MyEclipse搭建 Struts1/Spring2/Hibernate3 集成开发环境 -

MyEclipse搭建 Struts1/Spring2/Hibernate3 集成开发环境

本例用MyEclipse6.0 + Eclipse3.3 + MySQL5.1

创建Web Project ：

创建Package（包）目录结构：

项目右键 MyEclipse 导入Struts1.3 （Strtus1.3.10 是 Apache 在 2008年12月14日停止更新前的最后版本）

项目右键 MyEclipse 导入Spring2

cmd 启动数据库服务

打开MyEclipse DataBase Explorer

新建数据库连接，加入数据库驱动Jar包，选择Finish。

导入Hibernate3.1

把Hibernate.cfg.xml 对数据库的管理交给 Spring , 选择 Spring configuration file (applicationContext.xml)

因为将SessionFactory Bean交给 Spring 管理，所以不需要创建此工具类，勾选去掉。

点击Finish完成，此时文档结构如下图：

ApplicationContext.xml 文件内容：

切换到 MyEclipse DataBase Explorer ，在 DB Brower 中选择实体表反转出实体对象。

点击Finish 。

Web.xml 添加如下代码：

1 <?xml version="1.0" encoding="UTF-8"?>
2 <web-app xmlns="http://java.sun.com/xml/ns/javaee"
3          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4          version="2.5"

将ApplicationContext.xml 拆分为四份，并新建各层接口与实现类：

1 package com.ssh.dao;
2
3 public interface IBaseDao {
4
5 }

1 package com.ssh.dao;
2
3 public interface IUserDao extends IBaseDao {
4
5 }

1 package com.ssh.dao.impl;
2
3 import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
4 import com.ssh.dao.IBaseDao;
5
6 public class BaseDaoHibernateImpl extends HibernateDaoSupport implements IBaseDao {
7
8 }

1 package com.ssh.dao.impl;
2
3 import com.ssh.dao.IUserDao;
4
5 public class UserDaoHibernateImpl extends BaseDaoHibernateImpl implements IUserDao {
6
7 }

1 package com.ssh.service;
2
3 public interface IUserService {
4
5 }

1 package com.ssh.service.impl;
2
3 import com.ssh.dao.IUserDao;
4 import com.ssh.service.IUserService;
5
6 public class UserServiceImpl implements IUserService {
7     private IUserDao userDaoImpl ;
8
9     public IUserDao getUserDaoImpl() {
10         return userDaoImpl;
11     }
12
13     public void setUserDaoImpl(IUserDao userDaoImpl) {
14         this.userDaoImpl = userDaoImpl;
15     }
16 }

1 package com.ssh.web.action;
2
3 import org.apache.struts.actions.DispatchAction;
4
5 public class BaseAction extends DispatchAction {
6
7 }

1 package com.ssh.web.action;
2
3 import javax.servlet.http.HttpServletRequest;
4 import javax.servlet.http.HttpServletResponse;
5
6 import org.apache.struts.action.ActionForm;
7 import org.apache.struts.action.ActionForward;
8 import org.apache.struts.action.ActionMapping;
9
10 import com.ssh.service.IUserService;
11
12 public class SearchAction extends BaseAction {
13     private IUserService userServiceImpl ;
14
15     public IUserService getUserServiceImpl() {
16         return userServiceImpl;
17     }
18
19     public void setUserServiceImpl(IUserService userServiceImpl) {
20         this.userServiceImpl = userServiceImpl;
21     }
22
23     public ActionForward search(ActionMapping mapping, ActionForm form,
24             HttpServletRequest request, HttpServletResponse response)
25             throws Exception {
26
27         return super.execute(mapping, form, request, response);
28     }
29
30 }

1 package com.ssh.web.action.form;
2
3 import org.apache.struts.action.ActionForm;
4
5 public class SearchActionForm extends ActionForm {
6
7 }

四份配置文件之一：applicationContext-common.xml
配置数据源、接管SessionFactory Bean、将事务横切到 service层 , 设置事务规则。

44         <property name="sessionFactory">
45             <ref bean="sessionFactory" />
46         </property>
47     </bean>
48
49     <tx:advice id="txAdvice" transaction-manager="transactionManager">
50         <tx:attributes>
51             <tx:method name="append*" propagation="REQUIRED"/>
52             <tx:method name="remove*" propagation="REQUIRED"/>
53             <tx:method name="modify*" propagation="REQUIRED"/>
54             <tx:method name="*" read-only="true"/>

56     </tx:advice>
57
58     <aop:config>
59         <aop:pointcut id="all" expression="execution(* com.ssh.service.impl.*.*(..))"/>
60         <aop:advisor advice-ref="txAdvice" pointcut-ref="all"/>
61     </aop:config>
62 </beans>

四份配置文件之二：applicationContext-dao.xml
将sessionFactort注入Dao层 , 因为

UserDaoHibernateImpl extends BaseDaoHibernateImpl

BaseDaoHibernateImpl extends org.springframework.orm.hibernate3.support.HibernateDaoSupport

所以Dao层不需要写 sessionFactory的get/set访问器

四份配置文件之三：applicationContext-service.xml

Service 层需提供 userDaoImpl 的get/set访问器

四份配置文件之四：applicationContext-action.xml

action 类需提供 userServiceImpl get/set访问器
注意：此处 <bean name="/search" ...>
/search 为 Strtus-config.xml 中配置的 action 请求路径

Strtus-config.xml 文件
整合Struts1 和 Spring 的关键在type中不写自己的Action类路径
采用Spring提供的代理类：org.springframework.web.struts.DelegatingActionProxy
注意：path="/search" 需要与 applicationContext-action.xml 中<bean name="/search" ...> 对应

1 <?xml version="1.0" encoding="UTF-8"?>
2 <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">
3
4 <struts-config>
5   <data-sources />
6   <form-beans >
7     <form-bean name="searchActionForm" type="com.ssh.web.form.SearchActionForm" />
8   </form-beans>
9   <global-exceptions />
10   <global-forwards />
11   <action-mappings >
12     <action
13       input="/index.jsp"
14       name="searchActionForm"
15       parameter="method"
16       path="/search"
17       scope="request"
18       type="org.springframework.web.struts.DelegatingActionProxy">
19           <forward name="success" path="/index.jsp"></forward>
20      </action>
21   </action-mappings>
22   <message-resources parameter="com.ssh.web.ApplicationResources" />
23 </struts-config>

到此，Struts1.3 Spring2.5 Hibernate3.1 整合完成。
