I'm using Spring and wanted to know how I can return @Repository and / or @Service exception errors for my webservice?
I have the following structure:
[ Webservice ] ------ [ @service/@Transactional ] ------- [ @Repository ]
When throwing some exception in my DAO what is the elegant way to treat and return to my webservice?
It depends on the webservice, if it is SOAP you will generate a FAULT as a response ... In general this is already mapped automatically when you generate the stubs ... If you are using pure http, rest, simply return a status that is in agreement with the error. For example: 500 to say that an unexpected error occurred, 400 to indicate bad parameters ...
