本文整理了Java中io.vertx.ext.web.Route.failureHandler方法的一些代码示例，展示了Route.failureHandler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。Route.failureHandler方法的具体详情如下：
包路径：io.vertx.ext.web.Route
类名称：Route
方法名：failureHandler

Route.failureHandler介绍

[英]Append a failure handler to the route failure handlers list. The router routes failures to failurehandlers depending on whether the various criteria such as method, path, etc match. When method, path, etc are the same for different routes, You should add multiple failure handlers to the same route object rather than creating two different routes objects with one failure handler for route
[中]将故障处理程序附加到路由故障处理程序列表。路由器根据方法、路径等各种条件是否匹配，将故障路由到FailureHandler。当不同路由的方法、路径等相同时，应向同一路由对象添加多个故障处理程序，而不是为路由创建两个不同的路由对象，并使用一个故障处理程序
