Java HTTP客户端请求设置超时

Question

我想设置请求的超时时间。这是代码，到目前为止我已经知道了

final HttpClient httpclient = HttpClients.createDefault();
final HttpPost httppost = new HttpPost(address);
httppost.setHeader("Accept", "text/xml");
httppost.setHeader("Content-type", "application/xml; charset=UTF-8");
httppost.setEntity(new StringEntity(body));
final HttpResponse response = httpclient.execute(httppost);
final HttpEntity entity = response.getEntity();

我尝试过（不起作用，持续加载，忽略超时）

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

（这一个抛出^{）

httpclient = HttpClients.createDefault();
httpclient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 3000);
httpclient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 6000);

有没有其他方法来设定时间？我真的不需要响应，所以像异步请求这样的东西也可以完成这项工作

Apache的HttpClient有两个独立的超时：一个是等待多长时间建立TCP连接的超时，另一个是等待后续数据字节的超时

^{}用于建立TCP连接，而^{}用于等待后续字节的数据

// Creating default HttpClient
HttpClient httpClient = new DefaultHttpClient();
final HttpParams httpParams = httpClient.getParams();

// Setting timeouts
HttpConnectionParams.setConnectionTimeout(httpParams, 5000);
HttpConnectionParams.setSoTimeout(httpParams, 30000);

// Rest of your code
final HttpPost httppost = new HttpPost(address);
httppost.setHeader("Accept", "text/xml");
httppost.setHeader("Content-type", "application/xml; charset=UTF-8");
httppost.setEntity(new StringEntity(body));
final HttpResponse response = httpclient.execute(httppost);
final HttpEntity entity = response.getEntity();
