I am developing a SOAP web service with CXF 2.3.3. I want to throw a custom exception when user has submitted wrong data. My exception class looks like this.
#WebFault(name="InvalidUserDataException", targetNamespace="http://foo.bar.com/")
#XmlAccessorType(XmlAccessType.FIELD)
public class InvalidUserDataException extends RuntimeException {
public InvalidUserDataException(){
super();
}
String validationErrors;
}
In my method Impl class I purposely throw this exception to see whether SoapFault exception is returned by CXF to client, but whatever I do to any of these classes results in same error: createNewUser has thrown exception, unwinding now.
Note that WSUserRegistration interface also declares itself that createNewUser method throws InvalidUserDataException.
public class WSUserRegistrationImpl implements WSUserRegistration {
#Autowired
IWSUserValidationProxy validationProxyImpl;
#Override
public int createNewUser(RegistrationInputProperty registrationInfo) throws InvalidUserDataException {
if (true) {
throw new InvalidUserDataException();
}
return 1;
}
}
My goal is to catch this exception from a SOAPFaultOutInterceptor and return a customized faultDetail.
How do I make CXF catch this error and return a SOAPFault object? Any ideas?
this would help you.

I have a REST Enspoint
...
#GET
public Response read (#Valid Param parameters) {
}
...
How can I catch this Exception to handle this in Quarkus?
Is there a special Exceptionhandler available?
You can handle the exception by using:
#Provider
public class MyViolationExceptionMapper implements ExceptionMapper<ValidationException> {
#Override
public Response toResponse(ValidationException exception) {
// do something
}
}
You can draw inspiration for how to handle things by looking at the built-in exception mapper.
I do have a Spring boot controller class and a corresponding ControllerAdvice class which has ExceptionHandlers to handle different exception.
My controller method calls a simple validation helper class to validate input fields which throws an exception if validation fails. Now if I don't put a try catch block in my controller it keeps complaining me that you have a method which has untangled exception even through the logic for handling validation exception is defined in controlleradvice class. Please suggest how do I solve it.
From the method of ValidationHelper class if you throw any Checked Exception then you need to use a try-catch block to call that method.
If you don't want then it's better to use any Custom Exception class which will extend the RuntimeException class and you throw that exception. Then you don't need to explicitly mention the throws as well as you don't need to have a try-catch block at the controller.
#RestController
#RequiredArgsConstructor
public class SampleController {
private final ValidationHelper validationHelper;
#ResponseStatus(HttpStatus.OK)
#GetMapping("/sample")
public String getRequest(#RequestParam String name) {
validationHelper.validate(name);
return "";
}
}
#Service
public class ValidationHelper {
public Boolean validate(String name) {
throw new CustomException("Validation Failed");
}
}
public class CustomException extends RuntimeException {
public CustomException(String message) {
super(message);
}
}
is there a way to handle jax-rs validation exception, I mean to not the throwing exception, just sysout my string.
I use #Valid annotation in this way
public function name (#Valid DtoClassName dtoVariableName);
using resteasy 2 and wildfly 19.
I use mapper as previous answers here, but nothing work, it's throw the exception then call the mapper.
#Provider
public class ValidationExceptionMapper implements ExceptionMapper<javax.validation.ConstraintViolationException> {
public ValidationExceptionMapper() {
System.out.println("ValidationExceptionMapper");
// TODO Auto-generated constructor stub
}
#Override
public Response toResponse(ConstraintViolationException exception) {
// TODO Auto-generated method stub
return Response.status(Status.BAD_REQUEST).entity("HELLLO ERROR").build();
}
}
I currently have two ControllerAdvice in my application, I'm supposed to merge them into one.
But I need to test them before and after the merge, test the exception and the object that the controller return me.
I'm trying to make a jUnit test with Mockito but it seems impossible to test the exceptions without any context, without a controller, etc ...
Does anyone know how can I proceed to achieve what I'm trying to do ?
I also try to throw manually an exception but obviously it wasn't catched by the ControllerAdvice.
So basically here is what i'm trying to do:
Manually throw an exception
This exception is handled by my ControllerAdvice
Check the returned object (code & message)
Here is a sample of code I have:
#Before
public void setup() {
...
mockMvc = MockMvcBuilders.standaloneSetup(getController())
.setControllerAdvice(new GlobalControllerExceptionHandler())
.setCustomArgumentResolvers(resolver, resolver_0, resolver_1)
.setHandlerExceptionResolvers(exceptionResolver).build();
}
#Controller
#RequestMapping("/tests")
public static class RestProcessingExceptionThrowingController {
#RequestMapping(value = "/exception", method = GET)
public #ResponseBody String find() {
throw new EntityNotFoundException();
}
}
#Test
public void testHandleException() throws Exception {
mockMvc.perform(get("/tests/exception"))
.andExpect(new ResultMatcher() {
#Override
public void match(MvcResult result) throws Exception {
result.getResponse().getContentAsString().contains("global_error_test");
}
})
.andExpect(status().isNotFound());
}
I have the good status code at the end but it doesn't use my ControllerAdvice (I try with the debugger)
You can just call handler method directly
#ControllerAdvice
MyAdvice{
#ExceptionHandeler(listOfExxcetpions)
public ResponseEntity someOfMyExceptionsHandler(Exception e){
.....
}
}
and in test
MuTest{
private MyAdvice advice=new MyAdvice();
#Test
public void oneOfTests(){
Exception e=new SomeSortOfExceptionToTest();
resp=advice.someOfMyExceptionsHandler(e)
assertThat(resp).....dostuff;
}
}
If you want to test how spring integrates with your handlers - if your annotations are correct, ordering serialization etc - well that will be an integration test and you have to boot up test context - then you can throw exceptions directly from controller methods.
In my spring boot application, I have created a custom exception handler using #ControllerAdvice, and a custom exception ServerException, when I throw the custom exception, it does not get caught by my customExcpetionHandler, though I am able to check whether actually the excpetion is thrown and it is getting thrown as shown by logs.
Below is the code for my ServerException:
public class ServerException extends Exception {
/**
*
*/
private static final long serialVersionUID = <uid>;
public ServerException(String message) {
super(message);
}
}
Below is my GlobalCustomExceptionHandler class:
#ControllerAdvice
#EnableWebMvc
public class GlobalCustomExceptionHandler extends ResponseEntityExceptionHandler{
#ExceptionHandler(ServerException.class)
#ResponseStatus(HttpStatus.BAD_REQUEST)
#ResponseBody
public ModelMap handleServerException(ServerException ex) {
ModelMap modelMap = new ModelMap();
modelMap.addAttribute("status", "ERROR_400_Bad_Request");
modelMap.addAttribute("error_message", ex.getMessage());
return modelMap;
}
}
I am throwing the exception in one of the restcontroller as follows:
throw new ServerException("invalid server configs");
But I can only see the exception getting printed in log file, and not getting it as response mentioned in handleServerException() method of GlobalCustomExceptionHandler class.
What could be the reason ?
I have just reproduced Your copy-pasted piece of code with simple REST endpoint, and it works as expected:
#RestController
public class SystemController {
#GetMapping(value = "/system")
public ResponseEntity<Object> getSystem() throws ServerException {
if (true)
throw new ServerException("Checking this out");
return new ResponseEntity<>(HttpStatus.OK);
}
}
Calling http://localhost:8080/system
Results with:
{"status":"ERROR_400_Bad_Request","error_message":"Checking this out"}
I need bigger picture to help You. Paste controller that is throwing that as well as main application config class.
