spring配置类

quartz job类
package test.daemon.clusterquartz.quartz; import java.util.date; import org.quartz.disallowconcurrentexecution; import org.quartz.jobexecutioncontext; import org.quartz.jobexecutionexception; import org.quartz.persistjobdataafterexecution; import org.springframework.scheduling.quartz.quartzjobbean; @persistjobdataafterexecution @disallowconcurrentexecution public class quartzjob extends quartzjobbean { @override protected void executeinternal(jobexecutioncontext context) throws jobexecutionexception { // todo auto-generated method stub system.out.println("\nquartz job " + new date()); } }
spring boot启动类
package test.daemon.clusterquartz; import org.springframework.boot.springapplication; import org.springframework.boot.autoconfigure.springbootapplication; @springbootapplication public class cluster { public static void main(string[] args) throws exception { springapplication.run(cluster.class, args); } }
数据库sql
可以在quartz的lib中找到适当的数据库生成文件来创建jdbc job store所需要的表。这些表用于quartz在集群环境中的调度。
一些解释
把项目复制一份,然后改掉spring server的启动端口,启动多个项目,可以观察到只有一个项目的quartz在运行。如果当前运行quartz的服务器挂掉,另一台会跟进执行相同的quartz任务。
有待思考的部分
在quartz集群环境中,时间的同步是一个重要问题,有时间需要去看一下怎么进行时间同步来确保集群的正确性。
