GlobalExceptionHandler is needed

[jh-orz]

As of my engineering practices, we mostly build a global exception handller to handle Java exceptions generally rather than specificly or seperately. In most cases, building this handler follows sequences that starts from bizExceptions to the throwables. In my opinion, spring boot and such backend framework should provide efficiency that programmers stay focused on the bizes instead of spring exception or runtime exceptions. I'd like to define such handlers with a notation and forget about self-contained exceptions, but, the ultimate implemrntation depends on you.

Exactly how an exception should be handled depends on the context in which it has been caught. For example, you may want the handling of an exception during web request handling to result in an error response being sent but such handling wouldn't be appropriate when processing a JMS message.

I would recommend looking at things like Spring MVC's @ExceptionHandler and the error and exception handling mechanisms provided in other domains such as message processing and task execution.
