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，但是以前的项目是使用MyEclipse或者Eclipse工具来开发的，而且还是外部引入依赖包，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）GroupId：org.example
（2）ArtifactId：j2ee-struts2-spring4-hibernate4
（3）Project name：j2ee-struts2-spring4-hibernate4
（4）Project location：D:\idea_workspace\j2ee-struts2-spring4-hibernate4

  二、引入SSH依赖库

（1）pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <groupId>org.example</groupId>
  <artifactId>j2ee-struts2-spring4-hibernate4</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>war</packaging>

      </plugin>
    </plugins>
  </build>

</project>

三、设计目录结构

（1）创建好相关模块，设计出一个良好的项目基本结构

 四、新建一个 web.xml 配置文件

（1）在 j2ee-struts2-spring4-hibernate4/src/main/webapp/WEB_INF 目录中新建 web.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
  http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

  <display-name>我爱你</display-name>

  <welcome-file-list>
    <!-- 若欢迎页不填写 index.jsp/welcome.jsp 等，则到 struts.xml 找默认的 action，若填写了 index.jsp/welcome.jsp 等，则优先级比 struts.xml 中默认的 action 还高 -->
    <welcome-file>welcome.jsp</welcome-file>
  </welcome-file-list>

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring/applicationContext.xml,classpath:spring/**/applicationContext*.xml</param-value>
  </context-param>

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <filter>
    <filter-name>struts2</filter-name>

    <!-- struts2 版本为 2.3.16.1 -->
    <!-- <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> -->

    <!-- struts2 版本为 2.5.26 -->
    <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>

    <init-param>
      <param-name>config</param-name>
      <!-- 此处可以填写自定义的 struts-*.xml 配置文件，如：struts/struts-hi.xml，若不写亦可在 struts.xml 文件中使用 include 标签导入 -->
      <param-value>platform-web.xml,struts-default.xml,struts-plugin.xml,struts/struts.xml</param-value>
    </init-param>
  </filter>

  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

（2）记得在 Project Structure 中为 Web 添加 web.xml 文件

 五、新建一个 welcome.jsp 欢迎页面

（1）在 j2ee-struts2-spring4-hibernate4/src/main/webapp 目录中新建 web.xml 文件

    <div style="width: 100%; height: 100%; display: grid; align-items: center; text-align: center">
        <span style="color: #303133; font-size: 14px;">你好，世界！ ...</span>
    </div>
</body>
</html>

六、新建四个 jsp 测试页面

（1）在 j2ee-struts2-spring4-hibernate4/src/main/webapp/view/jsp 目录中依次创建 success.jsp、error.jsp、login.jsp、home.jsp 作为测试使用
（2）success.jsp

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

<body>
    <div style="width: 100%; height: 100%; display: grid; align-items: center; text-align: center">
        <p>
            <span style="color: #303133; font-size: 14px;">你好，${request.username}</span>
        </p>
    </div>
</body>
</html>

（2）error.jsp

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