在Hibernate中是否有可能用真实值而不是问号打印生成的SQL查询?
如果无法使用Hibernate API,您会建议如何使用实际值打印查询?

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
其他回答
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
您可以在log4j.xml中添加类别行:
<category name="org.hibernate.type">
<priority value="TRACE"/>
</category>
并添加hibernate属性:
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">true</property>
如果你想让Hibernate用真实值而不是问号打印生成的SQL查询,请在Hibernate .cfg.xml/ Hibernate .properties中添加以下条目:
show_sql=true
format_sql=true
use_sql_comments=true
并在log4j.properties中添加以下条目:
log4j.logger.org.hibernate=INFO, hb
log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE
log4j.appender.hb=org.apache.log4j.ConsoleAppender
log4j.appender.hb.layout=org.apache.log4j.PatternLayout
<!-- A time/date based rolling appender -->
<appender name="FILE" class="org.apache.log4j.RollingFileAppender">
<param name="File" value="logs/system.log" />
<param name="Append" value="true" />
<param name="ImmediateFlush" value="true" />
<param name="MaxFileSize" value="200MB" />
<param name="MaxBackupIndex" value="100" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %d{Z} [%t] %-5p (%F:%L) - %m%n" />
</layout>
</appender>
<appender name="journaldev-hibernate" class="org.apache.log4j.RollingFileAppender">

将hibernate.cfg.xml修改为:
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">true</property>
在"log4j.properties"中包含log4j和以下条目:
log4j.logger.org.hibernate=INFO, hb
log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE
log4j.appender.hb=org.apache.log4j.ConsoleAppender
log4j.appender.hb.layout=org.apache.log4j.PatternLayout
