一，创建项目

二，后端代码

1.bean层

User类

package com.wang.bean;

public class User {
    private Integer id;
    private String name;
    private String password;

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", password='" + password + '\'' +
                '}';
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

2.controller层

package com.wang.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class TestController {
//    @RequestMapping("/test")
//    public String test(){
//        System.out.println("TestController...test");
//        return "zhuye";
//    }
    @RequestMapping("/login")
    public String login(String name,String password){
        System.out.println("TestController...test");
        System.out.println(name);
        System.out.println(password);
        return "zhuye";
    }
}
