当文件是参数时，java不能删除它

Question

我会把我的代码放在第一位：

@Post
public Representation post(InputStream zip) throws Throwable {
    createFile(zip, "C:/temp\abc.zip");
    return new StringRepresentation("File uploaded");
}    

public void createFile(InputStream zipStream, uploadedFileLocation) throws Exception {
    try {
        writeToFile(zipStream, uploadedFileLocation);
        FileUtils.forceDelete(new File(uploadedFileLocation));
        } catch (Exception e) {
             throw e;
        }
}


private void writeToFile(InputStream uploadedInputStream, String uploadedFileLocation) {
    try {
        OutputStream out = new FileOutputStream(new File(uploadedFileLocation));
        int read = 0;
        byte[] bytes = new byte[1024];

        out = new FileOutputStream(new File(uploadedFileLocation));
        while ((read = uploadedInputStream.read(bytes)) != -1) {
            out.write(bytes, 0, read);
        }
        out.flush();
        out.close();
        uploadedInputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

我正在尝试制作一个允许用户上传zip文件的服务器。然后服务器将zip文件写入磁盘，解压，然后删除zip，同时将解压部分保留在服务器上。但是，当我将zip文件发送到服务器时，它无法被删除。当使用FileUtils.forceDelete()时，它表示无法删除该文件。这是理想的拉链被删除后，解压缩

编辑：我只能在post(InputStream zip)返回后删除文件。如果我在post方法中调用delete，它不会删除，因为post没有返回。有办法吗
