Spring的定时器

今日看到blaiu的关于Spring的定时器，故转载过来详细研究下。
applicationContext.xml：

<!-- 定时器的实验开始 -->
<bean id="comrepeatingTrigger"
class="org.springframework.scheduling.timer.ScheduledTimerTask">

<!--启动一秒后执行 -->
<property name="delay">
<value>61000</value>
</property>

<!--每分钟执行一次 -->
<property name="period">
<value>60000</value>
</property>

<!--注入要监控的javaBean -->
<property name="timerTask">
<ref bean="companyTask" />
</property>


<!--类型是否为fixedRate型，默认为fixedDelay-->
<property name="fixedRate">
<value>true</value>
</property>
</bean>
<!--
<bean id="scheduler"
class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="scheduledTimerTasks">
<list>
<ref bean="comrepeatingTrigger" />
</list>
</property>
</bean>
-->

<bean id="companyTask" class="com.here.web.common.CompanySampleTask">
<property name="hereProductService">
<ref bean="hereProductService"/>
</property>
<property name="areaChangeUtil">
<ref bean="areaChangeUtil"/>
</property>
<property name="hereUserService">
<ref bean="hereUserService"/>
</property>
<property name="hereCorporationService">
<ref bean="hereCorporationService"/>
</property>
</bean>
<!-- 定时器的实验结束 -->

用法：

public class CompanySampleTask extends TimerTask{
private HereProductService hereProductService;
private AreaChangeUtil areaChangeUtil;
private HereUserService hereUserService;
private HereCorporationService hereCorporationService;
private SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss");

//----------------------------------产品接口
public HereProductService getHereProductService() {
return hereProductService;
}
public void setHereProductService(HereProductService hereProductService) {
this.hereProductService = hereProductService;
}

//----------------------------------地区接口
public AreaChangeUtil getAreaChangeUtil() {
return areaChangeUtil;
}
public void setAreaChangeUtil(AreaChangeUtil areaChangeUtil) {
this.areaChangeUtil = areaChangeUtil;
}

//----------------------------------用户接口
public HereUserService getHereUserService() {
return hereUserService;
}
public void setHereUserService(HereUserService hereUserService) {
this.hereUserService = hereUserService;
}

//----------------------------------企业接口
public HereCorporationService getHereCorporationService() {
return hereCorporationService;
}
public void setHereCorporationService(
HereCorporationService hereCorporationService) {
this.hereCorporationService = hereCorporationService;
}

public void run() {
String HQL = "from HereUser hereUser";
List hereUsers = this.hereUserService.queryByHQL(HQL);
if(hereUsers.size()>0) {
for(int i=0; i<hereUsers.size(); i++) {
HereUser hereUser = (HereUser)hereUsers.get(i);
HereCorporation hereCorporation = this.hereCorporationService.queryById(hereUser.getUserId(), HereCorporation.class);
System.out.println("重新生成静态页面CompanySampleTask，时间：" + formatter.format(new Date()));
new CompanyHtmlUtil().buildCompanyHtml(hereUser, hereCorporation, areaChangeUtil, hereProductService);

//System.out.println("重新刷新一下产品列表中的类别信息！，时间：" + formatter.format(new Date()));
//classRelatedTempUtil.setClassRelatedMap();
}
}

}
