您可以在运行时@Inject吗？

Question

我需要在运行时动态加载类，例如psuedocode：

@Injectable()
export class MyService {
  withGettable(serviceName: IGettableServices) {
    return @Inject(serviceName)service.get()
  }
}

我该怎么做？

Answer 1

在页面底部的injector中查看一些示例。

@Injectable()
export class MyService {

  constructor(private injector: Injector) {}

  withGettable(serviceName: IGettableServices) {
    // retrieves an instance from the injector based on the provided token.
    return this.injector.get(serviceName);
  }
}
