java-ee Java RESTful Web Services (JAX-RS) Exception Mapper
Example
@Provider
public class IllegalArgumentExceptionMapper implements ExceptionMapper<IllegalArgumentException> {
@Override
public Response toResponse(IllegalArgumentException exception) {
return Response.serverError().entity("Invalid input: " + exception.getMessage()).build();
}
}
This exception mapper will catch all IllegalArgumentExceptions thrown in the application, and show the user a clear message instead of a stacktrace.
