Springboot + hibernate 运行正常，打成jar包后启动报错：Failed to configure a DataSource

***************************
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).

解决办法：

修改pom.xml，将下图中标红的删除即可。

附上完整的pom.xml
