Java – not all exceptions are mapped to resolveexception in simplemappingexceptionresolver

2020-08-02 • Java

I override resolveexception in simplemappingexceptionresolver to send an e-mail containing stacktrace. The e-mail applies to 500 errors, but 400 errors do not reach this method (there is no stack trace to send, but I still want to send an email and display a good error page.)

Is there any way to do this, or should I configure my web XML to process 400 (and similar)?

Solution

I think you will find this answer very helpful:

Spring SimpleMappingExceptionResolver not going to default view

TL; Dr spring exceptionresolvers does not handle all exceptions, only the exceptions thrown by the controller When spring cannot convert the submitted data of the mapping controller, it may throw a "400 - error request", and the exception you throw will never be seen by your exceptionhandler

Your web The XML solution should work well
