Spring Boot 升级 2.4.5 到 2.5 问题 : NPE springSecurityFilterChain

转载作者：行者123 更新时间：2023-12-03 18:47:27

我在从 SpringBoot 2.4.5 升级到 2.5.0 时遇到了一些问题。项目为Kotlin项目，同样使用13.0.0版本的Keycloak作为IDM。
错误发生在应用程序启动和测试时。异常在 ConfigServletWebServerApplicationContext 内抛出留言 Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springSecurityFilterChain' defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.servlet.Filter]: Factory method 'springSecurityFilterChain' threw exception; nested exception is java.lang.NullPointerException您也可以查看 SecurityConfig.kt , SecurityConfigTest.kt以及以下两个堆栈跟踪(应用程序和测试的正常启动):

升级在应用程序启动时产生以下错误:
