ProtoApplication

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.transaction.annotation.Transactional;

@EntityScan("com.example.model")
@Transactional
public class ProtoApplication extends SpringBootServletInitializer {

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(ProtoApplication.class);
    }

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

}

用户控制器

package com.example.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PostMapping;

import com.example.model.User;
import com.example.service.UserService;

@Controller
public class UserController {
    @Autowired
    private UserService serv;

    @GetMapping("/user")
    public String getUser(@ModelAttribute("user") User us) {
        System.out.println("Inside UserController");
        return "user";
    }

    @PostMapping("/saveUser")
    public String postUser(@ModelAttribute("user") User us, BindingResult result, ModelMap map) {
        serv.serUser(us);
        map.put("user", us);

        return "user";
    }
}

UserService

package com.example.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.example.model.User;
import com.example.repository.UserRepository;

@Service
public class UserService {
    @Autowired
    private UserRepository repo;

    public void serUser(User us) {
        System.out.println("Inside User Service");
        repo.save(us);

    }

}

用户存储库

package com.example.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import com.example.model.User;

@Repository
public interface UserRepository extends JpaRepository<User, String> {
    

}

应用程序属性

spring.datasource.url= jdbc:mysql://localhost:3306/springboot
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.hibernate.ddl-auto=create-drop
server.port=8080
spring.mvc.view.prefix:/WEB-INF/jsp/
spring.mvc.view.suffix:.jsp

在使用@EnableJpaRepository. 在此之前，我一直使用它直到 UserController 的@GetMapping，它把我带到了user.jsp. 但是从我使用 JPA 的那一刻起，它不起作用，我搜索了解决方案，但到处都是使用 spring-tx，我做到了，它甚至在我的库中，但仍然无法弄清楚。所以请如果有人可以帮助我。
