Akka http在Java中创建分块实体（从Scala转换）

我正在尝试将以下代码从Scala转换为Java：

    object ChunkedStaticResponse {
        private def createStaticSource(fileName : String) = 
          FileIO
            .fromPath(Paths get fileName)
            .map(p => ChunkStreamPart.apply(p))


        private def createChunkedSource(fileName : String) =
          Chunked(ContentTypes.`text/html(UTF-8)`, createStaticSource(fileName))

        def staticResponse(page:String) =
        HttpResponse(status = StatusCodes.NotFound,
          entity = createChunkedSource(page))
    }

但是我在第二种方法的实现上遇到了麻烦。到目前为止，我已经做到了：

class ChunkedStaticResponseJ {

  private Source<HttpEntity.ChunkStreamPart, CompletionStage<IOResult>> 
     createStaticSource(String fileName) {
     return  FileIO
            .fromPath(Paths.get(fileName))
            .map(p -> HttpEntity.ChunkStreamPart.create(p));
  }

  private HttpEntity.Chunked createChunkedSource(String fileName) {
    return HttpEntities.create(ContentTypes.TEXT_HTML_UTF8, 
           createStaticSource(fileName)); // not working
  }

  public HttpResponse staticResponse(String page)  {
    HttpResponse resp =  HttpResponse.create();
    return resp.withStatus(StatusCodes.NOT_FOUND).withEntity(createChunkedSource(page));
  }
}

类ChunkedStaticResponseJ{
私人来源
createStaticSource（字符串文件名）{
返回文件
.fromPath（路径.get（文件名））
.map（p->HttpEntity.ChunkStreamPart.create（p））；
}
私有HttpEntity.Chunked createChunkedSource（字符串文件名）{
返回HttpEntities.create（ContentTypes.TEXT\u HTML\u UTF8，
createStaticSource（文件名））；//不工作
}
公共HttpResponse静态响应（字符串页）{
HttpResponse resp=HttpResponse.create（）；
返回与状态（未找到状态代码）的响应。与实体（createChunkedSource（第页））的响应；
}
}

我不知道如何在第二种方法中创建分块源。

有人能建议一种方法吗？另外，我的路径是否正确？

如果您只想通过testring从文件中读取的每个

元素创建
块，您可以利用
Chunked.fromData
（
HttpEntities.createChunked
在JavaDSL中）

下面是Scala方面的结果

  object ChunkedStaticResponse {
    private def createChunkedSource(fileName : String) =
      Chunked.fromData(ContentTypes.`text/html(UTF-8)`, FileIO.fromPath(Paths get fileName))

    def staticResponse(page:String) =
      HttpResponse(status = StatusCodes.NotFound,
        entity = createChunkedSource(page))
  }

这就是它的JavaDSL对应物

class ChunkedStaticResponseJ {
    private HttpEntity.Chunked createChunkedSource(String fileName) {
        return HttpEntities.createChunked(ContentTypes.TEXT_HTML_UTF8, FileIO.fromPath(Paths.get(fileName)));
    }

    public HttpResponse staticResponse(String page)  {
        HttpResponse resp =  HttpResponse.create();
        return resp.withStatus(StatusCodes.NOT_FOUND).withEntity(createChunkedSource(page));
    }
}
