Scheduler 工厂分别是 org.quartz.impl.DirectSchedulerFactory 和 org.quartz.impl.StdSchedulerFactory

DirectSchedulerFactory 是为精细化控制 Scheduler 实例产生的工厂类,一般不用，不过有利于理解quartz内部组件。

-- 最简单
public void createScheduler(ThreadPool threadPool, JobStore jobStore);
-- 最复杂
public void createScheduler(String schedulerName, String schedulerInstanceId,ThreadPool threadPool, JobStore jobStore, String rmiRegistryHost, int rmiRegistryPort);

 public scheduler createScheduler(){
	 DirectSchedulerFactory factory=DirectSchedulerFactory.getInstance();
	 try {
	 	//创建线程池
	 	SimpleThreadPool threadPool = new SimpleThreadPool(10, Thread.NORM_PRIORITY);
	 	threadPool.initialize();
		//创建job存储类
	 	JobStoreTX jdbcJobStore = new JobStoreTX();
	 	jdbcJobStore.setDataSource("someDatasource");
 		jdbcJobStore.setPostgresStyleBlobs(true);
 		jdbcJobStore.setTablePrefix("QRTZ_");
 		jdbcJobStore.setInstanceId("My Instance");
		
		logger.info("Scheduler starting up...");
		factory.createScheduler(threadPool,jdbcJobStore);
		// Get a scheduler from the factory
 		Scheduler scheduler = factory.getScheduler();

		// 必须启动scheduler
 		scheduler.start();
 		return scheduler;
 	}
 		return null;
 }

org.quartz.impl.StdSchedulerFactory 依赖于属性类(Properties)决定如何生产 Scheduler 实例

通过加载属性文件,Properties 提供启动参数:

public scheduler createScheduler(){
 	// Create an instance of the factory
 	StdSchedulerFactory factory = new StdSchedulerFactory();
	
	// Create the properties to configure the factory
 	Properties props = new Properties();
 	// required to supply threadpool class and num of threads
 	props.put(StdSchedulerFactory.PROP_THREAD_POOL_CLASS,"org.quartz.simpl.SimpleThreadPool");
 	props.put("org.quartz.threadPool.threadCount", "10");
	
	try {
 		// Initialize the factory with properties
 		factory.initialize(props);
		Scheduler scheduler = factory.getScheduler();
		logger.info("Scheduler starting up...");
 		scheduler.start();
	} catch (SchedulerException ex) {
		logger.error(ex);
	}
}
