Based on this thread Registering a custom ResourceMethodInvocationHandler in Jersey , I was able to intercept Jersey resource method calls after unmarshalling the JSON.
But how do I throw a custom exception based on some logic (Eg: Forbidden exception) in the MyInvocationHandler before invoking the method. When I do that, I am getting 500 error javax.servlet.ServletException
:
public class MyIncovationHandler implements InvocationHandler {
@Override
public Object invoke(Object obj, Method method, Object[] args)
throws Throwable {
if(!verifyAccess(args)) {
throw new ForbiddenException();
}
Object result = method.invoke(obj, args);
return result;
}
}
Getting below error with 500 error code instead of 403 forbidden
javax.servlet.ServletException: javax.ws.rs.ProcessingException: javax.ws.rs.ProcessingException: javax.ws.rs.ProcessingException: javax.ws.rs.ForbiddenException: HTTP 403 Forbidden
