如何在spring boot中将数据从模型插入到表中

public class User {
    private Long id;
    private String name;
    // 其他属性和对应的getter/setter方法
}

public interface UserRepository extends JpaRepository<User, Long> {
    // 插入数据的方法
    User save(User user);
}

@Repository
public class UserRepositoryImpl implements UserRepository {
    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public User save(User user) {
        entityManager.persist(user);
        return user;
    }
}

spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

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

    public void insertUser(User user) {
        userRepository.save(user);
    }
}

@RestController
public class UserController {
    @Autowired
    private UserService userService;

    @PostMapping("/users")
    public void createUser(@RequestBody User user) {
        userService.insertUser(user);
    }
}
