springboot实现执行sql语句打印到控制台

springboot 执行sql语句打印到控制台

1.简介

每当写完持久化语句时肯定免不了要查漏补缺一波。这里就可以将执行的sql打印到控制台来检查sql语句哪里出了问题。

2.配置

配置非常简单，只需要在配置文件中设置下mapper日志级别就可以了

3.代码

application-test.properties
#logging.level.mapper的路径=异常级别
logging.level.com.shuhe360.auth.auth_main_car_api.mapper.carconsumerecordmapper=debug

4.jpa

如果操作数据库用的jpa也可以来手动开启打印语句到控制台的

5.jpa开启

# jpa 相关配置
spring.jpa.database-platform=org.hibernate.dialect.mysql5innodbdialect
#这里开启sql打印
spring.jpa.show-sql=false
#程序启动时删除并创建实体类对应的那个表（危险）
spring.jpa.hibernate.ddl-auto=none

springboot 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：

方式二：

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

打印出来的形式如下
