```
public void start(Promise<Void> startPromise) throws Exception {
HttpServer server = vertx.createHttpServer();
Router router = Router.router(vertx);
router.route()
.handler(event -> {
System.out.println(1);
HttpClient httpClient = vertx.createHttpClient();
HttpProxy proxy = HttpProxy.reverseProxy( httpClient).origin(80, "baidu.com");
proxy.handle(event.request());
event.addEndHandler(h -> event.next());
});
router.route().handler(e -> System.out.println(3));
server.requestHandler(router).exceptionHandler(throwable -> System.out.println(throwable.getMessage()));
server.listen(18081);
}

```


以上代码可以实现代理，并按 route 添加顺序打印出 1 , 3
