由于我从Spring 3.2.6迁移到Spring 4.1.2，因此我的测试不起作用。
我发现AnnotationTransactionAspect（TransactionAspectSupport）现在将PlatformTransactionManager缓存在transactionManagerCache字段中。
我使用MockHttpServletRequest来模拟端到端测试。
我的测试不是交易性的，也不会回滚。
我的测试使用@DirtiesContext。在Spring关闭旧上下文并创建一个新上下文之后，将重新创建除AnnotationTransactionAspect之外的所有bean。不重新创建AnnotationTransactionAspect并包含先前测试的缓存。这意味着它包含缓存的PlatformTransactionManager。因此，当在服务层内调用@Transactional方法时，它会尝试从缓存的事务管理器获取数据库连接，但缓存的事务管理器具有已关闭的数据源。当Spring在第一次测试后关闭Application上下文时它被关闭了。
所以我的问题是为什么AnnotationTransactionAspect没有重新创建？
更新添加例外
