quartz集群配置

quartz有两种注入方式，MethodInvokingJobDetailFactoryBean和JobDetailBean。

这里我用的是JobDetailBean。（MethodInvokingJobDetailFactoryBean也试了下，无奈不成功，看网上有人说重写两个类文件，试了下也不行，只好用JobDetailBean了）

1.下载quartz-1.8.6包，包的的docs文件夹里有数据库建表sql，quartz集群需要将任务信息实例化到数据库中，然后各个节点从库中读取任务信息。

2.在src中添加quartz.properties文件。

org.quartz.scheduler.instanceName = DefaultQuartzScheduler
org.quartz.scheduler.instanceId = AUTO 

org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 10
org.quartz.threadPool.threadPriority = 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true

org.quartz.jobStore.misfireThreshold = 60000

org.quartz.jobStore.selectWithLockSQL=SELECT * FROM {0}LOCKS UPDLOCK WHERE LOCK_NAME \= ? 
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.useProperties = false
org.quartz.jobStore.dataSource = quartzdataSource
org.quartz.jobStore.tablePrefix = QRTZ_

org.quartz.jobStore.isClustered = true
org.quartz.jobStore.clusterCheckinInterval = 20000

3.src中添加applicationContext-Quartz.xml文件，内容如下,quartz自带的连接池是DBCP，这个连接池问题很多性能也不好，所以改成了c3p0

    <bean id="syncSpOriinfoBean" class="org.springframework.scheduling.quartz.JobDetailBean">

        </property>
        <property name="applicationContextSchedulerContextKey" value="applicationContext" />
    </bean>

</beans> 

4.根据 QuartzJobBean 来重写一个自己的类，然后使用 SPRING 把这个重写的类注入 appContext 中后，再使用 AOP 技术反射出原有的 quartzJobx( 就是开发人员原来已经做好的用于执行 QUARTZ 的 JOB 的执行类 ) 。

 public class SyncSpOriinfoServiceClient extends QuartzJobBean {

    private final Log log = LogFactory.getLog(SyncSpOriinfoServiceClient.class);

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        try {

            log.info("execute [" + targetObject + "] at once>>>>>>");
            ApplicationContext ctx =  new ClassPathXmlApplicationContext(new String[]{"classpath:applicationContext.xml","classpath:applicationContext-quartz.xml"}); 
            Object otargetObject = ctx.getBean(targetObject);
            Method m = null;
            try {
                m = otargetObject.getClass().getMethod(targetMethod, new Class[]{});

                m.invoke(otargetObject, new Object[]{});
            }
            catch (SecurityException e) {
                log.error(e);
            }
            catch (NoSuchMethodException e) {
                log.error(e);
            }

        }
        catch (Exception e) {
            throw new JobExecutionException(e);
        }
    }

    private String targetObject;
    private String targetMethod;

    public void setTargetObject(String targetObject) {
        this.targetObject = targetObject;
    }

    public void setTargetMethod(String targetMethod) {
        this.targetMethod = targetMethod;
    }

} 

5.写业务service(syncSpOriinfoService)，然后启动就ok了


需要注意的地方是，程序第一次启动时，会将任务信息实例化到数据库中，以后修改任务信息必须修改数据库中的任务，直接修改项目中的信息是没有用的。看来以后还得整个项目来维护了.
