Why "java.sql.SQLException: Incorrect string value..." is happened with MySQL and JPA

Question

I develop API with following tools.

• Kotlin 1.3.61
• Spring Boot 2.2.4
• Docker
• JPA
• MySQL 8.0

Application and database are build with docker.

I tried insert data with UUID, but "java.sql.SQLException: Incorrect string value..." was happened.

The stacktrace is following.

Hibernate: select todo0_.id as id1_0_0_, todo0_.content as content2_0_0_, todo0_.created_at as created_3_0_0_, todo0_.is_done as is_done4_0_0_, todo0_.updated_at as updated_5_0_0_ from todo todo0_ where todo0_.id=?
Hibernate: insert into todo (content, created_at, is_done, updated_at, id) values (?, ?, ?, ?, ?)

I researched this error, and I could find the article which said this cause was character set.

But My my.conf already set character set to utf8mb4 and database variables were utf8mb4.

my.conf

[mysqld]
character-set-server=utf8mb4
explicit-defaults-for-timestamp=1
general-log=1
general-log-file=/var/log/mysql/mysqld.log

[client]
default-character-set=utf8mb4

result of "show variables like "chara%";"

My application.yml was not written character set expressly, so I added "?character_set_server=utf8mb4" following.

application.yml

After added character set to application.yml, I tried to insert again but result was not changed.

Why "java.sql.SQLException: Incorrect string value..." is happend?

the part of source codes are following.

Answer 1

I had the same problem, i solved added this to yml config:

spring: jpa: hibernate: use-new-id-generator-mappings: false
