	private void writeResponse(String msg, HttpServletResponse response) throws Exception {
		response.setCharacterEncoding("utf-8");
		PrintWriter out = response.getWriter();
		out.println(msg);
		out.flush();
		out.close();
	}

 导入JS：<script src="<%=request.getContextPath()%>/common/js/utils/ajaxfileupload.js" type="text/javascript"></script>

				    <input id="myfiles" name="myfiles" type="file" />
				    <a class="blue-btn-coom-2 tcenter smibat" id="addBtn">确认</a>
