本文介绍了无法确定用于测试的嵌入式数据库.如果你想要一个嵌入式数据库，请在类路径上放置一个受支持的数据库的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用 spring 框架开发应用程序，但遇到了无法解决的问题.我正在尝试运行我的集成测试以确保我的数据库和我的应用程序之间的通信运行良好，但我遇到了运行时异常.
I am working on an application using spring framework and I have run into a problem that I have been unable get past.I am trying to run my integration tests to ensure communication between my database and my application works quite well but I am running into a runtime exception.

我得到以下异常.我最初认为这是由于我的依赖项中没有一些 jar 文件，但在添加了一些依赖项后，我没有想法
And I get the following exception. I initially thought this was due to not having some jar files present in my dependency but after adding some dependencies, I am out of ideas

推荐答案
所以为了完整起见，我意识到我尝试针对的是嵌入式系统进行测试，而这不是我的意图.我必须包含 @AutoConfigureTestDatabase 才能使其工作.
So for completeness, I realized what I was trying to test against was an embedded system and that wasn't my intent. I had to include @AutoConfigureTestDatabase for it to work.
