檢查了quartz的配置沒什麼問題，可是仍是執行了兩次，很奇怪web

查了不少資料，大多數spring加載quartz的時候加載了兩次spring

寫了下面監聽類也沒有起做用spring-mvc

17     @Override
18     public void contextDestroyed(ServletContextEvent arg0) {
19         WebApplicationContext webApplicationContext = (WebApplicationContext) arg0
20                 .getServletContext()
21                 .getAttribute(

24                 .getBean("personInfoTask");
25         StdScheduler accessRecordTask = (StdScheduler) webApplicationContext
26                 .getBean("accessRecordTask");
27         if(personInfoTask != null) {

29         }
30         if(accessRecordTask != null) {
31             accessRecordTask.shutdown();
32         }
33         try {
34             Thread.sleep(1000);
35         } catch (InterruptedException e) {
36             e.printStackTrace();
37         }
