我在BITGoogleBundle中有一项服务，它依赖于路由器服务来生成特定的回调路由：
BIT\GoogleBundle\Google\GoogleClient::setUp
如果我在构造函数中调用此方法，则会出现此错误：
ServiceCircularReferenceException: Circular reference detected for service
"security.context", path: "profiler_listener -> profiler -> security.context ->
security.authentication.manager -> bit_google.client -> routing.loader ->
assetic.asset_manager -> twig".
但如果我把它称为其他服务的正常功能，那就可以了。
这是什么方法来避免这个错误？

所有这一切都是我在github上的回购中称为GoogleBundle的一部分，在那里你可以找到所有的代码，但上面的那个有问题的
