Question

Aurelia（确切地说是aurelia-dependency-injection）是否支持将多个成员注入数组（如multi inject feature of InversifyJS）？

示例：

提供商-common.ts：

class A { ... }

provider1.ts

let a1 = new A (...)
container.registerInstance(A, a1)

provider2.ts

let a2 = new A (...)
container.registerInstance(A, a2)

consumer.ts

@inject(A)
class B {
  constructor (multipleAInstancesFromDiffirentProviders :Array<A>) {
      // I would expect multipleAInstancesFromDiffirentProviders to contain [a1,a2] (if such a feature is supported)
  }
}

Answer 1

您可以尝试使用All.of(A)：

    import {inject, All} from "aurelia-framework";

    @inject(All.of(A))
    class B {
        constructor (multipleAInstancesFromDiffirentProviders :Array<A>) {
        }
    }

Answer 2

最好的方法是使用All.of(A)。

您也可以使用此选项：

import { Container } from 'aurelia-framework';

@inject(Container)
class B {
    constructor (container: Container) {
      var multipleAInstancesFromDifferentProviders : Array<A> = container.getAll(A);
    }
}
