1.首先在dispatcher-servlet.xm中引入定时器的配置文件
如：<import resource="quartz/quartz-data.xml"/>
2.定时器中配置文件配置相关信息

<property name="triggers">

</property>
</bean>
</beans>
3.编写需要定时执行的类
package com.fpi.safety.datahandler.common.cache;
import java.util.Map;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.fpi.safety.datahandler.common.cache.model.SmsInfo;
/**清除所有短信缓存*/
public class CleanSmsCash {
private Logger log = LoggerFactory.getLogger(CleanSmsCash.class);
public void execute(){
Map<String,SmsInfo> smsMap = SmsCache.INSTANCE.getAllSmsCache();
if(!smsMap.isEmpty()){
for(String key : smsMap.keySet()){
log.info("-----------------------------------------得到短信缓存的手机号码为--------------------------------"+key);
}
}
SmsCache.INSTANCE.cleanAllSmsCache();
log.info("-----------------------------------------清除了所有短信缓存--------------------------------");
}
}
