I followed the docs at https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto-two-datasources and created my source code accordingly.我按照https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto-two-datasources的文档并相应地创建了我的源代码。 When I start up the application I receive this error message:当我启动应用程序时，我收到此错误消息：

APPLICATION FAILED TO START应用程序无法启动

Description:描述：

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.无法配置数据源：未指定“url”属性，并且无法配置嵌入式数据源。

Reason: Failed to determine suitable jdbc url原因：无法确定合适的 jdbc url

Action: Consider the following: If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.行动：考虑以下几点：如果您想要一个嵌入式数据库（H2、HSQL 或 Derby），请将其放在类路径中。 If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).如果您有要从特定配置文件加载的数据库设置，您可能需要激活它（当前没有配置文件处于活动状态）。

I searched for similar issues and only found that one: Error access two datasource with Spring Boot我搜索了类似的问题，只发现一个： Error access two datasource with Spring Boot

The solution for this was contained in the error message but (at least for me) a little bit too hidden.解决方案包含在错误消息中，但（至少对我而言）有点太隐藏了。

I forgot to add the h2 jar so the real reason wasn't that Spring Boot couldn't determine suitable jdbc url but more the missing driver. I forgot to add the h2 jar so the real reason wasn't that Spring Boot couldn't determine suitable jdbc url but more the missing driver.
