如果我正在编写只有特定列的本机查询，如何使用 Jpa 在 postman 中显示列名

Question

• 我在我的存储库中进行了本机查询，它只给出特定的列 output。

  @Query(value = "SELECT installation_id,description,checklist_steps,creation_date,location,status FROM installation_details", nativeQuery = true) List < Object > findCustomInstallation();

• 但是我在 postman 上得到的响应只向我显示列内的数据，那么我如何也可以显示列名？

• Note:- I am not using my model as it is having one to one mapping of other table also and if I run query using my model it is also showing me data of other table on postman that is why I used Object instead of model.

• 我得到的回应是这样的

> { > "status": 1, > "message": "Successfully Fetched", > "myObjectList": [ > [ > 1, > "traffic project", > "13", > "2021-01-30T06:57:34.000+0000", > "Delhi", > 1 > ],

Answer 1

您可以使用预测来完成这项工作。

创建一个只有 getter 的接口

public interface InstallationDetailsProjection 
{
    Long getInstallation_id();
    String getDescription();
//similar for other fields
}

然后将别名添加到您的本机查询

@Query(value = "SELECT installation_id as installation_id,description as description //more fields
 FROM installation_details", nativeQuery = true) List < InstallationDetailsProjection > findCustomInstallation();

这应该可以解决您的问题。
