How to add the result from a RestController to a custom wrapper object in Spring

Our front end application always expects a certain json format for the result, something like: 

{
success: true,
errors: [],
responseObject: ...
}

Say I want to return a list of users, that list would be a in the responseObject. Now I would like to be able to just return this list from the restcontroller and have something like a controller advice wrap the list in this response object. However as I understand I cannot use the controller advice in this case. Is there a way to do this?

Solution

  • You can use for this purpose Filter. You can get your list of users from the response object, wrap in your desired model structure and change in response.
