报错信息:org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is com.microsoft.sqlserver.jdbc.SQLServerException: 服务器无法继续执行该事务。说明: 8900000003。
xml代码如下:
<task:scheduler id="scheduler" pool-size="5"/> <task:scheduled-tasks scheduler="scheduler"> <!--BOM库龄每间隔1分钟执行--> <task:scheduled ref="amsJob" method="eglInventoryAgingBom" fixed-delay="10000"/> <!--RFID库龄每间隔1分钟执行--> <task:scheduled ref="amsJob" method="eglInventoryAgingRfid" fixed-delay="10000"/> <!-- 日库存,每隔一天执行 --> <task:scheduled ref="amsJob" method="dailyItrn" cron="0 0 1 * * ?"/> </task:scheduled-tasks>
amsJob.java文件代码如下:
@Service public class AmsJob { @Resource private InventoryBomAgingMapper inventoryBomAgingMapper; @Resource private InventoryRfidAgingMapper inventoryRfidAgingMapper; //当在此处添加事务时报错 @Transactional public void eglInventoryAgingBom() { inventoryBomAgingMapper.eglInventoryAgingBom(); } @Transactional public void eglInventoryAgingRfid() { inventoryRfidAgingMapper.eglInventoryAgingRfid(); } }
报错原因:不能为这个事务打开JDBC连接,任务调度每10秒钟执行一次,当执行第一次时,拿到第一次连接,给这个连接加上了Transcational,当第二次再去连接池取时,可能会拿到同一个连接,并且还带上了第一次的Transcational,但是第二次本身有自己的Transcational,因此报错.
解决方案:采取折中的办法,新建一个Service类,在service类中添加事务,amsJob去调用service中的方法.
解决方案代码如下:
amsJob.java文件代码做如下修改:
@Service public class AmsJob { // 在此处注入一个Service,在这个Service里添加事务 @Resource private JobService jobService; //在此处把事务给去掉 public void eglInventoryAgingBom() { jobService.eglInventoryAgingBom(); } public void eglInventoryAgingRfid() { jobService.eglInventoryAgingRfid(); } }
新增JobService类:
@Service public class JobService { @Resource private InventoryBomAgingMapper inventoryBomAgingMapper; @Resource private InventoryRfidAgingMapper inventoryRfidAgingMapper; //事务在此处开启 @Transactional public void eglInventoryAgingBom() { inventoryBomAgingMapper.eglInventoryAgingBom(); } @Transactional public void eglInventoryAgingRfid() { inventoryRfidAgingMapper.eglInventoryAgingRfid(); } }
如此一来,大功告成,皆大欢喜.
