实体类：

package com.example.demo;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

/**
 * 实体类
 * @author linziyu

 */
@Entity(name="table_user")
public class UserEntity {

    @Id
    @GeneratedValue
    private Long id;
    private String username;
    private String password;

    public Long getId() {
        return id;
    }

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

    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;
    }
}

数据操作：

package com.example.demo;


import org.springframework.data.repository.CrudRepository;

import org.springframework.stereotype.Repository;


@Repository
public interface UserDao extends CrudRepository<UserEntity,Long>{
	public UserEntity findByUsernameAndPassword(String username,String password);
}

控制层：

package com.example.demo;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller

@RequestMapping("/front/*")
public class IndexController {
    @Autowired
    private UserDao userDao;

    @RequestMapping("/index")
    public String index() {
        return "index";
    }

    @RequestMapping("/register")
    public String register(){
        return "register";
    }

    @RequestMapping("/addregister")
    public String register(HttpServletRequest request){
        String username = request.getParameter("username");
        String password = request.getParameter("password");
        String password2 = request.getParameter("password2");
        if (password.equals(password2)){
            UserEntity userEntity = new UserEntity();
            userEntity.setUsername(username);
            userEntity.setPassword(password);
            userDao.save(userEntity);
            return "index";
        }else {
            return "register";
        }
    }
    
    @RequestMapping("/login")  
    public String login(){  
        return "login";  
    }  
    
    @RequestMapping("/addlogin")  
    public String login(HttpServletRequest request){  
        String username = request.getParameter("username");  
        String password = request.getParameter("password");  
        UserEntity userEntity = userDao.findByUsernameAndPassword(username,password);  
        String str = "";  
        if (userEntity !=null){  
            str = "index";  
        }else {  
            str = "login";  
        }  
        return str;  
    }  
}
