Java HTTP Client Request with defined timeout

Question

I would like to make BIT (Built in tests) to a number of server in my cloud. I need the request to fail on large timeout.

How should I do this with java?

Trying something like the below does not seem to work.

public class TestNodeAliveness {
 public static NodeStatus nodeBIT(String elasticIP) throws ClientProtocolException, IOException {
  HttpClient client = new DefaultHttpClient();
  client.getParams().setIntParameter("http.connection.timeout", 1);

  HttpUriRequest request = new HttpGet("http://192.168.20.43");
  HttpResponse response = client.execute(request);

  System.out.println(response.toString());
  return null;
 }


 public static void main(String[] args) throws ClientProtocolException, IOException {
  nodeBIT("");
 }
}

-- EDIT: Clarify what library is being used --

I'm using httpclient from apache, here is the relevant pom.xml section

 <dependency>
   <groupId>org.apache.httpcomponents</groupId>
   <artifactId>httpclient</artifactId>
   <version>4.0.1</version>
   <type>jar</type>
 </dependency>

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();
