我有一个Spring云API网关与keycloak服务器进行JWT身份验证。如果我从eclipse运行我的应用程序，并将keycloak作为单个Docker容器，它工作正常。但是，当我将我的Sping Boot 应用程序作为Docker容器运行时（使用Docker compose或kubernetes），它无法使用keycloak进行授权，并引发以下错误。

org.springframework.security.oauth2.jwt.JwtDecoderInitializationException: Failed to lazily resolve the supplied JwtDecoder instance

这种情况是否需要任何其他配置？
