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

Route.handler介绍

[英]Append a request handler to the route handlers list. The router routes requests to handlers 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 handlers to the same route object rather than creating two different routes objects with one handler for route
[中]将请求处理程序追加到路由处理程序列表。路由器根据方法、路径等各种条件是否匹配，将请求路由到处理程序。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处理程序，而不是使用一个处理程序为路由创建两个不同的路由对象

@Override
 public void start() throws Exception {

  Router router = Router.router(vertx);

  router.route().handler(routingContext -> {
   routingContext.response().putHeader("content-type", "text/html").end("Hello World!");
  });

  vertx.createHttpServer().requestHandler(router).listen(8080);
 }
}
