整合SSH开发：先让spring整合hibernate，而后在整合Struts
第一步：
思路：显拷入spring所需要的jar包，而后在拷入hibernate所需要的包，最后导入Struts所需要的包
用myeclipse整合开发的步骤：
1.新建一个web项目 右击添加spring支持，我选择使用的spring2.5支持
2.添加hibernate支持
附：
然后到项目src路径下找到applicationContext.xml文件打开，

<!-- 声明采用注解方式管理事务 -->

</property>

<!-- 配置action整合Struts -->
<bean name="/user2" class="com.yourcompany.struts.action.User2Action"></bean>
</beans>
详解：
applicationContext.xml就是整个整合的核心文件，它集成了hibernate.cfg.xml,Struts Action,所以此文件非常重要，几乎所有的配置都在此文件内完成
在myeclipse的数据库模式下，反向生成对应数据库表的映射类及映射文件
生成Struts的action类，要想在action类中调用服务层DAO，可以通过spring的依赖注入，注入一个DAO服务层，
对应的Struts-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" "http://struts.apache.org/dtds/struts-config_1_3.dtd">
<struts-config>
<form-beans >
<form-bean name="user2Form" type="com.yourcompany.struts.form.User2Form" />
</form-beans>
<global-exceptions />
<global-forwards />
<action-mappings >
<action
attribute="user2Form"
input="/form/user2.jsp"
name="user2Form"
path="/user2"
scope="request"
type="com.yourcompany.struts.action.User2Action">
<forward name="success" path="/index.jsp" />
</action>
</action-mappings>
<!-- 配置spring控制器把创建action的工作交给spring来完成，接下来在spring中配置action -->
<controller
processorClass="org.springframework.web.struts.DelegatingRequestProcessor">
</controller>
<message-resources parameter="com.yourcompany.struts.ApplicationResources" />
</struts-config>
在action内调用dao
采用注解的方式@Resource MyuserDAO dao;注入dao服务层
然后就可以直接调用服务层地方法进行操作了
最后在web.xml文件中添加spring配置文件，让服务开启的时候自动加载，同时配置上一个spring实力化工厂，让spring自动实例化，并存储在application范围内
