php - Symfony 在调试 :container --show-private 中不显示私有(private)服务

Question

运行

app/console debug:container --show-private 

不列出使用 public: false 声明的服务，例如:

 another_service:
        public: false
        class: MineBundle\Service\FirstService

但是，如果我运行 app/console debug:container --show-private | wc -l 和 app/console debug:container | wc -l 我会得到不同的结果。

尝试使用 symfony 2.8 和 3.1 并得到相同的行为。

有什么想法吗？

谢谢!

Sorry, it's in the doc :)

If a private service is only used as an argument to just one other service, it won't be displayed by the debug:container command, even when using the --show-private option. See Inline Private Services for more details.

然后

What makes private services special is that, if they are only injected once, they are converted from services to inlined instantiations (e.g. new PrivateThing()). This increases the container's performance.
