我想對(duì)我的云中的許多服務(wù)器進(jìn)行BIT（內(nèi)置測(cè)試）。我需要大超時(shí)失敗的請(qǐng)求。我應(yīng)該如何用Java做到這一點(diǎn)？嘗試以下操作似乎無(wú)效。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(""); }}-編輯：澄清正在使用的庫(kù)-我正在使用來(lái)自Apache的httpclient，這是相關(guān)的pom.xml部分 <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.0.1</version> <type>jar</type> </dependency>

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

看來(lái)您正在使用HttpClient API，對(duì)此我一無(wú)所知，但是您可以使用核心Java編寫(xiě)類似的內(nèi)容。
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;
}
