表单Form中的action怎么填（Struts篇）

来源：互联网发布：无标度网络是什么意思编辑：程序博客网时间：2024/04/29 23:59

今天突然发现，form中的action=“/login”居然是错误的。突发奇想，就想对url做个探究。
还有好多人是用${requestScope….}，我也想做个实验，加深影响。
继续探究吧，想看最后结论，请下拉…（记得点赞，谢谢！）

Action:

package com.stu;import java.util.Date;import com.opensymphony.xwork2.ActionSupport;public class UserAction extends ActionSupport {    private User user;    public void setUser(User user) {        this.user = user;    }    public User getUser() {        return user;    }    public String Login(){        System.out.println("In login: ");        System.out.println("id: "+user.getId());        System.out.println("pw: "+user.getPw());        System.out.println("age: "+user.getPw());        return SUCCESS;    }}

Struts.xml:

    <package name="convert" extends="struts-default" namespace="/">        <action class="com.stu.UserAction" name="Login" method="Login">            <result name="success">/success.jsp</result>        </action>    </package>

success.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <title>My JSP 'success.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>    This is my Success page.!!!! <br>  </body></html>

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <title>My JSP 'login.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 action="Login" method="post">        用户名：<input type="text" name="user.id" /><br/>        密码：<input type="text" name="user.pw" /><br/>        年龄：<input type="text" name="user.age" /><br/>        <input type="submit" value="提交"/>    </form> <br>  </body></html>

好吧，接下来我们在login.jsp中下文章咯：

Action 在默认命名空间下。

（明日更新！！！）
