Hi @pearina This information here is inadequate. I suggest you give more stack log and SQL.

[tristaZero]

Plush, please rename this title in English. Thx

I find this question too.

env: mysql-connector-java: 8.0.20 mybatis-plus-boot-starter: 3.3.2 sharding-jdbc-spring-boot-starter: 4.1.1

when your entity is LocalDateTime ,so the MyBatis TypeHandler is LocalDateTimeTypeHandler#getNullableResult,

but this is a unsupport operation in ShardingJdbc AbstractUnsupportedOperationResultSet#getObject(columnIndex,type) throws SQLFeatureNotSupportedException

to resolve this question must override method in ShardingResultSet but the parent method is final tag

Is this under repair ？

[terrymanu]

For English only, other languages will not accept.

[EricLye]

what is the reason that closing this issue?

How do I fix it
