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).


Process finished with exit code 1

这个bug是我在写黑马程序员的品达通用权限的时候遇到的，意思是：

配置数据源失败:'url’属性未指定，无法配置任何嵌入的数据源。

原因是没有拉取到nacos里的配置文件导致运行失败
找到父maven发现实我的命名控件id忘了修改（dev环境下的）

找到nacos的命名空间修改一下就可以了


运行成功！
