下午好,

我在Bean验证器(JSR 303)中注入服务时遇到问题.我将执行验证,但我需要在我的数据库中验证此记录;

当我使用我的服务时,它会抛出NullPointerException;

例外:

我正在使用Spring Boot Cloud + OAuth2 Auth系统,但我在auth方法中遇到了问题.当我尝试使用我的服务器进行身份验证时,Zuul网关没有发送标头参数,但如果我尝试直接向我的oauth服务器进行身份验证,我就没有问题.只有当我尝试通过Zuul网关进行身份验证时,才会出现此问题.

验证回复:

error_description:"访问此资源需要完全身份验证"

使用Zuul请求进行OAuth服务器日志记录:
