srping boot （2.2.5） 事务没有起效 事务显示已回滚 事物回滚成功，但是数据表新插入的数据没有变化

Question

表的引擎 inndb 启动类加了 @EnableTransactionManagement
spring boot + mybits +自定义异常处理
a 方法调用b 方法 a,b 方法上都加了 @Transactional 都是public修饰
b方法异常 事物回滚成功，但是数据表新插入的数据没有变化

在异常单处理  手动回滚  报错
  springboot No transaction aspect-managed TransactionStatus in scope



    这是哪里没有配置对吗  事务管理没有效果![自定义异常类](https://img-ask.csdn.net/upload/202005/14/1589438424_157888.png)

Answer 1

启动类上是否开启了事务呢？
