监听器、定时器

来源：互联网发布：重庆seo外包服务商编辑：程序博客网时间：2024/05/29 13:18

1. 建立监听类 SalesPaymentListener

package com.eas.kingdee.salespayment.listener;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import com.eas.kingdee.salespayment.runner.SalesPaymentRunnerManager;

/**
*
* @author youzhen_qin
*
*/
public class SalesPaymentListener implements ServletContextListener{

private static WebApplicationContext webApplicationContext;
private static ApplicationContextHelper helper = new ApplicationContextHelper();
@Override
public void contextDestroyed(ServletContextEvent arg0) {

}

@Override
public void contextInitialized(ServletContextEvent arg0) {
  webApplicationContext = WebApplicationContextUtils.getRequiredWebApplicationContext(arg0.getServletContext());
  helper.setApplicationContext(webApplicationContext);

  //run 定时器
  SalesPaymentRunnerManager.initRunner(arg0);
}

}

2. 定时器类

package com.eas.kingdee.salespayment.runner;

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

import javax.servlet.ServletContextEvent;

import org.apache.log4j.Logger;
import org.springframework.context.ApplicationContext;

import com.eas.kingdee.salespayment.listener.ApplicationContextHelper;
import com.eas.kingdee.salespayment.task.SalesPaymentTask;

public class SalesPaymentRunnerManager {
private static final Logger logger = Logger.getLogger(SalesPaymentRunnerManager.class);

public static final void initRunner(ServletContextEvent applicationContext) {
  logger.info("initRunner.");
  ApplicationContextHelper helper = new ApplicationContextHelper();
  final ApplicationContext context = helper.getContext();
  new Thread(){
   public void run() {
    logger.info("saledaily xt push thread started.");
    while(true){
     try {
      long inteval = 1*60L * 60L * 1000L;   //1 小时跑一次
      sleep(inteval);
//      if(betweenTime("19:00:00","23:50:00")){
         if(betweenTime("18:00:00","18:02:00")){
       SalesPaymentTask task = new SalesPaymentTask();
       boolean pushSuccess = task.pushMsg(context);   //具体执行的业务操作
       logger.info("pushSuccess-----："+pushSuccess);
      }

     } catch (Exception e1) {
      logger.error("定时推送通知任务失败", e1);
      return ;
     }
    }
   }

  }.start();
}

public static boolean betweenTime(String beginStr,String endStr) throws ParseException{
  DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
  Calendar cal = Calendar.getInstance();
  //今天
  Date thisTime = cal.getTime();
  String thisStr = format.format(thisTime); //当前时间
   beginStr = thisStr.substring(0,11)+beginStr; //开始时间
   endStr = thisStr.substring(0,11)+endStr; //
  //第二天
  Date beginDate = format.parse(beginStr);
  Date endDate = format.parse(endStr);
  if(thisTime.after(beginDate) && thisTime.before(endDate)){
   return true;
  }else{
   return false;
  }
}

public static final void stopRunner() {

}

}

3. web.xml 配置

<listener>
  <listener-class>
   com.eas.kingdee.salespayment.listener.SalesPaymentListener
  </listener-class>
</listener>
