springMVC配置定時任務使用案例

定時任務常常是資料統計必不可少的任務處理方法,這裡介紹的是quartz定時任務外掛的配置和使用案例,使用場景是定時給餘額不足的使用者傳送簡訊通知;關於簡訊通知的設計和實現如下:
1.在applicationContext.xml配置載入定時任務觸發器的spring-quartz.xml配置,如:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd"> <!-- 資原始檔 --> <!-- 引入配置 --> <bean class="com./.prop.EncryptProperty"> <property name="locations"> <list> <value>classpath:config/cloud.properties</value> </list> </property> </bean> <bean id="appContext" lazy-init="false" class="com./.spring.AppContext"/> <!-- 匯入其他模組的配置 --> <import resource="classpath:spring/*.xml"/> <bean class="com./.cms.util.SysCodeUtil"></bean> <bean class="com./.cms.util.SysThirdUserUtil"></bean> <bean class="com./.cms.util.ConfigParamUtil"></bean> </beans>
2.在 spring-quartz.xml中配置定時任務的掃描路徑及其觸發器引數配置:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd"> <!-- 定時任務掃描路徑 --> <context:component-scan base-package="com./.cms.quartz"/> <task:executor id="executor" pool-size="5"/> <task:scheduler id="scheduler" pool-size="10"/> <task:annotation-driven executor="executor" scheduler="scheduler"/> </beans>
3.對應的com./.cms.quartz包下的任務例項如下:
package com./.cms.quartz; import com./.cms.bo.DriverAccountBO; import com./.cms.dao.DriverAccountDao; import com./.cms.service.DriverAccountIsEnoughService; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.scheduling.annotation.Scheduled; import org.springframework.stereotype.Component; import org.springframework.transaction.annotation.Transactional; import javax.annotation.Resource; import java.util.List; /** * @author chengaofeng5 * @Description:賬戶餘額是否足額(不小於0)狀態更新定時任務 * @date 2018年10月17日 15:27 */ @Component @Transactional public class DriverAccountIsEnoughTask { private final Logger log = LoggerFactory .getLogger(DriverAccountIsEnoughTask.class); /** CPU核心數 */ private int cpuCoreNum = 4; @Autowired private DriverAccountDao dao; @Resource private DriverAccountIsEnoughService service; /** * @Description: 定義定時任務每天0點2分執行一次,查詢要更新狀態的賬戶 * @author * @date 2018年10月17日 17:16:01 * */ //@Scheduled(cron = "0 0/2 * * * ?") @Scheduled(cron = "0 2 0 ? * *") public void updateDriverAmountStatus() { log.info("DriverAccountIsEnoughTask updateDriverAmountStatus begin..."); try { // 查詢待更新的記錄併發簡訊 List<DriverAccountBO> accountList = dao.selectUpdateList(); if (!accountList.isEmpty()) { service.sendMethods(accountList); // 簡訊通知成功,更新正常->欠費的狀態 dao.updateAmountStatus1(); } // 更新欠費->正常的狀態 dao.updateAmountStatus0(); } catch (Exception e) { log.error("賬戶餘額狀態定時任務更新異常", e); } log.info("DriverAccountIsEnoughTask updateDriverAmountStatus end..."); } }
4.service處理簡訊邏輯為:如果amount<=0且amount_status=0的記錄傳送簡訊,否則amount>0且amount_status=1的記錄更新狀態,其中 `amount_status` tinyint(3) unsigned NOT NULL DEFAULT '0' COMMENT '賬戶餘額狀態: 0 正常(賬戶餘額不小於0) 1欠費',`amount` int(11) NOT NULL COMMENT '賬戶餘額:單位分';處理程式碼如下:
/**
* @author
* @Description:賬戶餘額是否充足實時更新方法
* @date 2018年10月18日 10:53
*/
@Service
public class DriverAccountIsEnoughServiceImpl implements
DriverAccountIsEnoughService {
protected static final Logger log = Logger
.getLogger(DriverAccountIsEnoughServiceImpl.class);
// 賬戶餘額狀態: 0 正常(賬戶餘額不小於0) 1欠費
private final static byte amount_status_0 = (byte) 0;
private final static byte amount_status_1 = (byte) 1;
/**
* @Description: 批量處理所有的賬戶記錄
* @author
* @date
* @param accountList
* @return
*
*/
@Override
public void sendMethods(List<DriverAccountBO> accountList) {
// 判斷記錄條件傳送簡訊
for (DriverAccountBO da : accountList) {
// 傳送簡訊條件為:amount<=0且amount_status=0的記錄(此判斷可去掉,在查詢的時候已處理),且不為免傳送簡訊的手機號
Boolean isSend = ((da.getAmount() <= 0 && da.getAmountStatus()
.equals(amount_status_0)))
&& null != da.getMobilePhone()
&& !da.getMobilePhone().equals(
SysCodeUtil.getString("ignoreMobilePhone"));
if (isSend) {
// 發放簡訊方法
this.sendSubmial(da.getMobilePhone());
}
}
}
}
其中,傳送簡訊的記錄查出來,即dao層selectUpdateList方法其查詢語句如下:
<!--查詢所有待簡訊通知的賬戶記錄-->
<select id="selectUpdateList" resultType="com.hikvision.cms.bo.DriverAccountBO">
<![CDATA[
SELECT DISTINCT
a.account_id, a.driver_id, a.user_id, a.amount, a.create_time, a.amount_status,
b.mobile_phone
FROM driver_account a
LEFT JOIN sys_user b ON b.user_id=a.user_id
WHERE amount <= 0 AND amount_status = 0
]]>
</select>
簡訊通知成功,更新正常->欠費的狀態updateAmountStatus1方法sql為:
<!--更新使用者賬戶記錄為1的狀態-->
<update id="updateAmountStatus1">
<![CDATA[
update driver_account
set amount_status = 1
where amount <= 0 AND amount_status = 0
]]>
</update>
更新欠費->正常狀態的updateAmountStatus0方法sql為:
<!--更新使用者賬戶記錄為0的狀態-->
<update id="updateAmountStatus0">
<![CDATA[
update driver_account
set amount_status = 0
where amount > 0 AND amount_status = 1
]]>
</update>
至此,定時任務傳送簡訊的功能編碼邏輯結束...哈哈哈,是不是很簡單?
