Java 从Synyx Hades迁移到Spring数据JPA

我想从Hades迁移到Spring Data JPA（我知道，已经很晚了）。但是，当我在配置中使用

@EnableJpaRepositories

注释来启用它时，会出现以下异常：

由于我不是最有经验的Spring用户，我甚至不知道从哪里开始调试，Google也没有返回任何信息。如果我在某个地方显式地自动连接一个

环境

，我会得到一个，所以我不知道为什么它会在这里为空

---

我做错了什么？如何修复它？

因此修复相当简单：将所有Spring组件的版本修复到3.2.9后，一切都正常工作

---

我相当肯定这是由于（多亏了对问题的评论）。

对于初学者来说，修复您的依赖性，您正在混合使用spring 3.2.3和3.2.6 JAR。不要混用JAR的版本。你能添加环境代码吗？@paul Environment是；-）。以前从未使用过，如果是这样的话，也许你可以看看这张票。你愿意试用Spring3.2.9吗？这可能是您出现异常的原因。当然，正如@M.Deinum所说的，不要混用不同的版本。
