java - httpclientbuilder - httpClient.getConnectionManager() está en desuso. ¿Qué debería usarse en su lugar?

import org apache http httpentity maven

Question

He heredado el codigo

import org.apache.http.client.HttpClient;
...
HttpClient httpclient = createHttpClientOrProxy();
try {
HttpPost postRequest = postRequest(data, url);
body = readResponseIntoBody(body, httpclient, postRequest);
} catch( IOException ioe ) {
throw new RuntimeException("Cannot post/read", ioe);
} finally {
httpclient.getConnectionManager().shutdown(); // ** Deprecated
}
private HttpClient createHttpClientOrProxy() {
HttpClient httpclient = new DefaultHttpClient();
/*
* Set an HTTP proxy if it is specified in system properties.
*
* http://docs.oracle.com/javase/6/docs/technotes/guides/net/proxies.html
* http://hc.apache.org/httpcomponents-client-ga/httpclient/examples/org/apache/http/examples/client/ClientExecuteProxy.java
*/
if( isSet(System.getProperty("http.proxyHost")) ) {
log.warn("http.proxyHost = " + System.getProperty("http.proxyHost") );
log.warn("http.proxyPort = " + System.getProperty("http.proxyPort"));
int port = 80;
if( isSet(System.getProperty("http.proxyPort")) ) {
port = Integer.parseInt(System.getProperty("http.proxyPort"));
}
HttpHost proxy = new HttpHost(System.getProperty("http.proxyHost"), port, "http");
// @Deprecated methods here... getParams() and ConnRoutePNames
httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
}
return httpclient;
}

getConnectionManager() lee "

@Deprecated
ClientConnectionManager getConnectionManager()
Deprecated. (4.3) use HttpClientBuilder.
Obtains the connection manager used by this client.

Los documentos para HttpClientBuilder parecen escasos y simplemente dicen:

Builder for CloseableHttpClient instances.

Sin embargo, si sustituyo HttpClient por CloseableHttpClient el método todavía parece @Deprecated .

¿Cómo puedo usar un método no en desuso?

Answer 1

En lugar de crear una nueva instancia de HttpClient, use el Generador. Usted obtendría un CloseableHttpClient.

por ejemplo, uso:

CloseableHttpClient httpClient = HttpClientBuilder.create().setProxy(proxy).build()

En lugar de usar getConnectionManager (). Shutdown (), use el método close () en lugar de CloseableHttpClient.
