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("<a href='" + file.url + "' target='_blank'><img src='" + file.url + "' width='80' hight='80'></img></a>");

                  $("#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:

<input id="fileupload" type="file" name="files[]" data-url="/file/upload.action" multiple>

    <div id="dropzone" class="fade well">Drop files here</div>

    <div id="progress" class="progress">

        <div class="bar" style="width: 0%;"></div>

    </div>

    <div id="lee"></div>

controller:

@RequestMapping(value="/upload", method = RequestMethod.POST)

    @ResponseBody

    public LeeJSONResult upload(MultipartHttpServletRequest request, HttpServletResponse response) throws Exception {

        List<PictureResult> picList = new ArrayList<PictureResult>();

        Iterator<String> 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;

    }
