spring-boot - NoClassDefFoundError : ConfigurationPropertySources

Question

从昨天开始，我们的 spring boot 项目在全新安装后出现问题，没有更改任何 maven 文件、库或其他配置的配置。

我们确实尝试将 SpringFrameWork 和 Spring boot 的 pom 版本更新到 1.5.4.Release。

显示的错误是:

根据 ConfigurationPropertySources source , 这个类是从 2.0.0 版本开始的

Provides access to {@link ConfigurationPropertySource ConfigurationPropertySources}. @author Phillip Webb
@since 2.0.0

您可能没有升级您的 spring boot 版本，而是实际上降级了。
