Struts2入门示例(Myeclipse)

1.新建Web项目在lib导入struts-2.3.37核心基础jar包

2.在WebRoot新建2个JSP

demo1.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <title>Struts2入门</title>

  </head>

  <body>

      <h1>Struts入门</h1>

      <a href="${pageContext.request.contextPath }/strutsDemo1.action">访问Struts的action</a>

  </body>

</html>

demo2.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

  </head>

  <body>

      <h1>跳转成功！</h1>

  </body>

</html>

3.在项目中的web.xml中添加代码

<filter>

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

        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

</filter>

<filter-mapping>

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

       <url-pattern>/*</url-pattern>

</filter-mapping>

4.建包建类

package com.sve.struts2;

public class Demo1 {

    public String execute() {

        System.out.println("方法执行了");

        return "success";

    }

}

注意：方法名必须为execute，返回值必须为String，且public

5.在src下创建struts.xml

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

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

    "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

    <package name="demo" namespace="/" extends="struts-default">

        <action name="strutsDemo1" class="com.sve.struts2.Demo1">

            <result name="success">/demo2.jsp</result>

        </action>

    </package>

</struts>

在action中class为你建包名.类名，name为demo1.jsp中访问链接，无须加.action

在result中，name的值为类中的返回值
