Hi,i use PoolingHttpClientConnectionManager with httpclient4.4 .
I see the code in MainClientExec.java,but i can't understand .
The respone entity is always not null and is stream,so the releaseConnection
method cant be invoked always.
final HttpEntity entity = response.getEntity();
if (entity == null || !entity.isStreaming()) {
// connection not needed and (assumed to be) in re-usable state
connHolder.releaseConnection();
return new HttpResponseProxy(response, null);
} else {
return new HttpResponseProxy(response, connHolder);
}
I have see the link
http://hc.apache.org/httpcomponents-client-4.3.x/tutorial/html/advanced.html#stateful_conn
In my program ,I did not visit https website.
My code
for (int i=0;i<2;i++){
new Thread(new Runnable() {
public void run() {
SendFile.test("http://tool.chinaz.com/";,
"start");
try {
.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
}
public static void test(String url, String functionname) {
HttpPost post = new HttpPost(url);
CloseableHttpClient client = httpClient;
CloseableHttpResponse r = null;
try {
r = client.execute(post, HttpClientContext.create());
HttpEntity entity = r.getEntity();
entity.getContent();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
}
}
private static PoolingHttpClientConnectionManager cm = new
PoolingHttpClientConnectionManager();
private static CloseableHttpClient httpClient;
static {
cm.setMaxTotal(200);
cm.setDefaultMaxPerRoute(2);
RequestConfig defaultRequestConfig = RequestConfig.custom()
.setSocketTimeout(10000).setConnectTimeout(10000)
.setConnectionRequestTimeout(50000).build();
httpClient = HttpClients.custom()
.setDefaultRequestConfig(defaultRequestConfig)
.setConnectionManager(cm).build();
}
The log output is here .

Any help in this issue would be much appreciated.
