Symfony2 kernel.response执行控制器注释后的事件

Question

In order to modify a response cache control header I use a kernel.response event. But when my listener gets called the controllers @cache annotation is not yet executed. How can I make sure that my listener gets called after all controller annotations are executed?

You can change the order of listeners on the same event by setting priority. As you can see in the HttpCacheListener of the SensioFrameworkExtraBundle, there is no explicit priority set. That means it has the default priority of 0 . So you can set your priority to any number higher than 0 (I recommend 10 or the like) to execute it before:

services:
    my_cache_listener:
        class: ...
        tags:
            - { name: kernel.event_listener, event: kernel.response, priority: 10 }
