想问一个关于spring-mvc控制器的最佳实践问题。请查看以下代码：

    @Autowired
    SomeService service;

    @RequestMapping (...)
    public @ResponseBody Response createSomething () {

       try {

            serviceResponse = service.doSomething();

            //create a success response and return

       }
       catch (SomeServiceException e) {
             //create an error response and return 
       }

}

错误处理是在控制器级别上进行的吗？还是服务类不应引发如上所示的异常。请查看并告知我。
