百度UEditor 上传组件 使用虚拟路径映射配置

com.baidu.ueditor.upload.BinaryUploader 类的修改源码后，有报错的情况

具体方法是save方法第77行
boolean virtualPath = (boolean)conf.get("virtualPath");
这行报错，说是Object不能转为boolean

public static final State save(HttpServletRequest request,
Map conf) {
//using PathFormat
savePath = PathFormat.parse(savePath, originFileName);

        boolean virtualPath = (boolean)conf.get("virtualPath");

        String physicalPath = (String) conf.get("rootPath") + savePath;
        //启用虚拟路径时，不再使用 rootPath
        if(virtualPath)
        {
            //此时savePath已含有实际的映射物理路径
            physicalPath = savePath;//no rootPath
        }
        log.debug("file physicalPath:" + physicalPath);

        InputStream is = fileStream.openStream();
        State storageState = StorageManager.saveFileByInputStream(is,
                physicalPath, maxSize);
        is.close();

}

改为((Boolean)xxx).booleanvalue
