SSH2整合

网上的教程很多，参考了一些，自己再总结一下。

版本：Struts2.2.3  Spring3.0 Hibernate3.3

myeclipse8.6

整合步骤如下：

1、新建web工程

2、添加spring

3、添加hibernate

4、添加struts2

5、配置文件

新建web工程

添加spring

添加hibernate

注：之前可以先添加dataSource 具体步骤：Window->Open Perspective->MyEclipse Database Explorer

切换到Database Explorer视图

对表进行Hibernate反向转换

添加struts2

向/WEB-INF/lib添加jar包

最小jar包

配置web.xml

<?xml version="1.0" encoding="UTF-8" ?> 
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  </welcome-file-list>
</web-app>

配置struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!--  指定Struts 2配置文件的DTD信息  -->
<!DOCTYPE struts PUBLIC
      "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

            <result name="input">index.jsp</result>
        </action>

解决的方法：

com.ideal.service.impl.UserServiceImpl实现的是com.ideal.service.interfaces.UserService接口，由于spring实现的是接口注入，关联的实现类。这里实现注入类，所以出现了异常。
在spring配置文件加入以下代码，实现类注入

<aop:config proxy-target-class="true"></aop:config> 

遇到的问题：

org/objectweb/asm/Type异常
nested exception is java.lang.NoClassDefFoundError: 
org/objectweb/asm/Type

解决方法：

原因是Spring中的cglib-nodep-2.x.x.jar与Hibernate中的cglib-2.2.jar相冲突!
两种框架整合时Spring中的cglib-nodep-2.x.x.jar是必须的,取消Hibernate中的cglib-2.2.jar即可
