exception

问题 I have an aspect class as below - public class TestAspect { @AfterThrowing(pointcut = "execution(* *(..)) ", throwing = "testException") public void afterThrowAdvice(TestException testException) throws Exception { } } Now anytime any class throws TestException, TestAspect's afterThrowAdvice method is getting called. From Unit tests as well without using any spring configuration xmls, running as a plain junit test. How do I mock to not do anything when that method is called? I tried in my unit

问题 I've found a contradiction I could not understand. Exception::getCode() has this definition: final public Exception::getCode ( void ) : mixed with description: Returns the exception code as integer in Exception but possibly as other type in Exception descendants (for example as string in PDOException) but the Exception class implements Throwable interface that defines: abstract public getCode ( void ) : int So how for an example PDOException as a descendant of Exception could return string

问题 I have created custom exception in python 3 and the over all code works just fine. But there is one thing I am not able to wrap my head around is that why do I need to send my message to the Exception class's __init__() and how does it convert the Custom exception into that string message when I try to print the exception since the code in the Exception or even the BaseException does not do much. Not quite able to understand why call the super().__init__() from custom exception? 回答1: This is

问题 I'm tryign to have twisted 19.7.0 running on macOS Catalina 10.15.1 with Python 3.7.5 . I choose the chat sample to verify if it works (see source chat.py in https://twistedmatrix.com/documents/current/core/howto/servers.html).
