服务者–数据源配置报错

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).

解决方法：项目没有加载到yml或者properties文件，特别是自己的pom打包是jar的项目，请查看自己的pom.xml文件中的packaging

jar
如果pom中指定使用jar，系统不会自动读取到yml或者properties文件的，需要我们手动配置pom.xml。
