我有一个Spring Web应用程序,配置为使用JDK代理AOP. AOP注释(例如@Transactional)在接口上声明,而不是实现类.

应用程序本身工作正常,但是当我运行单元测试时,似乎试图使用CGLIB作为AOP功能(而不是JDK代理).这导致测试失败 – 我在下面附加了堆栈跟踪.

我不明白为什么在运行测试时使用CGLIB,因为Spring配置与应用程序运行时基本相同.一个可能的显着区别是测试配置使用DataSourceTransactionManager而不是JTA事务管理器.测试类本身都延伸到AbstractJUnit4SpringContextTests,这个类是不是以某种方式硬连线使用CGLIB？

编辑：其中一位评论员要求我发布Spring配置.我以缩写形式列出了它(即不相关的bean和XML名称空间省略).

为spring-servlet.xml
