使用IDEA+Maven搭建整合一个Struts2+Spring4+Hibernate4项目，混合使用传统Xml与@注解，返回JSP视图或JSON数据，快来给你的SSH老项目翻新一下吧

大学时做过一些基于Struts+Spring+Hibernate的项目，但是项目是使用MyEclipse或者Eclipse工具来开发的，而且还是外部地引入依赖包，甚是麻烦。想着翻新一下曾今写的一些SSH项目，于是使用IDEA+Maven来搭建整合一下。主要就是拿来玩的，听说Struts2挺多漏洞的，有过几次漏洞事故，不知修复得怎么样，至于这个技术，大家就简单看看就好了。

一、创建一个Maven项目

（1）项目名称为“j2ee-struts2-spring4-hibernate4”

（2）pom.xml

  4.0.0
  org.example
  j2ee-struts2-spring4-hibernate4
  1.0-SNAPSHOT
  war

  
    
    UTF-8
    
    4.0.3.RELEASE
    
    2.5.26
    
    4.3.5.Final
    
    3.1.1
  

  
    
    
      org.springframework
      spring-core
      ${spring.version}
    

    
      org.springframework

      org.springframework
      spring-orm
      ${spring.version}
    

    
      org.springframework
      spring-tx
      ${spring.version}
    
    

    
    
      org.apache.struts
      struts2-core
      ${struts2.version}
    

    
      org.apache.struts
      struts2-spring-plugin
      ${struts2.version}
    

    
      org.apache.struts
      struts2-convention-plugin
      ${struts2.version}
    

    
      org.apache.struts
      struts2-json-plugin
      ${struts2.version}
    
    

    
    
      org.hibernate
      hibernate-core
      ${hibernate.version}
    

    
      org.hibernate
      hibernate-ehcache
      ${hibernate.version}
    
    

    
    
      org.mybatis
      mybatis
      ${mybatis.version}
    

    
      org.mybatis
      mybatis-spring
      1.2.2
    
    

    
    
      org.apache.openejb

      provided
    

    
      javax.faces
      jsf-api

      provided
    

    
      javax.servlet
      jstl

      javax.servlet.jsp

          1.6
          1.6
        
      
    
  

二、设计目录结构

（1）在项目目录 “/src/main/java”新建“org.example”包名，里面再新建“action，dao，entity，service，utils”目录

（2）在项目目录 “/src/main”新建“webapp”包目录，里面再新建“views/jsp，WEB_INF”目录

（3）在项目目录 “/src/main/resource”新建“spring，struts，hibernate，config”目录

三、实现项目模块

（1）在webapp目录下放置一个index.jsp文件

（2）在webapp/WEB_INF目录下放置一个web.xml文件

  我爱你

      platform-web.xml,struts-default.xml,struts-plugin.xml,struts/struts.xml
    
  

  
    struts2
    /*
  

（3）在webapp/views/jsp目录下放置一个success.jsp，error.jsp，login.jsp，home.jsp

success.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>

            尊敬的匿名用户，
        

        欢迎来到前台系统首页 ~
    

（4）在resource/struts目录下放置struts.xml，struts-hi.xml

    
    

    
    

    
    

    
    
        
        
            /views/jsp/success.jsp
            /views/jsp/error.jsp
        

        
        

        
        

        
        

        
        
    

    
    

    
    
        
            
        

        
            
        
    

struts-hi.xml

    
        
        
            /views/jsp/success.jsp
            /views/jsp/error.jsp
        
    

（5）在resource/spring目录下放置applicationContext.xml

（6）实现具体代码
