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?

解决方案是正确的,但也记录结果对象的所有绑定。为了防止这种情况,可以创建一个单独的追加器并启用过滤。例如:
<!-- A time/date based rolling appender -->
<appender name="FILE_HIBERNATE" class="org.jboss.logging.appender.DailyRollingFileAppender">
<errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
<param name="File" value="${jboss.server.log.dir}/hiber.log"/>
<param name="Append" value="false"/>
<param name="Threshold" value="TRACE"/>
<!-- Rollover at midnight each day -->
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<layout class="org.apache.log4j.PatternLayout">
<!-- The default pattern: Date Priority [Category] Message\n -->
<param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>
</layout>
<filter class="org.apache.log4j.varia.StringMatchFilter">
<param name="StringToMatch" value="bind" />
<param name="AcceptOnMatch" value="true" />
</filter>
<filter class="org.apache.log4j.varia.StringMatchFilter">
<param name="StringToMatch" value="select" />
<param name="AcceptOnMatch" value="true" />
</filter>
<filter class="org.apache.log4j.varia.DenyAllFilter"/>
</appender>
<category name="org.hibernate.type">
<priority value="TRACE"/>
</category>
<logger name="org.hibernate.type">
<level value="TRACE"/>
<appender-ref ref="FILE_HIBERNATE"/>
</logger>
<logger name="org.hibernate.SQL">
<level value="TRACE"/>
<appender-ref ref="FILE_HIBERNATE"/>
</logger>

在Java中:
如果查询是CriteriaQuery (javax.persistence),则转换TypedQuery中的查询。
然后:
query.unwrap (org.hibernate.Query.class) .getQueryString ();
在使用Wildfly (standalone.xml)进行开发时,添加以下记录器:
<logger category="org.hibernate.SQL">
<level name="DEBUG"/>
</logger>
<logger category="org.hibernate.type.descriptor.sql">
<level name="TRACE"/>
</logger>
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
</layout>
</appender>
<logger name="org.hibernate" additivity="false">
<level value="INFO" />
<appender-ref ref="console" />
</logger>
<logger name="org.hibernate.type" additivity="false">
<level value="TRACE" />
<appender-ref ref="console" />
</logger>
将以下内容添加到log4j或logback配置中:
org.hibernate.sql=DEBUG
org.hibernate.type.descriptor.sql.BasicBinder=TRACE
