java服务器端判断页面请求是否为ajax请求

话不多说，直接上代码

/**     * 检查是否Ajax请求     * @param request     * @return     */    private boolean isAjaxRequest(ServletRequest request) {    HttpServletRequest httpServletRequest = (HttpServletRequest) request;return "XMLHttpRequest".equalsIgnoreCase(httpServletRequest.getHeader("X-Requested-With"));    }
