java - spring-boot如何将手机设为ID

Question

我怎样才能确保只有电话和消息被发送到我的数据库，因为现在我也有成功保存的每个请求的 ID。我想让手机成为唯一标识符，通过它可以在数据库中比较重复值。

如何将手机作为身份证。

用户 Controller

@RestController
@RequestMapping("/users")
public class UserController {
    @Autowired
    private UserRepo userRepo;
    @PostMapping(consumes = {MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE})
    public String createUser(@Valid @RequestBody User requestUserDetails) {
        userRepo.save(requestUserDetails);

        return "The message delivered.";
    }
}

用户

    @Entity
@Table(name = "ApiTable", schema = "TestApi")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;

    private String phone;

    private String message;


    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getMessage() {
        return message;
    }

    public void setLastName(String message) {
        this.message = message;
    }
}

申请

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

用户库

public interface UserRepo extends CrudRepository<User, Long> {

Answer 1

以下是根据您的示例将 phone 字段设为 Id 的方法:

@Entity
@Table(name = "ApiTable", schema = "TestApi")
public class User {

    @Id   
    private String phone;

    private String message;

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getMessage() {
        return message;
    }

    public void setLastName(String message) {
        this.message = message;
    }
}

您的存储库将如下所示:

public interface UserRepo extends CrudRepository<User, String> {
}
