创建controller

@RestController
@RequestMapping(value = "postgres")
public class PostgresController {

    private final UserRepository userRepository;

    public PostgresController(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    @PostMapping(value = "add")
    public String addUser(String name) {
        User user = new User();
        user.setName(name);
        user.setAddr("chongqing");
        userRepository.save(user);
