Spring MVC Best Practice Handling Unrecoverable Exceptions In Controller

Question

When you have a controller that does logic with services and DAO\'s that may throw an unrecoverable exception, what is the best practice in dealing with those method calls?<

Answer 1

Check out the @ExceptionHandler

You can use it like

@ExceptionHandler(IOException.class)
@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public void handleExc(IOException ext) {}

That would catch all IOExceptions thrown by the controller method and write out a 500 to the response.
