ArkTS 有可用的依赖注入框架吗 (HarmonyOS 鸿蒙Next)

可以利用Reflect实现反射和注解机的功能，Demo实现如下：

// 定义 MyPropertyDecorator 装饰器函数，使用 Reflect.defineMetadata 进行属性注解
function MyPropertyDecorator(target: Object, propertyKey: PropertyKey): void {
  const metadataKey = `myProperty_${String(propertyKey)}`;
  Reflect.set(target, propertyKey, metadataKey, "This is a custom annotation")
}
// 定义一个类，并在其中使用装饰器进行注解
class MyClass {
  @MyPropertyDecorator
  myProperty: string = "Hello, World!";
}

@Entry
@Component
struct DependencyInjectionDemo {
  @State message: string = 'Hello World';

  build() {
    RelativeContainer() {
      Button(this.message)
        .id('DependencyInjectionDemoHelloWorld')
        .fontSize(50)
        .fontWeight(FontWeight.Bold)
        .alignRules({
          center: { anchor: '__container__', align: VerticalAlign.Center },
          middle: { anchor: '__container__', align: HorizontalAlign.Center }
        })
        .onClick(() => {
          const annotation = Reflect.get(new MyClass(), "myProperty");
          console.log(annotation)
        })
    }
    .height('100%')
    .width('100%')
  }
}
