Monitor对象存在于每个Java对象的对象头Mark Word中(存储的指针的指向),Synchronized锁便是通过这种方式获取锁的。 对象内存布局 1. 对象头(Header) 比如hash码,对象所属的年代,对象锁,锁状态标志,偏向锁(线程)ID,偏向时间,数组长度(数组对象)等。 Java对象头一般占有2个机器码(在32位虚拟机中,1个机器码等于4字...
3.返回、登录信息、消息通知、首页推送 如果接口中,每个步骤都是同步处理,总共就需要 1700s = 300ms + 100ms + 300ms + 1000ms 现在可以将步骤 2.1、 2.2、2.3, 开启异步线程,同时处理,(暂不考虑开启线程的耗时) 也就是意味步骤 2.1、 2.2、2.3,任务总耗时就是步骤2.3的耗时1000ms 再加上1步骤的验证耗时...

要使用Future<T>获取AsyncResult<T>作为返回值,可以按照以下步骤进行操作: 首先,确保你的开发环境支持异步操作和Future对象。常见的编程语言和框架如Java、Python、C++、JavaScript等都提供了相关的支持。 在调用异步方法时,可以使用AsyncResult<T>作为返回值类型。AsyncResult<T>是一种表示异步操作结果的泛型类,它...
