Not sure that this is the right way to do but I think it's ok as a workaround. You can implement a setter method where you can add the @PathVariable annotation. If you apply this approach it would make sens to have a dedicated request object.

public class UserDto {
  private Long id;
  private String name;
  
  public void setId(@PathVariable Long Id) {
    this.id = id;
  }

}

If there is a better solution I did not find please link it.
