实现beetl的function，然后使用spring配置注入该bean即可

public class I18nUtil implements Function{    @Override    public Object call(Object[] obj, Context context) {        if(obj.length < 1) {            try {                throw new BeetlException("调用Beetl方法获取国际化信息时 参数列表传递错误");            } catch (BeetlException e) {                e.printStackTrace();                return "调用Beetl方法获取国际化信息时 参数列表传递错误";            }        }        HttpServletRequest request = (HttpServletRequest) context.getGlobal("request");        RequestContext requestContext = new RequestContext(request);        String message = "";        try {            message = requestContext.getMessage((String)obj[0]);            if("".equals(message) && obj.length > 1){                message = (String)obj[(int)(1+Math.random()*(obj.length-1))];            }        } catch (Exception e) {            e.printStackTrace();            if(obj.length > 1)                message = (String)obj[(int)(1+Math.random()*(obj.length-1))];        }        return message;    }}
