Router.errorHandler介绍
[英]Specify an handler to handle an error for a particular status code. You can use to manage general errors too using status code 500. The handler will be called when the context fails and other failure handlers didn't write the reply or when an exception is thrown inside an handler. You must not use RoutingContext#next() inside the error handler This does not affect the normal failure routing logic.
