基于springboot微信公众号开发(微信自动回复)
人气:0效果图
1.准备工作
申请微信订阅号(个人只能申请订阅号,而且没什么功能,也无法认证),申请完毕,点击 开发=>基本配置,如下图:
服务器配置需要有 域名 80端口,我猜你没有,这里推荐个实用工具,pagekite,下载链接,
这个工具需要 python2.7以上环境,还有邮箱一个,一个邮箱一个月,邮箱这东西大家懂得,
用pagekite申请完域名,就可以用自己的电脑做订阅号服务器了.
2.服务器代码
创建个springboot工程

入口类
@SpringBootApplication
public class WeChatApplication {
public static void main(String[] args) {
