quartz与Spring的结合实现集群和非集群的定时器

版本

<spring.version>3.1.0.RELEASE</spring.version><dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz</artifactId> <version>1.8.6</version></dependency>

非集群

application-quartz-singleton.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"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"><bean id="SingetonTimerSample" class="com.freud.test.demo.SingletonTimerSample" /><!--配置调度具体执行的方法 --><bean id="SingetonJobSample"class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"><property name="targetObject" ref="SingetonTimerSample" /><property name="targetMethod" value="helloWorld" /><property name="concurrent" value="false" /></bean><!--配置调度执行的触发的时间 --><bean id="SingletonTriggerSample" class="org.springframework.scheduling.quartz.CronTriggerBean"><property name="jobDetail" ref="SingetonJobSample" /><property name="cronExpression"><!-- 每5秒执行一次 --><value>0/5 * * * * ?</value></property></bean><!-- quartz的调度工厂 调度工厂只能有一个，多个调度任务在list中添加 --><bean id="singletonSchedulerFactory" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"><property name="triggers"><list><!-- 所有的调度列表 --><ref local="SingletonTriggerSample" /></list></property></bean></beans>

SingletonTimerSample.java

package com.freud.test.demo;import java.util.Date;import org.springframework.beans.factory.annotation.Autowired;/** * @author Freud */public class SingletonTimerSample{    @Autowired    private TestService testService;        public void helloWorld()    {        System.out.println(new Date() + "Hello Sample Singeton Timer!");        try        {            testService.index("Singleton");        }        catch (Exception e)        {            e.printStackTrace();        }    }}

TestService.java

package com.freud.test.demo;import java.util.Date;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;/** * @author Freud */ @Service("TestService")public class TestService{        public void index(String mode)        throws Exception    {        System.out.println(new Date() + "[" + mode + "]Test Quartz with Spring IOC");    }}

集群方式(支持Spring注入)

application-quartz-cluster.xml

ClusterTimerSample.java

package com.freud.test.demo;import java.util.Date;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.scheduling.quartz.QuartzJobBean;/** * @author Freud */public class ClusterTimerSample extends QuartzJobBean{    @Autowired    private TestService testService;    @Override    protected void executeInternal(JobExecutionContext arg0)        throws JobExecutionException    {        System.out.println(new Date() + "Hello Cluster Timer sample!");        try        {            testService.index("cluster");        }        catch (Exception e)        {            // TODO Auto-generated catch block            e.printStackTrace();        }    }    }

AutoWiringSpringBeanJobFactory.java

package com.freud.test;import org.quartz.spi.TriggerFiredBundle;import org.springframework.beans.factory.config.AutowireCapableBeanFactory;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;import org.springframework.scheduling.quartz.SpringBeanJobFactory;/** * @author Freud */public class AutoWiringSpringBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware{    private transient AutowireCapableBeanFactory beanFactory;        public void setApplicationContext(final ApplicationContext context)    {        beanFactory = context.getAutowireCapableBeanFactory();    }        @Override    protected Object createJobInstance(final TriggerFiredBundle bundle)        throws Exception    {        final Object job = super.createJobInstance(bundle);        beanFactory.autowireBean(job);        return job;    }}

其他

最后把application-quartz-cluster.xml和application-quartz-singleton.xml引入Spring的ApplicationContext.xml文件就可以了

遇到的问题

数据库版本问题，在Mysql5.6.21下运行集群一直不成功,程序未报任何错误，但是集群Job不会运行，而切到5.5.*下就可以了。
Quartz支持插件式的配置开发，而要使用的话，就需要使用如下的Jar包

<dependency>    <groupId>javax.transaction</groupId>    <artifactId>jta</artifactId>    <version>1.1</version></dependency><dependency>    <groupId>quartz</groupId>    <artifactId>quartz</artifactId>    <version>1.5.2</version></dependency>

Spring 3. 只支持quartz 1.
Oracle JDK从5.0开始在某些条件(特别是多线程)下已经不建议使用Timer，而是使用 java.util.concurrent.ScheduledThreadPoolExecutor来代替。
Quartz集群中给机器命名的方式(InstanceIdGenerator)有三种，分别是 HostnameInstanceIdGenerator, SimpleInstanceIdGenerator和 SystemPropertyInstanceIdGenerator，在 org.quartz.scheduler.instanceId= AUTO 配置为AUTO即使用默认的SimpleInstanceIdGenerator，即

package org.quartz.simpl;import java.net.InetAddress;import org.quartz.SchedulerException;import org.quartz.spi.InstanceIdGenerator;/** * The default InstanceIdGenerator used by Quartz when instance id is to be * automatically generated.  Instance id is of the form HOSTNAME + CURRENT_TIME. *  * @see InstanceIdGenerator * @see HostnameInstanceIdGenerator */public class SimpleInstanceIdGenerator implements InstanceIdGenerator {    public String generateInstanceId() throws SchedulerException {        try {            return InetAddress.getLocalHost().getHostName() + System.currentTimeMillis();        } catch (Exception e) {            throw new SchedulerException("Couldn't get host name!", e);        }    }}

但是在linux环境下，如果没有配置机器别名的话，就会在 InetAddress.getLocalHost().getHostName()报错，解决方案有2步，先 hostname看下机器名是否是乱码，如果不是，就在 /etc/hosts文件中添加
