看到上面的add页面中有上传的路径，那就说明在页面上添加完视频后就要提交的，那下面就是controller中接口的实现。

首先是yml文件中配置：
# 项目相关配置 ruoyi:# 名称name: RuoYi# 版本version: 4.0.0# 版权年份copyrightYear: 2019# 实例演示开关demoEnabled: true# 文件路径 示例（ Windows配置D:/ruoyi/uploadPath，Linux配置 /home/ruoyi/uploadPath）profile: D:/ruoyi/uploadPath ## 获取ip地址开关addressEnabled: true你可以看到prifile就是视频在页面中保存文件夹路径映射，在页面中展示视频要这样：http://**.**.**.**:8080/profile/****.mp4这样才是播放视频，接下来是映射配置在config中，先在全局参数设置中定义路径名称，从yml配置中可以方便取出，
package com.ruoyi.common.config;import java.io.FileNotFoundException; import java.util.HashMap; import java.util.Map; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import com.ruoyi.common.utils.StringUtils; import com.ruoyi.common.utils.YamlUtil;/*** 全局配置类* * @author 于留俊*/ public class Global {private static final Logger log = LoggerFactory.getLogger(Global.class);private static String NAME = "application.yml";/*** 当前对象实例*/private static Global global;/*** 保存全局属性值*/private static Map<String, String> map = new HashMap<String, String>();private Global(){}/*** 静态工厂方法*/public static synchronized Global getInstance(){if (global == null){global = new Global();}return global;}/*** 获取配置*/public static String getConfig(String key){String value = map.get(key);if (value == null){Map<?, ?> yamlMap = null;try{yamlMap = YamlUtil.loadYaml(NAME);value = String.valueOf(YamlUtil.getProperty(yamlMap, key));map.put(key, value != null ? value : StringUtils.EMPTY);}catch (FileNotFoundException e){log.error("获取全局配置异常 {}", key);}}return value;}/*** 获取项目名称*/public static String getName(){return StringUtils.nvl(getConfig("ruoyi.name"), "RuoYi");}/*** 获取项目版本*/public static String getVersion(){return StringUtils.nvl(getConfig("ruoyi.version"), "4.0.0");}/*** 获取版权年份*/public static String getCopyrightYear(){return StringUtils.nvl(getConfig("ruoyi.copyrightYear"), "2019");}/*** 实例演示开关*/public static String isDemoEnabled(){return StringUtils.nvl(getConfig("ruoyi.demoEnabled"), "true");}/*** 获取ip地址开关*/public static Boolean isAddressEnabled(){return Boolean.valueOf(getConfig("ruoyi.addressEnabled"));}/*** 获取文件上传路径*/public static String getProfile(){return getConfig("ruoyi.profile");}/*** 获取头像上传路径*/public static String getAvatarPath(){return getProfile() + "/avatar";}/*** 获取下载路径*/public static String getDownloadPath(){return getProfile() + "/download/";}/*** 获取上传路径*/public static String getUploadPath(){return getProfile() + "/upload";} }这个通用配置，用过的朋友，肯定知道这是配置文件，接口文档等的配置。

Constants是个工具类，配置全局参数的，贴出来
package com.ruoyi.common.constant;/*** 通用常量信息* * @author 于留俊*/ public class Constants {/*** UTF-8 字符集*/public static final String UTF8 = "UTF-8";/*** 通用成功标识*/public static final String SUCCESS = "0";/*** 通用失败标识*/public static final String FAIL = "1";/*** 登录成功*/public static final String LOGIN_SUCCESS = "Success";/*** 注销*/public static final String LOGOUT = "Logout";/*** 登录失败*/public static final String LOGIN_FAIL = "Error";/*** 自动去除表前缀*/public static final String AUTO_REOMVE_PRE = "true";/*** 当前记录起始索引*/public static final String PAGE_NUM = "pageNum";/*** 每页显示记录数*/public static final String PAGE_SIZE = "pageSize";/*** 排序列*/public static final String ORDER_BY_COLUMN = "orderByColumn";/*** 排序的方向 "desc" 或者 "asc".*/public static final String IS_ASC = "isAsc";/*** 资源映射路径 前缀*/public static final String RESOURCE_PREFIX = "/profile"; }还有这里需要在ShiroConfig中配置一下profile不需要验证，我把配置文件贴出，你可以加入项目试一下，好用！
