RuoYiConfig新增一个路径存储用户头像

本文主要是介绍RuoYiConfig新增一个路径存储用户头像，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

/** 上传头像路径 */
private static String userAvatar;

public static String getUserAvatar() {return userAvatar;
}public  void setUserAvatar(String userAvatar) {RuoYiConfig.userAvatar = userAvatar;
}

/*** 获取头像上传路径*/
public static String getUserAvatarPath()
{return getUserAvatar() + "/avatar";
}

自己重写一个别用它的upload,

/*** 头像上传*/
@Log(title = "用户头像", businessType = BusinessType.UPDATE)
@PostMapping("/avatar")
public AjaxResult avatar(@RequestParam("avatarfile") MultipartFile file) throws Exception
{if (!file.isEmpty()){LoginUser loginUser = getLoginUser();String avatar = FileUploadUtils.uploadUserAvatar(RuoYiConfig.getUserAvatarPath(), file, MimeTypeUtils.IMAGE_EXTENSION);if (userService.updateUserAvatar(loginUser.getUsername(), avatar)){AjaxResult ajax = AjaxResult.success();ajax.put("imgUrl", avatar);// 更新缓存用户头像loginUser.getUser().setAvatar(avatar);tokenService.setLoginUser(loginUser);return ajax;}}return error("上传图片异常，请联系管理员");
}

public static final String uploadUserAvatar(String baseDir, MultipartFile file, String[] allowedExtension)throws FileSizeLimitExceededException, IOException, FileNameLengthLimitExceededException,InvalidExtensionException
{int fileNamelength = Objects.requireNonNull(file.getOriginalFilename()).length();if (fileNamelength > FileUploadUtils.DEFAULT_FILE_NAME_LENGTH){throw new FileNameLengthLimitExceededException(FileUploadUtils.DEFAULT_FILE_NAME_LENGTH);}assertAllowed(file, allowedExtension);//String fileName = extractFilename(file);String fileName = file.getOriginalFilename();String absPath = getAbsoluteFile(baseDir, fileName).getAbsolutePath();file.transferTo(Paths.get(absPath));return getPathFileNameUserAvatar(baseDir, fileName);
}

public static final String getPathFileNameUserAvatar(String uploadDir, String fileName) throws IOException
{int dirLastIndex = RuoYiConfig.getUserAvatar().length() + 1;String currentDir = StringUtils.substring(uploadDir, dirLastIndex);return Constants.RESOURCE_PREFIX + "/" + currentDir + "/" + fileName;
}

标红的改成你的getUserAvatar()
