分析服务器

　　无法通过腾讯云点播服务器得到提交作品封面信息，那么需要自己去做一个服务器去专门上传封面信息

　　腾讯云点播服务器提供视频发布，自己做的服务器去上传封面信息

　　自己搭建的SSH服务器上传视频封面

完成文件的上传

　　我们从本地获得图片资源后，在服务器下没有该路径，那么就在其中创建一个空的File文件，将获得的的图片以二进制流保存到服务器的File中

　　将视频页面上传至服务器逻辑

        //文件保存到项目
        //文件保存位置
        String path = ServletActionContext.getServletContext().getRealPath("/images");
        //创建一个file文件
        File file = new File(path);
        //路径如果不存在，要手动make一下
        if(!file.exists())
        {

解决文件服务器Bug--上传相同重复的文件

　　Web层对提交相同文件进行处理

    public String addFile() throws Exception {
        
//        System.out.println(upload);
//        System.out.println(uploadContentType);
//        System.out.println(uploadFileName);
        
        //保存到数据库
        
        //文件保存到项目
        //文件保存位置
        String path = ServletActionContext.getServletContext().getRealPath("/images");
        //创建一个file文件
        File file = new File(path);
        //路径如果不存在，要手动make一下
        if(!file.exists())
        {
            file.mkdir();
        }
        //文件拷贝的格式
        FileUtils.copyFile(upload, new File(file,uploadFileName));
        System.out.println(path);
        
        //保存到数据库
        Lfile lfile = new Lfile();
        lfile.setFilename(uploadFileName);
        lfile.setFiletype(uploadContentType);
        lfile.setUrl(path+"\"+uploadFileName);
        
        Date date = new Date(System.currentTimeMillis());
        SimpleDateFormat  format = new SimpleDateFormat("yyyy-MM-dd");
        String createtime = format.format(date);
        
        lfile.setCreatetime(createtime);
        
        //判断数据库中是否存在相同名字的文件
        boolean success =fileService.JudgeLfilename(uploadFileName);
        //如果有相同的filename我们就不进行插入
        if(success) {
            fileService.addFile(lfile);
        }
        
        
        return "default";
    }

　　Service层逻辑：判断数据库中是否有重复的数据，如果数量大于1那么则不能再往服务器中添加数据，反之可添加数据

    public boolean JudgeLfilename(String uploadFileName) {
        int num = fileDao.JudgeLfilename(uploadFileName);
        //如果num>0证明数据库中存在相同的文件名称
        if(num>0)
        {
            return false;
        }else {
            return true;
        }

    }

　　Dao层对数据库的查询处理

    public int JudgeLfilename(String uploadFileName) {
        Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();
        String sql = "select count(*) from lfile where filename = ?";
        NativeQuery query = session.createSQLQuery(sql);
        query.setParameter(1, uploadFileName);
        BigInteger result = (BigInteger) query.uniqueResult();
        
        return result.intValue();
    }

跨两个服务器请求

　　一个是8080端口shakes项目，一个是8081端口Fileio项目

　　不带数据的跨域请求

　　带数据的跨域请求

            <input type="text" name="test">

　　上传文件的ajax跨域请求

                建议整曲和剪辑版本（如副歌部分）一起提交，30s-60s的剪辑版本更适合抖音拍摄和传播哦
                <br>
                歌曲的剪辑版本建议命名为歌名-剪辑版，更方便被推荐~
