Springboot+Quartz 实战
1、添加依赖
2、添加注解
工程启动类：
@SpringBootApplication
@EnableScheduling //开启定时注解
public class QuartzApplication {
public static void main(String[] args) {
SpringApplication.run(QuartzApplication.class, args);
}
}
3、添加配置
配置类
@Configuration
public class QuartzConfigration {
/**
* 配置定时任务
* @param task
* @return
*/
@Bean(name="sayHelloJodDetail")
public MethodInvokingJobDetailFactoryBean detailFactoryBean(ScheduleTaskImpl task){
MethodInvokingJobDetailFactoryBean jodDetail = new MethodInvokingJobDetailFactoryBean();
/**
* 是否并发执行
* 例如：每5秒执行一次任务，但是当前任务还没有执行完，就已经过了5秒了。
* 如果此处为true，则下一个任务执行；
* 如果此处为false，则下一个任务会等待上一个任务执行完后再执行
*/
jodDetail.setConcurrent(true);
/*
* 为需要执行的实体类对象的对象
*/
jodDetail.setTargetObject(task);
/*
* sayHello 为需要执行的方法
* 通过这几个配置，告诉JodDetailFactoryBean 我们需要定时执行scheduleTask 类中的sayHello 方法
*/
jodDetail.setTargetMethod("sayHello");
return jodDetail;
}
/**
* 配置定时任务的触发器，也就是什么时候出发执行定时任务
* @param jodDetail
* @return
*/
@Bean(name="sayHelloJodTrigger")
public CronTriggerFactoryBean cronJodTrigger(JobDetail sayHelloJodDetail){
CronTriggerFactoryBean trigger = new CronTriggerFactoryBean();
trigger.setJobDetail(sayHelloJodDetail);
/*
* 初始时的cron 表达式 (每秒执行一次)
*/
trigger.setCronExpression("*/1 * * * * ?");
/*
* 设置trigger 的分组和名称
*/
trigger.setGroup("payMentGroup");
trigger.setName("payMent");
return trigger;
}
/**
* 配置定时任务
* @param task
* @return
*/
@Bean(name="sayHello2JodDetail")
public MethodInvokingJobDetailFactoryBean detailFactoryBean2(ScheduleTaskImpl task){
MethodInvokingJobDetailFactoryBean jodDetail = new MethodInvokingJobDetailFactoryBean();
/**
* 是否并发执行
* 例如：每5秒执行一次任务，但是当前任务还没有执行完，就已经过了5秒了。
* 如果此处为true，则下一个任务执行；
* 如果此处为false，则下一个任务会等待上一个任务执行完后再执行
*/
jodDetail.setConcurrent(false);
/*
* 为需要执行的实体类对象的对象
*/
jodDetail.setTargetObject(task);
/*
* sayHello 为需要执行的方法
* 通过这几个配置，告诉JodDetailFactoryBean 我们需要定时执行scheduleTask 类中的sayHello 方法
*/
jodDetail.setTargetMethod("sayHello2");
return jodDetail;
}
/**
* 配置定时任务的触发器，也就是什么时候出发执行定时任务
* @param jodDetail
* @return
*/
@Bean(name="sayHello2JodTrigger")
public CronTriggerFactoryBean cronJodTrigger2(JobDetail sayHello2JodDetail){
CronTriggerFactoryBean trigger = new CronTriggerFactoryBean();
trigger.setJobDetail(sayHello2JodDetail);
/*
*初始时的cron 表达式 (每秒执行一次)
*/
trigger.setCronExpression("*/5 * * * * ?");
/*
* 设置trigger 的分组和名称
*/
trigger.setGroup("payMentGroup");
trigger.setName("payMent2");
return trigger;
}
/**
* 定义quartz 调度工厂
* @param cronJodTrigger
* @return
*/
@Bean(name="sheduler")
public SchedulerFactoryBean shedulerFactory(Trigger ...trigger){
Properties pro = new Properties();
// 配置实例
pro.put("org.quartz.scheduler.instanceId", "AUTO");
// 配置线程池
pro.put("org.quartz.threadPool.threadCount", "5");
/*备注：如果使用数据库来实现quartz分布式部署，则需要添加相关配置
SchedulerFactoryBean bean = new SchedulerFactoryBean();
bean.setQuartzProperties(pro);
/*
* 用于quartz 集群，QuartzSchedule 启动时更新已存在的jod
*/
bean.setOverwriteExistingJobs(true);
/*
* 延时启动，应用启动1秒后
*/
bean.setStartupDelay(1);
/*
* 注册触发器
*/
bean.setTriggers(trigger);
return bean;
}
}
