Spring-mvc controller and exception handling

Question

Would like to ask you a best practice question where a spring-mvc controller is concerned. Please review the code below:

    @Autowired
    SomeService service;
         


        

Answer 1

I would say best practice would be to use @ExceptionHandler. As the downside to handling the exception in the controller method is that it makes the code less readable and might be repeated across many controller methods.

I would recommend having a base class for your controllers with the @ExceptionHandler defined. This way it can be used for many different controllers, without any code duplication. This would be more readable than the exception resolver approach, but could be used in conjunction.
