彻底解决Failed to configure a DataSource: ‘url‘ attribute is not specified and no embedded datasource

错误消息

springboot2启动项目报错，应该是数据库连接的问题，导致无法启动。

错误消息如下：

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

解决方法

不需要连接数据库
