exception handler method in #ControllerAdvice are not get called - spring

Question

I'm test my controller using junit5. In test method, EntityNotFoundException is throwed but exception handler is not called.
I have tried declaring ExceptionHandlerExceptionResolver bean with order 1. But it didn't works.
Exception handler which handles EntityNotFoundException:
#ControllerAdvice
#EnableWebMvc
public class AppWideExceptionHandler {
#ExceptionHandler(EntityNotFoundException.class)
public #ResponseBody
String handleEntityNotFoundException(EntityNotFoundException e) {
return "test";
}
...
}
The AppWideExceptionHandler is in youshu.exception package which will be scanned because of #ComponentScan({"youshu.controller", "youshu.service","youshu.exception"}) annotated on WebConfig class.
The processRefundApplication controller method calls RefundService.get(String orderID) which may throw EntityNotFoundException:
#Controller
#RequestMapping("/Order")
public class OrderController {
#AsSeller
#RequestMapping(value = "/{orderID}/RefundApplication",
method = RequestMethod.PATCH,
params = "isApproved",
produces = "application/json")
#Transactional(rollbackFor = RuntimeException.class)
public #ResponseBody
Map processRefundApplication(#SessionAttribute("user") User user,
#PathVariable("orderID") String orderID,
#RequestParam("isApproved") boolean isApproved) {
...
}

Answer 1

You need to point your mockMvc instance to your controller advice class:
#Autowired
AppWideExceptionHandler exceptionHandler;
...
mockMvc = standaloneSetup(controller).setControllerAdvice(exceptionHandler).build();
