• Quartz+Spring 实现定时任务的 管理和监控


     0,监控的意义

    (1)能够查看有多少定时任务,用的什么执行策略,便于管理

    (2)能够通过界面操作停止或启动某个定时任务,便于管理

    (3)能够通过界面操作改变某个定时任务的执行策略,便于管理

    1,pom.xml 文件添加jar

     1 <!-- quartz监控 -->
     2 <dependency>
     3     <groupId>org.quartz-scheduler</groupId>
     4     <artifactId>quartz</artifactId>
     5     <version>2.2.1</version>
     6 </dependency>
     7 <dependency>
     8     <groupId>org.quartz-scheduler</groupId>
     9     <artifactId>quartz-jobs</artifactId>
    10     <version>2.2.1</version>
    11 </dependency>

    2,applicationContext.xml添加

    <bean id="schedulerFactoryBean"
    class="org.springframework.scheduling.quartz.SchedulerFactoryBean" />

    或者SpringBoot中

    1 @Bean
    2 public SchedulerFactoryBean  schedulerFactoryBean() {
    3 
    4   return new SchedulerFactoryBean();
    5 }

    3,Taskcontroller层
