SpringBoot + thymeleaf 實現讀取視訊列表並播放視訊功能

2022-04-16 19:00:11

通過讀取資料庫video表獲取當前視訊的視訊名、視訊地址，展示至前端頁面videorecord.html，通過點選播放按鈕獲取資料id進而得到所選視訊地址，跳轉播放視訊顯示頁videoshow.html，播放所選視訊。當然本案例只是為了展示主要的一些功能，其他比如跳轉、頁面佈局美化等可以自行進行更改。

效果

Springboot播放視訊

實現過程

後端程式範例

1. Controller層範例

返回資料庫資料時，使用了pagehelp當中的PageInfo，為了後期擴充套件分頁功能，正常寫法返回值型別應為實體類Video.

package com.dvms.controller;
/*
 *檔名: VideoController
 *建立者: CJW
 *建立時間:2022/4/14 16:40
 *描述: TODO
 */
import com.dvms.entity.Video;
import com.dvms.service.ParamoduleService;
import com.github.pagehelper.PageInfo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class VideoController {
    @Autowired
    private ParamoduleService paramoduleService;
    //查出記錄
    @RequestMapping("/angle/findvideoRecord")
    public String findvideorecords(Model model){
        System.out.println(paramoduleService.findvideorecord());
        PageInfo<Video> videoRecord = new PageInfo<>(paramoduleService.findvideorecord());
        model.addAttribute("videorecord", videoRecord);
        return "angle/videorecord";
    }
    // 查出視訊地址
    @RequestMapping("/angle/findvideo")
    public String findvideo(String id, String filenamev, Model model){
        System.out.println(id);
        String videopath = paramoduleService.findvideo(id);
        System.out.println(videopath);
        model.addAttribute("videourl",videopath);
        model.addAttribute("videoname",filenamev);
        
        return "angle/videoshow";
}

2. Service層

package com.dvms.service;

import com.dvms.entity.Record;
import com.dvms.entity.Video;

import java.util.List;
import java.util.Map;

/*
 *檔名: ParamoduleService
 *建立者: CJW
 *建立時間:2022/1/15 10:54
 *描述: TODO
 */
public interface ParamoduleService {

    String findvideo(String id);

    List<Video> findvideorecord();

}

3. ServiceImpl層

package com.dvms.service.Impl;

import com.dvms.dao.ParamoduleDao;
import com.dvms.entity.Record;
import com.dvms.entity.Video;
import com.dvms.service.ParamoduleService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
import java.util.Map;

/*
 *檔名: ParamoduleServiceImpl
 *建立者: CJW
 *建立時間:2022/1/15 10:55
 *描述: TODO
 */
@Service
public class ParamoduleServiceImpl implements ParamoduleService {

    @Autowired
    private ParamoduleDao paramoduleDao;

    //查出視訊檔地址
    @Override
    public String findvideo(String id){
        return paramoduleDao.findvideo(id);
    }
    //查出視訊記錄
    @Override
    public List<Video> findvideorecord(){
        return paramoduleDao.findvideorecord();
    }
}

4. dao(mapper)層

package com.dvms.dao;

import com.dvms.entity.Record;
import com.dvms.entity.Video;
import org.springframework.stereotype.Repository;

import java.util.List;
import java.util.Map;

/*
 *檔名: ParamoduleDao
 *建立者: CJW
 *建立時間:2022/1/15 10:52
 *描述: TODO
 */

@Repository
public interface ParamoduleDao {

     String findvideo(String id);

     List<Video> findvideorecord();
}

4. entity(pojo)層

package com.dvms.entity;

/*
 *檔名: Video
 *建立者: CJW
 *建立時間:2022/4/14 16:17
 *描述: TODO
 */

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
import lombok.experimental.Accessors;

@Data
@ToString
@AllArgsConstructor
@NoArgsConstructor
@Accessors(chain = true) //鏈式呼叫

public class Video {

    private String id;
    private String filename;
    private String filepath;

}

5. daoMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.dvms.dao.ParamoduleDao">

    <!--查詢存在視訊-->
    <select id="findvideo" resultType="String">
        select filepath from video where id=#{id}
    </select>

    <!--查詢存在視訊記錄-->
    <select id="findvideorecord" resultType="Video">
        select id,filename,filepath from video
    </select>

</mapper>

6. video資料庫表結構

前端程式範例

前端需引入thymeleaf、bootstrap等

1. videorecord.html

											</td>
										</tr>
									</table>
									<div class="modal-footer no-margin-top">

                                            </td>

                                            </td>
