Spring boot 启动tomcat上下文时发生Spring启动错误。创建名为'；ServletEndpointRegistrator'；

我不熟悉弹簧靴。因此，在从spring Initializer启动一个项目后，我尝试在intellij上运行它。但我在启动时出错了

以下是版本：
爪哇：8
弹簧靴：2.0.6
我尝试过更改spring boot版本，但没有效果。
还更改了application.properties中的服务器端口，但这也没有帮助

   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).

说明：
配置数据源失败：未指定“url”属性，无法配置嵌入式数据源。
原因：无法确定合适的驱动程序类别
行动：
考虑以下事项：
如果您想要一个嵌入式数据库（H2、HSQL或Derby），请将其放在类路径上。
如果要从特定配置文件加载数据库设置，则可能需要激活它（当前没有激活的配置文件）。
