public class ExceptionHandlerExceptionResolver extends AbstractHandlerMethodExceptionResolver implements ApplicationContextAware, InitializingBean
AbstractHandlerMethodExceptionResolver
that resolves exceptions
through @ExceptionHandler
methods.
Support for custom argument and return value types can be added via
setCustomArgumentResolvers(java.util.List<org.springframework.web.method.support.HandlerMethodArgumentResolver>)
and setCustomReturnValueHandlers(java.util.List<org.springframework.web.method.support.HandlerMethodReturnValueHandler>)
.
Or alternatively to re-configure all argument and return value types use
setArgumentResolvers(java.util.List<org.springframework.web.method.support.HandlerMethodArgumentResolver>)
and setReturnValueHandlers(List)
.
