Stacktrace of exceptions in Spring Rest responses

Spring provides an out of the box solution to handle all your custom exceptions from a single point. What you need is @ControllerAdvice annotation in your exception controller:

@ControllerAdvice
public class GlobalDefaultExceptionHandler {

    @ExceptionHandler(Exception.class)
    public String exception(Exception e) {

        return "error";
    }
}

If you want to go deep into Springs @ExceptionHandler at individual controller level or @ControllerAdvice at global application level here is a good blog.
