Spring與Quartz集成詳解

首先這個所有的依賴包就不需要多講了，首先下載Quazrt發佈包，解壓，運行doc文件夾下（E:\Quartz\quartz-2.2.3\docs\dbTables）的tables_mysql_innodb.sql腳本 
新建job 
//MyJob 普通job，這個不需要實現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 () {
        // 此任務僅打印日誌便於調試、觀察
        log.info("==================:"+this.getClass().getName() + " was just triggered...");
    }
}

//MyQuartzJob，這個job因爲我們要把job持久化到RDB所以要實現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...");
    }
}

說明： 
定時任務配置有兩種方式 
第一種：MethodInvokingJobDetailFactoryBean 下載

<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>

如果用這種方式的話，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>
                <!-- 線程池配置 -->
                <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>
                <!-- 集羣配置 -->
                <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>

第二種：JobDetailFactoryBean 下載

<bean id="myQuartzJobDetail"
        class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <property name="jobClass" value="job.MyQuartzJob" />
        <property name="name" value="myQuartzJob" />
        <!-- 任務完成之後是否依然保留到數據庫，默認false -->
        <property name="durability" value="true" />
</bean>

主要是JobDetailFactory得實現不同，第一種不需要實現org.quartz.Job，而第二種需要實現org.quartz.Job；爲什麼會有這兩種方式呢，用的時候該用那種方式，第一種方式定時任務存在RAM中，應用啓動時，任務信息及任務調度信息易丟失，要避免任務信息及任務調度信息，需將任務相關信息持久化到RDB，這就是第二種方式的job爲什麼要實現org.quartz.Job原因，因爲保存到數據庫需要job-bean的相關信息。
