摘要:如果服务器证书这两者不合法而我们又必须让其校验通过,则可以自己实现。这个属性是新加的属性,因为目前版本是可以共享连接池的。请求获取数据的超时时间,单位毫秒。如果访问一个接口,多少时间内无法返回数据,就直接放弃此次调用。

摘要:此时我想到了福尔摩斯说过的一句话当你排除掉各种不可能出现的情况之后,剩下的情况无论多么难以置信,都是真相。福尔摩斯冷静下来想一想,这个线程,有可能静悄悄地退出了吗,没留下半点异常日志从理论上来说,不可能。配置建议最后,附上一份配置建议。 1、事发 我们有个视频处理程序,基于 SpringBoot,会启动几个线程来跑。要退出程序时,会发送一个信号给程序,每个线程收到信号后会平滑退出,等全...
