标签：slf4j RKE static script 编写 ada tco ssh sys
1.添加pom.xml
<dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz</artifactId> <version>2.2.3</version> </dependency> <!-- https://mvnrepository.com/artifact/org.quartz-scheduler/quartz-jobs --> <dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz-jobs</artifactId> <version>2.2.3</version> </dependency>
2.添加配置文件，或者不添加使用默认也行，默认线程池数量为10
打开quartz的jar包，可以找到该配置 quartz.properties
复制到资源目录下修改如下
org.quartz.scheduler.instanceName: DemoQuartz org.quartz.scheduler.rmi.export: false org.quartz.scheduler.rmi.proxy: false org.quartz.scheduler.wrapJobExecutionInUserTransaction: false org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool #线程池数量 org.quartz.threadPool.threadCount: 1 org.quartz.threadPool.threadPriority: 5 org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread: true org.quartz.jobStore.misfireThreshold: 60000 org.quartz.jobStore.class: org.quartz.simpl.RAMJobStore
3.编写job类
DemoJob.class,HelloJob.class
实现接口 org.quartz.Job
package com.yun.base.job;
import java.util.Calendar;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.SchedulerException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class HelloJob implements Job {
private static final Logger LOGGER = LoggerFactory.getLogger(HelloJob.class);
@Override
public void execute(JobExecutionContext context)
throws JobExecutionException {
try {
LOGGER.info(context.getScheduler().getSchedulerName());
String jobParam = (String) context.getJobDetail().getJobDataMap().get("jobParam");
if (jobParam != null) {
LOGGER.info(jobParam.toString());
}
LOGGER.info(Integer.toString(Calendar.getInstance().get(Calendar.SECOND)));
} catch (SchedulerException e) {
e.printStackTrace();
}
}
}
4.编写任务管理工具类 JobSchedule
package com.yun.util;
import org.quartz.CronScheduleBuilder;
import org.quartz.CronTrigger;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.JobKey;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.TriggerKey;
import org.quartz.impl.StdSchedulerFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class JobSchedule {
private static final Logger LOGGER = LoggerFactory.getLogger(JobSchedule.class);
private static SchedulerFactory gSchedulerFactory = new StdSchedulerFactory();
private static String JOB_GROUP_NAME = "YUN_JOBGROUP_NAME";
private static String TRIGGER_GROUP_NAME = "YUN_TRIGGERGROUP_NAME";
private JobSchedule(){
}
/**

*/
public static void addJob(String jobName, Class cls, String cron)
throws SchedulerException {
Scheduler sched = gSchedulerFactory.getScheduler();

.build();// 产生触发器

5.测试类
@Test
public void testTask() {
try {
String job_name = "动态任务调度";
System.out.println("【系统启动】开始(每1秒输出一次)...");
JobSchedule.addJob(job_name, DemoJob.class, "0/1 * * * * ?");
Thread.sleep(5000);
System.out.println("【修改时间】开始(每2秒输出一次)...");
JobSchedule.modifyJobTime(job_name, "10/2 * * * * ?");
Thread.sleep(6000);
System.out.println("【移除定时】开始...");
JobSchedule.removeJob(job_name);
System.out.println("【移除定时】成功");
System.out.println("【再次添加定时任务】开始(每10秒输出一次)...");
JobSchedule.addJob(job_name, HelloJob.class, "*/10 * * * * ?");
Thread.sleep(60000);
System.out.println("【移除定时】开始...");
JobSchedule.removeJob(job_name);
System.out.println("【移除定时】成功");
} catch (Exception e) {
e.printStackTrace();
}
}
