Java HTTP Client Request with defined timeout

Solution 1:

If you are using Http Client version 4.3 and above you should be using this:

RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(30 * 1000).build();
HttpClient httpClient = HttpClientBuilder.create().setDefaultRequestConfig(requestConfig).build();

Solution 2:

import org.apache.http.client.HttpClient;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpConnectionParams;
import org.apache.http.params.HttpParams;

...

    // set the connection timeout value to 30 seconds (30000 milliseconds)
    final HttpParams httpParams = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(httpParams, 30000);
    client = new DefaultHttpClient(httpParams);

Solution 3:

HttpParams is deprecated in the new Apache HTTPClient library. Using the code provided by Laz leads to deprecation warnings.

I suggest to use RequestConfig instead on your HttpGet or HttpPost instance:

final RequestConfig params = RequestConfig.custom().setConnectTimeout(3000).setSocketTimeout(3000).build();
httpPost.setConfig(params);

Solution 4:

It looks like you are using the HttpClient API, which I know nothing about, but you could write something similar to this using core Java.

try {

   HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection();
   con.setRequestMethod("HEAD");
   con.setConnectTimeout(5000); //set timeout to 5 seconds
   return (con.getResponseCode() == HttpURLConnection.HTTP_OK);

} catch (java.net.SocketTimeoutException e) {
   return false;
} catch (java.io.IOException e) {
   return false;
}
