httpclient4的设置方式和httpclient3有所不同，代码如下：

HttpClient httpclient = new  DefaultHttpClient();
httpclient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,  Config.20000);//连接时间20s
httpclient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,  60000);//数据传输时间60s

不设置的后果就是一旦对方服务器出现无响应的情况，如果有返回（404 50x）错误还好，没有返回了你就哭了，java线程会一直等待！！

以下是网上的：

DefaultHttpClient:
请求超时
httpclient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 60000); 
读取超时
httpclient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 60000);

HttpClient
HttpClient httpClient=new HttpClient(); 
链接超时
httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(60000);  
读取超时
httpClient.getHttpConnectionManager().getParams().setSoTimeout(60000)
