Spring+quartz 实现定时任务job集群配置

为什么要有集群定时任务?

因为如果多server都触发相同任务,又同时执行,那在99%的场景都是不适合的.比如银行每晚24:00都要汇总营业额.像下面3台server同时进行汇总,最终计算结果可能是真实结果的3倍,那对银行来说是无法想象的,完全不可接受.

集群定时任务工作原理

所以为了解决以上问题,每个server把将要及正在运行的job所有状态都即时同步到中央数据库,然后再次触发调用时从数据库中分析是否已有别的server正在运行相同job (同名同定时时间点的job属于相当job),如果相同job正在别的server运行,那么当前server忽略本次运行的job.

Quartz的 Task（11 张表）实例化采用数据库存储，基于数据库引擎及 High-Available 的策略（集群的一种策略）自动协调每个节点的 Quartz。

        System.out.print("job = "+i+" is running ");
        for(int j = 1 ; j <= 5;j++){//运行5秒
            System.out.print( j +" ");
            Thread.sleep(1*1000);
        }
        System.out.println();
        log.debug("end end end end end end end end end end end end ! job = "+ i);

被修改后的MethodInvokingJobDetailFactoryBean

因为spring自带的org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean的invoke()方法不能序列化job,导致无法把序列化后的信息写到表中,这可以算是spring的一个bug.

所以有民间大神修改后的MethodInvokingJobDetailFactoryBean,该Bean的invoke()方法可使job序列化,2拿来直接上手用吧(注意按包路径要和applicationContext-quartz.xml文件中的路径一致)

package king.springframework.scheduling.quartz;

import org.apache.commons.logging.Log;

/**
 * 该类可让生成的job可以序列化到数据库中,Spring自带的MethodInvokingJobDetailFactoryBean却不能序列化生成的job
 * This is a cluster safe Quartz/Spring FactoryBean implementation, which produces a JobDetail implementation that can invoke any no-arg method on any Class.
 * <p>
 * Use this Class instead of the MethodInvokingJobDetailBeanFactory Class provided by Spring when deploying to a web environment like Tomcat.
 * <p>
 * <b>Implementation</b><br>
 * Instead of associating a MethodInvoker with a JobDetail or a Trigger object, like Spring's MethodInvokingJobDetailFactoryBean does, I made the [Stateful]MethodInvokingJob, which is not persisted in the database, create the MethodInvoker when the [Stateful]MethodInvokingJob is created and executed.
 * <p>
 * A method can be invoked one of several ways:
 * <ul>
 * <li>The name of the Class to invoke (targetClass) and the static method to invoke (targetMethod) can be specified.
 * <li>The Object to invoke (targetObject) and the static or instance method to invoke (targetMethod) can be specified (the targetObject must be Serializable when concurrent=="false").
 * <li>The Class and static Method to invoke can be specified in one property (staticMethod). example: staticMethod = "example.ExampleClass.someStaticMethod"
 * <br><b>Note:</b>  An Object[] of method arguments can be specified (arguments), but the Objects must be Serializable if concurrent=="false".
 * </ul>
 * <p>
 * I wrote MethodInvokingJobDetailFactoryBean, because Spring's MethodInvokingJobDetailFactoryBean does not produce Serializable
 * JobDetail objects, and as a result cannot be deployed into a clustered environment like Tomcat (as is documented within the Class).
 * <p>
 * <b>Example</b>
 * <code>
 * <ul>
 *     &lt;bean id="<i>exampleTrigger</i>" class="org.springframework.scheduling.quartz.CronTriggerBean"&gt;
 * <ul>
    <i>&lt;!-- Execute example.ExampleImpl.fooBar() at 2am every day --&gt;</i><br>
    &lt;property name="<a href="http://www.opensymphony.com/quartz/api/org/quartz/CronTrigger.html">cronExpression</a>" value="0 0 2 * * ?" /&gt;<br>
    &lt;property name="jobDetail"&gt;
    <ul>
    &lt;bean class="frameworkx.springframework.scheduling.quartz.<b>MethodInvokingJobDetailFactoryBean</b>"&gt;
    <ul>
    &lt;property name="concurrent" value="<i>false</i>"/&gt;<br>
    &lt;property name="targetClass" value="<i>example.ExampleImpl</i>" /&gt;<br>
    &lt;property name="targetMethod" value="<i>fooBar</i>" /&gt;
    </ul>
    &lt;/bean&gt;
    </ul>
    &lt;/property&gt;
    </ul>
    &lt;/bean&gt;
    <p>
    &lt;bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"&gt;
    <ul>
    &lt;property name="triggers"&gt;
    <ul>
    &lt;list&gt;
    <ul>
    &lt;ref bean="<i>exampleTrigger</i>" /&gt;
    </ul>
    &lt;/list&gt;
    </ul>
    &lt;/property&gt;
    </ul>
    &lt;/bean&gt;
    </ul>
 * </code>
 * In this example we created a MethodInvokingJobDetailFactoryBean, which will produce a JobDetail Object with the jobClass property set to StatefulMethodInvokingJob.class (concurrent=="false"; Set to MethodInvokingJob.class when concurrent=="true"), which will in turn invoke the static <code>fooBar</code>() method of the "<code>example.ExampleImpl</code>" Class. The Scheduler is the heart of the whole operation; without it, nothing will happen.

quartz.properties

该配置文件一定要放在classpath目录下,因为SchedulerFactoryBean直接引用了configuration配置,所以还要配置相关数据源,见尾部Configure DataSource,其它保持原样即可,当然如果要调优的话里面参数肯定可以........

Main方法入口

package king.quartz.main;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {

    public static void main(String[] args) {
        //下面的非web形式直接加载可能会导致job同时加载并执行2次,原因不明(历史印象是用了log4j的日志会导致该情况)
        //只能做普通测试用,最好在Tomcat等容器中以web形式运行,且指明docBase路径
        new ClassPathXmlApplicationContext("applicationContext-quartz.xml");
    }

}

当我们启动2次Main方法,最终只有一个Main会运行,如下:

job = 65 is running 1 2 3 4 5
job = 66 is running 1 2 3 4 5
job = 67 is running 1 2 3 4 5
job = 68 is running 1 2 3 4 5
job = 69 is running 1 2 3 4 5
job = 70 is running 1 2 3 4 5
job = 71 is running 1 2 3 4 5

特别注意下面的sql版本要和squartz完全一致,在解压后的quartz\quartz-1.8.6\docs\dbTables文件夹在都有

遇见异常

异常一 No row exists in table QRTZ_LOCKS for lock named: TRIGGER_ACCESS.

　　该异常产生原因是,我项目中用的是quartz-1.8.6的jar,但由于quartz版本差异过大,在不知情的情况下从官网down了最新的quartz-2.2.3且把2.2.3的dbTables文件夹下的tables_oracle.sql导了进来.所以最终和1.8.6的表结构不一致.

　　就目前来看quartz-2.2.3的tables_oracle.sql比1.8.6的合理很多,1.8.6建表始化时还会建一些尴尬的外键关联,这是让我极不喜欢的一点.

异常如下,请点击展开

异常二 在xml配置中把定时任务的配置全删了,竟然还是执行了

这是spring的一个bug，所以需要去查询这三张表,它们储存了定时任务,把相关的定时任务删了即可

delete  from  QRTZ_CRON_TRIGGERS where TRIGGER_NAME = 'echannel.synchronizeJobTrigger';

delete  from  QRTZ_TRIGGERS where TRIGGER_NAME = 'echannel.synchronizeJobTrigger';

delete  from QRTZ_JOB_DETAILS where job_name = 'echannel.synchronize.content';

其它无关紧要的资料

SimpleTriggerBean

简易版Spring触发器,功能和org.springframework.scheduling.quartz.CronTriggerBean相似

<!-- ClusterSimpleTriggerBean 未使用,被注释了 -->
    <bean id="clusterSimpleTriggerBean" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
        <property name="startDelay" value="10000" />
        <property name="repeatInterval" value="10000" />
        <property name="jobDetail" ref="clusterJobDetail" />
    </bean>
