Class ChenileExceptionHandler

java.lang.Object

org.chenile.core.interceptors.BaseChenileInterceptor

org.chenile.core.interceptors.ChenileExceptionHandler

All Implemented Interfaces:

Command<ChenileExchange>

public class ChenileExceptionHandler
extends BaseChenileInterceptor

Handles all exceptions by: Translating all errors and warnings to international language. (service is assumed to throw just error code and not error message) This can be extended to provide custom functionality. But be sure that the extended exception handler is instantiated in a spring configuration and the name of the spring configuration must be set in chenile.exception.handler in "chenile.properties"

Method Details

doPostProcessing

protected void doPostProcessing(ChenileExchange exchange)

Description copied from class: BaseChenileInterceptor

Override this to do post processing. This will be called even if there is an exception downstream. So make sure that if you don't want to do any processing in case of exception, check if ChenileExchange.getException() returns null value. If you happen to throw an exception in this method, it will get added to the set of errors that would ultimately be returned. See also ChenileExchange.setException(Throwable)

Overrides:
