  • Quartz线程并行串行处理至今没搞明白的博客CSDN博客

    Quartz定时任务默认都是并发执行的,不会等待上一次任务执行完毕,只要间隔时间到就会执行, 如果定时任执行太长,会长时间占用资源,导致其它任务堵塞。并行和串行含义Quartz定时任务的执行策略有并行(无状态)和串行(有状态)之分。在实际应用中需要实现Job 接口以定义自己的任务。在spring boot中使用quartz实现作业调度的功能,简单易用。什么是Quartz?Quartz是Java领域最著名的、功能丰富的、开放源码的作业调度工具,几乎可以在所有的Java应用程序中集成——从小的单机应用到大的电子商务系统。 Quartz可以用来执行Java使用quartz实现作业调度在路上的学习者CSDN博客 是一套很好的任务调度框架。 下面介绍如何使用: 在项目Nuget包管理器中搜索:quartz 安装后会添加如下dll: 简单场景 先定义一个Job,需要实现IJob接口: 启动 使用 从未被超越 博客园
