本文整理了Java中io.vertx.ext.web.Router.errorHandler方法的一些代码示例，展示了Router.errorHandler的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Router.errorHandler方法的具体详情如下：
包路径：io.vertx.ext.web.Router
类名称：Router
方法名：errorHandler
[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.
