最后发现原因：- redis连接失败，原因是yml配置文件 redis的配置缩进多了一个
报错二

错误原因： 配置名称写错了，跟yml的属性名不一致
@Value("${weixin.config.appid}") //这里被我写成app-id
private String appId;
@Value("${weixin.config.appsecret}") //
private String appSecret;
-
首先修正Retrofit2Config中的微信API域名
-
确保WeixinLoginServiceImpl中的@Value注解key与application-dev.yml配置一致
-
最后 刷新maven
