如何在一段时间后使 HTTP 连接超时/断开连接?

I am new in Apache HttpClient, I used the following code to get the HTTP connection timeout (disconnected) after certain time interval:

PostMethod method = new PostMethod(authURL);
HttpClient client = new HttpClient();
HttpClientParams params= new HttpClientParams();
params.setParameter(params.CONNECTION_MANAGER_TIMEOUT, 10); //10 Nano second
client.executeMethod(method);

但它等待超过一分钟而没有任何希望超时/断开连接?问题可能出在哪里?

  client.getHttpConnectionManager().
        getParams().setConnectionTimeout(5000);
  client.getHttpConnectionManager().
        getParams().setSoTimeout(5000);
