将 spring 引导版本升级到 2.6.6 时出错

Question

我正在将我的 spring 引导应用程序升级到最新的稳定版本 2.6.6，构建成功，但运行时出现以下错误。我如何查看缺少此 class PropertySourceLocator 的原因，以及通常有人可以采取哪些步骤来解决与我的案例中的依赖项相关的此类问题。我尝试了各种方法，比如排除任何冲突的依赖关系，使用不同库的兼容版本，如 spring-boot 和 spring cloud.

你对那个 class 有依赖性吗？

<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-context -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-context</artifactId>
    <version>3.1.0</version>
</dependency>
