Struts2环境搭建和运用

一、解压\struts-2.3.31\apps路径下struts2-blank.rar文件。将其中WEB-INFl路径下的lib中的包和web.xml文件复制到新项目中的WEB-INF路径下。web.xml中的配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <display-name>Struts Blank</display-name>

    <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>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

</web-app>

二、struts2-blank.rar解压文件src中的strus.xml文件复制到新项目中的src目录下，配置如下：

<?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>

    <constant name="struts.enable.DynamicMethodInvocation" value="false" />
    <constant name="struts.devMode" value="true" />

    <package name="default" namespace="/" extends="struts-default">
        <action name="index" class="com.itnba.maya.controller.IndexAction">//class中路径与对应控制接收数据的类
            <result>//与IndexAction中return对应，当return success时，name可以不填
              index.jsp//跳转到index.jsp页面
            </result>
            <result name="error">//当return error时
              index_error.jsp
            </result>
            <result name="haha">//自定义的 return "haha"
              index_haha.jsp
            </result>
        </action>
        <action name="home">
             <result>
              home.jsp
             </result>
        </action>
    </package>
    
    <!-- Add packages here -->

在src路径下建立一个包com.itnba.maya.controller，在其中建立一个IndexAction类配置如下：

package com.itnba.maya.controller;

import com.opensymphony.xwork2.ActionSupport;

public class IndexAction extends ActionSupport {
private String msg;//用get 来接收传过来的值
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
@Override
public String execute() throws Exception {
// TODO 自动生成的方法存根
return SUCCESS;
}
}

 建两个jsp页面index.jsp  reg.jsp

reg.jsp如下

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
<form action="index" method="post">
输入<input type="text" name="msg"><br>
<input type="submit">
</form>
</body>
</html>

index.jsp如下：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
this is index.jsp
${msg }
</body>
</html>

运行reg.jsp 输入 hello world

提交结果如下
