该代码实现了一个用于上传文件的Java线程UploadFileThread，它使用HTTPURLConnection进行POST请求，支持multipart/form-data格式，处理参数和文件的提交。在上传过程中，对网络连接超时、读取超时进行了设置，并处理了输入输出流，最后根据响应码处理返回数据。
protected class UploadFileThread extends java.lang.Thread {
    private final java.util.Map<String, String> parameterMap;
    private final java.util.Map<String, String> fileMap;

    public UploadFileThread(Map<String, String> parameterMap, Map<String, String> fileMap) {
        this.parameterMap = parameterMap;
        this.fileMap = fileMap;
    }

    @Override
    public void run() {

        try {
            java.net.URL url = new java.net.URL(MHttpUrl.UPLOAD_EXCEL);
            java.net.URLConnection urlConnection = url.openConnection();
            httpURLConnection = (java.net.HttpURLConnection) urlConnection;
            httpURLConnection.setConnectTimeout(10000);
