Description:
Parameter 0 of method modifyRequestBodyGatewayFilterFactory in org.springframework.cloud.gateway.config.GatewayAutoConfiguration required a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' that could not be found.
Action:
Consider defining a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' in your configuration.你遇到的情况有可能和我稍有不同
问题描述ISSUES : https://github.com/spring-cloud/spring-cloud-gateway/issues/478
官方解答ISSUES : https://github.com/spring-cloud/spring-cloud-security/issues/141
简单来说是 Spring Security 和 Spring Cloud Gateway 不兼容的问题.
此处有新版本解决方案实例 : https://github.com/artemMartynenko/spring-cloud-gateway-oauth3-sso-sample-application
题外话
开源框架的版本真是永远也追不上,不要盲目追求新版本
最优的技术是能稳定支撑自己业务的技术,而不是最新的技术.
