springboot 附件上传排除token springboot ftp上传

一、前端代码

1、html  [ 此处省略其他input标签 ]

<form role="form" enctype="multipart/form-data" method="post" action="/sell/seller/product/save">
 <div id="preview" style="height: 110px;margin-top: 5px;margin-bottom: 5px;">
     <img id="imghead" border="0" height="100px" width="100px" src="/sell/image/update.png"   onclick="$('#previewImg').click();">
  </div>
    <#-- 预览图片-->
    <input type="file" name="uploadFile" value="" onchange="previewImage(this)"  style="display: none;" id="previewImg" >
  <button type="submit" class="btn btn-default">提交</button>
</form>

2、javascript

<script type="text/javascript" src="/sell/js/jquery-2.1.0.js"></script>

/图片上传预览    IE是用了滤镜。
function previewImage(file) {
   var MAXWIDTH = 90;
   var MAXHEIGHT = 90;
   var div = document.getElementById('preview');
   div.innerHTML = '<img id=imghead onclick=$("#previewImg").click()>';
   var img = document.getElementById('imghead');
   img.onload = function() {
      var rect = clacImgZoomParam(MAXWIDTH, MAXHEIGHT, img.offsetWidth, img.offsetHeight);
      img.width = rect.width;
      img.height = rect.height;
      //           img.style.marginLeft = rect.left+'px';
      img.style.marginTop = rect.top + 'px';
   }
   var reader = new FileReader();
   reader.onload = function(evt) {
      img.src = evt.target.result;
   }
   reader.readAsDataURL(file.files[0]);
}
//图片上传
function clacImgZoomParam(maxWidth, maxHeight, width, height) {
   var param = {
      top: 0,
      left: 0,
      width: width,
      height: height
   };
   if(width > maxWidth || height > maxHeight) {
      rateWidth = width / maxWidth;
      rateHeight = height / maxHeight;

      if(rateWidth > rateHeight) {
         param.width = maxWidth;
         param.height = Math.round(height / rateWidth);
      } else {
         param.width = Math.round(width / rateHeight);
         param.height = maxHeight;
      }
   }
   param.left = Math.round((maxWidth - param.width) / 2);
   param.top = Math.round((maxHeight - param.height) / 2);
   return param;
}

二、SpringBoot后台

1、Controller

处理表单提交的内容，既可新增，又可修改。当图片文件未更新是，不用上传

@PostMapping("/save")
public ModelAndView save(@Valid ProductForm productForm,  //获取其他input标签内容，自动封装
                         BindingResult bindingResult,  //验证参数是否合法
                         Map<String,Object> map,  //ModelAndview返回绑定内容
                         @RequestParam(value = "uploadFile" , required = false) MultipartFile uploadFile){
    if (bindingResult.hasErrors()){
        map.put("msg",bindingResult.getFieldError().getDefaultMessage());
        map.put("url","/sell/seller/product/list");
        return new ModelAndView("common/error",map);
    }

    ProductInfo productInfo = new ProductInfo();
    try {
        if(!StringUtils.isEmpty(productForm.getProductId())){
            productInfo = productService.findOne(productForm.getProductId());
        }else {  //如果productId为空，表示是新增
            productForm.setProductId(KeyUtil.getUniqueKey());
        }
        //判断是否需要更新图片
        if (uploadFile.isEmpty()){//表示文件没有更新，不用上传
            log.info("[不需要更新图片]");
            //如果productId不为空，表示记录已经存在
        }else {
            log.info("[要更新图片]");
            Map uploadPictureMap = pictureService.uploadPicture(uploadFile);
            productForm.setProductIcon(uploadPictureMap.get("url").toString());
        }
        BeanUtils.copyProperties(productForm,productInfo);
        productService.save(productInfo);
    }catch (SellException e){
        map.put("msg",e.getMessage());
        map.put("url","/sell/seller/product/list");
        return new ModelAndView("common/error",map);
    }

    map.put("url","/sell/seller/product/list");
    return new ModelAndView("common/success", map);
}

2、Service层的uploadPicture方法

上传文件到ftp服务器，相关配置来自配置文件

@Service
public class PictureServiceImpl implements PictureService {

    @Autowired
    private ImageServerConfig imageServerConfig;

    @Override
    public Map uploadPicture(MultipartFile uploadFile) {
        Map resultMap = new HashMap<>();
        try {
            //生成一个新的文件名
            //取原始文件名
            String oldName = uploadFile.getOriginalFilename();
            //生成新文件名
            //UUID.randomUUID();
            String newName = KeyUtil.getUniqueKey();
            newName = newName + oldName.substring(oldName.lastIndexOf("."));
            //图片上传
            String imagePath = new DateTime().toString("/yyyy/MM/dd");
            boolean result = FtpUtil.uploadFile(imageServerConfig.getAddress(), imageServerConfig.getPort(), imageServerConfig.getUsername(), imageServerConfig.getPassword(),
                    imageServerConfig.getBastPath(), imagePath, newName, uploadFile.getInputStream());
            //返回结果
            if(!result) {
                resultMap.put("error", 1);
                resultMap.put("message", "文件上传失败");
                return resultMap;
            }
            resultMap.put("error", 0);
            //上传成功后图片的存储路径
            resultMap.put("url", imageServerConfig.getImageBaseUrl() + imagePath + "/" + newName);
            return resultMap;

        } catch (Exception e) {
            resultMap.put("error", 1);
            resultMap.put("message", "文件上传发生异常");
            return resultMap;
        }
    }
}

3、ImageServerConfig及相关配置

ImageServerConfig类读取配置文件中的ftp服务器配置：

@Data
@Component
@ConfigurationProperties(prefix = "ftp")
public class ImageServerConfig {

    private String address;

    private Integer port;

    private String username;

    private String password;

    private String bastPath;

    private String imageBaseUrl;
}

application.yml配置文件：

ftp:
  address: 192.168.116.137
  port: 21
  username: ftpuser
  password: ftpuser
  bastPath: /home/ftpuser/www/images
  imageBaseUrl: http://192.168.116.137/images

以上就是SpringBoot图片上传的步骤，欢迎指教！！
