pilipili在线视频网站开发日志(二)

今天在进行文件上传逻辑的编写

在jsp页面加上了enctype="multipart/form-data"

            <form action="doUpload" method="post" enctype="multipart/form-data">
                <div class="form-group fg1" style="margin-top: 30px; ">
                    <input type="file" name="video" value="上传视频" style="position:absolute;opacity: 0;">
                    <span>选择上传视频  <i class="icon-download-alt icon-2x"></i></span>
                </div>

                <div class="form-group">
                    <input type="text" placeholder="视频标题" name="title">
                </div>
                <div class="form-group">
                    <input type="text" placeholder="给你的视频一点表述吧" name="desc">
                </div>
                <div class="form-group">
                    <select name="type" id="category_name" >
                        <option value="">选择类型</option>
                        <option value="animation">动漫</option>
                        <option value="dance">舞蹈</option>
                        <option value="game">游戏</option>
                        <option value="ghost">鬼畜</option>
                        <option value="movie">电影</option>
                    </select>
                </div>

                <div class="form-group">
                    <input type="submit" value="投稿">
                </div>

            </form>

在controller里，写了@RequestParam("video") MultipartFile file

    @PostMapping("doUpload")
    public String doUpload(HttpSession session, HttpServletRequest request, @RequestParam("video") MultipartFile file){
        //, @RequestParam("video") MultipartFile file, Video video, String title, String desc, String category_name
        Logger logger = LoggerFactory.getLogger(UserController.class);
        String fileUrl = file.getOriginalFilename();
        Video media = new Video();
        media.setName(request.getParameter("title"));
        media.setDesc(request.getParameter("desc"));
        logger.info("视频名称为：" + media.getName() + " 视频描述为：" + media.getDesc() + " 视频类型为：" + request.getParameter("type"));
        logger.info(fileUrl);
        return "upload";

在springmvc中，写了bean标签

    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 设定默认编码 -->
        <property name="defaultEncoding" value="UTF-8"></property>
        <!-- 设定文件上传的最大值5MB，5*1024*1024 -->
        <property name="maxUploadSize" value="99999999"></property>
    </bean>

可是！！！仍然报错

后来发现！

居然是pom文件内没有导入所需要的包！！！！

    <dependency>
      <groupId>commons-fileupload</groupId>
      <artifactId>commons-fileupload</artifactId>
      <version>1.3.2</version>
    </dependency>

    <!-- Apache Commons IO -->
    <dependency>
      <groupId>commons-io</groupId>
      <artifactId>commons-io</artifactId>
      <version>2.5</version>
    </dependency>

一定要导入啊啊啊啊！！！
