问题
我在控制台中收到以下错误：

是 org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: 无法确定合适的驱动程序类

描述：
无法配置数据源：未指定 'url' 属性，且无法配置嵌入式数据源。
原因：无法确定合适的驱动程序类
操作：
考虑以下内容：
如果您想要使用嵌入式数据库（H2、HSQL 或 Derby），请将其放置在类路径中。
如果您有要从特定配置文件加载的数据库设置，可能需要激活它（当前未激活任何配置文件）。

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).

得分: 4
以下是要翻译的内容：
你能否请尝试在你的 application.properties 文件中使用以下属性。
spring.datasource.driver-class-name=org.postgresql.Driver
英文:
Could you please try the below property in you application.properties file.
spring.datasource.driver-class-name=org.postgresql.Driver
