与spring集成实际就是将Jobdetail、Trigger、Scheduler交给spring管理。常用的集成方式每个都有两种
1. 使用Quartz配置作业(JobDetail)两种方式:
MethodInvokingJobDetailFactoryBean
JobDetailFactoryBean
方式一:使用MethodInvokingJobDetailFactoryBean(简单，需要注入一个执行任务的bean对象和执行的方法名称)
1.调用firstBean的printMessage方法
2.FirstBean类(普通的java类，交给spring管理)
package cn.qlq.quartz; import java.text.SimpleDateFormat; import java.util.Date; import org.springframework.stereotype.Component; @Component("firstBean") public class FirstBean { public void printMessage() { // 打印当前的执行时间，格式为2017-01-01 00:00:00 Date date = new Date(); SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); System.out.println("FirstBean Executes!" + sf.format(date)); } }
方式二：使用JobDetailFactoryBean(想要更加灵活的话就是用这种方式，可以使用jobDataMap传递参数)
1.需要给作业传递数据，想要更加灵活的话就是用这种方式
2.FirstScheduleJob类（继承QuartzJobBean，重写executeInternal方法,使用jobDataMap注入一个SecondBean）
package cn.qlq.quartz; import java.text.SimpleDateFormat; import java.util.Date; import org.quartz.JobExecutionContext; import org.quartz.JobExecutionException; import org.quartz.JobKey; import org.springframework.scheduling.quartz.QuartzJobBean; public class FirstScheduledJob extends QuartzJobBean{ private SecondBean secondBean; public void setSecondBean(SecondBean secondBean) { this.secondBean = secondBean; } @Override protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException { //可以获取JobDetail的标识信息 JobKey key = arg0.getJobDetail().getKey(); System.out.println("job key:"+"name "+key.getName()); System.out.println("job key:"+"group "+key.getGroup()); Date date = new Date(); SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); System.out.println("FirstScheduledJob Executes!" + sf.format(date)); this.secondBean.printMessage(); } }
3.SecondBean .java
package cn.qlq.quartz; import java.text.SimpleDateFormat; import java.util.Date; import org.springframework.stereotype.Component; @Component("secondBean") public class SecondBean { public void printMessage() { // 打印当前的执行时间，格式为2017-01-01 00:00:00 Date date = new Date(); SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); System.out.println("SecondBean Executes:" + sf.format(date)); } }
2. trigger也有两种常见的配置方式(SimpleTrigger和CronTrigger)----需要将JobDetail注入到trigger中
1.第一种:simpletrigger
<!-- 第一种: 距离当前时间1秒之后执行，之后每隔两秒钟执行一次(SimpleTrigger用法) --> <bean id="mySimpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean"> <property name="jobDetail" ref="simpleJobDetail"/> <property name="startDelay" value="1000"/> <property name="repeatInterval" value="2000"/> </bean>
2.第二种:cronTrigger
<!-- 第二种:每隔5秒钟执行一次 (CronTrigger用法)--> <bean id="myCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"> <property name="jobDetail" ref="firstComplexJobDetail"/> <property name="cronExpression" value="0/5 * * ? * *"/> </bean> <bean id="fetchDataTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"> <property name="jobDetail" ref="fetchDataJobDetail"/> <property name="cronExpression" value="0/5 * * ? * *"/> </bean>
3.Scheduler也有两种配置方式:
1.第一种：分别注入JobDetails和Triggers
<!-- 第一种:Schduler的创建以及指定jobDetail和trigger--> <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="jobDetails"> <list> <ref bean="simpleJobDetail"/> <ref bean="firstComplexJobDetail"/> </list> </property> <property name="triggers"> <list> <ref bean="mySimpleTrigger"/> <ref bean="myCronTrigger"/> </list> </property> </bean>
2.第二种:只注入triggers，实际是在第一种的基础上取消注入jobDetails
<!--第二种方式:只指定trigger --> <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref bean="fetchDataTrigger"/> <!--<ref bean="fetchDataTrigger2"/> --> </list> </property> </bean>

总结:
spring整合quartz的时候也是将quartz的三个主要元素交给spring管理，JobDatail、Trigger、Scheduler。
JobDetail有两种方式，MethodInvokingJobDetailFactoryBean 和 JobDetailFactoryBean (推荐这种，更加灵活，可以传入利用jobDataMap参数),需要将执行任务的bean和bean的方法注入
Trigger主要也是使用SimpleTrigger和CronTrigger(推荐这种，更加灵活)，需要将jobDetail传入Trigger
Scheduler使用SchedulerFactoryBean工厂创建，需要传入jobDetails集合(可选，不注入这个也可以)和triggers集合，可以配置多个jobDetail(可选，可以不注入)和Trigger
在测试的时候我们可以先http接口进行测试，一般定时任务也会暴露一个http接口 进行手动的进行定时任务的操作。而且定时任务最好不要太过于频繁的拉取数据，类似于同步拉取数据等操作最好是夜间进行操作。不过具体的也是看业务需求。。。。。。。。。。。。。。。。。。。。。。
当然也可以用java.util.concurrent并发包中的ScheduledThreadPoolExecutor内容实现任务调度的功能，参考:https://www.cnblogs.com/qlqwjy/p/9470414.html
