微信被动回复用户消息-文本消息-填坑

一个大坑

private void replyTextMessage(Scan scan, HttpServletResponse response) {
        String reply = getReplyByInput(scan.getContent());
        StringBuffer str = new StringBuffer();
        str.append("<xml>");
        str.append("<ToUserName><![CDATA[" + scan.getFromUserName() + "]]></ToUserName>");
        str.append("<FromUserName><![CDATA[" + scan.getToUserName() + "]]></FromUserName>");
        str.append("<CreateTime>" + Calendar.getInstance().getTimeInMillis() / 1000 + "</CreateTime>");
        str.append("<MsgType><![CDATA[text]]></MsgType>");
        str.append("<Content><![CDATA[" + reply + "]]></Content>");
        str.append("</xml>");
        System.out.println(str.toString());
        try {
            //response.getWriter().write(str.toString());
            // 响应消息  
            PrintWriter out = response.getWriter();  
            out.print(str.toString());  
            out.flush();  
            out.close(); // 这里是个大坑
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
