双重跨域：Access-Allow-Origin header contains multiple values“*, *”,but only one is allowed

问题：前端调试发现接口响应头中存在两个Access-Allow-Origin ，但是后端通过apifox或者postman调试都无法重新问题。
原因：后台在网关（spring cloud gateway）开启跨域后，在服务中也拦截了特定路径进行跨域。wtf。

spring:
   cloud:    
    gateway:
    	#解决双重跨域
      default-filters:
        - DedupeResponseHeader=Access-Control-Allow-Origin Access-Control-Allow-Credentials,
      globalcors:
          cors-configurations:
             '[/**]':
             allowed-origins: "*"
             allowed-methods: "*"
             allowed-headers: "x-requested-with,Content-Language,Authorization,Access-Control-Allow-Origin,request-id,Accept-Language,content-type,content-disposition"
             allow-credentials: true
