HttpAsyncClient异步报错Request cannot be executed; I/O reactor status: INACTIVE

You need to start the async client before using it
try (CloseableHttpAsyncClient httpclient = HttpAsyncClients.createDefault()) {
            httpclient.start();

}

Request cannot be executed; I/O reactor status: INACTIVE

    CloseableHttpAsyncClient asyncHttpClient= HttpAsyncClients.createDefault();
    asyncHttpClient.start();

异步httpAsyncclient与同步不同，需要在回调之前调用start()方法
