spring框架下注解事务出现的异常
我在用注解事务的时候出现下面的异常
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [beans.xml]: BeanPostProcessor before instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/aopalliance/aop/Advice
