SpringBoot ~ SpringBoot定時任務Quartz

SpringBoot定時任務Quartz

quartz是一個功能豐富的開源作業調度庫

1. 添加pom依賴

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-quartz</artifactId>
   </dependency>

2. 創建定時Job

   • 通過普通JavaBean創建，添加@Component註解將之註冊到容器

   /**
    * @author wsyjlly
    * @create 2019.07.17 - 14:40
    **/
   @Component
   public class ScheduleDemo2 {
       public void schedule(){
           System.out.println("ScheduleDemo2.schedule...");
       }
   }

- 通過繼承抽象類QuartzJobBean創建，該方式需要實現該類中的executeInternal方法，該方法在任務被調用時使用。

/**
 * @author wsyjlly
 * @create 2019.07.17 - 14:40
 **/
public class ScheduleDemo3 extends QuartzJobBean {
    private String name;
    public void setName(String name){
        this.name = name;
    }

    @Override
    protected void executeInternal(JobExecutionContext jobExecutionContext){
        System.out.println("ScheduleDemo3.executeInternal..."+name);
    }
}

1. 創建Quartz配置類QuartzConfig對Job進行配置

   /**
    * @author wsyjlly
    * @create 2019.07.17 - 14:47
    **/
   @Configuration
   public class QuartzConfig {
       
       @Bean
       MethodInvokingJobDetailFactoryBean jobDetail1(){
           MethodInvokingJobDetailFactoryBean bean = new MethodInvokingJobDetailFactoryBean();
           bean.setTargetBeanName("scheduleDemo2");
           bean.setTargetMethod("schedule");
           return bean;
       }
       
       @Bean
       JobDetailFactoryBean jobDetail2(){
           JobDetailFactoryBean bean = new JobDetailFactoryBean();
           bean.setJobClass(ScheduleDemo3.class);
           JobDataMap jobDataMap = new JobDataMap();
           jobDataMap.put("name","ysw");
           bean.setJobDataMap(jobDataMap);
           bean.setDurability(true);
           return bean;
       }
       
       @Bean
       SimpleTriggerFactoryBean simpleTrigger(){
           SimpleTriggerFactoryBean bean = new SimpleTriggerFactoryBean();
           bean.setJobDetail(jobDetail1().getObject());
           bean.setRepeatCount(3);
           bean.setStartDelay(1000);
           bean.setRepeatInterval(2000);
           return bean;
       }
       
       @Bean
       CronTriggerFactoryBean cronTrigger(){
           CronTriggerFactoryBean bean = new CronTriggerFactoryBean();
           bean.setJobDetail(jobDetail2().getObject());
           bean.setCronExpression("* * * * * ?");
           return bean;
       }
   
       @Bean
       SchedulerFactoryBean schedulerFactory(){
           SchedulerFactoryBean bean = new SchedulerFactoryBean();
           SimpleTrigger simpleTrigger = simpleTrigger().getObject();
           CronTrigger cronTrigger = cronTrigger().getObject();
           bean.setTriggers(simpleTrigger,cronTrigger);
           return bean;
       }
   }
