struts2配置

struts2配置

首先在web.xml中引入Struts2的拦截器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 
    id="WebApp_ID" version="3.1">
  <display-name>Archetype Created Web Application</display-name>
  <filter>
         <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
        <!--指定Struts2配置文件的位置-->
         <init-param>  
        <param-name>filterConfig</param-name>  
        <param-value>struts.xml</param-value>  
    </init-param>
    </filter>
    <filter-mapping>
         <filter-name>struts2</filter-name>
         <url-pattern>/*</url-pattern>
     </filter-mapping>
</web-app>

添加struts2配置文件struts2.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
    <package name="default" namespace="/" extends="struts-default">
    </package>
    <!-- 开启调试模式 -->
    <constant name="struts.devMode" value="true"/>
    <include file="struts-userAction.xml"></include>
</struts>

配置action的映射文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
    <package name="userAction" namespace="/" extends="struts-default">
        <action name="*" class="com.jimmyqin.action.UserAction" method="{1}">
            <result name="list">/WEB-INF/index.jsp</result>
        </action>
    </package>
</struts>

在maven的pom.xml配置文件中添加Struts2依赖

 <!-- Struts2依赖包 -->
<dependency>  
      <groupId>org.apache.struts</groupId>  
      <artifactId>struts2-core</artifactId>  
      <version>2.3.1.2</version>  
</dependency>
