Java 错误：从Spring Boot和SQL Server生成的API中获取的列表记录重复

我在SQL Server中创建了一个存储过程，它工作正常，如下所示：

exec udf_get_gio_hang_by_id_khach_hang @id_khach_hang='KH00003368'

结果是2条记录，如下所示：

exec udf_get_gio_hang_by_id_khach_hang @id_khach_hang='KH00003368'

我的目的是创建一个API来获取上述记录的列表。因此，我通过Spring Boot创建API，如下所示： 首先，我创建了一个模型

GioHang.java

@Entity
public class GioHang implements Serializable {
    
    @Id
    private String id_khach_hang;
    
    
    private String id_xe;
    private int so_luong;
    
    //setter,getter

}

@Repository
public interface GioHangRepo extends JpaRepository<GioHang,String> {
@Query(value = "{call udf_get_gio_hang_by_id_khach_hang(:id_khach_hang)}",nativeQuery = true)
    public List<GioHang> get_list_gio_hang_via_id_khach_hang(@Param("id_khach_hang")  String id_khach_hang);
}

@Service
@Transactional
public class GioHangService {
    @Autowired
    private GioHangRepo gioHangRepo;

    public List<GioHang> getGioHangById_khach_hang(String id_khach_hang)
    {
        return this.gioHangRepo.get_list_gio_hang_via_id_khach_hang(id_khach_hang);
    }
}

@RestController
@RequestMapping("/gio_hang")
public class GioHangResource {
    @Autowired
    private GioHangService gioHangService;
    
    @GetMapping("/getGioHangById_khach_hang/{id_khach_hang}")
    public ResponseEntity<List<GioHang>> getGioHangById(@PathVariable("id_khach_hang") String id_khach_hang)
    {
        List<GioHang> gh = this.gioHangService.getGioHangById_khach_hang(id_khach_hang);
        return new ResponseEntity<>(gh,HttpStatus.OK);
    }
}

然后我创建了一个存储库接口

GioHangRepo.java

@Entity
public class GioHang implements Serializable {
    
    @Id
    private String id_khach_hang;
    
    
    private String id_xe;
    private int so_luong;
    
    //setter,getter

}

@Repository
public interface GioHangRepo extends JpaRepository<GioHang,String> {
@Query(value = "{call udf_get_gio_hang_by_id_khach_hang(:id_khach_hang)}",nativeQuery = true)
    public List<GioHang> get_list_gio_hang_via_id_khach_hang(@Param("id_khach_hang")  String id_khach_hang);
}

@Service
@Transactional
public class GioHangService {
    @Autowired
    private GioHangRepo gioHangRepo;

    public List<GioHang> getGioHangById_khach_hang(String id_khach_hang)
    {
        return this.gioHangRepo.get_list_gio_hang_via_id_khach_hang(id_khach_hang);
    }
}

@RestController
@RequestMapping("/gio_hang")
public class GioHangResource {
    @Autowired
    private GioHangService gioHangService;
    
    @GetMapping("/getGioHangById_khach_hang/{id_khach_hang}")
    public ResponseEntity<List<GioHang>> getGioHangById(@PathVariable("id_khach_hang") String id_khach_hang)
    {
        List<GioHang> gh = this.gioHangService.getGioHangById_khach_hang(id_khach_hang);
        return new ResponseEntity<>(gh,HttpStatus.OK);
    }
}

最后，我在

GioHangResource.java

@Entity
public class GioHang implements Serializable {
    
    @Id
    private String id_khach_hang;
    
    
    private String id_xe;
    private int so_luong;
    
    //setter,getter

}

@Repository
public interface GioHangRepo extends JpaRepository<GioHang,String> {
@Query(value = "{call udf_get_gio_hang_by_id_khach_hang(:id_khach_hang)}",nativeQuery = true)
    public List<GioHang> get_list_gio_hang_via_id_khach_hang(@Param("id_khach_hang")  String id_khach_hang);
}

@Service
@Transactional
public class GioHangService {
    @Autowired
    private GioHangRepo gioHangRepo;

    public List<GioHang> getGioHangById_khach_hang(String id_khach_hang)
    {
        return this.gioHangRepo.get_list_gio_hang_via_id_khach_hang(id_khach_hang);
    }
}

@RestController
@RequestMapping("/gio_hang")
public class GioHangResource {
    @Autowired
    private GioHangService gioHangService;
    
    @GetMapping("/getGioHangById_khach_hang/{id_khach_hang}")
    public ResponseEntity<List<GioHang>> getGioHangById(@PathVariable("id_khach_hang") String id_khach_hang)
    {
        List<GioHang> gh = this.gioHangService.getGioHangById_khach_hang(id_khach_hang);
        return new ResponseEntity<>(gh,HttpStatus.OK);
    }
}

@RestController
@请求映射（“/gio_hang”）
公共类资源{
@自动连线
私人GIONHANGSERVICE GIONHANGSERVICE；
@GetMapping（“/getGioHangById\u khach\u hang/{id\u khach\u hang}”）
公共响应getGioHangById（@PathVariable（“id_khach_hang”）字符串id_khach_hang）
{
List gh=this.gioHangService.getGioHangById_khach_hang（id_khach_hang）；
返回新的响应状态（gh、HttpStatus.OK）；
}
}

我在swagger中测试API，但得到了如下重复记录列表：

exec udf_get_gio_hang_by_id_khach_hang @id_khach_hang='KH00003368'

我不知道为什么列表中的记录都和第一条记录一样

请帮帮我。

我认为问题与您使用

id\u khach\u hang

作为主键有关，主键应该是唯一的，在您的情况下不会发生这种情况。您应该有一个具有唯一值的列，并将其用于@Id属性

---

另外，在用java编写代码时，请不要使用snake符号，这会使事情变得非常难看和难以理解。

我想这个错误是因为我在SQL Server中为

id\u khach\u hang

和

id\u xe

设置了primary，但只为其中一个设置了

@id

如果： 解决方案1：为

Id\u khach\u hang

和

Id\u xe

---

解决方案2：您可以添加另一个列，如

Id\u record

，然后为其生成主键，并为

Id\u khach\u hang

和

Id\u xe

生成外键。记住

Id\u record

的make

/Id>是的，这是我想要的。谢谢
