1. 视频详情页
创建一个视频详情页面显示视频的详细信息和评论。
videoView.html
!DOCTYPE html
html xmlns:thhttp://www.thymeleaf.org
headtitleVideo Details/title
/head
body
h1Video Details/h1
divh2 th:text${video.title}/h2p th:text${video.description}/pvideo width320 height240 controlssource th:src{${video.file_path}} typevideo/mp4Your browser does not support the video tag./videopCategory: span th:text${video.category.name}/span/ppUploaded by: span th:text${video.uploadUser.username}/span/ppUpload Time: span th:text${video.upload_time}/span/p

/ulform th:action{/video/comment/{id}(id${video.id})} methodpostlabelComment:/labeltextarea namecontent/textareabr/button typesubmitSubmit Comment/button
/form
/body
/html2. 视频评论功能
在VideoController中添加处理评论的逻辑。
VideoController.java
package com.video.controller;import com.video.entity.Comment;
import com.video.entity.Video;
import com.video.service.CommentService;
import com.video.service.VideoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;import java.util.List;Controller
RequestMapping(/video)
public class VideoController {Autowiredprivate VideoService videoService;Autowiredprivate CommentService commentService;GetMapping(/list)public String listVideos(Model model) {ListVideo videos videoService.getAllVideos();model.addAttribute(videos, videos);return videoList;}GetMapping(/view/{id})public String viewVideo(PathVariable(id) int id, Model model) {Video video videoService.getVideoById(id);video.setComments(commentService.getCommentsByVideoId(id));model.addAttribute(video, video);return videoView;}PostMapping(/comment/{id})public String addComment(PathVariable(id) int id, RequestParam(content) String content, Model model) {// 假设已经通过 session 获取到当前用户User currentUser (User) model.getAttribute(currentUser);Comment comment new Comment();comment.setContent(content);comment.setUser(currentUser);comment.setVideo(videoService.getVideoById(id));commentService.addComment(comment);return redirect:/video/view/ id;}// 其他方法...
}3. 用户注册页
创建一个用户注册页面。
register.html
!DOCTYPE html
html xmlns:thhttp://www.thymeleaf.org
headtitleRegister Page/title
/head
body
h1Register/h1
form th:action{/user/register} methodpostlabelUsername:/labelinput typetext nameusername/br/labelPassword:/labelinput typepassword namepassword/br/labelEmail:/labelinput typeemail nameemail/br/labelPhone:/labelinput typetext namephone/br/button typesubmitRegister/button
/form
/body
/html4. 文件上传功能
在VideoController中添加文件上传的逻辑。
VideoController.java
package com.video.controller;import com.video.entity.Video;
import com.video.service.VideoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;
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

/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;
import com.video.service.VideoService;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;import java.util.List;Controller
RequestMapping(/video)
public class VideoController {Autowiredprivate VideoService videoService;GetMapping(/list)public String listVideos(RequestParam(defaultValue 1) int page, Model model) {int pageSize 10; // 每页显示的记录数ListVideo videos videoService.getVideosByPage(page, pageSize);int totalVideos videoService.getAllVideos().size();int totalPages (int) Math.ceil((double) totalVideos / pageSize);model.addAttribute(videos, videos);model.addAttribute(currentPage, page);model.addAttribute(totalPages, totalPages);return videoList;}// 其他方法...
}以上是一些扩展功能的示例。如果有其他具体需求或问题请提供详细信息以便进一步帮助。
