java.lang.IllegalStateException: Connection pool shut down
提问by User3
I am trying to post data to a REST service using Http and I have configured my client as follows:
我正在尝试使用 Http 将数据发布到 REST 服务，并且我已将我的客户端配置如下：
PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();
cm.setMaxTotal(60);
cm.setDefaultMaxPerRoute(60);
CloseableHttpClient httpclient = HttpClients.custom().setConnectionManager(cm).build();
HttpPost httpPost = new HttpPost(url);
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
CloseableHttpResponse response = null;
Now I have an executor service which is responsible for calling the actual posting, I hand over the above params to Executor service as follows:
现在我有一个 executor 服务负责调用实际发布，我将上述参数交给 Executor 服务，如下所示：
executor.execute(new LocalThreadPoolExecutor(line, client, httpPost,response ));
line is the JSON payload I am trying to send across.
line 是我尝试发送的 JSON 有效负载。
Now my method in executor service looks like:
现在我在执行程序服务中的方法如下所示：
private void postData(String data, CloseableHttpClient client, HttpPost httpPost,
CloseableHttpResponse response) throws Exception {
System.out.println("Post hit");
StringEntity entity = new StringEntity(data);
httpPost.setEntity(entity);
response = client.execute(httpPost);
int code = response.getStatusLine().getStatusCode();
System.out.println("Stat" + code);
logger.info("Response Code: " + code);
String temp;
String builder = "Response: ";
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
while ((temp = bufferedReader.readLine()) != null) {
builder = builder + (temp + "\n");
}
System.out.println(builder);
//logger.info(payload);
client.close();
}
And and I am getting an exception at response = client.execute(httpPost);
而且我在 response = client.execute(httpPost);
Which is:

I know where the problem is, however I am unable to determine how to solve it!
我知道问题出在哪里，但我无法确定如何解决！
Any help would be highly appreciated!
任何帮助将不胜感激！

client.close();will close the connection of CloseableHttpClient. If you access the execute method on the second time after the connection gets closed, This error will throw.
客户端关闭（）；将关闭 CloseableHttpClient 的连接。如果在连接关闭后第二次访问 execute 方法，则会抛出此错误。
