请问在前后端分离项目只配置了jwt令牌，启动报错是什么原因

我创建项目时是2.6.1sprinboot，我手动改成2.3

Error starting Tomcat context. Exception: org.springframework.beans.factory.UnsatisfiedDependencyException. Message: Error creating bean with name 'securityConfig': Unsatisfied dependency expressed through field 'restAuthorizationEntryPoint'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.xxxx.server.config.security.RestAuthorizationEntryPoint' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

这个错误应该是jar包之间的版本不兼容哦。
