How to get Custom object in java spring?

I'm using java spring for my server.



My question is how can I get custom object through the controller.



Example for what I mean:



I know I can do that by doing two functions:



      @RequestMapping(
path = arrayOf("getObject", "getObject/"),
method = arrayOf(RequestMethod.GET))
open fun getRecord1(@RequestBody data: CustomObjectOption1): ResponseEntity<*> {
return ResponseEntity<Any>(data.name,HttpStatus.OK)

}

@RequestMapping(
path = arrayOf("getObject", "getObject/"),
method = arrayOf(RequestMethod.GET))
open fun getRecord2(@RequestBody data: CustomObjectOption2): ResponseEntity<*> {
return ResponseEntity<Any>(data.number,HttpStatus.OK)

}


but I want to do it by only one endpoint:



 @RequestMapping(
path = arrayOf("getObject", "getObject/"),
method = arrayOf(RequestMethod.GET))
open fun getRecord(@RequestBody data: CustomObjectOption): ResponseEntity<*> {

if(data instance option1)
return ResponseEntity<Any>(data.name,HttpStatus.OK)


else
return ResponseEntity(data.number,HttpStatus.OK)
else
}



such that the object can be like this:



option 1:



  public class CustomObject {

private String name;
private Long id;

}


or option 2:



     public class CustomObject {

private List<Integer> number;
private List<Long> count;

}


Is that possible to do that in java spring?



The only solution I was thinking is to use inheritance but I would like to know if there's different way...



Thank you for the help

  • @JBNizet can you tell me what you don't understand? in general I'm trying to pass to the controller the same object but I want that this object could be from type A or from type B

  • Just don't. There is no good reason to send two completely different objects to the same resource. Create two different controller (or controller methods), doing two different things, and accepting two different types of objects.

  • Also, using GET to send a request body doesn't make any sense. GET requests don't have a body.

  • As far as I know if you give it the proper Json it should map it to Object without any problem. Just add the annotation @RestController for the whole controller class
