Spring boot RequestBody with object fields that could be needed

问题

以下是您要求的翻译内容：

如何使我的 RequestBody 能够接受具有可能包含或不包含的对象字段的模型？

这是我正在调用的 RestController 端点：

  1. @PatchMapping(value = "/projects/update/{projectNumber}")
  2. public ResponseEntity<Object> updateProject(@PathVariable int projectNumber, @RequestBody RequestReviewUpdate rru)
  3. {
  4.     return reviewUpdateService.updateReview(projectNumber, rru);
  5. }

这是 @RequestBody 正在接受的模型：

  1. public class RequestReviewUpdate
  2. {
  3.     private UpdateProject project;
  4.     private List<UpdateHlsd> reviews;
  5.     private List<UpdateProjectLeadership> stakeHolders;
  6.     
  7.     public UpdateProject getProject() 
  8.     {
  9.         return project;
  10.     }
  11.     
  12.     public List<UpdateHlsd> getReviews() 
  13.     {
  14.         return reviews;
  15.     }
  16.     
  17.     public List<UpdateProjectLeadership> getStakeHolders() 
  18.     {
  19.         return stakeHolders;
  20.     }
  21.     
  22. }

我希望能够发送一个 JSON，其中可以包含所有对象字段，也可以是其中一些。

我的 JSON 主体可能如下所示：

  1. {
  2.     "project": {
  3.         "type": "HLSD"
  4.     },
  5.     "reviews": [
  6.         {
  7.             "id": 570,
  8.             "requestedBy": "Name here",
  9.             "notes": "test"
  10.         }
  11.     ],
  12.     "stakeHolders": [
  13.         {
  14.             "id": 1088,
  15.             "projectResource": "sid"
  16.         }
  17.     ]
  18. }

或者像这样：

  1. {
  2.     "reviews": [
  3.         {
  4.             "id": 570,
  5.             "requestedBy": "name",
  6.             "notes": "test"
  7.         }
  8.     ]
  9. }

或任何其他可能的组合。

英文:

How can I make my RequestBody accept a model with object fields that may or may not be included?

This is the Restcontroller endpoint I’m calling

  1. @PatchMapping(value = &quot;/projects/update/{projectNumber}&quot;)
  2. public ResponseEntity&lt;Object&gt; updateProject(@PathVariable int projectNumber, @RequestBody RequestReviewUpdate rru)
  3. {
  4. 	return reviewUpdateService.updateReview(projectNumber, rru);	
  5. }

Here is the model @RequestBody is accepting

  1. public class RequestReviewUpdate
  2. {
  3. 	private UpdateProject project;
  4. 	private List&lt;UpdateHlsd&gt; reviews;
  5. 	private List&lt;UpdateProjectLeadership&gt; stakeHolders;
  6. 	
  7. 	public UpdateProject getProject() 
  8. 	{
  9. 		return project;
  10. 	}
  11. 	
  12. 	public List&lt;UpdateHlsd&gt; getReviews() 
  13. 	{
  14. 		return reviews;
  15. 	}
  16. 	
  17. 	public List&lt;UpdateProjectLeadership&gt; getStakeHolders() 
  18. 	{
  19. 		return stakeHolders;
  20. 	}
  21. 	
  22. }

I want to be able to send a JSON could contain all object field, or some.

My JSON body could look something like this...

  1. {
  2.     &quot;project&quot;: {
  3.         &quot;type&quot;: &quot;HLSD&quot;
  4.     },
  5.     &quot;reviews&quot;: [
  6.         {
  7.             &quot;id&quot;: 570,
  8.             &quot;requestedBy&quot;: &quot;Name here&quot;,
  9.             &quot;notes&quot;:&quot;test&quot;
  10.         }
  11.         ],
  12.     &quot;stakeHolders&quot;: [
  13.         {
  14.             &quot;id&quot;: 1088,
  15.             &quot;projectResource&quot;: &quot;sid&quot;
  16.         }
  17.     ]
  18. }

Or this...ect

  1. {
  2.     &quot;reviews&quot;: [
  3.         {
  4.             &quot;id&quot;: 570,
  5.             &quot;requestedBy&quot;: &quot;name&quot;,
  6.             &quot;notes&quot;:&quot;test&quot;
  7.         }
  8.  }

Or any other possible combinations.

只需将您的 RequestReviewUpdate 设置为可选，如下所示：

  1. @PatchMapping(value = "/projects/update/{projectNumber}")
  2. public ResponseEntity<Object> updateProject(@PathVariable int projectNumber, @RequestBody(required=false) RequestReviewUpdate rru) {
  3.     return reviewUpdateService.updateReview(projectNumber, rru);    
  4. }

这将使您的参数变为可选，可以完全或部分地省略。也就是说，作为参数接收的对象的任何成员都可能存在或不存在。

英文:

Just make your RequestReviewUpdate optional, like:

  1. @PatchMapping(value = &quot;/projects/update/{projectNumber}&quot;)
  2. public ResponseEntity&lt;Object&gt; updateProject(@PathVariable int projectNumber, @RequestBody(required=false) RequestReviewUpdate rru) {
  3.     return reviewUpdateService.updateReview(projectNumber, rru);    
  4. }

This will make your parameter optional, either entirely or partially. I.e. any member of the object you receive as an argument, might be present or absent.
