InvokingJobDetailDetailFactory对象：

private String targetObject; // 具体需要执行的计划任务
private String targetMethod; private ApplicationContext ctx;@Override
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {

} public void setTargetObject(String targetObject) {

} public void setTargetMethod(String targetMethod) {

}
}
备注：set方法不能少，setApplicationContext中的applicationContext与factory.setApplicationContextSchedulerContextKey(“applicationContext”)填入的值有关，其原理由InvokingJobDetailDetailFactory父类中的BeanWrapper实现。

quartz集群实现原理，利用数据库记录job行为，并通过锁机制，使job在同一次中仅运行一次。
JobBean示例
//需要交由spring管理
@Service("dialogJob")
public class DialogJob { @Autowired
private QuestionService questionService;
// 方法名在quartz定义
public void execute() throws Exception{
//具体执行业务
questionService.XXXXX();
}}
