MyEclipse6.0 整合 Spring2.0 , Strust2 ,Hibernate3.0

MyEclipse6.0 整合 Spring2.0 , Strust2 ,Hibernate3.0

（1） 添加struts2支持

1.导入jar包
freemarker.jar,ognl.jar,struts2-core.jar,xwork.jar,需要注意的是,struts2-core.jar和struts2-all.jar不能共存。

2.添加struts.xml

1. <?xml version="1.0" encoding="UTF-8" ?>
2. <!DOCTYPE struts PUBLIC
3.      "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
4.      "http://struts.apache.org/dtds/struts-2.0.dtd">
5.  
6. <struts>
7.      <!-- 是否为Struts的开发模式 -->
8.      <constant name="struts.devMode" value="true" />
9.      <!-- action的后缀 -->
10.      <constant name="struts.action.extension" value="do" />
11.      <!-- 是否重新加载国际化属性文件 -->
12.      <constant name="struts.i18n.reload" value="true" />
13.      <!-- 是否为Struts的开发模式 -->
14.      <constant name="struts.objectFactory" value="spring" />
15.      <!-- 是否重新加载xml配置 -->
16.      <constant name="struts.configuration.xml.reload" value="true"/>
17.      <!-- 是否允许动态方法调用 -->
18.      <constant name="struts.enable.DynamicMethodInvocation" value="true" />
19.  
20.      <package name="action" extends="struts-default">
21.          <action name="TestAction" class="com.lmj.web.action.TestAction">
22.              <result>/service/welcome.jsp</result>
23.          </action>
24.      </package>
25. </struts>

3.修改web.xml

1. <filter>
2.      <filter-name>struts-cleanup</filter-name>
3.      <filter-class>
4.          org.apache.struts2.dispatcher.ActionContextCleanUp
5.      </filter-class>
6. </filter>
7. <filter>
8.      <filter-name>struts2</filter-name>
9.      <filter-class>
10.          org.apache.struts2.dispatcher.FilterDispatcher
11.      </filter-class>
12. </filter>
13.  
14. <filter-mapping>
15.      <filter-name>struts-cleanup</filter-name>
16.      <url-pattern>/*</url-pattern>
17. </filter-mapping>
18. <filter-mapping>
19.      <filter-name>struts2</filter-name>
20.      <url-pattern>/*</url-pattern>
21. </filter-mapping>

（2） 添加hibernate支持

1.先在MyEclipse Derby测试数据库连接成功后,然后添加hibernate支持。再切换到MyEclipse Database Explorer, 找到需要的表,右键选择Hibernate Reverse Engineering...,导入实体类以及与表相关联的xml即可。
如果手写，到网上找些Hibernate.cfg.xml,表关联的xml的配置更改一下,再导入jar包就行了。

（3） 添加spring支持

1.MyEclipse添加spring支持时，勾选常用的Spring 2.0 AOP,Spring 2.0 Core,Spring 2.0 Web

创建applicationContext.xml

1. <?xml version="1.0" encoding="UTF-8"?>
2.      <beans xmlns="http://www.springframework.org/schema/beans"
3.      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4.      xmlns:aop="http://www.springframework.org/schema/aop"
5.      xmlns:tx="http://www.springframework.org/schema/tx"
6.      xsi:schemaLocation="http://www.springframework.org/schema/beans
7.      http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
8.      http://www.springframework.org/schema/tx
9.      http://www.springframework.org/schema/tx/spring-tx-2.0.xsd
10.      http://www.springframework.org/schema/aop
11.      http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">
12.  
13.      <!-- 数据源 -->
14.      <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
15.          <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
16.          <property name="url" value="jdbc:mysql://localhost:3306/mysql?characterEncoding=gb2312">
17.          </property>
18.          <property name="username" value="root"></property>
19.          <property name="password" value="sa"></property>
20.      </bean>
21.  
22.      <!-- session工厂 -->
23.      <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
24.          <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
25.      </bean>
26.  
27.      <!-- daos -->
28.      <bean id="tempDAO" class="com.lmj.web.dao.impl.TempDAO">
29.          <property name="sessionFactory" ref="sessionFactory"></property>
30.      </bean>
31.  
32.      <!-- actions -->
33.      <bean id="TestAction" class="com.lmj.web.action.TestAction">
34.          <property name="tempDAO" ref="tempDAO"></property>
35.      </bean>
36.  
37.      <!-- 配置TransactionManager -->
38.      <bean id="myTxManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
39.          <property name="sessionFactory" ref="sessionFactory" />
40.      </bean>
41.  
42.      <!-- 配置事务策略 -->
43.      <tx:advice id="txAdvice" transaction-manager="myTxManager">
44.          <tx:attributes>
45.              <tx:method name="find*" propagation="REQUIRED" read-only="true"/>
46.              <tx:method name="save*" propagation="REQUIRED"/>
47.              <tx:method name="update*" propagation="REQUIRED"/>
48.              <tx:method name="delete*" propagation="REQUIRED"/>
49.              <tx:method name="*" propagation="SUPPORTS" read-only="true" />
50.          </tx:attributes>
51.      </tx:advice>
52.  
53.      <aop:config>
54.          <aop:pointcut id="productServiceMethods" expression="execution(* service.*.*(..))" />
55.          <aop:advisor advice-ref="txAdvice" pointcut-ref="productServiceMethods" />
56.      </aop:config>
57. </beans>

（4） 整合spring,hibernate

1.修改数据源

a.采用spring的数据源,首先添加类库Spring 2.0 ORM/DAO/Hibernate3.0
数据提供类: org.springframework.jdbc.datasource.DriverManagerDataSource

1. <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource ">
2.      <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
3.      <property name="url" value="jdbc:mysql://localhost:3306/mysql?characterEncoding=gb2312">
4.      </property>
5.      <property name="username" value="root"></property>
6.      <property name="password" value="sa"></property>
7. </bean>

b.apache数据池,所需jar包,commons-dbcp.jar,commons-pool.jar与commons-collections.jar
数据提供类: org.apache.commons.dbcp.BasicDataSource

1. <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
2.      <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
3.      <property name="url" value="jdbc:mysql://localhost:3306/mysql?characterEncoding=gb2312">
4.      </property>
5.      <property name="username" value="root"></property>
6.      <property name="password" value="sa"></property>
7. </bean>

c.JNDI数据池
数据提供类: org.springframework.jndi.JndiObjectFactoryBean

1. <bean id="dataSource" class="org.springframework.indi.JndiObjectFactoryBean"> 
2.      <property name="jndiName">
3.          <value>jdbc/TestDB</value> 
4.      </property>      
5. </bean>

（5） 整合spring,struts2

1.导入struts2-spring-plugin.jar,struts2目录下可以找到

2.struts.xml 进行常量配置,交给spring管理

1. <struts/>
2.      <constant name="struts.objectFactory" value="spring" />
3. <struts/>

3.web.xml 把监听权交给spring

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

4.applicationContext.xml 里创建action对象

1. <bean id="TestAction" class="com.lmj.web.action.TestAction">
2.      <property name="tempDAO" ref="tempDAO"></property>
3. </bean>

5.struts.xml 里创建action对象,name必须与applicationContext.xml里bean的id一致

1. <action name="TestAction" class="com.lmj.web.action.TestAction">
2.      <result>/service/welcome.jsp</result>
3. </action>
