Description

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

Contributor guide

Research direction
Examine the existing CORS support in the WebFlux based Spring Cloud Gateway and understand how metadata based CORS configuration is handled. Investigate how to adapt this for the MVC variant, potentially by creating a custom filter or modifying the route definition handling.
