如何在Hibernate日志中显示SQL参数？ [英] How to show SQL parameters in Hibernate log?

问题描述

在我的hibernate.cfg.xml中，我有以下内容：

In my hibernate.cfg.xml, I have the following:

<property name="show_sql">true</property>

在我的log4j.xml中，我有以下内容：

In my log4j.xml, I have the following:

<logger name="org.hibernate" additivity="false">
    <level value="TRACE"/>
    <appender-ref ref="hbn_log"/>
</logger>

<category name="org.hibernate.SQL" additivity="false">
    <priority value="TRACE"/>
    <appender-ref ref="hbn_log"/>
</category>

<category name="org.hibernate.type" additivity="false">
    <priority value="TRACE"/>
    <appender-ref ref="hbn_log"/>
</category>

<logger name="org.hibernate.type.descriptor.sql.BasicBinder"> 
    <level value="TRACE"/>
    <appender-ref ref="hbn_log"/>
</logger>

<logger name="org.hibernate.event.def.DefaultLoadEventListener" additivity="true">
    <level value="all"/>
    <appender-ref ref="hbn_log"/>
</logger>

<logger name="org.hibernate.cache.ReadWriteCache" additivity="true">
   <level value="all"/>
   <appender-ref ref="hbn_log"/>
</logger>

<appender name="hbn_log" class="com.adventnet.management.log.NMSRollingFileAppender">
   <param name="File" value="logs/hbn.txt"/>
       <param name="MaxFileSize" value="1MB"/>
       <param name="MaxBackupIndex" value="10"/>
   <layout class="org.apache.log4j.PatternLayout">
                 <param name="ConversionPattern" value="[%d{dd MMM yyyy HH:mm:ss:SSS}] %-5c{2}: %m%n"/>
   </layout>
   <param name="Threshold" value="TRACE"/>
</appender>

在我的stdout.txt中，我可以看到它记录了SQL语句：

In my stdout.txt, I can see that it logs the SQL statement:

[13 Apr 2013 22:03:59:199] SYS_OUT: Hibernate: select this_.EMSID as EMSID195_0_, this_.COUNTER as COUNTER195_0_, this_.TIMESTAMP as TIMESTAMP195_0_, this_.UPDATETYPE as UPDATETYPE195_0_, this_.OBJECTTYPE as OBJECTTYPE195_0_, this_.OBJECTID as OBJECTID195_0_, this_.OBJECT as OBJECT195_0_ from WebNmsDB.UpdateData this_ where this_.EMSID=?

但我希望它也记录SQL的参数，并且不会显示它。

But I want it to also log the parameter for the SQL, and it's not showing it.

另一件事是，appender被定义为记录到hbn.txt，但是SQL语句被记录到stdout.txt而不是hbn.txt。

Another thing is that the appender is defined to log to hbn.txt, but the SQL statement gets logged to stdout.txt and not hbn.txt. I don't know why that's happening.

推荐答案

在log4j.xml中追加这个配置

Append this config on your log4j.xml

<logger name="org.hibernate.type.descriptor.sql.BasicBinder"> 
    <level value="TRACE"/>
</logger>

不要忘记检查您的appender的Threadhold级别。

Don't forgot to check your appender's Threadhold level.
