Getting UndeclaredThrowableException instead of my own exception

I have the following code

public Object handlePermission(ProceedingJoinPoint joinPoint, RequirePermission permission) throws AccessException, Throwable {
    System.out.println("Permission = " + permission.value());
    if (user.hasPermission(permission.value())) {
        System.out.println("Permis开发者_如何学Gosion granted ");
        return joinPoint.proceed();
    } else {
        System.out.println("No Permission");
        throw new AccessException("Current user does not have required permission");
    }

}

When I use a user that does not have permissions, I get java.lang.reflect.UndeclaredThrowableException instead of AccessException.

AccessException is a checked exception, but it was thrown from the method that doesn't declare it in its throws clause (actually - from the aspect intercepting that method). It's an abnormal condition in Java, so your exception is wrapped with UndeclaredThrowableException, which is unchecked.

To get your exception as is, you can either declare it in the throws clause of the method being intercepted by your aspect, or use another unchecked exception (i.e. a subclass of RuntimeException) instead of AccessException.
