服务宕机重启后quartz没有执行之前设置的定时任务

问题：服务宕机重启后quartz没有执行之前设置的定时任务。

原因：没有配置jobStore，设置的定时不会写入到qrtz开头的表中。重启服务quartz无法自动拾取之前设置的定时任务。

有jobStore的配置：

#  quartz:
#      #相关属性配置
#      properties:
#        org:
#          quartz:
#            scheduler:
#              #quartzScheduler
#              instanceName: quartzScheduler
#              instanceId: AUTO
#            jobStore:
#              class: org.quartz.impl.jdbcjobstore.JobStoreTX
#              driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#              tablePrefix: QRTZ_
#              #isClustered: false
#              isClustered: true
#              clusterCheckinInterval: 10000
#              #useProperties: false
#              useProperties: true
#              dataSource: quartzDs
#            threadPool:
#              class: org.quartz.simpl.SimpleThreadPool
#              threadCount: 10
#              threadPriority: 5
#              threadsInheritContextClassLoaderOfInitializingThread: true
#      #数据库方式
#      job-store-type: JDBC
#      #初始化表结构
#      jdbc:
#        initialize-schema: NEVER

 

没有jobStore的配置：

quartz:
    #相关属性配置
    properties:
      org:
        quartz:
          scheduler:
            instanceName: quartzScheduler
            instanceId: AUTO
          threadPool:
            class: org.quartz.simpl.SimpleThreadPool
            threadCount: 10
            threadPriority: 5
            threadsInheritContextClassLoaderOfInitializingThread: true

 

没有配置jobStore的配置的，需要在服务重启中加载cron列表并放入定时器scheduler中。而配置jobStore的quartz会自动加载qrtz中之前设置的定时任务。

//        List<QuartzJob> jobs = jobMapper.listJob("");
