上传文件，图片、文件都可以

控制器类

@ApiOperation(value = "上传附件")
        @PostMapping("/ms_content/{message_id}")
        @ApiImplicitParams({
                @ApiImplicitParam(name = "message_id",value = "短信id",dataType = "int",paramType = "path",required = true)
        })
        public ResultMessage file(@RequestPart(required = true) MultipartFile file,@PathVariable("message_id")Integer message_id){
            InputStream inSt = null;
            try {
                if (!file.isEmpty()) {
                    String name = file.getName();
                    String OriginName = file.getOriginalFilename();
    
                    SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd/");
                    String path = "E:/"+sdf.format(new Date());;
                    inSt = file.getInputStream();
                    boolean boo = this.msgContentInfoService.file(inSt, path, OriginName, message_id);
                    if (!boo){
                        return ResultMessage.Error("上传失败");
                    }
                    return ResultMessage.Success("上传成功");
                }
            } catch (Exception e){
                e.printStackTrace();
            }finally {
                if (inSt != null){
                    try {
                        inSt.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
    
            }
            return ResultMessage.Success("上传成功");
        }

**注意OriginName 文件名称，尽量使用上传文件获取的名称，设置成自定义名称会出现上传后的文件格式错误，自我觉得应该不知道该文件是什么格式了，我用的OriginName 获取到的名称。**

serverImpl实现类

@Override
        public boolean file(InputStream input, String path, String name,Integer message_id) {
            FileOutputStream fos = null;
            try {
                 File file = new File(path);
                 if (!file.exists()){
                     file.mkdirs();
                 }
                 fos = new FileOutputStream(path+name);
                 byte[] b = new byte[1024];
                 int len = 0;
                 int contlength = 0;
                 while ((len=input.read(b))!=-1){
                     contlength+=len;
                     fos.write(len);
                     fos.flush();
                }
                System.out.println("长度·········"+contlength);
                if (this.baseMapper.updateFilePath(message_id,path+name)<1){
                    return  false;
                }
            } catch (Exception e) {
                e.printStackTrace();
            }finally {
                if (fos!=null){
                    try {
                        fos.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
                if (input!=null){
                    try {
                        input.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            }
    
            return true;
        }
