Symfony2 routing.yml的评论 - 怎么做？

This is the routing in my Symfony2 App (part of routing.yml):

app_my_responses_response:
    path: /author/response/{responseId}/comments/{page}
    defaults: { _controller: AppBundle:Response:view, page: 1 }
    methods: [GET]
    requirements:
        responseId: \d+

Objective of this route – execute on next cases (

1. /author/response/8293085 { page:1 }
2. /author/response/8293085/ { page:1 }
3. /author/response/8293085/comments/ { page:1 }
4. /author/response/8293085/comments/1/ { page:1 }
5. /author/response/8293085/comments/2/ { page:2 }

I have problems with urls numbered 1 and 3...and I don't know what to do...

The best way to solve this problem is remove requirements and create another route for 1st and 3th pattern. It works for me. Thanks @kba!
