我有一个使用Hibernate作为提供程序的Spring Data JPA仓库。我想记录SQL语句,但我无法实现。我尝试了各种解决方案:
- 在我的HibernateJpaVendorAdapter中将showSql设置为true
- 在我的log4j.properties文件中添加log4j.logger.org.hibernate.SQL=DEBUG(值得一提的是,log4j.logger.org.hibernate=INFO确实添加了一些日志信息,但log4j.logger.org.hibernate.SQL=DEBUG没有)
这里是我的类和配置文件:

为什么之前的解决方案都没有起作用?Spring Data JPA和Hibernate SQL日志配置之间是否存在某种不兼容性?
编辑: 我尝试了评论中提出的两个解决方案,但都没有生效。我还尝试更改我使用的数据库(从H2到HSQL)或指定Hibernate方言,但都没有生效。事实上,在使用Spring时,对于某些数据库,Hibernate方言会自动找到。
编辑2: 我尝试将rootLogger的日志级别更改为TRACE。我还尝试为appender明确指定阈值。最后,我尝试添加具有showSql = true的JpaProperties,但它们都没有起作用。我认为有些非常明显的事情可以做,但我错过了完整的情况:-/
编辑3: 直接调用记录器,如下面的测试所示,确实有效。我开始怀疑是否存在打字错误或其他问题,防止Hibernate使用记录器。
@Test
public void delete() {
LoggerFactory.getLogger("org.hibernate.SQL").debug("delete()");
repository.delete(MICROSOFT);
assertNull(entityManager.find(Employer.class, MICROSOFT.getId()));
}

编辑 3: 我终于弄清楚了发生了什么。我注意到在失败的测试中,日志中发布了SQL查询。通过微调我的log4j属性,我发现它们来自hibernate日志记录器,正如预期的那样。
但是成功的操作没有发布日志。这是因为它们没有到达数据库。一切都发生在实体管理器中,因此不需要SQL。现在我知道我只是遇到了我的H2数据库问题,我需要找出解决方法。
logging.level.org.hibernate.SQL=DEBUG logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
并查看? - Ahmed Raajlog4j.logger.org.hibernate=INFO
添加了部分日志,但是log4j.logger.org.hibernate.SQL=DEBUG
没有生效。你尝试过使用log4j.logger.org.hibernate=DEBUG
吗?或者上面有拼写错误吗? - dimwittedanimal
