Spring----Quartz总结
?
Quartz的关键元素结构图：
?
二种Triger：
1.Simple triggers
?
2.Cron triggers
?
3.code
// Initiate a Schedule Factory SchedulerFactory schedulerFactory = new StdSchedulerFactory(); // Retrieve a scheduler from schedule factory Scheduler scheduler = schedulerFactory.getScheduler(); // current time long ctime = System.currentTimeMillis(); // Initiate JobDetail with job name, job group, and executable job class JobDetail jobDetail = new JobDetail("jobDetail-s1", "jobDetailGroup-s1", SimpleQuartzJob.class); // Initiate SimpleTrigger with its name and group name SimpleTrigger simpleTrigger = new SimpleTrigger("simpleTrigger", "triggerGroup-s1"); // set its start up time simpleTrigger.setStartTime(new Date(ctime)); // set the interval, how often the job should run (10 seconds here) simpleTrigger.setRepeatInterval(10000); // set the number of execution of this job, set to 10 times. // It will run 10 time and exhaust. simpleTrigger.setRepeatCount(100); // set the ending time of this job. // We set it for 60 seconds from its startup time here // Even if we set its repeat count to 10, // this will stop its process after 6 repeats as it gets it endtime by then. //simpleTrigger.setEndTime(new Date(ctime + 60000L)); // set priority of trigger. If not set, the default is 5 //simpleTrigger.setPriority(10); // schedule a job with JobDetail and Trigger scheduler.scheduleJob(jobDetail, simpleTrigger); // start the scheduler scheduler.start();?
三、Spring中的配置参见结构和调用方式
<description>Quartz的本地Cron式执行任务配置</description><!-- Quartz本地Schduler --><bean id="localQuartzScheduler" lazy-init="false"><!-- Triggers集成 --><property name="triggers"><list><ref bean="reportSenderTrigger" /></list></property><!-- Quartz配置 --><property name="quartzProperties"><props><prop key="org.quartz.threadPool.threadCount">5</prop></props></property><!-- 启动时延期3秒开始任务 --><property name="startupDelay" value="15" /></bean><!-- Cron式Trigger定义 --><bean id="reportSenderTrigger" ref="reportSenderDetail" /><!-- 每天,朝九晚五工作时间内每50mins执行一次 --><property name="cronExpression" value="0 0/50 9-17 ? * *I" /></bean><!-- Cron reportSenderDetail, 基于MethodInvokingJobDetailFactoryBean调用普通Spring Bean --><bean id="reportSenderDetail" ref="reportSender" /><property name="targetMethod" value="execute" /><!-- 同一任务在前一次执行未完成而Trigger时间又到时是否并发开始新的执行, 默认为true. --><property name="concurrent" value="true" /></bean><!-- 被Cron执行的普通Spring Bean --><bean id="reportSender" />?
