Springboot+MySQL登录注册后端逻辑模板

为了节省后端开发时间，自己写了一个后端模板，开箱即用，包括登录注册两个功能

这个是启动类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class LoginRegisterApplication {

    public static void main(String[] args) {
        SpringApplication.run(LoginRegisterApplication.class, args);
    }

}

这个是控制类

import com.example.login_register.entity.User;
import com.example.login_register.service.UserService;
import jakarta.servlet.http.HttpSession;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;


@Controller
public class UserController {

    @Autowired
    private UserServi
