Is it possible to conditionally assign the value of Required in @RequestParam?

[Mason Wyatt]

I have 2 @RequestParam parameters in my Controller. I want to set the Required value of both the parameters based on a Condition. The condition could be like, if one of the parameter is passed, the other has to passed. So set the required of other as true and vice-versa. Otherwise set both false if none of the parameters are passed.

@RestController
public class TestController {

@GetMapping("/test")
public void test(@RequestParam(value = "a", required = (b !=null) String a, 
@RequestParam(value = "b", required = (a !=null) )  String b,) {
     {

     }

}

The syntax of using the variable name inside @RequestParam() is wrong, but I wanted to explain what I want.

You wouldn't set the condition in your controller where you get them, but where you set them. I would use a differeent request url for the both cases, so your controller that handles the request knows if he should expect parameters or not.
