如何设置hibernate打印sql语句

Posted 2023-04-01

参考技术A 只要加上下面这个语句就可以了 Log4j.propreties代码 #输出sql语句到日志 log4j.logger.org.hibernate.SQL=debug #将对应的参数占位符？换成传入的参数 log4j.logger.org.hibernate.type=trace本回答被提问者采纳

如何将Hibernate生成的SQL语句打印到日志文件

背景：项目开发需要。

1 操作

只需要在log4j.properties中加入以下两行代码即可

#输出sql语句到日志  
log4j.logger.org.hibernate.SQL=debug  
  
#将对应的参数占位符？换成传入的参数  
log4j.logger.org.hibernate.type=trace

 

实验效果：

可以看到查询的过程和结果都进行了输出。
