我在 spring boot 中有一个带有 oauth2 的小项目，我想运行资源服务器

设置：

• 爪哇17
• spring-boot-starter-parent 版本 2.5.6
• spring-cloud-dependency 版本 2020.0.4
• spring-boot-starter-oauth2-资源服务器
• spring-security-oauth2-自动配置

当我想运行我的应用程序时，我有例外：

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: Cannot invoke "java.lang.reflect.Method.invoke(Object, Object[])" because "com.sun.xml.bind.v2.runtime.reflect.opt.Injector.defineClass" is null
