解决方案:

1.url:&serverTimeznotallow=GMT加上这句话

2.加入这两行

细粒度配置可参考如下的URL 配置

db mysql

spring.datasource.platform=mysql db.num=1

db.url.0=jdbc:mysql://localhost:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&serverTimezone=Asia/Shanghai

db.user=root db.password=1234
