【问题描述】：
数小时以来，我一直在通过堆栈溢出中的许多位置调查此错误，但未能找到解决方案。我在 Udemy 上，从初学者到大师春季靴子课程。当我尝试运行它所说的代码时，我目前遇到了一个问题。

Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
这是我遇到此问题的 github 存储库的链接。 https://github.com/jeffhennen/spring5webapp
我尝试了许多不同的事情来解决这个问题。我尝试了也收到错误的教授代码。我试图将 java 版本更改为许多不同的类型，从 java 8、11（教授将其作为他们的 JDK）、17（这是我为我的 springboot 创建和使用的）。
我尝试了以下方法：
- 我安装了 jdk 17，我安装了 JDK 11 并卸载了 JDK 17
- 调整了POM中的java版本
- 根据其他堆栈溢出问题调整了依赖关系。
- 将
"management.health.defaults.enabled=false"添加到应用程序属性。 - 没有使用Mysql所以不知道如何调整数据库信息
- 尝试将@springbootapplication 更改为
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })，但这导致了错误
