标签：work jdbc 文件 服务 问题 开启 pre lse inventory 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: amsJob.java文件代码如下: 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: 新增JobService类: 如此一来,大功告成,皆大欢喜. spring添加@Transcational的事务调度问题 标签：work jdbc 文件 服务 问题 开启 pre lse inventory 原文地址：https://www.cnblogs.com/icanner/p/9725195.html task:scheduler id="scheduler" pool-size="5"/>
