项目名称：magnet

所属系列：OHOS的第三方组件适配移植

功能：

一个适用于鸿蒙的java注解框架

项目移植状态：完全移植

调用差异：基本没有使用差异，可以参照单元测试或原项目api

原项目Doc地址：https://github.com/beworker/magnet

编程语言：java

安装教程

方案一

建议下载开源代码并参照demo引入相关库：

//核心引入
  implementation project(':magnet')
  annotationProcessor project(':magnet-processor')


方案二

项目根目录的build.gradle中的repositories添加：
mavenCentral()

module目录的build.gralde中dependencies添加：
implementation 'com.gitee.ts_ohos:magnet:1.0.0'
annotationProcessor 'com.gitee.ts_ohos:magnet-processor:1.0.0'1.

使用教程

Scope rootScope = Magnet.createRootScope();
Scope playerScope  = rootScope.createSubscope();
playerScope.bind(Uri.class, Uri.parse("https://my-media-file"));
   
// mark 1
MediaPlayer player = playerScope.getSingle(MediaPlayer.class);
player.playWhenReady();
   
// mark 2
Thread.sleep(5000)
playerScope.dispose()
   
// mark 3

// MediaPlayer.java
public interface MediaPlayer {
    void playWhenReady();
}

// DefaultMediaPlayer.java
@Instance(type = MediaPlayer.class, disposer = "dispose")
public class DefaultMediaPlayer implements MediaPlayer{

    private Uri assetId;
    private MediaLoader mediaLoader;

    public DefaultMediaPlayer(Uri assetId, MediaLoader mediaLoader) {
        this.assetId = assetId;
        this.mediaLoader = mediaLoader;
    }


    @Override
    public void playWhenReady() {
        System.out.println("play when ready " + assetId.toString());
    }

    public void dispose() {
        System.out.println("play dispose");
    }
}

// MediaLoader.java
public interface MediaLoader {
    String load(Uri mediaUri);
}

// DefaultMediaLoader.java
@Instance(type = MediaLoader.class)
public class DefaultMediaLoader implements MediaLoader {

    @Override
    public Uri load(Uri mediaUri) {
        return mediaUri;
    }
