Question

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.

Caused by: java.lang.NoClassDefFoundError: com/fasterxml/classmate/TypeResolver

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

是否存在带有fastxml依赖项的版本兼容性问题？如何找到缺少的依赖关系并解决这个问题？

Answer 1

您需要添加 hibernate-validator 依赖项，它与捆绑在其中的 com.fasterxml:classmate 一起提供。

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