赋值变量给短信模板

78 阅读 0 评论 52 点赞

我是靠谱客的博主微笑白昼，最近开发中收集的这篇文章主要介绍赋值变量给短信模板，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

int month = 6;
int day  = 13;
Map<String,Object> map = new HashMap<String, Object>();
map.put("month",String.valueOf(month));
map.put("day",String.valueOf(day));

String template = "申请于${month}月${day}日已审核通过，款项将于7个工作日返回支付宝账户。请注意查收。";
String str = StringUtils.reString(template, map);

System.out.println(str);

打印结果：申请于6月13日已审核通过，款项将于7个工作日返回支付宝账户。请注意查收。

StringUtils如下：
