我正在尝试运行一个与 keycloak 集成的示例应用程序（用于 IAM）。构建成功，但是在运行应用程序时，出现以下错误...

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

我添加了 com.fasterxml.jackson.core(2.9.5) 和 com.fasterxml(1.3.1) 作为依赖项。Springboot 版本是 - 2.0.3.RELEASE

fastxml 依赖项是否存在版本兼容性问题？如何找到缺少的依赖项并解决这个问题？

您需要添加 hibernate-validator 依赖项，它附带了 com.fasterxml:classmate 捆绑在其中。

<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>7.0.1.Final</version>
</dependency>
