方式一:指定mybatis日志级别 # application.yml mybatis:configuration:log-impl: org.apache.ibatis.logging.stdout.StdOutImpl# 等价于application.properties mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl 方式二、Mybatis-Plus配置(如果用了 Mybatis-Plus ) # 开启mybatis-plus自带SQL打印 mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl 方式三、mybatis-config.xml 配置(一般是在配置文件中指定了读取 mybatis-config 才这样写) <configuration><settings><setting name="logImpl" value="STDOUT_LOGGING"/></settings> </configuration>
