`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 (the profiles local are currently active).`

问题原因：

原因是数据源没有指定，不知道url要执行哪里，应该是我们的pom.xml文件中导入了依赖但是却没有指定数据源导致的.
正常应该是要配置的如下信息的
