        } else {

        }
    }
}

@Override
    public Locale resolveLocale(HttpServletRequest request) {
//拿请求里面的language属性
        String language = request.getParameter("language");
        //如果没有就使用默认的
        Locale locale = Locale.getDefault();
        //如果请求的连接携带了国际化的参数
        if (!StringUtils.isEmpty(language)) {
