使用fckeditor上传多张图片

流程：

1.使用fck上传图片到后台

2.后台上传图片到服务器端

3.服务器端返回上传信息

1.jsp页面

<script type="text/javascript">
$(function(){
    var tObj;
    $("#tabs a").each(function(){
        if($(this).attr("class").indexOf("here") == 0){tObj = $(this)}
        $(this).click(function(){
            var c = $(this).attr("class");
            if(c.indexOf("here") == 0){return;}
            var ref = $(this).attr("ref");
            var ref_t = tObj.attr("ref");
            tObj.attr("class","nor");
            $(this).attr("class","here");
            $(ref_t).hide();
            $(ref).show();
            tObj = $(this);
            if(ref == '#tab_2'){
                var fck = new FCKeditor("productdesc");
                fck.BasePath = "/res/fckeditor/";
                fck.Config["ImageUploadURL"] = "/upload/uploadFck.do";
                fck.Height = 400 ;
                fck.ReplaceTextarea();
            }
        });
    });
});
function uploadPic(){
    var options={
        url:"/upload/uploadPic.do",
        dataType:"json",
        type:"post",
        success:function(data){
            $("#product_url").attr("src",data.url);
            $("#imgUrl").val(data.path);
        }
    };
    $("#jvForm").ajaxSubmit(options);
}
</script>

<tbody id="tab_2" style="display: none">
                <tr>
                    <td >
                        <textarea rows="10" cols="10" id="productdesc" name="description"></textarea>
                    </td>
                </tr>
</tbody>

2.controller层

 //异步上传没有返回值
     @RequestMapping(value="/upload/uploadFck.do")
     public void uploadFck(HttpServletRequest request, HttpServletResponse response){
         MultipartHttpServletRequest ms = (MultipartHttpServletRequest) request;
         Map<String, MultipartFile> filemap = ms.getFileMap();
         Set<Entry<String,MultipartFile>> entrySet = filemap.entrySet();
         for (Entry<String, MultipartFile> entry : entrySet) {
             MultipartFile pic = entry.getValue();
             Client client = new Client();
             ///图片生成策略
             DateFormat df = new SimpleDateFormat("yyyyMMddHHmmssSSS");
             String format = df.format(new Date());
             Random r = new Random();
             for(int i = 0;i<3; i++){
                 format += r.nextInt(10);
             }
             //得到文件扩张名
             String ext = FilenameUtils.getExtension(pic.getOriginalFilename());
             String path = "upload/"+format+"."+ext;
             String url = "http://localhost:8088/image-web/"+path; //服务器路径
             WebResource resource = client.resource(url);
             try {
                resource.put(String.class,pic.getBytes());
            } catch (Exception e) {
                e.printStackTrace();
            }
             UploadResponse ok = UploadResponse.getOK(url);//ok是个对象
            try {
                response.getWriter().print(ok); //使用print可以返回对象
                //write 字符流
                //print 字节流
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

     }
