日志可以工作，但并不是您想要的，但P6Spy可以完美地工作。

这里有一个简单的教程来实现以及。对我来说，这就像魅力。

下载P6Spy库:获取P6Spy -install.jar 解压:解压p6spy-install.jar文件，查找p6spy.jar和spy.properties 添加库依赖项:将p6spy.jar添加到项目库依赖项中 Modify P6Spy properties file:修改数据库配置文件。您需要用P6Spy JDBC驱动程序替换现有的JDBC驱动程序。

原来是MySQL JDBC驱动程序- (com.mysql.jdbc.Driver)

<session-factory>
  <property name="hibernate.bytecode.use_reflection_optimizer">false</property>
  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>  <!-- note the difference -->
  <property name="hibernate.connection.password">password</property>
  <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/myuser</property>
  <property name="hibernate.connection.username">root</property>
  <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
  <property name="show_sql">true</property>
</session-factory>

更改为P6Spy JDBC驱动程序(com.p6spy.engine.spy.P6SpyDriver)

<session-factory>
  <property name="hibernate.bytecode.use_reflection_optimizer">false</property>
  <property name="hibernate.connection.driver_class">com.p6spy.engine.spy.P6SpyDriver</property>  <!-- note the difference -->
  <property name="hibernate.connection.password">password</property>
  <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/myuser</property>
  <property name="hibernate.connection.username">root</property>
  <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
  <property name="show_sql">true</property>
</session-factory>

修改P6Spy属性文件:spy.properties

用现有的MySQL JDBC驱动程序替换realdriver

realdriver=com.mysql.jdbc.Driver

# specifies another driver to use
realdriver2=
# specifies a third driver to use
realdriver3=

在logfile属性中更改日志文件的位置。所有SQL语句都将被记录到这个文件中。

窗口:

logfile=c:/spy.log

UNIX:

logfile=/srv/log/spy.log

复制的间谍。属性到项目类路径:复制间谍。属性添加到项目根文件夹。确保你的项目可以定位间谍。财产，否则就是间谍。属性文件未找到异常将被抛出。

使用YAML属性:

logging.level.org.hibernate:
    SQL: DEBUG
    type.descriptor.sql.BasicBinder: TRACE

如果您使用Spring Boot 3和/或Hibernate 6，以下配置将显示参数值:

# basic log level for all messages
logging.level.org.hibernate=info
# SQL statements and parameters
logging.level.org.hibernate.SQL=debug
logging.level.org.hibernate.orm.jdbc.bind=trace
# Statistics and slow queries
logging.level.org.hibernate.stat=debug
logging.level.org.hibernate.SQL_SLOW=info
# 2nd Level Cache
logging.level.org.hibernate.cache=debug

您需要配置如下:

# Hibernate logging options (INFO only shows startup messages)
log4j.logger.org.hibernate=INFO

# Log JDBC bind parameter runtime arguments
log4j.logger.org.hibernate.type=trace

我喜欢log4j:

log4j.logger.org.hibernate.SQL=trace
log4j.logger.org.hibernate.engine.query=trace
log4j.logger.org.hibernate.type=trace
log4j.logger.org.hibernate.jdbc=trace
log4j.logger.org.hibernate.type.descriptor.sql.BasicExtractor=error 
log4j.logger.org.hibernate.type.CollectionType=error
