Springboot播放视频
1. Controller层示例
返回数据库数据时，使用了pagehelp当中的PageInfo，为了后期扩展分页功能，正常写法返回值类型应为实体类Video.
package com.dvms.controller;
/*
*文件名: VideoController
*创建者: CJW
*创建时间: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;
//查出记录
@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";
}
// 查出视频地址
@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层
package com.dvms.service;
import com.dvms.entity.Record;
import com.dvms.entity.Video;
import java.util.List;
import java.util.Map;
/*
*文件名: ParamoduleService
*创建者: CJW
*创建时间:2022/1/15 10:54
*描述: TODO
*/
public interface ParamoduleService {
String findvideo(String id);
List<Video> findvideorecord();
}
3. ServiceImpl层
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;
/*
*文件名: ParamoduleServiceImpl
*创建者: CJW
*创建时间:2022/1/15 10:55
*描述: TODO
*/
@Service
public class ParamoduleServiceImpl implements ParamoduleService {
@Autowired
private ParamoduleDao paramoduleDao;
//查出视频文件地址
@Override
public String findvideo(String id){
return paramoduleDao.findvideo(id);
}
//查出视频记录
@Override
public List<Video> findvideorecord(){
return paramoduleDao.findvideorecord();
}
}
4. dao(mapper)层
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;
/*
*文件名: ParamoduleDao
*创建者: CJW
*创建时间:2022/1/15 10:52
*描述: TODO
*/
@Repository
public interface ParamoduleDao {
String findvideo(String id);
List<Video> findvideorecord();
}
4. entity(pojo)层
package com.dvms.entity;
/*
*文件名: Video
*创建者: CJW
*创建时间: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) //链式调用
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">
<!--查询存在视频-->
<select id="findvideo" resultType="String">
select filepath from video where id=#{id}
</select>
<!--查询存在视频记录-->
<select id="findvideorecord" resultType="Video">
select id,filename,filepath from video
</select>
</mapper>
6. video数据库表结构
前端需引入thymeleaf、bootstrap等
1. videorecord.html
<div class="main col-md-9 ml-sm-auto col-lg-10 pt-3 px-4">
<!-- MAIN CONTENT -->
<div class="main-content">
<div class="container-fluid">
<h4 class="page-title">视频管理</h4>
<div class="row">
<div class="col-md-15">

<div class="panel">
<div class="panel-heading">
<div><h4 class="panel-title" >视频记录</h4></div>

<div class="panel-body">

<tr th:class="${rowstate.odd}?'row1':'row2'" th:each="video,rowstate:${videorecord.list}">

<td class="text-center">

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