从单个文件读取并在多线程中同时将其写入多个文件

Question

我的目的是同步上传主要位置的文件，同时异步上载多个辅助位置上的同一文件。那么请你帮我实现辅助位置写入的多线程（例如同一个文件在读取时同时写多个路径）

以下是从输入流中读取的代码

List<FileUploadMultiLocator> fileUploadList = new ArrayList<>();
FileUploadMultiLocator fum1 = new FileUploadMultiLocator("fileserver0", new BufferedOutputStream(new FileOutputStream(new File(reposMap.get("D:\\Harisingh\\FileUpload\\Destination1.txt")))));    
FileUploadMultiLocator fum2 = new FileUploadMultiLocator("fileserver0", new BufferedOutputStream(new FileOutputStream(new File(reposMap.get("D:\\Harisingh\\FileUpload\\Destination2.txt")))));

fileUploadList.add(fum1);
fileUploadList.add(fum2);

while((len=channel.read(byteBuffer))>=0) 
                {
                    itrCount++;
                    totalBytes+=len;
                    baOS.write(byteBuffer.array(),0,len);
                    if(itrCount>=maxIterateCnt)
                    {
                        //primary location writing
                        bFout.write(baOS.toByteArray(),0,totalBytes);
                        // this is for secondary location writing
                        for (FileUploadMultiLocator fileUploadMultiLocator : fileUploadList) {
                            fileUploadMultiLocator.baOS = baOS;
                            fileUploadMultiLocator.totalBytes = totalBytes;
                            new Thread(fileUploadMultiLocator).start();
                        }
                        totalBytes=0;
                        baOS.reset();
                        itrCount=0;
                    }
                    byteBuffer.clear();
                }

这是我的runnable类，可以同时写多个BufferedOutputStream

public class FileUploadMultiLocator实现Runnable {

public FileUploadMultiLocator(String fileserver,BufferedOutputStream bFout) {
    // TODO Auto-generated constructor stub
    this.fileserver = fileserver;
    this.bFout = bFout;
}
@Override
public void run() {
    // TODO Auto-generated method stub
    try 
    {
        bFout.write(baOS.toByteArray(),0,totalBytes);
        bFout.flush();

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

}
