Spring + HttpClient配置多线程

矫情吗；* 2022-05-21 02:21 87阅读 0赞

HttpClient通过MultiThreadedHttpConnectionManager实现多线程通讯

HttpConnectionManagerParams设置connectionTimeout链接超时，soTimeout读取数据超时，maxTotalConnections，defaultMaxConnectionsPerHost等等参数

MultiThreadedHttpConnectionManager多线程中属性params是HttpConnectionManagerParams
