大佬教程收集整理的这篇文章主要介绍了在 Spring Boot 应用程序中创建名为“requestMappingHandlerAdapter”的 bean 时出错，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我在一个简单的测试项目中使用带有 Thymeleaf 的 Spring Boot 应用程序。我想在用户登录时显示一条消息，所以我想使用 sec:authorize="isAuthenticated()"。我创建了我的配置类（这对我来说是全新的），但出现错误
org.springframework.beans.factory.beanCreationException: Error creaTing bean with name 'requestMapPingHandlerAdapter' defined in class path resource [org/springframework/web/servlet/config/Annotation/DelegaTingWebMvcConfiguration.class]: Bean instantiation via factory method Failed; nested exception is org.springframework.beans.beanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.Annotation.requestMapPingHandlerAdapter]: Factory method 'requestMapPingHandlerAdapter' threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/security/web/method/Annotation/CurrentSecurityContextArgumentResolver
