Question

我正在尝试创建一个web服务，只要更新某个文件夹就会发送数据。我使用的是一个接口filelistener。问题是我的接口方法没有执行我的代码是接口方法filechanged未执行

public class SendFile implements FileListener
{
    FileMonitor monitor=new FileMonitor(1000);
    private static String Final;
    private static final String FILE_PATH = "C:\\Users\\298637\\Desktop\\Test1.xml";
    private InputStream is;
    public void Send(String msg)
    {
        Final=msg;
    }
    @GET
    @Path("/get")
    @Produces("application/xml")
    public InputStream getFile() {
    try
    {
        //FileMonitor monitor=new FileMonitor(1000);
        monitor.addFile(new File ("D:/uploaded"));
        monitor.addListener(new Test());
        System.out.println(Final);
        is = new FileInputStream(FILE_PATH);
        ResponseBuilder response = Response.ok((Object) is);
        response.header("Content-Disposition","attachment; filename=newfile.xml");
        //while(!false);
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
    return is;
    }

    class Test implements FileListener
    {
    public void fileChanged (File file)
    {
        System.out.println ("File changed: " + file);
        monitor.Receive(file);
    }
    }
}

为了得到结果，任何人都可以告诉我应该改变什么
