SpringCloud(第 010 篇)简单 Quartz-Cluster 微服务,支持集群分布式,并支持动态修改 Quartz 任务的 cronExpression 执行时间

-

一、大致介绍

1、根据上一章节的单台测试,本章节修改 Quartz 了支持分布式,因为这是更多的企业开发场景所需要的开发模式;
2、而且在定时任务执行的过程中,通过修改 Quartz 触发器表的 cronExpression 表达式值,从而达到动态修改定时任务的执行时间;

3、注意:配置文件中的 mysql 数据库链接配置大家就各自配置自己的哈;

二、实现步骤

2.1 添加 maven 引用包

    // ② concurrent:对于相同的JobDetail,当指定多个Trigger时, 很可能第一个job完成之前,
    // 第二个job就开始了。指定concurrent设为false,多个job不会并发运行,第二个job将不会在第一个job完成之前开始。
    // ③ cronExpression:0/10 * * * * ?表示每10秒执行一次,具体可参考附表。
    // ④ triggers:通过再添加其他的ref元素可在list中放置多个触发器。 scheduleInfoAction中的simpleJobTest()方法

2.11 添加 Quartz-Cluster 启动类(springms-simple-quartz-cluster/src/main/java/com/springms/cloud/SimpleQuartzClusterApplication.java)

三、测试

/****************************************************************************************
 一、简单 Quartz-Cluster 微服务,支持集群分布式,并支持动态修改 Quartz 任务的 cronExpression 执行时间:

 1、添加 Quartz 相关配置文件;
 2、启动 springms-simple-quartz-cluster 模块服务,启动1个端口(8395);
 3、然后查看日志, ScheduleTask 类的 sayHello 方法被有规律的调用,并打印日志出来;

 4、启动 springms-simple-quartz-cluster 模块服务,再启动2个端口(8396、8397);
 5、然后看到 3 台服务器只有 1 台服务器调用了 sayHello 方法,因此 Quartz 的集群分布式也算是部署成功了;
 ****************************************************************************************/

/****************************************************************************************
 二、简单 Quartz-Cluster 微服务,支持集群分布式,并支持动态修改 Quartz 任务的 cronExpression 执行时间(动态修改定时任务的 cronExpression 时间表达式):

 1、添加 Quartz 相关配置文件;
 2、启动 springms-simple-quartz-cluster 模块服务,启动3个端口(8395、8396、8397);
 3、然后看到 3 台服务器只有 1 台服务器调用了 sayHello 方法打印了日志,因此 Quartz 的集群分布式也算是部署成功了;
 4、然后新起网页输入 http://localhost:8395/modify/5 修改定时任务的触发时间;
 5、再等一会儿就看到 3 台服务器只有 1 台服务器每隔 5 秒调用一次 sayHello 方法,因此修改定时任务的克隆表达式也算是成功了;
 ****************************************************************************************/

/****************************************************************************************
 三、简单 Quartz-Cluster 微服务,支持集群分布式,并支持动态修改 Quartz 任务的 cronExpression 执行时间(动态删除其中 1 台活跃 Quartz 服务器,然后剩下的其中 1 台自动接替):

 1、添加 Quartz 相关配置文件;
 2、启动 springms-simple-quartz-cluster 模块服务,启动3个端口(8395、8396、8397);
 3、然后看到 3 台服务器只有 1 台服务器调用了 sayHello 方法打印了日志,因此 Quartz 的集群分布式也算是部署成功了;
 4、然后关闭 1 台活跃 Quartz 服务器;
 5、再等一会儿就看到 2 台服务器中的 1 台服务器每隔一定的时间调用一次 sayHello 方法;
