我对春靴很陌生。因此，在从spring引导项目之后，我试图在intellij上运行它。但是我在启动它的时候出错了。

以下是版本的

Java :8

弹簧-启动: 2.0.6

我试过更改spring的引导版本，但没有帮助。

还更改了application.properties中的服务器端口，但这也没有帮助。

pom.xml

   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).

由于尚未向此项目添加任何数据库，因此从data-jpa文件中删除pom.xml依赖项，

这造成了依赖冲突。

一旦移除，它将正常运行。

要解决这个问题，您可以做两件事：

  1. 从pom.xml中删除数据源依赖项。
  2. 第二种是可以在application.properties中配置数据源。

就像下面..。

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
