Hibernate 显示真实的 SQL

2022-01-30 00:00:00 sql orm java Hibernate

如果我设置

<property name="show_sql">true</property>

在控制台的hibernate.cfg.xml配置文件中，我可以看到SQL.

in my hibernate.cfg.xml configuration file in the console I can see the SQL.

但它不是真正的 SQL...我可以看到将直接传递给数据库的 SQL 代码吗?

But it's not real SQL... Can I see the SQL code that will be passed directly to database?

例子:

我明白了

select this_.code from true.employee this_ where this_.code=?

我可以看看

select employee.code from employee where employee.code=12

真正的 SQL?

推荐答案

log4j.properties

log4j.logger.org.hibernate=INFO, hb log4j.logger.org.hibernate.SQL=DEBUG log4j.logger.org.hibernate.type=TRACE log4j.logger.org.hibernate.hql.ast.AST=info log4j.logger.org.hibernate.tool.hbm2ddl=warn log4j.logger.org.hibernate.hql=debug log4j.logger.org.hibernate.cache=info log4j.logger.org.hibernate.jdbc=debug log4j.appender.hb=org.apache.log4j.ConsoleAppender log4j.appender.hb.layout=org.apache.log4j.PatternLayout log4j.appender.hb.layout.ConversionPattern=HibernateLog --> %d{HH:mm:ss} %-5p %c - %m%n log4j.appender.hb.Threshold=TRACE

hibernate.cfg.xml

<property name="show_sql">true</property> <property name="format_sql">true</property> <property name="use_sql_comments">true</property>

persistence.xml
一些框架使用persistence.xml:

<property name="hibernate.show_sql" value="true"/> <property name="hibernate.format_sql" value="true"/> <property name="hibernate.use_sql_comments" value="true"/>
