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
