问题描述
从昨天开始，在全新安装后，我们的Spring Boot项目出现问题，而没有更改Maven文件，lib或其他内容的配置.
Since yesterday we have a problem on our spring boot project after clean install without change nothing of configuration of the maven files, libs or something else.
我们确实尝试将SpringFrameWork和Spring引导的pom版本更新为1.5.4.Release.
We did try to update version of pom's of SpringFrameWork and Spring boot to 1.5.4.Release.
显示的错误是:

推荐答案
根据 ConfigurationPropertySources源，该类来自2.0.0版
According to ConfigurationPropertySources source, this class is around from version 2.0.0
您可能没有升级Spring Boot版本，但实际上降级了.
You probably did not upgrade your spring boot version but actually downgrade.
