Struts配置应用1

一.导包

<dependency>
  <groupId>org.apache.struts</groupId>
  <artifactId>struts2-core</artifactId>
  <version>2.5.13</version>
</dependency>
二.配置struts.xml文件

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
        "http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>
    <package name="default" extends="struts-default" namespace="/">
        <action name="demo" class="com.yztc.demo.action.DemoAction">
            <result name="index" >index.jsp</result>
        </action>
    </package>
</struts>

三.配置web.xml文件

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
           version="3.1">
  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

四.创建一个class继承ActionSupport,如下:

package com.yztc.demo.action;

import com.opensymphony.xwork2.ActionSupport;

/**
 * _ooOoo_
 * o8888888o
 * 88" . "88
 * (| -_- |)
 * O = /O
 * ___/`---'\____
 * .   ' \| |// `.
 * / \||| : |||// 
 * / _||||| -:- |||||- 
 * | | \ - /// | |
 * | \_| ''---/'' | |
 *  .-\__ `-` ___/-. /
 * ___`. .' /--.-- `. . __
 * ."" '< `.___\_<|>_/___.' >'"".
 * | | : `- \`.;` _ /`;.`/ - ` : | |
 *   `-. \_ __ /__ _/ .-` / /
 * ======`-.____`-.___\_____/___.-`____.-'======
 * `=---='
 * .............................................

public class DemoAction extends ActionSupport {
    @Override
    public String execute() throws Exception {
        System.out.println("你死不死啊!!!");
        return "index";
    }
}
