之前有说道搭建fastdfs作为图片服务器，但是没有说明如何真正在代码里调用，那么今天大致讲一下，如何使用java客户端进行上传

首先你得要有一个客户端，导入到eclipse中即可

git地址如下：

https://github.com/leechenxiang/fastdfs-client-java

js:

$(function () {    $('#fileupload').fileupload({        dataType: 'json',        done: function (e, data) {            console.log(data);              if (data.result.status != "200") {                alert(data.result.msg);            } else {                $.each(data.result.data, function (index, file) {                  $("#lee").html("");                  $("#picUrl").attr("value", file.urlDB);              });             }        },        progressall: function (e, data) {            var progress = parseInt(data.loaded / data.total * 100, 10);            $('#progress .bar').css(                'width',                progress + '%'            );           },        dropZone: $('#dropzone')    });});

html:

        
     
      Drop files here
     
        
     
        
      
    
     
        
     

controller:

@RequestMapping(value="/upload", method = RequestMethod.POST)    @ResponseBody    public LeeJSONResult upload(MultipartHttpServletRequest request, HttpServletResponse response) throws Exception {        List
     
       picList = new ArrayList
      
       ();                Iterator
       
         itr = request.getFileNames();        MultipartFile mpf = null;        while (itr.hasNext()) {            mpf = request.getFile(itr.next());            PictureResult pic = pictureService.uploadPic(mpf);            picList.add(pic);        }                return LeeJSONResult.ok(picList);    }
       
      
     

service:

@Value("${IMAGE_SERVER_BASE_URL}")    private String IMAGE_SERVER_BASE_URL;        @Value("${SERVER_PATH}")    private String SERVER_PATH;        @Override    public PictureResult uploadPic(MultipartFile picFile) {        PictureResult result = new PictureResult();        // 判断图片是否为空        if (picFile.isEmpty()) {            result.setError(YesOrNo.YES.value);            result.setMessage("图片为空");            return result;        }        // 上传到图片服务器        try {            // 取图片扩展名            String originalFilename = picFile.getOriginalFilename();            // 取扩展名不要“.”            String extName = originalFilename.substring(originalFilename.lastIndexOf(".") + 1);            FastDFSClient client = new FastDFSClient("classpath:resource/client.conf");            String url = client.uploadFile(picFile.getBytes(), extName);            // 把url响应给客户端            result.setError(YesOrNo.NO.value);            result.setUrlDB(url);            result.setUrl(IMAGE_SERVER_BASE_URL + url);        } catch (Exception e) {            e.printStackTrace();            result.setError(YesOrNo.YES.value);            result.setMessage("图片上传失败");        }        return result;    }

最后配置：
