创建httpClient时，设置timeout时间

1. //private static HttpClient httpClient = HttpClientBuilder.create().build();  

2. private static CloseableHttpClient httpClient;// = HttpClientBuilder.create().build(); //no timeout handling...  

3.   

4. static {  

5.    RequestConfig.Builder requestConfigBuilder = RequestConfig.custom();  

6.    //客户端和服务器建立连接的timeout  

7.    requestConfigBuilder.setConnectTimeout(30000);  

8.    //从连接池获取连接的timeout  

9.    requestConfigBuilder.setConnectionRequestTimeout(30000);  

10.    //连接建立后，request没有回应的timeout  

11.    requestConfigBuilder.setSocketTimeout(30000);  

12.   

13.    HttpClientBuilder clientBuilder = HttpClientBuilder.create();  

14.    clientBuilder.setDefaultRequestConfig(requestConfigBuilder.build());  

15.    clientBuilder.setDefaultSocketConfig(SocketConfig.custom().setSoTimeout(30000).build()); //连接建立后，request没有回应的timeout  

16.    clientBuilder.setKeepAliveStrategy(new DefaultConnectionKeepAliveStrategy());  

17.    httpClient = clientBuilder.build();
