import org.springframework.web.multipart.MultipartFile;import java.io.File; import java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; import java.util.UUID;Controller RequestMapping(/video) public class VideoController {Autowiredprivate VideoService videoService;private final Path rootLocation Paths.get(uploads);PostMapping(/add)public String addVideo(ModelAttribute Video video, RequestParam(file) MultipartFile file) {try {// 保存文件到指定路径String uniqueFileName UUID.randomUUID().toString() _ file.getOriginalFilename();File dest new File(rootLocation.toString(), uniqueFileName);Files.copy(file.getInputStream(), dest.toPath());// 设置文件路径video.setFile_path(uniqueFileName);videoService.addVideo(video);} catch (IOException e) {e.printStackTrace();}return redirect:/video/list;}// 其他方法... }5. 分页查询 在VideoService中添加分页查询的功能。 VideoService.java package com.video.service;import com.video.entity.Video; import com.video.mapper.VideoMapper; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;import java.util.List;Service public class VideoService {Autowiredprivate VideoMapper videoMapper;public ListVideo getAllVideos() {return videoMapper.findAll();}public ListVideo getVideosByPage(int page, int size) {int offset (page - 1) * size;return videoMapper.findVideosByPage(offset, size);}// 其他方法... }VideoMapper.java package com.video.mapper;import com.video.entity.Video; import org.apache.ibatis.annotations.*;import java.util.List;Mapper public interface VideoMapper {Select(SELECT * FROM video)ListVideo findAll();Select(SELECT * FROM video LIMIT #{offset}, #{size})ListVideo findVideosByPage(Param(offset) int offset, Param(size) int size);// 其他方法... }6. 视频列表页的分页功能 在videoList.html中添加分页功能。 videoList.html !DOCTYPE html html xmlns:thhttp://www.thymeleaf.org headtitleVideo List/title /head body h1Video List/h1 table border1trthID/ththTitle/ththDescription/ththFile Path/ththCategory/ththUpload User/ththUpload Time/ththActions/th/trtr th:eachvideo : \){videos}td th:text\({video.id}/tdtd th:text\){video.title}/tdtd th:text\({video.description}/tdtd th:text\){video.file_path}/tdtd th:text\({video.category_id}/tdtd th:text\){video.upload_user_id}/tdtd th:text\({video.upload_time}/tdtda th:href{/video/view/{id}(id\){video.id})}View/aa th:href{/video/edit/{id}(id\({video.id})}Edit/aa th:href{/video/delete/{id}(id\){video.id})}Delete/a/td/tr /tablediva th:if\({currentPage 1} th:href{/video/list(page\){currentPage - 1})}Previous/aa th:if\({currentPage totalPages} th:href{/video/list(page\){currentPage 1})}Next/a /diva href/video/addAdd New Video/a /body /html7. 视频列表控制器的分页支持 在VideoController中添加分页支持。 VideoController.java package com.video.controller;import com.video.entity.Video;
