angular 5 中的循环依赖错误

Question

我总是收到循环依赖的警告

WARNING in Circular dependency detected:
src\app\auth\logout\logout.component.ts -> src\app\auth\_services\authentication.service.ts -> src\app\app.module.ts -> src\app\app-routing.module.ts ->
src\app\auth\logout\logout.component.ts

WARNING in Circular dependency detected:
src\app\theme\layouts\header-nav\header-nav.component.ts -> src\app\_services\data\emp.service.ts -> src\app\app.module.ts -> src\app\theme\layouts\layout.module.ts -> src\app\theme\layouts\header-nav\header-nav.component.ts

WARNING in Circular dependency detected:
src\app\theme\layouts\layout.module.ts -> src\app\theme\layouts\header-nav\header-nav.component.ts -> src\app\_services\data\emp.service.ts -> src\app\app.module.ts -> src\app\theme\layouts\layout.module.ts

WARNING in Circular dependency detected:

我用了这个然后就解决了

"build": {
      "showCircularDependencies": false
    },

但是如何在不使用 "showCircularDependencies": false

的情况下解决这个问题

Answer 1

我想这是没有办法解决的。您可能可以通过将其中一个 services 分解为新的 service 并小心地包含它们来避免这种情况。

看看Single Responsibility Principle。这是规避此类问题的可靠方法。
