Spring的定制任务

今天碰到个问题，需要达到一个功能，使服务器定时执行某一个事件，后来想到了使用spring定制任务。

 

下面是配置  spring

<bean id="synNbrAccountTask" class="com.zlinfo.util.AddUserLogTimer" >      <!-- 这里是你要执行的事件 -->
  <property name="userService" ref="userService"></property>       <!--  这里是注入的service -->
  <property name="userLogService" ref="userLogService"></property>      
 </bean>
      
    <bean id="synNbrAccountTaskInfo" class="org.springframework.scheduling.timer.ScheduledTimerTask" >
      
          <property name="delay">
                <value>5000</value>      <!--  这里是延迟多少秒执行 -->
          </property>
        
          <property name="period">
                <value>43200000</value>    <!-- 86400000为24小时 -->      <!--这里是间隔多长事件执行一次事件
          </property>
        
          <property name="timerTask">
                <ref local="synNbrAccountTask"/>
          </property>
    </bean>

    <bean id="timerBean" class="org.springframework.scheduling.timer.TimerFactoryBean" >
          <property name="scheduledTimerTasks" >
                <ref bean="synNbrAccountTaskInfo" />
          </property>
    </bean>

 

下面是我自己要执行的事件,这个类一定要继承TimerTask,重写run方法

package com.zlinfo.util;

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import java.util.TimerTask;

import com.zlinfo.dao.UserDao;
import com.zlinfo.dao.impl.UserDaoImpl;
import com.zlinfo.model.User;
import com.zlinfo.model.UserLog;
import com.zlinfo.service.UserLogService;
import com.zlinfo.service.UserService;

/**
 * 定义定时器 每天的17点添加所有员工的日志主表
 * 
 * @author Administrator
 * 
 */
public class AddUserLogTimer extends TimerTask {
 private UserLogService userLogService;
 
 private UserService userService;

 public UserLogService getUserLogService() {
  return userLogService;
 }

 public void setUserLogService(UserLogService userLogService) {
  this.userLogService = userLogService;
 }

 public UserService getUserService() {
  return userService;
 }

 public void setUserService(UserService userService) {
  this.userService = userService;
 }

 @Override
 public void run() {
  //先检查今天的数据是否插入
  DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
  List<UserLog> checkUserLogs = userLogService.userLogList(new UserLog());
  boolean falg = false;
  for(UserLog ul : checkUserLogs){
   //如果UserLog表中插入了今天的数据，则不用再进行插入
   if(df.format(ul.getLogTime()).equals(df.format(new Date()))){
    falg = true;
   }
  }
  if(!falg){
   User user = new User();
         List<User> users = userService.list(user);         
   for (User u : users) {
    UserLog ul = new UserLog();
    String time = df.format(new Date());
    try {
     ul.setLogTime(df.parse(time));
    } catch (ParseException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }
    ul.setLogUserName(u.getName());
    ul.setLogUserId(u.getId());
    ul.setLogDept(u.getDept_name());
    ul.setLogAssess("正常");
    userLogService.insert(ul);
    System.out.println("添加了一个用户");
   }
  }
 }

}
