This article will explain in detail how to customize exception handling in springboot. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have some understanding of the relevant knowledge after reading this article.

Global exception handling

1. Define handler

@ RestControllerAdvice

Public class SelfExceptionHandler {

/ * *

* deal with Exception

* @ param e

* @ return

, /

@ ExceptionHandler (Exception. Class)

Public Result handleServiceException (Exception e) {

E.printStackTrace ()

Return new Result (e)

}

}

2. Throw an exception where the business is written

Throw new Exception ("xxx")

To customize exception handling is to customize an exception class, such as BusinessException

Then replace the corresponding place in the handler

@ RestControllerAdvice

Public class SelfExceptionHandler {

/ * *

* deal with Exception

* @ param e

* @ return

, /

@ ExceptionHandler (BusinessException. Class)

Public Result handleServiceException (BusinessException e) {

E.printStackTrace ()

Return new Result (e)

}

}

If you want to render the processing results to the page, you can change @ RestControllerAdvice to @ ControllerAdvice

Then add the following methods:

@ ExceptionHandler (Exception. Class)

Public ModelAndView handleServiceException (Exception e) {

ModelAndView modelAndView = new ModelAndView ()

ModelAndView.setViewName ("500")

ModelAndView.addObject ("code", e.getMessage ())

Return modelAndView

}
