包路径：io.vertx.ext.web.Router
类名称：Router
方法名：exceptionHandler

Router.exceptionHandler介绍

[英]Specify a handler for any unhandled exceptions on this router. The handler will be called for exceptions thrown from handlers. This does not affect the normal failure routing logic.
[中]为此路由器上任何未处理的异常指定处理程序。对于处理程序引发的异常，将调用该处理程序。这不会影响正常的故障路由逻辑。
