quartz 定时任务调度管理器

本项目使用的是spring-quartz

以下配置可以开启多个已知定时任务

MySpringBeanJobFactory:

 1 public class MySpringBeanJobFactory  extends SpringBeanJobFactory {
 2
 3     @Autowired
 4     private AutowireCapableBeanFactory autowireCapableBeanFactory;
 5
 6     @Override

 9         autowireCapableBeanFactory.autowireBean(jobInstance);
10         return jobInstance;
11     }
12 }

MyJob:

1 public class MyJob extends QuartzJobBean {
2
3     private final static Logger logger = LoggerFactory.getLogger(MyJob.class);
4
5     @Override
6     protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
7      //处理自己的业务逻辑
8     }

经测试：定时任务调度器开启的定时任务，当任务状态为：完成（COMPLETE）时，此任务自动回收
