com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data too long for column 'column_name'

[YohLee]

spring.datasource.url=jdbc:mysql://localhost:3306/conweb?sessionVariables=sql_mode='NO_ENGINE_SUBSTITUTION'&jdbcCompliantTruncation=false

---添加jdbcCompliantTruncation=false后不报错，但是插入数据库中内容不完整，需要 alter table tb_task modify column TASK_PARAM MediumText;
