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
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

2.3 添加 quartz 配置文件（springms-simple-quartz-cluster/src/main/resources/quartz.properties）
org.quartz.scheduler.instanceName = quartzScheduler

org.quartz.threadPool.threadCount = 10
org.quartz.threadPool.threadPriority = 5

2.4 添加 quartz 任务配置文件（springms-simple-quartz-cluster/src/main/resources/quartz.xml）

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

@SpringBootApplication
@ImportResource("quartz.xml")
public class SimpleQuartzClusterApplication {
private static final Logger Logger = LoggerFactory.getLogger(SimpleQuartzClusterApplication.class);

}
}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；
