Java 实战范例之精美网上音乐平台的实现

读万卷书不如行万里路，只学书上的理论是远远不够的，只有在实战中才能获得能力的提升，本篇文章手把手带你用java+vue+Springboot+ssm+mysql+maven+redis实现一个前后端分离的精美网上音乐平台,大家可以在过程中查缺补漏，提升水平

一、项目简述

本系统功能包括：音乐播放用户登录注册用户信息编辑、头像修改歌曲、歌单搜索歌单打分歌单、歌曲评论歌单列表、歌手列表分页显示歌词同步显不音乐收藏、下载、拖动控制、音粉制后台对用户、歌曲、歌手、歌单信息的管理

二、项目运行

环境配置： Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX (Webstorm也行)+ Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持)。

项目技术： Springboot + Maven + Mybatis + Vue + Redis, B/S 模式+ Maven等等

歌手信息操作代码:

 @RestController @Controller public class SingerController { @Autowired private SingerServiceImpl singerService; @Configuration public class MyPicConfig implements WebMvcConfigurer { @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { // registry.addResourceHandler("/img/singerPic/**").addResourceLocations("file:/Users/hongweiyin/Documents/github-workspace/music-website/music-server/img/singerPic/"); } } //    添加歌手 @ResponseBody @RequestMapping(value = "/singer/add", method = RequestMethod.POST) public Object addSinger(HttpServletRequest req){ JSONObject jsonObject = new JSONObject(); String name = req.getParameter("name").trim(); String sex = req.getParameter("sex").trim(); String pic = req.getParameter("pic").trim(); String birth = req.getParameter("birth").trim(); String location = req.getParameter("location").trim(); String introduction = req.getParameter("introduction").trim(); Singer singer = new Singer(); DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd"); Date myBirth = new Date(); try { myBirth = dateFormat.parse(birth); }catch (Exception e){ e.printStackTrace(); } singer.setName(name); singer.setSex(new Byte(sex)); singer.setPic(pic); singer.setBirth(myBirth); singer.setLocation(location); singer.setIntroduction(introduction); boolean res = singerService.addSinger(singer); if (res){ jsonObject.put("code", 1); jsonObject.put("msg", "添加成功"); return jsonObject; }else { jsonObject.put("code", 0); jsonObject.put("msg", "添加失败"); return jsonObject; } } //    返回所有歌手 @RequestMapping(value = "/singer", method = RequestMethod.GET) public Object allSinger(){ return singerService.allSinger(); } //    根据歌手名查找歌手 @RequestMapping(value = "/singer/name/detail", method = RequestMethod.GET) public Object singerOfName(HttpServletRequest req){ String name = req.getParameter("name").trim(); return singerService.singerOfName(name); } //    根据歌手性别查找歌手 @RequestMapping(value = "/singer/sex/detail", method = RequestMethod.GET) public Object singerOfSex(HttpServletRequest req){ String sex = req.getParameter("sex").trim(); return singerService.singerOfSex(Integer.parseInt(sex)); } //    删除歌手 @RequestMapping(value = "/singer/delete", method = RequestMethod.GET) public Object deleteSinger(HttpServletRequest req){ String id = req.getParameter("id"); return singerService.deleteSinger(Integer.parseInt(id)); } //    更新歌手信息 @ResponseBody @RequestMapping(value = "/singer/update", method = RequestMethod.POST) public Object updateSingerMsg(HttpServletRequest req){ JSONObject jsonObject = new JSONObject(); String id = req.getParameter("id").trim(); String name = req.getParameter("name").trim(); String sex = req.getParameter("sex").trim(); String pic = req.getParameter("pic").trim(); String birth = req.getParameter("birth").trim(); String location = req.getParameter("location").trim(); String introduction = req.getParameter("introduction").trim(); Singer singer = new Singer(); DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd"); Date myBirth = new Date(); try { myBirth = dateFormat.parse(birth); }catch (Exception e){ e.printStackTrace(); } singer.setId(Integer.parseInt(id)); singer.setName(name); singer.setSex(new Byte(sex)); singer.setPic(pic); singer.setBirth(myBirth); singer.setLocation(location); singer.setIntroduction(introduction); boolean res = singerService.updateSingerMsg(singer); if (res){ jsonObject.put("code", 1); jsonObject.put("msg", "修改成功"); return jsonObject; }else { jsonObject.put("code", 0); jsonObject.put("msg", "修改失败"); return jsonObject; } } //    更新歌手头像 @ResponseBody @RequestMapping(value = "/singer/avatar/update", method = RequestMethod.POST) public Object updateSingerPic(@RequestParam("file") MultipartFile avatorFile, @RequestParam("id")int id){ JSONObject jsonObject = new JSONObject(); if (avatorFile.isEmpty()) { jsonObject.put("code", 0); jsonObject.put("msg", "文件上传失败！"); return jsonObject; } String fileName = System.currentTimeMillis()+avatorFile.getOriginalFilename(); String filePath = System.getProperty("user.dir") + System.getProperty("file.separator") + "img" + System.getProperty("file.separator") + "singerPic" ; File file1 = new File(filePath); if (!file1.exists()){ file1.mkdir(); } File dest = new File(filePath + System.getProperty("file.separator") + fileName); String storeAvatorPath = "/img/singerPic/"+fileName; try { avatorFile.transferTo(dest); Singer singer = new Singer(); singer.setId(id); singer.setPic(storeAvatorPath); boolean res = singerService.updateSingerPic(singer); if (res){ jsonObject.put("code", 1); jsonObject.put("pic", storeAvatorPath); jsonObject.put("msg", "上传成功"); return jsonObject; }else { jsonObject.put("code", 0); jsonObject.put("msg", "上传失败"); return jsonObject; } }catch (IOException e){ jsonObject.put("code", 0); jsonObject.put("msg", "上传失败" + e.getMessage()); return jsonObject; }finally { return jsonObject; } } }
