整合Struts2.2+Spring3.0
2014-08-08
学习李刚老师的j2ee整合struts2+spring3
JAR包链接
http://download.csdn.net/detail/u010393809/7732235
项目outline
1.引入JAR包,上面已经贴了JAR包下载链接
2.配置Struts2,只需要引入struts2必需的那几个包,此时暂时不要引入struts2-spring-plugin-2.2.1.jar,不然会抛出javaPointerNull的异常
配置web.xml;
配置struts.xml
<struts>
<constant name="struts.configuration.xml.reload" value="http://www.mamicode.com/true"/>
<package name="admin" namespace="/admin" extends="struts-default" >
<action name="hello">
<result>/index.jsp</result>
</action>
</package>
</struts>
地址栏输入http://localhost:8080/SSH/admin/hello可以访问index.jsp,可知Struts2的包没有问题,能完成正常功能
下面开始整合Struts2+Spring3
1.将剩下的JAR包全部引入

5.org.crazyit.app.service.MyService.java
package org.crazyit.app.service;public interface MyService { boolean valid(String username , String pass);}

7.struts.xml
<?xml version="1.0" encoding="GBK"?><!-- 指定Struts 2配置文件的DTD信息 --><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN" "http://struts.apache.org/dtds/struts-2.1.7.dtd"><!-- Struts 2配置文件的根元素 --><struts> <!-- 配置了系列常量 --> <constant name="struts.i18n.encoding" value="http://www.mamicode.com/GBK"/> <constant name="struts.devMode" value="http://www.mamicode.com/true"/> <package name="lee" extends="struts-default"> <!-- 定义处理用户请求的Action,该Action的class属性不是实际处理类 , 而是Spring容器中的Bean实例--> <action name="loginPro" class="loginAction"> <!-- 为两个逻辑视图配置视图页面 --> <result name="error">/content/error.jsp</result> <result name="success">/content/welcome.jsp</result> </action> <!-- 让用户直接访问该应用时列出所有视图页面 --> <action name="*"> <result>/content/{1}.jsp</result> </action> </package></struts>
8.applicationContext.xml

输入http://localhost:8080/SSH/login,进入登录页面
根据逻辑判断,将跳转到/welcome.jsp或者/error.jsp
