数据库:sqlserver
项目:springboot
开发工具:idea
第一种:IDEA插件
修改配置application.properties
mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl
settings->Plugins->Marketplace 搜索 Mybatis Log
在Debug控制台右键
效果
第二种 拦截器

mysql
以上方案mysql也可以,另外Mysql还可以如下修改打印完整sql
jdbc.url=jdbc:mysql://127.0.0.1/test?useUnicode=true&characterEncoding=UTF-8&useLegacyDatetimeCode=false&serverTimezone=Asia/Shanghai&logger=com.mysql.jdbc.log.Slf4JLogger&profileSQL=true
