    /**     * 异步请求响应回写     *      * @param json     * @throws ECApplicationException     */    private void writeAjax(String json) throws ECApplicationException {        String methodName = "writeAjax";        Writer writer = null;        logger.logp(Level.SEVERE, CLASSNAME, methodName, json);        try {            // 获取响应对象，此处可以根据不同的框架结构，进行调整            HttpServletResponse response = (HttpServletResponse) ((ViewCommandContext) this.context)                    .getResponse();            response.setContentType("text/html;charset=UTF-8");            response.setHeader("Cache-Control", "no-cache");            writer = response.getWriter();            writer.write(json);            writer.flush();        } catch (Exception e) {            logger.logp(Level.SEVERE, CLASSNAME, methodName, e.toString(), e);        } finally {            if (writer != null) {                try {                    writer.close();                } catch (IOException e) {                    logger.logp(Level.SEVERE, CLASSNAME, methodName, e1.toString(), e);                }            }        }    }

比如微信支付成功后回写，让微信那边不用再回调了

//告诉微信订单成功不用回调了
res.getWriter().write(WxPayCore.generatePaySuccessReplyXML());
