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。
