一旦后端微服务得到保护，应用程序就不会启动

Question

我在深度潜水9甚至博客系列第7步中遇到以下错误。只有当我确保后端服务安全时才会出现此问题。 如果我只执行步骤直到approuter，应用程序加载没有任何问题。 你能说出可能是什么原因吗？

此致 阿伦。

Answer 1

在与另一个具有相同症状的用户一起解决此问题之后，我目前的回答是，Spring安全依赖项在受保护的应用程序的pom.xml中互不兼容。例如，使用Spring版本0.28.6进行类加载时，如博客中所述使用依赖项会抛出java.lang.NoClassDefFoundError:org/springframework/core/KotlinDetector，但在0.27。*下它们可以正常工作。

因此，请确保使用博客中描述的依赖项，或者也添加/更新缺少的/其他依赖项。
