Response乱码的解决方法
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//告诉servlet用UTF-8转码 request.setCharacterEncoding("UTF-8"); response.setCharacterEncoding("UTF-8");
//浏览器用utf8来解析返回的数据 response.setContentType("text/html; charset=UTF-8"); }
