引入依赖:
<!-- Spring Quartz定时器 --> <dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz</artifactId> <version>2.2.1</version> <exclusions> <exclusion> <artifactId>slf4j-api</artifactId> <groupId>org.slf4j</groupId> </exclusion> </exclusions> </dependency> <dependency><!-- 该依赖必加,里面有sping对schedule的支持 --> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency> <!-- Spring Quartz定时器 -->
需要操作的任务:
package com.haier.datamart.utils; import java.text.SimpleDateFormat; import java.util.Date; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Configuration; import org.springframework.scheduling.annotation.EnableScheduling; import org.springframework.stereotype.Component; import com.haier.datamart.entity.AdminDatasourceConfig; import com.haier.datamart.entity.User; import com.haier.datamart.service.IAdminDatasourceConfigService; @Configuration @Component @EnableScheduling // 该注解必须要加 public class ScheduleTask { @Autowired private IAdminDatasourceConfigService configService; @Autowired private IAdminDatasourceConfigService datasourceConfigService; public void scheduleTest(){ SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); System.out.println("我是定时任务类,现在的执行时间是::::::" + sdf.format(new Date())+"即将执行表扫描"); List<AdminDatasourceConfig> configs = configService.getAll(); System.out.println(configs); for(AdminDatasourceConfig config:configs){ User user=new User(); user.setId(config.getUserId()); Thread rthread = new Thread(new ITableScanUtils(config.getId(), user,datasourceConfigService)); rthread.start(); } } }
对该任务进行配置:
package com.haier.datamart.utils; import org.quartz.Trigger; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.scheduling.quartz.CronTriggerFactoryBean; import org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean; import org.springframework.scheduling.quartz.SchedulerFactoryBean; @Configuration public class QuartzConfigration { @Bean(name = "jobDetail") public MethodInvokingJobDetailFactoryBean detailFactoryBean(ScheduleTask task) { // ScheduleTask为需要执行的任务 MethodInvokingJobDetailFactoryBean jobDetail = new MethodInvokingJobDetailFactoryBean(); /* * 是否并发执行 * 例如每5s执行一次任务,但是当前任务还没有执行完,就已经过了5s了, * 如果此处为true,则下一个任务会bing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,再开始执行 */ jobDetail.setConcurrent(true); jobDetail.setName("scheduler");// 设置任务的名字 jobDetail.setGroup("scheduler_group");// 设置任务的分组,这些属性都可以存储在数据库中,在多任务的时候使用 /* * 这两行代码表示执行task对象中的scheduleTest方法。定时执行的逻辑都在scheduleTest。 */ jobDetail.setTargetObject(task); jobDetail.setTargetMethod("scheduleTest"); return jobDetail; } @Bean(name = "jobTrigger") public CronTriggerFactoryBean cronJobTrigger(MethodInvokingJobDetailFactoryBean jobDetail) { CronTriggerFactoryBean tigger = new CronTriggerFactoryBean(); tigger.setJobDetail(jobDetail.getObject()); // tigger.setCronExpression("0/6 * * * * ?");// 表示每隔6秒钟执行一次 tigger.setCronExpression("0 0 1 * * ?");// 表示每天晚上一点执行一次 //tigger.set tigger.setName("myTigger");// trigger的name return tigger; } @Bean(name = "scheduler") public SchedulerFactoryBean schedulerFactory(Trigger cronJobTrigger) { SchedulerFactoryBean bean = new SchedulerFactoryBean(); //设置是否任意一个已定义的Job会覆盖现在的Job。默认为false,即已定义的Job不会覆盖现有的Job。 bean.setOverwriteExistingJobs(true); // 延时启动,应用启动5秒后 ,定时器才开始启动 bean.setStartupDelay(5); // 注册定时触发器 bean.setTriggers(cronJobTrigger); return bean; } //多任务时的Scheduler,动态设置Trigger。一个SchedulerFactoryBean可能会有多个Trigger @Bean(name = "multitaskScheduler") public SchedulerFactoryBean schedulerFactoryBean(){ SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean(); return schedulerFactoryBean; } }
