我可以定义在学说中调用事件侦听器/订阅者的顺序吗? [英] Can I define the order in which event listeners / subscribers are called in doctrine?

问题描述

我有两个事件订阅者 A 和 B.都订阅了 onFlush 事件.

I have two event subscribers A and B. Both subscribed to the onFlush event.

我想确保 a::onFlush() 总是在 B::onFlush() 之前被调用.我在文档中找不到任何相关资源.

I want to make sure that a::onFlush() is always called before B::onFlush(). I can't find any resource on this in the documentation.

我使用 symfony2，所以如果我能在服务定义中传递值就好了.

I use symfony2 so it would be great if I could just pass the value in in the service definition.

推荐答案

为您的服务标签添加优先级.优先级越高，运行越早.

Add a priority to your service tag. The higher the priority the earlier it will run.

services:
    my.listener:
        class: AcmeSearchBundleEventListenerSearchIndexer
        tags:
            - { name: doctrine.event_listener, event: postPersist, priority: 100 }
