使用Vertx实现多个并发连接

Vertx vertx = Vertx.vertx();

vertx.createNetServer().connectHandler(socket -> {
    // 处理连接逻辑
}).listen(8888);

socket.handler(buffer -> {
    // 处理请求数据
    String request = buffer.toString();
    
    // 处理响应数据
    String response = "Hello, " + request;
    socket.write(response);
});

vertx.createNetClient().connect(8888, "localhost", res -> {
    if (res.succeeded()) {
        NetSocket socket = res.result();
        // 发送请求数据
        socket.write("World");
        
        // 处理响应数据
        socket.handler(buffer -> {
            String response = buffer.toString();
            System.out.println("Received response: " + response);
        });
    } else {
        System.out.println("Failed to connect: " + res.cause());
    }
});
