# springboot实现简单的图片上传 #

## 1. 创建配置类 ##

/**
     * @author flame
     * @version 1.0.0
     * @date 2020/12/13 13:35
     */
    
    @Data
    @ConfigurationProperties("portal.file")
    public class FileConfig {
    
        private List<String> imgList;
        private String imgServerAddress;//图片访问地址
        private String attachServerAddress;//附件访问地址
        private String imageContent;//图片目录
        private String attachContent;//附件目录
    }

## 2. 配置文件中的自定义属性 ##

portal:
      file:
        imgList:
          - .jpg
          - .png
        imgServerAddress: http://image.flame.com/images/ #开发环境
        attachServerAddress: http://image.flame.com/attachments/ #开发环境
        imageContent: D:/document/multi_blog/images #开发环境
        attachContent: D:/document/multi_blog/attachments #开发环境

## 3.创建Controller ##

/**
      * 图片上传
      *
      * @param file 图片
      * @return 视图对象
      */
     @PostMapping("/uploadImg")
     public Result uploadImg(@RequestBody MultipartFile file) {
         String originalFilename = file.getOriginalFilename();
         if (StringUtils.isBlank(originalFilename)) {
             return new Result(StatusCode.FILE_IS_NULL);
         }
         String extensionName = originalFilename.substring(originalFilename.lastIndexOf("."));
         if (!fileConfig.getImgList().contains(extensionName)) {
             return new Result(StatusCode.IMAGES_SORT_ERROR);
         }
         String newFileName = new Date().getTime() + extensionName;
         try {
             file.transferTo(new File(fileConfig.getImageContent(), newFileName));
         } catch (IOException e) {
             return new Result(StatusCode.FILE_UPLOAD_FAIL);
         }
         //返回url
         return new Result(StatusCode.OK, fileConfig.getImgServerAddress() + newFileName);
     }
