采用SSM框架技术，其中涉及模块，根据网上一些博客因个人项目而整理开发，可作为他人开发参考
本人开发参考：https://zoutao.blog.csdn.net/article/details/81747046

1、处理工具类及配置文件

（1）配置文件serviceconfig.properties

本地目录文件，Linux环境可更换配置

#临时的视频存储路径，转码完成后删除
TEMPORARY_VIDEO_PATH=D:/zhongjianjian/temp/
#转码成功mp4视频存放路径
TRANSCODE_VIDEO_MP4PATH=D:/zhongjianjian/finshvideo/
#转码ffmpeg.exe工具路径
FFMPEG_PATH=D:/zhongjianjian/tools/ffmpeg.exe
#转码mencoder.exe工具路径
MENCODER_PATH=D:/zhongjianjian/tools/mencoder.exe
#视频截图存放路径
filePath=D:/zhongjianjian/views/static/

（2）加载静态资源服务类

ResourceService.java 方便用于加载配置文件 serviceconfig.properties 中的变量

package com.sslt.utils;import java.util.Enumeration;
import java.util.ResourceBundle;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;/*** 加载静态资源服务* @author **/
public class ResourceService {private final static Logger logger = LoggerFactory.getLogger(ResourceService.class);/** 参数配置文件  */public static ResourceBundle rb = null;/*** 项目启动系统所需配置文件，仅此一次*/static{rb = ResourceBundle.getBundle("serviceconfig");}public static void refresh() {logger.info("开始重载serviceconfig配置文件......");ResourceBundle.clearCache();rb = ResourceBundle.getBundle("serviceconfig");logger.info("检查serviceconfig文件是否重载完成......");Enumeration<String> keys = rb.getKeys();while(keys.hasMoreElements()){String key = keys.nextElement();String value = rb.getString(key);logger.info("serviceconfig配制已经重载--> "+key + " : " + value);}logger.info("serviceconfig配制文件重载完成!");}
}

（3）自定义响应类

ResultBean.java 作为统一响应数据格式

package com.sslt.common;/*** 自定义响应结构*/
public class ResultBean {// 响应业务状态private Integer status;// 响应消息private String msg;// 响应中的数据private Object data;public static ResultBean build(Integer status, String msg, Object data) {return new ResultBean(status, msg, data);}public static ResultBean success(Object data) {return new ResultBean(data);}public static ResultBean success() {return new ResultBean(null);}public ResultBean() {}public static ResultBean build(Integer status, String msg) {return new ResultBean(status, msg, null);}public ResultBean(Integer status, String msg, Object data) {this.status = status;this.msg = msg;this.data = data;}public ResultBean(Object data) {this.status = 200;this.msg = "SUCCESS";this.data = data;}public Integer getStatus() {return status;}public void setStatus(Integer status) {this.status = status;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}public Object getData() {return data;}public void setData(Object data) {this.data = data;}}

响应码工具类 GlobalState.java，可配置统一静态变量

package com.sslt.common;/*** 静态变量工具类* @author MINI**/
public class GlobalState {public static final Integer RESULTSTATUS = 200;           // 默认返回成功状态码public static final Integer FAILSTATUS = 401;             // 失败状态public static final Integer PASTSTATUS = 400;             // 过期状态}

（4）文件校验类

FileUploadToolUtil.java 检测文件类型包括图片和视频格式，检测文件格式是否支持、大小和不能为空

package com.sslt.utils;import java.io.File;
import java.text.DecimalFormat;
import java.util.Arrays;
import java.util.Iterator;import javax.servlet.http.HttpServletRequest;import org.springframework.web.multipart.MultipartFile;import com.sslt.common.GlobalState;
import com.sslt.common.ResultBean;/*** 文件校验* @author MINI**/
public class FileUploadToolUtil {// 文件最大500Mprivate static long upload_maxsize = 500 * 1024 * 1024;// 文件允许格式private static String[] allowFiles = { ".rar", ".doc", ".docx", ".zip",".pdf", ".txt", ".swf", ".xlsx", ".gif", ".png", ".jpg", ".jpeg",".bmp", ".xls", ".mp4", ".flv", ".ppt", ".avi", ".mpg", ".wmv",".3gp", ".mov", ".asf", ".asx", ".vob", ".wmv9", ".rm", ".rmvb" };public static ResultBean createFile(MultipartFile multipartFile, HttpServletRequest request) {Integer status = GlobalState.RESULTSTATUS;String msg = "";String fileName = multipartFile.getOriginalFilename().toString();// 判断文件不为空if (multipartFile.getSize() != 0 && !multipartFile.isEmpty()) {// 判断文件大小if (multipartFile.getSize() <= upload_maxsize) {// 文件类型判断if (!checkFileType(fileName)) {status = GlobalState.FAILSTATUS;msg = fileName + "文件，系统暂不支持" + fileName.substring(fileName.lastIndexOf("."),fileName.length()) + "的文件格式！";}} else {status = GlobalState.FAILSTATUS;msg = "文件大小超范围";}} else {status = GlobalState.FAILSTATUS;msg = "上传文件不能为空";}return ResultBean.build(status, msg);}/*** 文件类型判断** @param fileName* @return*/public static boolean checkFileType(String fileName) {Iterator<String> type = Arrays.asList(allowFiles).iterator();while (type.hasNext()) {String ext = type.next();if (fileName.toLowerCase().endsWith(ext)) {return true;}}return false;}/*** 获取文件扩展名** @return string*/public static String getFileExt(String fileName) {return fileName.substring(fileName.lastIndexOf("."));}/*** 依据原始文件名生成新文件名* @return*/public static String getName(String fileName) {Iterator<String> type = Arrays.asList(allowFiles).iterator();while (type.hasNext()) {String ext = type.next();if (fileName.contains(ext)) {String newFileName = fileName.substring(0, fileName.lastIndexOf(ext));return newFileName;}}return "";}/*** 文件大小，返回kb.mb** @return*/public static String getSize(File file) {String size = "";long fileLength = file.length();DecimalFormat df = new DecimalFormat("#.00");if (fileLength < 1024) {size = df.format((double) fileLength) + "BT";} else if (fileLength < 1048576) {size = df.format((double) fileLength / 1024) + "KB";} else if (fileLength < 1073741824) {size = df.format((double) fileLength / 1048576) + "MB";} else {size = df.format((double) fileLength / 1073741824) + "GB";}return size;}}

2、转码和截图处理工具类

DisposeVideoUtils.java 处理视频写入本地磁盘/服务器，将非MP4格式的格式文件进行转码写入处理，并且写入前进行视频截图

package com.sslt.utils;import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

4、业务层：Service层

开发统一接口实现方法，方便于代码维护

（1）Service层接口类 ShortVideoService.java

package com.sslt.service;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import org.springframework.web.multipart.MultipartFile;import com.sslt.common.ResultBean;

5、持久层：DAO层（mapper）

ShortVideoMapper.java

package com.sslt.mapper;import com.sslt.entity.ShortVideo;public interface ShortVideoMapper {public int insertSelective(ShortVideo shortVideo);}

ShortVideoMapper.xml 数据处理SQL语句

 <insert id="insertSelective" parameterType="com.sslt.entity.ShortVideo">insert into short_video<trim prefix="(" suffix=")" suffixOverrides=","><if test="id != null">id,</if><if test="title != null">title,</if><if test="picture != null">picture,</if><if test="descript != null">descript,</if><if test="videoName != null">video_name,</if><if test="videoUrl != null">video_url,</if><if test="subclassId != null">subclass_id,</if><if test="clickNum != null">click_num,</if><if test="likeNum != null">like_num,</if><if test="priority != null">priority,</if><if test="status != null">status,</if><if test="size != null">size,</if><if test="remarks != null">remarks,</if><if test="createBy != null">create_by,</if><if test="createDate != null">create_date,</if><if test="updateBy != null">update_by,</if><if test="updateDate != null">update_date,</if></trim><trim prefix="values (" suffix=")" suffixOverrides=","><if test="id != null">#{id,jdbcType=VARCHAR},</if><if test="title != null">#{title,jdbcType=VARCHAR},</if><if test="picture != null">#{picture,jdbcType=VARCHAR},</if><if test="descript != null">#{descript,jdbcType=VARCHAR},</if><if test="videoName != null">#{videoName,jdbcType=VARCHAR},</if><if test="videoUrl != null">#{videoUrl,jdbcType=VARCHAR},</if><if test="subclassId != null">#{subclassId,jdbcType=VARCHAR},</if><if test="clickNum != null">#{clickNum,jdbcType=INTEGER},</if><if test="likeNum != null">#{likeNum,jdbcType=INTEGER},</if><if test="priority != null">#{priority,jdbcType=CHAR},</if><if test="status != null">#{status,jdbcType=CHAR},</if><if test="size != null">#{size,jdbcType=VARCHAR},</if><if test="remarks != null">#{remarks,jdbcType=VARCHAR},</if><if test="createBy != null">#{createBy,jdbcType=VARCHAR},</if><if test="createDate != null">#{createDate,jdbcType=TIMESTAMP},</if><if test="updateBy != null">#{updateBy,jdbcType=VARCHAR},</if><if test="updateDate != null">#{updateDate,jdbcType=TIMESTAMP},</if></trim></insert>

6、表现层：Controller层（Handler层）

ShortVideoController.java 负责具体的业务模块流程的控制

/*** 视频资源管理Controller* @author MINI**/
@Controller
public class ShortVideoController {@Autowiredprivate ShortVideoService shortVideoService;@Autowiredprivate SubclassService subclassService;@Autowiredprivate DictService dictService;/*** 跳转视频添加页面* @param request* @param response* @param model* @param redirectAttributes* @return*/@RequestMapping(value = {"/openShortVideoData"})public String addShortVideo(HttpServletRequest request, HttpServletResponse response, Model model, RedirectAttributes redirectAttributes){String varId = request.getParameter("varId");if (StringUtils.isNotEmpty(varId)) {ShortVideo shortVideo = shortVideoService.selectByPrimaryKey(varId);model.addAttribute("shortVideo", shortVideo);}List<Subclass> subclassList = subclassService.findAllList(new Subclass());model.addAttribute("subclassList", subclassList);model.addAttribute("priorityList", dictService.findDictList(GlobalState.PRIORITY));model.addAttribute("statusList", dictService.findDictList(GlobalState.VIDEOSTATUS));return "shortVideo/openShortVideoData";}/*** 上传视频资源* @param file* @param request* @param response* @param redirectAttributes* @return*/@RequestMapping(value = "/insertShortVideo", method=RequestMethod.POST)public String insertShortVideo(@RequestParam(value="video") MultipartFile file, HttpServletRequest request, HttpServletResponse response, RedirectAttributes redirectAttributes){ShortVideo shortVideo = (ShortVideo) EntityBuilder.getEntity(request, ShortVideo.class);ResultBean result = shortVideoService.insertShortVideo(request, response, file, shortVideo);redirectAttributes.addFlashAttribute("msgState", result.getStatus());redirectAttributes.addFlashAttribute("message", result.getMsg());if (GlobalState.FAILSTATUS.equals(result.getStatus())) {redirectAttributes.addFlashAttribute("shortVideo", shortVideo);return "redirect:/openShortVideoData";}return "redirect:/allShortVideo";}}

7、视图层：View层

由于界面控制样式较多，前端代码就不沾出来，可根据业务代码参考实现功能，页面根据个人开发即可，下面是我的部分页面效果

8、转码工具下载

视频转码工具ffmpeg.exe和mencoder.exe
