1.1 java中使用quartz

1.1.1集成jar包

1.1.2创建job相关的类

public class HelloQuatzJob implements Job{
	@Override
	public void execute(JobExecutionContext arg0) throws JobExecutionException {
		// TODO Auto-generated method stub
		System.out.println("定时任务执行时间 "+new Date());
	}
}

1.1.3调用类

public class TestJob {
	public static void main(String[] args) throws SchedulerException {
		SchedulerFactory chedule=new StdSchedulerFactory();
		Scheduler scheduler = chedule.getScheduler();
		//定义一个任务
		JobDetail detail=JobBuilder.
				newJob(HelloQuatzJob.class)
				.withIdentity("testjob1", "group1")
				.build();
		Date runTime = DateBuilder.evenSecondDateAfterNow(); 
		//定义一个触发器
		Trigger trigger=TriggerBuilder.newTrigger()
				.withIdentity("trigger1", "group1")
				.startAt(runTime)//设置触发开始时间
				.withSchedule(
					SimpleScheduleBuilder.repeatSecondlyForever(2)
					.withIntervalInSeconds(2)//时间间隔
				).build();
		scheduler.scheduleJob(detail, trigger);
		scheduler.start();
    }
}

1.1.4结果图

1.2 spring集成quartz

1.2.1集成jar包同1.1.1

1.2.2创建简单job 

public class SimpleSpringQuatz {
	public void printJob(){
		System.out.println("定时任务执行时间 "+new Date());
	}
}

1.2.3创建复杂job

public class ComplexSchejob extends QuartzJobBean{
	private ComplexJobClasExe complexBean;
	@Override
	protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException {
		// TODO Auto-generated method stub
		complexBean.print();
	}
	public ComplexJobClasExe getComplexBean() {
		return complexBean;
	}
	public void setComplexBean(ComplexJobClasExe complexBean) {
		this.complexBean = complexBean;
	}
}

public class ComplexJobClasExe {
	public void print(){
		System.out.println("复杂任务:"+new Date());
	}
}

1.2.4 spring中进行配置

1.3 spring+quartz集群

1.3.1 建表


如上图所示从官网上下载quartz的包，找到对应的SQL并且执行对应的sql


生成quartz框架所需要的工作表。

1.3.2添加依赖

1.3.4 添加quartz.properties

#============================================================================

org.quartz.scheduler.instanceName: TestScheduler
org.quartz.scheduler.instanceId: AUTO
org.quartz.jobStore.clusterCheckinInterval=20000

#org.quartz.jobStore.tablePrefix: QRTZ_
org.quartz.jobStore.isClustered: true

#============================================================================

#org.quartz.plugin.jobInitializer.failOnFileNotFound: true
#org.quartz.plugin.jobInitializer.scanInterval: 120
#org.quartz.plugin.jobInitializer.wrapInUserTransaction: false

使用集群模式的配置

org.quartz.scheduler.instanceId: AUTO

org.quartz.jobStore.clusterCheckinInterval=20000

org.quartz.jobStore.isClustered: true

1.3.5重写QuartzJobBean类

public class QuartJobClassBean extends QuartzJobBean{
	    protected final Log logger = LogFactory.getLog(getClass());
	    private String targetObject;
	    private String targetMethod;
	    private ApplicationContext ctx;
	  
	    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
	        try {
	            logger.info("execute [" + targetObject + "] at once>>>>>>");
	            Object otargetObject = ctx.getBean(targetObject);
	            Method m = null;
	            try {
	              m = otargetObject.getClass().getMethod(targetMethod, new Class[] {});
	              m.invoke(otargetObject, new Object[] {});
	            } catch (SecurityException e) {
	                logger.error(e.getMessage());
	            } catch (NoSuchMethodException e) {
	                logger.error(e.getMessage());
	            }
	        } catch (Exception e) {
	            throw new JobExecutionException(e);
	        }
	    }

	    public void setApplicationContext(ApplicationContext applicationContext){
	        this.ctx=applicationContext;
	    }
	    public void setTargetObject(String targetObject) {
	        this.targetObject = targetObject;
	    }

	    public void setTargetMethod(String targetMethod) {
	        this.targetMethod = targetMethod;
	    }
}

1.3.6编写任务类

public class TestQuartJobClass {
	public void printjob(){
		System.out.println("定时任务0:"+new Date());
	}
	public void print(){
		System.out.println("定时任务1"+new Date());
	}
}

1.3.7集群部署


模拟分布式部署

1.3.8启动测试

由以上两个图可以看出，任务调度只在一个服务器上运行了，保证了任务的不重复执行，现在假如我做一件事情就是停掉tomcaT的服务器。quartz框架将自动帮我们把任务切换到另一个服务器上执行


如上图所示tomcat停掉以后，任务自动切换到了另一个上，并且可以看出在15-50之间，在故障切换的过程中有6次定时任务没有跑，所以切换以后备用主机将会自动补跑故障以前的数据。
