我试图制作Spring Bookmark tutorial的超简化版本（使用gradle而不是maven）。我的代码可以在这里找到：https://github.com/JetForMe/spring-hoa/tree/master/src/main/java/com/latencyzero/hoa
我所做的更改之一是调用“用户”教程称之为“帐户”的内容，以及我不认为的轻微风格变化导致问题，但它们可能是，如果这是一个名称匹配问题（但我认为Spring非常聪明，可以寻找类型）。
在任何情况下，我的UserRepository类都没有被实例化，因此不能自动连接到我的其余类。仔细阅读教程，我没有看到任何特殊的工作来实例化存储库。
日志显示可能是红色鲱鱼：“Spring Data MongoDB - 无法安全地识别存储库候选接口com.latencyzero.hoa.UserRepository的存储分配。”
这是完整的日志：

知道我忽略了什么吗？谢谢！
答案 0 :(得分：0)
好的，事实证明我错过了一些依赖项。我添加了spring-boot-starter-data-jpa和h2。现在我收到了不同的错误，但我会发布一个关于此问题的新问题。
