HttpClient库设置超时

3.x
HttpClient client = new HttpClient();
client.setConnectionTimeout(30000); 
client.setTimeout(30000);

HttpClient httpClient= new HttpClient(); 
httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(5000);

4.1
HttpClient httpClient=newDefaultHttpClient();
httpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,2000);//连接时间
httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,2000);//数据传输时间

4.3
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpGet httpGet=newHttpGet("http://www.baidu.com");//HTTP Get请求(POST雷同)
RequestConfig requestCOnfig= RequestConfig.custom().setSocketTimeout(2000).setConnectTimeout(2000).build();//设置请求和传输超时时间
httpGet.setConfig(requestConfig);
httpClient.execute(httpGet);//执行请求

CloseableHttpClient httpclient = HttpClients.createDefault();  

HttpGet httpGet = new HttpGet("http://stackoverflow.com/");  

RequestConfig requestCOnfig= RequestConfig.custom()  

        .setConnectTimeout(5000).setConnectionRequestTimeout(1000)  

        .setSocketTimeout(5000).build();  

httpGet.setConfig(requestConfig);  

CloseableHttpResponse respOnse= httpclient.execute(httpGet);  

System.out.println("得到的结果:" + response.getStatusLine());//得到请求结果 

HttpEntity entity = response.getEntity();//得到请求回来的数据

RequestConfig requestCOnfig= RequestConfig.custom()  
                    .setConnectionRequestTimeout(config.connReqTimeout)   //从连接池中获取连接的超时时间 
                            //与服务器连接超时时间：httpclient会创建一个异步线程用以创建socket连接，此处设置该socket的连接超时时间 
                    .setConnectTimeout(config.connTimeout)  
                    .setSocketTimeout(config.socketTimeout)               //socket读数据超时时间：从服务器获取响应数据的超时时间 
                    .build();  
            httpClient = HttpClientBuilder.create()  
                    .setMaxConnTotal(config.maxConnTotal)                   //连接池中最大连接数 
                            /** 
 * 分配给同一个route(路由)最大的并发连接数。 
 * route：运行环境机器 到 目标机器的一条线路。 
 * 举例来说，我们使用HttpClient的实现来分别请求 www.baidu.com 的资源和 www.bing.com 的资源那么他就会产生两个route。 
 */  
                    .setMaxConnPerRoute(config.maxConnPerRoute)  
                    .setDefaultRequestConfig(requestConfig)  
                    .build();
