這篇文章主要介紹了springboot實現(xiàn)執(zhí)行sql語句打印到控制臺的操作，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

springboot 執(zhí)行sql語句打印到控制臺

1.簡介

每當(dāng)寫完持久化語句時肯定免不了要查漏補缺一波。這里就可以將執(zhí)行的sql打印到控制臺來檢查sql語句哪里出了問題。

2.配置

配置非常簡單，只需要在配置文件中設(shè)置下mapper日志級別就可以了

3.代碼

application-test.properties
#logging.level.mapper的路徑=異常級別
logging.level.com.shuhe360.auth.auth_main_car_api.mapper.CarConsumeRecordMapper=DEBUG

4.jpa

如果操作數(shù)據(jù)庫用的jpa也可以來手動開啟打印語句到控制臺的

5.jpa開啟

# JPA 相關(guān)配置
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
#這里開啟sql打印
spring.jpa.show-sql=false
#程序啟動時刪除并創(chuàng)建實體類對應(yīng)的那個表（危險）
spring.jpa.hibernate.ddl-auto=none

springboot 打印sql 語句

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 //包路徑為mapper文件包路徑

打印出來的形式如下：
