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:
