推荐答案
不仅要根据要求在注释中提供答案，还必须提供;-)
To give this an answer not only in comments as requested ;-)
要从拦截器中排除某些服务(甚至是用于不同组件的相同服务)，最好将您的应用程序拆分为模块，并仅在需要时才在模块中提供拦截器.例如，登录后或在管理区域内.
To exclude some services (or even the same services used in different components) from an interceptor it's best to split your application into modules and provide the interceptor only in modules where it's needed. For example after logging in or inside of an admin area.
甚至可以使用@Component声明的providers属性为单个组件提供拦截器.
The interceptor may be even provided for single components using the @Component declaration's providers property.
