原创文章，转载请注明原文章地址，谢谢！

问题：在做第三方用户登录，对接微信用户登录时，服务器报了如下错误，SQLException:Incorrect string value:'\xF0\X9F\X91\X8C' for column 'real_name' 。

发现是微信用户名保存错误，该微信用户名包含了特殊图标，报错了

解决方案：

1）在数据库中把对应的字段编码修改为utf8-> utf8mb4

2）修改application.yml配置文件,在spring.datasource.druid中添加如下配置

connectionInitSqls: "set names utf8mb4"

server:
  port: 8000
