控制器

        OutputStream out = null;
        PrintWriter printWriter = null;
        response.setCharacterEncoding("utf-8");
        response.setContentType("text/html;charset=utf-8");

        try {
            String callback = request.getParameter("CKEditorFuncNum");

            UploadFile uploadedFile = awsS3Service.upload(upload);

            printWriter = response.getWriter();
            printWriter.println("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction("

            printWriter.flush();            
        }catch(Exception e){
            e.printStackTrace();
        } finally {
            try {
                if (out != null) {
                    out.close();
                }
                if (printWriter != null) {
                    printWriter.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

我使用的是java，spring框架。我不知道怎么把这个服务改成我的。

UploadFile uploadedFile = awsS3Service.upload(uploadfile);

谢谢您！
