Spring Boot JDBC Template SQL Log

Try

log4j.category.org.springframework.jdbc.core = TRACE

The above statement will print SQL queries with inbound parameters as well.

Incase you need to log only the query use the following

log4j.category.org.springframework.jdbc.core = DEBUG

You can enable in your logback file with the following

<logger name="org.springframework.jdbc.core.JdbcTemplate">
  <level value="debug" />
</logger>

<logger name="org.springframework.jdbc.core.StatementCreatorUtils">
  <level value="debug" />
</logger>

Update : For Springboot 2.x , it would be

logging.level.org.springframework.jdbc.core=TRACE

Thanks zhuguowei!

Adding the following to your properties file also works:

logging.level.org.springframework.jdbc.core = TRACE
