Spring与Quartz集成详解

企业开发 2018-05-10 03:20:26 阅读次数: 0
首先这个所有的依赖包就不需要多讲了，首先下载Quazrt发布包，解压，运行doc文件夹下（E:\Quartz\quartz-2.2.3\docs\dbTables）的tables_mysql_innodb.sql脚本
新建job
//MyJob 普通job，这个不需要实现org.quartz.Job 
package job;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class MyJob {
    Logger log = LoggerFactory.getLogger(MyJob.class);
    public void work () {
        // 此任务仅打印日志便于调试、观察
    	log.info("==================:"+this.getClass().getName() + " was just triggered...");
    }  
}

//MyQuartzJob，这个job因为我们要把job持久化到RDB所以要实现org.quartz.Job 
package job;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class MyQuartzJob implements Job{
	Logger log = LoggerFactory.getLogger(MyQuartzJob.class);
	@Override
	public void execute(JobExecutionContext jobexecutioncontext)
			throws JobExecutionException {
		log.info("==================:"+this.getClass().getName() + " was just triggered...");
	}
}

说明：
定时任务配置有两种方式
第一种：MethodInvokingJobDetailFactoryBean 
<bean id="myJobDetail"	class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject" ref="myJob" />
		<property name="targetMethod" value="work" />
		<!-- <property name="concurrent" value="false" /> -->
</bean>

如果用这种方式的话，要屏蔽一下配置 
<property name="dataSource" ref="dataSource" />
		<property name="quartzProperties">
			<props>
				<prop key="org.quartz.scheduler.instanceName">defaultScheduler</prop>
				<prop key="org.quartz.scheduler.instanceId">AUTO</prop>
				<!-- 线程池配置 -->
				<prop key="org.quartz.threadPool.class">org.quartz.simpl.SimpleThreadPool</prop>
				<prop key="org.quartz.threadPool.threadCount">20</prop>
				<prop key="org.quartz.threadPool.threadPriority">5</prop>
				<!-- JobStore配置 -->
				<prop key="org.quartz.jobStore.class">org.quartz.impl.jdbcjobstore.JobStoreTX</prop>
				<!-- 集群配置 -->
				<prop key="org.quartz.jobStore.isClustered">true</prop>
				<prop key="org.quartz.jobStore.clusterCheckinInterval">15000</prop>
				<prop key="org.quartz.jobStore.maxMisfiresToHandleAtATime">1</prop>
				<prop key="org.quartz.jobStore.misfireThreshold">120000</prop>
				<!-- 表名配置 -->
				<prop key="org.quartz.jobStore.tablePrefix">QRTZ_</prop>
			</props>
		</property>

第二种：JobDetailFactoryBean 
<bean id="myQuartzJobDetail"
		class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
		<property name="jobClass" value="job.MyQuartzJob" />
		<property name="name" value="myQuartzJob" />
		<!-- 任务完成之后是否依然保留到数据库，默认false -->
		<property name="durability" value="true" />
</bean>

主要是JobDetailFactory得实现不同，第一种不需要实现org.quartz.Job，而第二种需要实现org.quartz.Job；为什么会有这两种方式呢，用的时候该用那种方式，第一种方式定时任务存在RAM中，应用启动时，任务信息及任务调度信息易丢失，要避免任务信息及任务调度信息，需将任务相关信息持久化到RDB，这就是第二种方式的job为什么要实现org.quartz.Job原因，因为保存到数据库需要job-bean的相关信息。
了解更多关于任务持久化到RDB，请参考：
