疫苗-mysql JSON类型，myBatis不支持

### Cause: com.mysql.cj.jdbc.exceptions.MysqlDataTruncation: Data truncation: Cannot create a JSON value from a string with CHARACTER SET 'binary'.

; ]; Data truncation: Cannot create a JSON value from a string with CHARACTER SET 'binary'.; nested exception is com.mysql.cj.jdbc.exceptions.MysqlDataTruncation: Data truncation: Cannot create a JSON value from a string with CHARACTER SET 'binary'.] with root cause

com.mysql.cj.jdbc.exceptions.MysqlDataTruncation: Data truncation: Cannot create a JSON value from a string with CHARACTER SET 'binary'.

myBatis 自动生成的json类型为OTHER，对象类型为 Object,

发现myBatis现在并不支持JOSN，保存报错

解决办法

将对象换成 String 类型，mapper 文件里换成对应的VARCHAR类型，toJSONString保存
