Quartz 1.8.5 集群（jboss4.2.3 ）

在数据库中创建Quartz所需表（sql语句可以在quartz-1.8.5\docs\dbTables中找到,

       这里以oracle数据库为例）：

qrtz_blob_triggers,

qrtz_calendars,

qrtz_cron_triggers,

qrtz_fired_triggers,

qrtz_job_details,

qrtz_job_listeners,

qrtz_locks,

qrtz_paused_trigger_grps,

qrtz_scheduler_state,

qrtz_simple_triggers,

qrtz_triggers,

        qrtz_trigger_listeners

 

      

加入quartz 所需要的包(放入jboss-4.2.3.GA\server\all\lib下)：

 先把jboss自带的quartz jar删除掉。包括(quartz-ra.rar)都删除掉。

 

commons-dbcp-1.3.jar

commons-pool-1.5.4.jar

jta-1.1.jar

log4j-1.2.14.jar

quartz-all-1.8.5.jar

slf4j-api-1.6.0.jar

        slf4j-log4j12-1.6.0.jar

3.创建quartz-service.xml文件(放入jboss-4.2.3.GA\server\all\deploy下)，文件内容如下：

 <?xml version="1.0" encoding="UTF-8"?>

<server>

  <mbean code="org.quartz.ee.jmx.jboss.QuartzService"

      name="user:service=QuartzService,name=QuartzService">

         <attribute name="JndiName">Quartz</attribute>

         <attribute name="StartScheduler">true</attribute>

<attribute name="Properties">

#============================================================================

# Configure Main Scheduler Properties

#============================================================================

         #==========集群名称,每个节点的名字都一样===========

         org.quartz.scheduler.instanceName = quartzjbossdemopartitionName

         #==========集群每个节点ID=======

org.quartz.scheduler.instanceId = AUTO

 

#============================================================================

# Configure ThreadPool

#============================================================================

         #=======线程====

         org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool

         org.quartz.threadPool.threadCount = 25

         org.quartz.threadPool.threadPriority = 5

 

#============================================================================

# Configure JobStore

#============================================================================

 

      org.quartz.jobStore.misfireThreshold = 60000

      org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX

org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.oracle.OracleDelegate

      org.quartz.jobStore.dataSource = QUARTZ

      org.quartz.jobStore.tablePrefix = QRTZ_

 

      org.quartz.jobStore.isClustered = true

      org.quartz.jobStore.clusterCheckinInterval = 30000

 

#============================================================================

# Configure Datasources

#============================================================================

                   #=================数据库写上自己的数据库======

         org.quartz.dataSource.QUARTZ.driver = oracle.jdbc.driver.OracleDriver

         org.quartz.dataSource.QUARTZ.URL = jdbc:oracle:thin:@192.168.111.24:1521:db         org.quartz.dataSource.QUARTZ.user = rootmq

         org.quartz.dataSource.QUARTZ.password = rootmq

         org.quartz.dataSource.QUARTZ.maxConnections = 5

         org.quartz.dataSource.QUARTZ.validationQuery=select 0 from dual

        

</attribute>

  </mbean>

 

</server>

4.       java 代码

每一个 Quartz Job 必须有一个实现了 org.quartz.Job 接口的具体类.

public class JbossJob implements Job {

 

public void execute(JobExecutionContext arg0) throws JobExecutionException {

    System.out.println("hello jbossJob .....");

}

 

}

5.   具体调用

 public class StartOrCloseScheduler implements Serializable{

 

 

    /**

     *

     */

    private static final long serialVersionUID = -2266323478579408291L;

    private static Logger myLogger = Logger.getLogger(StartOrCloseScheduler.class);

    private static Scheduler sched = null;

    /**

     * 启动任务

     * jobName: job名称

     * jobGroupName: job组名称

     * triggerName: trigger名称

     * triggerGroupName:trigger组名称

     */

    @SuppressWarnings("rawtypes")

    public static void start(String jobName,String jobGroupName,

            String triggerName,String triggerGroupName,

            Class c, String str) {

       try {

           InitialContext ctx = new InitialContext();

            sched = (Scheduler) ctx.lookup("Quartz");

            System.out.println("Scheduler:" + sched);

       } catch (NamingException e) {

           e.printStackTrace();

       }

        JobDetail job = new JobDetail(jobName,jobGroupName, c);

        System.out.println("JobDetail:" + job);

         Trigger trigger = new CronTrigger(triggerName,triggerGroupName);

         System.out.println("Trigger:" + trigger);

    try {

        ((CronTrigger) trigger).setCronExpression(str);

           sched.scheduleJob(job, trigger);

           System.out.println("job:" + job);

           sched.start();

       } catch (Exception e) {

           myLogger.error("开启一个任务"+jobName+e.getMessage());

           e.printStackTrace();

       }

 

    }

 

 

    /**

     * @param jobName: job名称

     * @param jobGroupName: job组名称

     * @param triggerName: trigger名称

     */

    public static void removeJob(String jobName,String jobGroupName,

                                 String triggerName,String triggerGroupName) {

    try {

           InitialContext ctx = new InitialContext();

            sched = (Scheduler) ctx.lookup("Quartz");

       } catch (NamingException e) {

           e.printStackTrace();

       }

    try {

           //停止触发器

           sched.pauseTrigger(triggerName,triggerGroupName);

           //移除触发器

           sched.unscheduleJob(triggerName,triggerGroupName);

           //删除任务

           sched.deleteJob(jobName,jobGroupName);

       } catch (SchedulerException e) {

           myLogger.info("移除一个任务"+jobName+e.getMessage());

       }

    }

 

}
