>
  </listener>

  <servlet>
    <servlet-name>tshDemo</servlet-name>
    <servlet-class>
      org.apache.tapestry.ApplicationServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>tshDemo</servlet-name>
    <url-pattern>/app</url-pattern>
  </servlet-mapping>
</web-app>

4、修改applicationContext.xml如下:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
  <description>Spring Quick Start</description>
  <bean id="theAction" class="tsh.demo.service.LowerAction">
    <property name="message">
      <value>HeLLo </value>
    </property>
  </bean>

</beans>

5、新建3个包,tsh.demo.dao 持久层,tsh.demo.service 中间层,tsh.demo.web 表示层

6、tapestry支持spring,新建tapestry engine类,如下:
/*
 * package tsh.demo.web;
 * class tsh.demo.web.EngineWithSpring
 * Created on 2006-1-23, 17:49:43
 */
package tsh.demo.web;

import java.util.Map;

import org.apache.tapestry.engine.BaseEngine;
import org.apache.tapestry.request.RequestContext;
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

public class EngineWithSpring extends BaseEngine {

 private static final long serialVersionUID = 1L;
 public static final String APPLICATION_CONTEXT_KEY = "appContext";
 
 protected void setupForRequest(RequestContext context) {
  super.setupForRequest(context);
  Map global = (Map) getGlobal();
  ApplicationContext ac = (ApplicationContext) global.get(APPLICATION_CONTEXT_KEY);
  if (ac == null) {
   ac = WebApplicationContextUtils.getWebApplicationContext(context.getServlet().getServletContext());
  }
  System.out.println("测试" + ac);//你可以看看这一句在什么时候执行,从而了解Engine是什么时候被调用的;
  global.put(APPLICATION_CONTEXT_KEY, ac);
 }
}

7、修改tapestry配置文件tshDemo.application,如下:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE application PUBLIC
  "-//Apache Software Foundation//Tapestry Specification 3.0//EN"
  "http://jakarta.apache.org/tapestry/dtd/Tapestry_3_0.dtd">
<!-- generated by Spindle, http://spindle.sourceforge.net -->

<application name="tshDemo" engine-class="tsh.demo.web.EngineWithSpring">
   
    <description>add a description</description>
   
    <page name="Home" specification-path="Home.page"/>
   
</application>

8、修改Home.page文件,如下:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE page-specification PUBLIC
  "-//Apache Software Foundation//Tapestry Specification 3.0//EN"
  "http://jakarta.apache.org/tapestry/dtd/Tapestry_3_0.dtd">
<!-- generated by Spindle, http://spindle.sourceforge.net -->

<page-specification class="tsh.demo.web.pages.Home">

    <description>add a description</description>
    <property-specification name="theAction" type="tsh.demo.service.Action" >
     global.appContext.getBean("theAction")
    </property-specification>
    <property-specification name="greeting" type="java.lang.String" />
   
</page-specification>

9、Home类,如下:
/*
 * package tsh.demo.web.pages;
 * class tsh.demo.web.pages.Home
 * Created on 2006-1-24, 10:51:12
 */
package tsh.demo.web.pages;

import org.apache.tapestry.event.PageEvent;
import org.apache.tapestry.event.PageRenderListener;
import org.apache.tapestry.html.BasePage;

import tsh.demo.service.Action;

public abstract class Home extends BasePage implements PageRenderListener {

 public abstract Action getTheAction();
 public abstract void setGreeting(String greeting);
 
 /* (non-Javadoc)
  * @see org.apache.tapestry.event.PageRenderListener#pageBeginRender(org.apache.tapestry.event.PageEvent)
  */
 public void pageBeginRender(PageEvent event) {
  System.out.println(getTheAction().execute("Rod Johnson"));
  setGreeting(getTheAction().execute("Rod Johnson"));
 }
}

10、Home.html文件,如下:
<html jwcid="@Shell" title="application">
<head></head>
<body>
   <h3>welcome, </h3><h1><span jwcid="@Insert" value="ognl:greeting" /></h1>
</body>
</html>

11、相关spring bean 类如下:
/*
 * package tsh.demo.service;
 * class tsh.demo.service.Action
 * Created on 2005-11-23, 16:32:52
 */
package tsh.demo.service;

public interface Action {
 public String execute(String str);
}

/*
 * package tsh.demo.service;
 * class tsh.demo.service.LowerAction
 * Created on 2005-11-23, 16:36:32
 */
package tsh.demo.service;

public class LowerAction implements Action {
  private String message;
  
  public String getMessage() {
  return message;
  }
 
  public void setMessage(String string) {
   message = string;
  }
 
  public String execute(String str) {
    return (getMessage() + str).toLowerCase();
 }

}

/*
 * package tsh.demo.service;
 * class tsh.demo.service.UpperAction
 * Created on 2005-11-23, 16:34:17
 */
package tsh.demo.service;

public class UpperAction implements Action {

  private String message;
  
  public String getMessage() {
  return message;
  }
 
  public void setMessage(String string) {
   message = string;
  }
 
  public String execute(String str) {
   return (getMessage() + str).toUpperCase();
  }

}

12、在%CATALINA_HOME%\conf\Catalina\localhost目录下建tshDemo.xml文件,如下:
<Context path="/tshDemo" docBase="D:\eclipseWorks\workspace\tshDemo\context"
        debug="0" privileged="true" reloadable="true">
  <Logger className="org.apache.catalina.logger.FileLogger"
             prefix="localhost_Mssql_log." suffix=".txt"
             timestamp="true"/>

    <!-- maxActive: Maximum number of dB connections in pool. Make sure you
         configure your mysqld max_connections large enough to handle
         all of your db connections. Set to 0 for no limit.
         -->

    <!-- maxIdle: Maximum number of idle dB connections to retain in pool.
         Set to -1 for no limit.  See also the DBCP documentation on this
         and the minEvictableIdleTimeMillis configuration parameter.
         -->

    <!-- maxWait: Maximum time to wait for a dB connection to become available
         in ms, in this example 10 seconds. An Exception is thrown if
         this timeout is exceeded.  Set to -1 to wait indefinitely.
         -->

    <!-- username and password: MySQL dB username and password for dB connections  -->

    <!-- driverClassName: Class name for the old mm.mysql JDBC driver is
         org.gjt.mm.mysql.Driver - we recommend using Connector/J though.
         Class name for the official MySQL Connector/J driver is com.mysql.jdbc.Driver.
         -->
   
    <!-- url: The JDBC connection url for connecting to your MySQL dB.
         The autoReconnect=true argument to the url makes sure that the
         mm.mysql JDBC Driver will automatically reconnect if mysqld closed the
         connection.  mysqld by default closes idle connections after 8 hours.
         -->
  <!--Resource name="jdbc/m2Base" auth="Container" type="javax.sql.DataSource"
    maxActive="100" maxIdle="30" maxWait="10000"
    url="jdbc:jtds:sqlserver://im04:1433;DatabaseName=m2Base"
    username="xxxx" password="xxxxxxxxx" driverClassName="net.sourceforge.jtds.jdbc.Driver"
    removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true" />

  <Resource name="jdbc/merp" auth="Container" type="javax.sql.DataSource"
    maxActive="100" maxIdle="30" maxWait="10000"
    url="jdbc:jtds:sqlserver://im04:1433;DatabaseName=merp"
    username="xxxxxxx" password="xxxxxxxxx" driverClassName="net.sourceforge.jtds.jdbc.Driver"
    removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true" /-->

</Context>


/**
 * Hibernate的集成日后补充
 **/
66、启动tomcat,访问http://locahost:8080/tshDemo,如果页面正常显示,配置成功。
