How can I handle exceptions with Spring Data Rest and the PagingAndSortingRepository?

Question

Let\'s say I have a repository like:

public interface MyRepository extends PagingAndSortingRepository {

    @Query(\"....\")
    Page<

You could use a global @ExceptionHandler with the @ControllerAdvice annotation. Basically, you define which Exception to handle with @ExceptionHandler within the class with @ControllerAdvice annotation, and then you implement what you want to do when that exception is thrown.

Like this:

@ControllerAdvice(basePackageClasses = RepositoryRestExceptionHandler.class)
public class GlobalExceptionHandler {

    @ExceptionHandler({QueryException.class})
    public ResponseEntity> yourExceptionHandler(QueryException e) {
        Map response = new HashMap();
        response.put("message", "Bad Request");
        return new ResponseEntity>(response, HttpStatus.BAD_REQUEST); //Bad Request example
    }
}
