Spring boot 启动错误处理

今天准备把我之前搭建的，基于springboot的框架的基础功能包抽离出来，在增加spring yml自定义设置后，在业务项目启动时会报出以下异常。

Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (the profiles "dev,redis,config,mongodb,activemq,socketio" are currently active).

在多方查证后，需要在启动类的@EnableAutoConfiguration或@SpringBootApplication中添加exclude = {DataSourceAutoConfiguration.class}，排除此类的autoconfig。启动以后就可以正常运行。 
后期在继续抽取spring boot底层功能封装时，会从源码找到此问题发生的原因，并更新此文章
