mysql 保存emoji时报，数据库报错：Caused by: java.sql.SQLException: Incorrect string value: '\xF0\x9F\x98\x82\xF0\x9F...' for column 'review' at row 1

错误原因:我们可以看到错误提示中的字符0xF0 0x9F 0x98 0x84 ,这对应UTF-8编码格式中的4字节编码(UTF-8编码规范).正常的汉字一般不会超过3个字节,为什么为出现4个字节呢?实际上是它对应的是智能手机输入法中的表情.那为什么会报错呢?因为mysql中的utf-8并不是真正意义上的utf-8,它只能存储1~3个字节长度的utf-8编码,如果想存储4个字节的必须用utf8mb4类型.不而要使用utf8mb4类型,首先要保证Mysql版本要不低于 MySQL 5.5.3. 常用
