关于springboot集成quartz完成自动调度

一、添加依赖

<!--quartz定时调度依赖-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
</dependency>

二、创建任务类，继承QuartzJobBean实现executeInternal（调用所需实现的方法）

public class QuartzJob1 extends QuartzJobBean {

    @Override
    protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        System.out.println("QuartzJob1----" + sdf.format(new Date()));
    }

}

三、创建QuartzConfig，接着定义JobDetail，JobDetail由JobBuilder构建，同时关联了任务。

@Configuration
public class QuartzConfig {

    @Bean
    public JobDetail jobDetail1(){
        return JobBuilder.newJob(QuartzJob1.class).storeDurably().build();
    }
    
}

四、定义定时调度Trigger，简单实现类SimpleScheduleBuilder用于构建Scheduler，TriggerBuilder则用于构建Trigger，

@Configuration
public class QuartzConfig {

    @Bean
    public JobDetail jobDetail1(){
        return JobBuilder.newJob(QuartzJob1.class).storeDurably().build();
    }

    @Bean
    public Trigger trigger1(){
        SimpleScheduleBuilder scheduleBuilder = SimpleScheduleBuilder.simpleSchedule()
                .withIntervalInSeconds(1) //每一秒执行一次
                .repeatForever(); //永久重复，一直执行下去
        return TriggerBuilder.newTrigger()
                .forJob(jobDetail1())
                .withSchedule(scheduleBuilder)
                .build();
    }
    
}
