APPLICATION FAILED TO START
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).
参考GPT和自己的思路：
这个错误表明程序启动过程中无法确定适合的驱动程序类。可能的原因是未正确配置数据库连接信息或缺少正确的数据库驱动程序包。
建议您检查以下内容：
检查您的数据库连接配置信息是否正确。
检查您是否正确添加了适合您的数据库的驱动程序包。
如果您正在使用嵌入式数据库（如H2、HSQL或Derby），请确保将其放置在类路径上。
您可以通过使用'--debug'选项重新运行应用程序以显示更详细的调试信息，以获得更精确的解决方案。
希望这些信息能帮到您。
参考GPT和自己的思路：
根据你提供的错误日志，可以看到程序启动失败的原因是无法确定适当的驱动程序类，可能是由于缺少数据库驱动程序或未正确配置数据源所致。你可以采取以下步骤来解决该问题：
1.检查数据库驱动程序是否正确配置。
2.确保您的应用程序具有正确的数据源配置。
3.请在应用程序的类路径下添加适当的数据库驱动程序。
4.如果您使用的是Spring Boot，请检查您的application.properties或application.yml配置文件，确保任何关于数据库的配置正确。
如果你仍然无法解决这个问题，我建议你开启debug模式，查看更多的应用程序启动信息以便能够全面了解问题。
该回答引用GPTᴼᴾᴱᴺᴬᴵ
这个错误提示是无法配置数据源，因为“url”属性未指定且没有嵌入式数据源可配置，因此无法确定适当的驱动程序类。解决此问题，您可以采取以下步骤：
希望这些步骤可以帮助您解决问题。
