mybatis

1 返回主键:

<selectKey resultType="java.lang.Long" order="AFTER" keyProperty="id">
SELECT LAST_INSERT_ID() AS id
</selectKey>

2 mybatis日志

log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG

ps:最近把mybatis更新到3.2之后不打印日志了,解决办法  log4j.logger.com.xx.xx.mapper=debug
