java - Springboot“无法访问org.springframework.web.webapplicationinitializer”

Question

我正在使用IntelliJ IDE 2017.2。在eclipse 2020-6中创建的外部导入项目中工作。
当我加载我的Maven依赖项时，IDE指示尽管已在代码之前导入，但仍无法解析依赖项，就像我们在下图中看到的那样：



这是pom.xml：

当我尝试使用IntelliJ环境运行项目时，这引发了以下异常：

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).

知道为什么会发生这种情况以及如何解决吗？

这可能是一个intellij问题。
