apache http调用设置超时时间

//设置请求超时时间
RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(2000)
.setConnectionRequestTimeout(2000)
.setSocketTimeout(2000)
.build();
说明
ConnectionRequestTimeout
httpclient使用连接池来管理连接,这个时间就是从连接池获取连接的超时时间,可以想象下数据库连接池
ConnectTimeout
连接建立时间,三次握手完成时间
SocketTimeout
数据传输过程中数据包之间间隔的最大时间
