Frühling @ExceptionHandler doesnt Griff Fehler

Question

Ich habe eine Klasse wie

@RestController 
public class CustomerRestController { 

    @Autowired 
    private CustomerManagementService customerManagementService; 

    /** 
    * 
    * @return 
    */ 
    @ExceptionHandler(CustomerNotFoundException.class) 
    public ResponseEntity<ClinetErrorInformation> rulesForCustomerNotFound() { 

     ClinetErrorInformation clinetErrorInformation = new ClinetErrorInformation("Clinet was not found"); 
     return new ResponseEntity<>(clinetErrorInformation, HttpStatus.NOT_FOUND); 
    } 

    @RequestMapping(value = {"/customer/{id}"}) 
    public Customer requestCustomerById(@PathVariable String id) throws CustomerNotFoundException { 
     return customerManagementService.findCustomerById(id); 
    } 

} 

Die Ausnahme von der Klasse nicht behandelt wird:

Schwere: com.mycompany.crmproject.services.customer.CustomerNotFoundException bei ... com.mycompany.crmproject.restcontroller.CustomerRestController.requestCustomerById (CustomerRestController.java:44)

Dispatcher Servlet:

      </map> 
     </property> 

     <property name="ignoreAcceptHeader" value="false"/> 

    </bean> 

</beans> 

Was vielleicht der Grund, warum dieser Fehler nicht behandelt wird und in der Browesr kann ich nur leere Seite sehen.

Answer 1

Sind Sie sicher, dass die Ausnahme ausgelöst wird? Sieht so aus, als ob der Service null zurückgibt und das sieht man.

Answer 2

hinzufügen @ResponseBody zu Ihrer Methode Exception-Handler. Mit @RestController verwenden nur die @RequestMapping Methoden standardmäßig .

---

Vielleicht haben Sie einen anderen Ausnahme Resolver registriert. Ändern Sie die Priorität für ExceptionHandlerExceptionResolver.

Wenn Sie Annotation-Konfiguration verwenden:

@Bean 
public ExceptionHandlerExceptionResolver exceptionHandlerExceptionResolver()   
{ 
    ExceptionHandlerExceptionResolver exceptionHandlerExceptionResolver = new ExceptionHandlerExceptionResolver(); 
    exceptionHandlerExceptionResolver.setOrder(1); 
    return exceptionHandlerExceptionResolver; 
} 

Wenn Sie XML-Konfiguration verwenden:

<bean class="org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver"> 
    <property name="order" value="1"/> 
</bean>
