vertx 监听端口的错误怎样监听。

Question

@Override public void start() throws Exception { try{ vertx.createHttpServer() .requestHandler(req -> req.response().end("hello")) .listen(8080) .connectionHandler( r-> { System.out.println(r.remoteAddress()); }) .close( r -> { System.out.println("closed"); }); }catch (Exception e){ //e.printStackTrace(); System.out.println("eeee"); } } 我想捕获 java.net.BindException: Address already in use: bind 该怎么写。
