Spring. Map field of @RequestBody with @PathVariable

问题

Now I have code like this:

@RestController
public class ChildController {

@RequestMapping(value = "/parents/{parentId}/addChild", method = RequestMethod.POST)
  public void addChild(@RequestBody ChildDTO child, @PathVariable Long parentId) {
    child.setParentId(parentId);
    //...
  }
}

class ChildDTO {

  private Long parentId;

  private String name;

  private double weight;

  private double height;

  //setters ang getters
}

Is there any way to map parentId in child object without calling setter in method body? I need it for my Aspect @Before logic
