Springboot main video
1. Contoh lapisan Pengawal
Apabila mengembalikan data pangkalan data, PageInfo dalam pagehelp digunakan Untuk mengembangkan fungsi paging kemudian, jenis nilai pulangan penulisan biasa haruslah Video kelas Entiti.
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. Lapisan Perkhidmatan
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(); }
Lapisan ServiceImpl
rreee4. lapisan dao(mapper)
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. lapisan entiti(pojo)
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(); }
5. daoMapper.xml
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; }
6 struktur jadual pangkalan data video
Bahagian hadapan perlu memperkenalkan thymeleaf, bootstrap, dll.
1. videorecord.html
<?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>
