达梦数据库兼容1.5.2版本seata,本地Java项目启动后，所有的spring自带事务注解都失效了，导致正常的保存都不行

本地用了Jpa来做jdbc框架，jpa框架所有方法上的@Transactional注解都失效了，报的错误是javax.persistence.TransactionRequiredException: no transaction is in progress

No source files or tests are named. Start by reproducing the local JPA setup with Seata 1.5.2 and the Dameng database, then trace why the Spring @Transactional methods reach javax.persistence.TransactionRequiredException. Done means the affected transaction annotations work for normal saves and the failure is covered by a relevant regression test.
