集群Quartz的配置方法
一般系统随着用户量的增长，慢慢的都会由单机走向集群，而很多时候我们又需要跑一些定时任务，Quartz就是为此而生，那么单机好办，集群中的Quartz又该如何配置呢？集群中的Quartz各节点之间是通过同一个数据库实例(准确的说是同一个数据库实例的同一套表)来感知彼此的，既然是通过数据库，那么就先看看数SQL文件
1. SQL文件
#
# Quartz seems to work best with the driver mm.mysql-2.0.7-bin.jar
#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

其实这个文件在Quartz的文档中是可以找到的，这里贴出来只是为了大家方便，建好数据库之后，接下来肯定就是看看数据源的问题了
2. quartz.properties
#============================================================== #Configure Main Scheduler Properties #============================================================== org.quartz.scheduler.instanceName = quartzScheduler org.quartz.scheduler.instanceId = AUTO #============================================================== #Configure JobStore #============================================================== org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate org.quartz.jobStore.tablePrefix = QRTZ_ org.quartz.jobStore.isClustered = true org.quartz.jobStore.clusterCheckinInterval = 60000 org.quartz.jobStore.dataSource = myDS #============================================================== #Configure DataSource #============================================================== org.quartz.dataSource.myDS.driver = org.quartz.dataSource.myDS.URL = org.quartz.dataSource.myDS.user = org.quartz.dataSource.myDS.password = org.quartz.dataSource.myDS.maxConnections = 30 #============================================================== #Configure ThreadPool #============================================================== org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount = 10 org.quartz.threadPool.threadPriority = 5 org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true
把这个properties文件放到classpath下，那么他就会覆盖掉quartz的jar中原有的配置文件，数据源的信息读者根据自己的情况填写。
在这个配置文件中，除了数据源、线程池等配置外，第四行和第五行我们指定了一个scheduler实例，实例ID为自动分配，第十三十四行指定了集群相应配置，检查间隔为60s，也就是一分钟。
3. 和spring集成的配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
<!-- 调度工厂 -->
<!-- 注意：更改配置时必须初始化数据库中的所有数据 -->
<bean id="mapScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" lazy-init="false" autowire="no" >
<property name="triggers">
<list>
<ref bean ="quartzTask"/>
</list>
</property>
<property name="applicationContextSchedulerContextKey" value="applicationContext" />
<property name="configLocation" value="classpath:quartz.properties" />
</bean>
<bean id="quartzTask" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail">
<ref bean="jobDetail" />
</property>
<property name="cronExpression" value="0 0/5 * * * ?"></property>
</bean>
<bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass">
<value>cn.bridgeli.quartz.MyDetailQuartzJobBean</value>
</property>
<property name="jobDataAsMap">
<map>
<entry key="targetObject" value="cacheRefreshQuartz" />
<entry key="targetMethod" value="execute" />
</map>
</property>
</bean>
<bean id="cacheRefreshQuartz" class="cn.bridgeli.task.QuartzImpl"/>
</beans>
由于MethodInvokingJobDetailFactoryBean 类中的 methodInvoking 方法，是不支持序列化的，因此在把 QUARTZ 的 TASK 序列化进入数据库时就会抛错，所以我们要自己实现MethodInvokingJobDetailFactoryBean 的功能，也就是第三十三行我们要用自己的MyDetailQuartzJobBean 去替换。
4. MyDetailQuartzJobBean
package cn.bridgeli.quartz;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;
import java.lang.reflect.Method;
public class MyDetailQuartzJobBean extends QuartzJobBean {
private String targetObject;
private String targetMethod;
private ApplicationContext ctx;
@Override
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
try {
Object otargetObject = ctx.getBean(targetObject);
Method m = null;
try {
m = otargetObject.getClass().getMethod(targetMethod, new Class[]{});
m.invoke(otargetObject, new Object[]{});
} catch (SecurityException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
}
} 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;
}
}
终于完成了，接下来我们就可以在集群中随心所欲的使用Quartz了。
