mybatis如何開啓打印sql

1.spring 項目中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD SQL Map Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
 
<configuration>
    <settings>
<setting name="logImpl" value="STDOUT_LOGGING" />
  </settings>
</configuration>

2.springboot

mybatis:
	configuration:
		log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
