部分代码：

宠物操作

 //发布宠物出售或购买请求@PostMapping("/addPet")public String addPet(@RequestParam(name = "files",required = false) MultipartFile[] files,Pet pet) throws IOException {Date date = new Date();pet.setDate(date);petService.addPet(pet);Photo photo = new Photo();photo.setPid(pet.getPid());if (files != null){if (files.length > 0){for (int i=0;i< files.length;i++){//获取当前项目路径//前面拼接uiid是为了防止名字重复，获取文件的后缀名，不使用原文件名是防止文件名格式导致无法显示String filename = createUUID.getUUID() + files[i].getOriginalFilename().substring(files[i].getOriginalFilename().lastIndexOf("."));//创建文件对象，设置文件保存路径File dest = new File(uploadDir +"\\petimg\\"+ filename);//将文件对象转化为文件files[i].transferTo(dest);photo.setUrl("petimg/" + filename);photoService.addPhoto(photo);}}else {photo.setUrl("defaultpetimg/nodata.jpg");photoService.addPhoto(photo);}}return "发布成功";}//删除宠物@GetMapping("/deletePet")public String deletePet(@RequestParam(name = "uid",required = false) Long uid, @RequestParam(name = "pid",required = false) Long pid){Map map = new HashMap();if(uid != null){map.put("uid",uid);}else{map.put("pid",pid);map.put("postatu",0);}List<Petorder> petorder = petorderService.querypetorder(map);map.remove("postatu");if(petorder.size() == 0){petService.deletePet(map);photoService.deletePhoto(map);return "删除成功";}else {return "该宠物已被购买，无法删除";}}//更新宠物信息@PostMapping("/updatePet")public String updatePet(@RequestParam(name = "files",required = false) MultipartFile[] files,@RequestParam(name = "ppid",required = false) Long[] ppid, Pet pet) throws IOException {Date date = new Date();pet.setDate(date);Photo photo = new Photo();photo.setPid(pet.getPid());//删除图片if(ppid != null) {if(ppid.length > 0) {Map photomap = new HashMap();for(int i=0; i < ppid.length; i++) {photomap.put("ppid",ppid[i]);photoService.deletePhoto(photomap);photomap.remove("ppid");}}}//增加图片if(files != null) {if(files.length > 0) {for (int i=0;i< files.length;i++){//获取当前项目路径//获取文件名字,前面拼接uiid是为了防止名字重复String filename = createUUID.getUUID() + files[i].getOriginalFilename();//创建文件对象，设置文件保存路径File dest = new File(uploadDir +"\\petimg\\" + filename);//将文件对象转化为文件files[i].transferTo(dest);photo.setUrl("petimg/" + filename);photoService.addPhoto(photo);}} else {System.out.println("没有新加图片");}}//宠物为求购时，若没有图片，增加无数据图片if(pet.getPk() == 3) {List<Photo> photos = photoService.queryPhotobypid(pet.getPid());if(photos.size() == 0) {photo.setUrl("defaultpetimg/nodata.jpg");photoService.addPhoto(photo);}}petService.updatePet(pet);return "修改完成";}

用户操作

//修改用户信息@PostMapping("/updateuser")public Map updateuser(@RequestParam(name = "file",required = false) MultipartFile file, User user) throws IOException {Map map = new HashMap();User uuser = null;if(user.getTelphone() != null){map.put("telphone",user.getTelphone());uuser = userService.queryUser(map);map.remove("telphone");if(uuser != null && uuser.getUid() != user.getUid()){map.put("flag",0);map.put("msg","该手机号已被注册");return map;}}if(user.getUsername() != null){map.put("username",user.getUsername());uuser = userService.queryUser(map);map.remove("username");}if(uuser == null || uuser.getUid() == user.getUid()){if(file != null) {if(!file.isEmpty()) {//获取当前项目路径//获取文件名字,前面拼接uiid是为了防止名字重复String filename = createUUID.getUUID() + file.getOriginalFilename();//创建文件对象，设置文件保存路径File dest = new File(uploadDir +"\\avatar\\" + filename);//将文件对象转化为文件file.transferTo(dest);//存入头像地址user.setAvatar("avatar/" + filename);//查找旧的用户信息map.put("uid",user.getUid());uuser = userService.queryUser(map);map.remove("uid");String oldavatar = uuser.getAvatar();int index = oldavatar.indexOf("defaultavatar/");//判断旧头像是否为默认头像，不是则删除旧头像if(index == -1) {//得到旧头像的地址String oldpath = uploadDir +"\\avatar\\" + oldavatar.replace("/", "\\");File olddest = new File(oldpath);//删除旧头像olddest.delete();}}}userService.updateUser(user);map.put("avatar",user.getAvatar());map.put("flag",1);map.put("msg","修改成功");}else {map.put("flag",0);map.put("msg","用户名已存在");}return map;}

以上就是部分功能展示，从整体上来看，本系统功能是十分完整的，界面设计简洁大方，交互友好，数据库设计也很合理，规模适中，代码工整，清晰，适合学习使用。
