quartz實現定時任務

---

1. pom.xml 引入maven 依賴

<dependency>
  <groupId>org.quartz-scheduler</groupId>
  <artifactId>quartz</artifactId>
  <version>2.2.3</version>
</dependency>

1. pom.xml註冊監聽器
   ps:項目實際實現 ServletContextListener 接口的類的全路徑

<listener>
    <listener-class>xxx.xxx.xxListener</listener-class>
</listener>

1. java 代碼實現（共涉及三個 .java 文件）

   AbcAcountTaskActiveStart.java (創建Schedeler，定義執行規則)
   　　　在線生成cron規則網站： http://cron.qqe2.com/

publlic class AbcAcountTaskActiveStart{
  public void start(){
    try{
        Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
        scheduler.start();
        JobDetail job = JobBuilder.newJob(AbcAountActiveTaskJob.class).withIdentity("tbl_upmgm_day_trade_statistice","spp_day").build();
        String cron = "0 0 0 1-31 * ?"; //每天凌晨執行
        CranTriggrt tigger = newTrigger().withIdentity("dayTrigger","spp_day").withSchedule(cronSchedule(cron)).build();
        scheduler.scheduleJob(job,trigger);
        }catch(Throwable e){
        //日誌打印異常，定時器服務錯誤
        }
    }
}

AbcAountActiveTaskJob.java (實際任務中要執行的代碼)

public class AbcAountActiveTaskJob implements Job {
    public void execute(JobExecutionContext context)throws JobExecutionException{
        //具體要實現的代碼
    }
}

SchedulerListener.java (註冊監聽，全路徑對應web.xml 監聽器路徑)

public class SchedulerListener implements ServletContextListener{
    public void contextDestroyed(ServletContextEvent arg0){
    }
    public void contextInitialized (ServletContextEvent arg0){
        new AbcAcountTaskActiveStart().start();
    }
}

如有錯誤，還望各界大佬不吝賜教！！！
