我们都知道任务调度可以用Quartz,但对于简单的定时任务,可以直接用Spring内置的Schedule来实现.可以由两种方式,注释+XML配置 注解方式: 注解也要先在sping.xml配置文件中配置自动发现 XML中引入命名空间: xmlns:task="http://www.springframework.org/schema/task" http://www.springframework.org/schema/task http://www.springframework.o…

在spring 中的新引入的task 命名空间.可以部分取代 quartz 功能,配置和API更加简单,并且支持注解方式. 第一步: 在Spring的相关配置文件中(applicationContext.xml或者是{project_name}_servelt.xml或者是独立的配置文件如XXX_quartz.xml)中配置并开启Spring Schedule Task.注意其中高亮的部分是必须的. <?xml version="1.0" encoding="UTF-8…

现在做的项目都有用到Schedule,现在用一点时间来总结. 一.首先要到Nuget中下载Quartz.net. 二.下载下来了,你需要对它进行配置,使它能给你正常的使用. 三.在Global.asax中进行quartz进行初始化. 四.quartz_jobs_Schedule.xml 可以在这边个格式是这样的. <schedule> <name>DownloadDso</name> <job-type>LocalKwmsOne.Schedule.Jobs.…

:nRF51822虽然是一个小型的单片机,但是能真正达到任意调用其官方驱动以及BLE协议栈的人还是奇缺的.据我所见,大都拿官方给的一个冗长的蓝牙低功耗心率计工程改的.之前我对于这个工程进行log跟踪,虽然理清了其大致流程,但还是达不到任意修改甚至是构建自己的框架的程度.本文接上一篇,继续理解library中的调度处理和定时器部分. 1.Schedule handling library 调度程序主要负责从中断上下文向main函数上下文传送执行命令. 在main函数中: 1.为每种期望的事件定义句…
