Add CORS functionality to spring cloud gateway mvc

[manojsinghsaun]

I required cross origin functionality in spring gateway mvc but I am not able to use it E.g This metadata is not present in spring gateway mvc.

spring:
  cloud:
    gateway:
      routes:
      - id: cors_route
        uri: https://example.org
        predicates:
        - Path=/service/**
        metadata:
          cors
            allowedOrigins: '*'
            allowedMethods:
              - GET
              - POST
            allowedHeaders: '*'
            maxAge: 30

Hi @spencergibb Do there will be update in next version release? can you provide some solution or work around for time being? Because I am stuck with this now.

It can be in the next minor, but that will not be until November. In the meantime, you might be able to use normal Spring Boot configuration https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#web.servlet.spring-mvc.cors and https://docs.spring.io/spring-framework/reference/web/webmvc-cors.html
