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>

Log4Jdbc插件最适合您的需求。它显示如下-
1. Complete SQL query being hit to the db
2. Parameter values being passed to the query
3. Execution time taken by each query
参考下面的链接来配置Log4Jdbc-

打开org.hibernate.type记录器，查看实际参数是如何绑定到问号的。
这里所有的答案我都有问题。它们实际上都没有为Spring Data JPA查询提供参数，该查询正在作为PK传递枚举。
对于Hibernate 5.3:

hibernate。Format_sql设置为true为漂亮的打印，这是我的输出示例:
17:00:00,664 [TRACE] Named parameters: {1=DE} [main] org.hibernate.engine.spi.QueryParameters.traceParameters(QueryParameters.java:325)
17:00:00,671 [DEBUG]
select
countrysub0_.code as code1_23_,
countrysub0_1_.country_subdivision as country_1_61_
from
country_subdivision countrysub0_
left outer join
jurisdiction_country_subdivision countrysub0_1_
on countrysub0_.code=countrysub0_1_.jurisdiction
where
countrysub0_.code=? [main] org.hibernate.engine.jdbc.spi.SqlStatementLogger.logStatement(SqlStatementLogger.java:103)
我尝试简单地将org.hibernate.engine.spi.QueryParameters设置为跟踪，但是由于某种原因，命名参数一直被禁用，所以我禁用了所有正在记录日志的其他内容。不过，它似乎没有记录所有参数，所以我仍然需要BasicBinding日志。
