If we want to centralize the exception-handling logic to one class that is capable of handling exceptions thrown from any handler class/controller class – then we can use@ControllerAdviceannotation. By default, the methods in an@ControllerAdviceapply globally to all controllers.We can create a cla...
1、表示标有这个注解的类是一个Controller。它有一个默认行为:被注解的类会作用到所有已知的Controller上。 2、它通常会和 @ExceptionHandler @InitBinder @ModelAttribute 等注解一起使用 /*** Indicates the annotated class assists a "Controller". * * Serves as a specialization of {@linkComponent @Compone...

可以使用!thread扩展以及dds、dps 和 dqs(显示字词和符号)命令完成更多分析。 当 WinDbg 报告“可能由:ntkrnlmp.exe 引起”时,此技术是合理的。 如果出现异常代码 0x80000003,则表示命中了硬编码断点或断言,但系统是使用/NODEBUG开关启动的。 此问题应该不会经常发生。 如果重复发生,请确保内核调试器...
I override the OnException() method and replace the default "ITraceWriter" service with our NLogger class instance in the controller’s service container, same as we have done in Action logging in above section. Now the GetTraceWriter() method will return our instance (instance NLogger class...
