这是前台前台展示页面(smartGwt)：

//生日提醒

Timer timer=new Timer(){

public void run(){

mainService.Timing(null,new AsyncCallback(){

public void onFailure(Throwable caught) {

}

public void onSuccess(Object result) {

String str=(String)result;

Date day=new Date();

int today=day.getHours();

String strc=today+"";

if(!str.trim().equals("")&&strc.equals("9"))

SC.say("今天是 "+str+" 的生日");

}

});

}

};

timer.scheduleRepeating(1000*3600*1); //每隔1小时运行一次

timer.run();

这是后太的service(grails+java):

//定时提醒

public String Timing(List lists){

/**

Timer time=new Timer();

//设定 当天的9点 提醒生日

Calendar data=Calendar.getInstance();

//data.set(Calendar.HOUR,13);

// data.set(Calendar.MINUTE,0);

//data.set(Calendar.SECOND,15);

MyTimingService myTiming=new MyTimingService();

if(lists.equals(null))

{time.schedule(myTiming,1000*15,10*1000);

return null;

}

else

{

String str=null;

for(int i=0;i

UserArchives ua=lists.get(i);

User u=User.findById(ua.getUser().getId());

str +=u.getName();

}

System.out.println(str);

return str;

}*/

String str="";

System.out.println("运行生日提醒方法了");

List BirthList=UserArchives.findAll( " from UserArchives where MONTH(dateOfBirth)=MONTH(CurDATE()) AND DAY(dateOfBirth)=DAY(CurDATE())");

for(int i=0;i

UserArchives ua=BirthList.get(i);

User u=User.findById(ua.getUser().getId());

str +=u.getName()+" ,";

}

return str;

}

这个是开始写的 代码 发现没有办法传到前台 后来就放弃了：

package com.tservice.XZRS;

import java.util.List;

import com.tservice.XZRS.RealService;

import javax.servlet.http.HttpSession;

import org.springframework.web.context.request.RequestContextHolder;

class MyTimingService extends TimerTask{

String userName;

static transactional = true

public void run() {

System.out.println("运行生日提醒方法了");

List BirthList=UserArchives.findAll( " from UserArchives where MONTH(dateOfBirth)=MONTH(CurDATE()) AND DAY(dateOfBirth)=DAY(CurDATE())");

System.out.println(BirthList.size());

if(BirthList.size()!=0)

{

System.out.println("11111");

RealService real=new RealService();

real.Timing(BirthList);

}

}

}
