title: Why the routes in main config not loaded if you add routes in other config file?
body: <p>I'm setting up a spring cloud gateway application that has 3 environments (DEV, QA, PROD). All main routes are placed on the main config file but I have other routes that need to be declared in the environment config file. Please check the sample config file below:</p>
  
  <p>test.yaml(main)</p>
  
  <pre><code> spring:
    cloud:
      gateway:
        routes:
          - id: test-routes-1
            uri: http://testing1.com/
          - id: test-routes
            uri: http://testing.com/
  </code></pre>
  
  <p>test-dev.yaml</p>
  
  <pre><code> spring:
    cloud:
      gateway:
        routes:
          - id: test-routes
            uri: http://testing-dev.com/
  </code></pre>
  
  <p>When I deploy the application with this config file only the dev routes will be available and the other routes in the main config are not available. How should I fix this?</p>
