springboot 中打印 sql 语句

在配置文件中 application.yml 配置如下其一即可

方式一：

logging:
    level:
      com.xxx.com.dao.mapper: DEBUG //包路径为mapper文件包路径

打印出来的形式如下：

-- ::14.245 [http-nio--exec-] DEBUG c.s.a.m.m.U.getUsernameExistSet  - ==>  Preparing: SELECT username FROM user_info WHERE username in ( ? , ? , ? )
-- ::14.245 [http-nio--exec-] DEBUG c.s.a.m.m.U.getUsernameExistSet  - ==> Parameters: nike16(String), nike14(String), nike15(String)
-- ::14.307 [http-nio--exec-] DEBUG c.s.a.m.m.U.getUsernameExistSet  - <==      Total:
