Java Spring单元测试未从数据库获取更新的值

我使用普通SpringJDBC和dao进行了简单的spring配置。 我已经为dao层添加了一个测试用例，它实现了以下功能。 -获取设置 -测试记录的数量和值 -使用新值更新设置 -测试更新的值

我无法使用更新的断言值，下面是我得到的错误。不知道怎么了

Spring将在您使用时回滚DB更新：

defaultRollback=true

---

根据我对“defaultRollback=true”的理解，测试框架将回滚每个测试方法的所有事务。在我的例子中，使用我正在执行的测试方法获取记录（settingsDaoImpl.getSettings（）），更新记录（settingsDaoImpl.saveSetting（settings）），然后再次获取记录的值（settingsDaoImpl.getSettings（）），我的测试期望在最后一次获取时更新值，但我们仍然获取旧值。任何想法。谢谢你的帮助。顺便说一句，我试过使用“defaultRollback=false”，但是没有用。有人能帮我吗？我做错了什么？我回答，因为我无法评论。我建议您参考以下链接：-我觉得您遇到了某种异常，请在调用数据库查询时放置try-catch块。尝试深入查看堆栈跟踪，您将找到解决方案。
