Spring boot. Map request to object if field isnt there

Suppose I make a get request to foo() with the JSON body:

{
    „a“: „hallo“,
    „b“: „world“,
    „aa“: 10
}


    @PostMapping("/foo")
    public void foo(@RequestBody MyClass myClass) {
        //do stuff
    }

class MyClass {
  
    String a;
    String b;
    String c;
    int aa;

}

If the JSON object and the class match, then it works fine and you get a MyClass object with the correct variables set. But now I want to set only those fields in the MyClass class that I have also passed and the rest is initialized with null. How can I do this?

you have to change @GetMapping to @PostMapping if you want to use @RequestBody.
