@ControllerAdvice exception handler method not get called

Question

I am working on sample demo application for Exception Handling in Spring MVC.I am trying Exception Handling With @ControllerAdvice

I followed steps as describe in this link.

But when i run my application i get the following error

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is com.test.core.ApplicationException

For more details following are the classes I am working on

ApplicationException.java

public class ApplicationException extends RuntimeException{


/**
 * 
 */
private static final long serialVersionUID = -9061684361606685158L;
private ErrorStatus errorStatus;
private int msgNumber;
private Object []args;

public ApplicationException(){}

public ApplicationException(ErrorStatus errorStatus, int msgNumber,
        Object[] args) {
    this.errorStatus = errorStatus;
    this.msgNumber = msgNumber;
    this.args = args;
  }
    //getter setters
}

Controller class

ApplicationExceptionController.java

 @Controller
@RequestMapping("/exception")
public class ApplicationExceptionController {

@RequestMapping(value="/error",method=RequestMethod.GET)
@ResponseBody
public void helloException() 
{
    throw new ApplicationException(ErrorStatus.NotFound,1,new Object[]{"Website"});

  //here ErrorStatus is a enum class
}  
}

And here is the GlobalExceptionHandler class

GlobalExceptionHandler.java

@ControllerAdvice
public class GlobalExceptionHandler {

@ExceptionHandler
public void notFount(){
    System.out.println("----------CaughtApplicationException-----------");
}
}

dispatcher-servlet.xml

But I get the following Exception

I go through @ControllerAdvice exception handler method are not get called this link but still stuck with the same problem Please help me to get the solution.I am not getting the actual cause for this exception.

Answer 1

You are missing @EnableWebMvc annotation in your Exception handler. Your Exception handler should be like this.

@EnableWebMvc
@ControllerAdvice
public class GlobalExceptionHandler {

    @ExceptionHandler({ApplicationException.class})
    public void notFount(){
        System.out.println("----------CaughtApplicationException-----------");
    }

    @ExceptionHandler({Exception.class})
    public void notFountGlobal(){
        System.out.println("----------CaughtApplicationException-----------");
    }

}

Also you need to tell exception handler method which exception you want to catch in which method. At last you can specify a method which can caught all other exception passing it Exception.class. The code snippet you post work for me. Hopefully it will resolve your problem.
