环境:myeclipse下
新建一个webproject
框架:
1.导包
2.配置WebRoot下的lib文件里面的web.xml(配置过滤器)
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>com.csdn.struts</display-name>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>//这里最好是/* 也可以是.action
</filter-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
3.在src下面新建一个实体类RegAction.java WebRoot下面新建一个reg.jsp.
(生成get set方法可以在工具栏里面点击Source,里面有generate getters and setters;生成构造方法也有)
RegAction.java
import com.opensymphony.xwork2.ActionSupport;
public class RegAction extends ActionSupport {
private String username;
private String password;
private String phone;
@Override
public String execute() throws Exception {
System.out.print(username+"==="+password+"==="+phone);
return "index";
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
}
reg.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'reg.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<form method="post" action="regAction">//这里的regAction一定要和struts.xml里面的action name一致,表单提交的内容才会给相应的Action处理
姓名:<input type="text" name="username" /><br/>//这里的username要和RegAction里面的属性username一直,否则值也传不到类里面去
密码:<input type="password" name="password"><br/>
电话:<input type="text" name="phone"><br>
<input type="submit" value="注册">
</form>
</body>
</html>
4.新建一个struts.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="base" extends="struts-default">
<action name="regAction" class="com.xzz.action.RegAction">
<result name="index">index.jsp</result>//这里可以跳转到任何页面,我这里只是跳转到index页面
</action>
</package>
</struts>
5.运行
