mybatis(mybatis-spring-boot-starter:1.3.5):3.4.6
mybatis-generator-core:1.4.0

when I upgrade mybatis to 3.5.4, I got another error:
java.sql.SQLException: Conversion not supported for type java.time.LocalDateTime

I used to use following versions, everything works fine :
mybatis(mybatis-spring-boot-starter:1.3.5):3.4.6
mybatis-generator-core:1.3.7
mybatis-dynamic-sql:1.1.2

There was a change in MyBatis version 3.5.1 in this area. MyBatis now requires a JDBC driver that implements JDBC 4.2. Make sure you've upgrade your JDBC driver. According to the following thread, it should work with connector-java 8.0.19: https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/mybatis-user/NowScQE4_zc/zV7xkyOlBAAJ

It is related to the following change in MyBatis: mybatis/mybatis-3#1478
