Incorrect string value: '\xF0\x9F\x91\x80' for column数据库中添加表情报错

错误信息：

Incorrect string value: '\xF0\x9F\x91\x80' for column

解决方法：

1. 修改数据库中相关字段的字符集为utf8mb4;
2. 或者修改application.yml

spring:
 datasource:
   url: jdbc:mysql://XXX:3306/XXX?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&autoReconnect=true
   username: root
   password: root #
   tomcat:
     init-s-q-l: SET NAMES utf8mb4     //加上这一块
