Hibernate show_sql

Question

Hello Ivy-Team,

how can I configurate the hibernate.show_sql property? I tried to configurate it in the persistence configuration editor but nothing happened. Is there something else I have to do?

Thanks for answers alt text

Accepted Answer

I guess that you have to customize the log4j configuration so that the hibernate logs are visible in the designer log. To do so open the file [designer-root-dir]/configuration/log4jconfig.xml with a text editor.

Add a category to define the hibernate sql log level right below an existing category definition:

  <category name="org.hibernate.SQL" class="ch.ivyteam.log.Logger">
    <priority value="WARN"/><!-- raised priority so that we see the logs with a default designer configuration -->
  </category>

Restart you Designer to apply the changed log configuration.

For a list of available loggers consult the hibernate documentation: https://docs.jboss.org/hibernate/orm/3.3/reference/en-US/html/session-configuration.html#configuration-logging

Notice that with the Axon.ivy Visual VM plugin you can also inspect the sql queries that are fired by the hibernate persistence layer. In contrast to the normal log outputs you will also see execution times and the used runtime parameters on for parameterized queries. See the "external database" tab in the plugin: http://developer.axonivy.com/doc/latest/EngineGuideHtml/monitoring.html#d5e4726

Hello all,

I have tried with the solution form Reguel but it doesn't work. Pls help me if you have any idea!

Thanks!

In the persistence.xml, I had added the property for show sql:


<property name="hibernate.show_sql" value="true"/>

This is my log4jconfig.xml:







<log4j:configuration debug="false" xmlns:log4j="http://jakarta.apache.org/log4j/">
 
  <appender name="FileLog" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="Threshold" value="INFO"/>
    <param name="File" value="${user.dir}/logs/ch.ivyteam.ivy.log"/>
    <param name="DatePattern" value="'.'yyyy-MM-dd"/>
    <layout class="org.apache.log4j.IvyLog4jLayout">
      <param name="DateFormat" value="HH:mm:ss.SSS"/>
    </layout>
  </appender>


  <appender name="ConsoleAppender" class="org.apache.log4j.ConsoleAppender">
    <param name="Threshold" value="WARN"/>
    <layout class="org.apache.log4j.IvyLog4jLayout">
      <param name="DateFormat" value="HH:mm:ss.SSS"/>
      <param name="ContextPrinting" value="false"/>
      <param name="FixedCategoryLength" value="20"/>
      <param name="ThreadPrinting" value="false"/>
    </layout>
  </appender>

  <category name="org.apache.cxf.bus.spring" class="ch.ivyteam.log.Logger">
    <priority value="ERROR"/>
  </category>
<category name="org.hibernate.SQL" class="ch.ivyteam.log.Logger">
    <priority value="INFO"/>
  </category>

  

   <root> 
    <level value="INFO"/>
    <appender-ref ref="FileLog"/>
    <appender-ref ref="SmsLog"/> 
    <appender-ref ref="EmailLog"/> 
    <appender-ref ref="ConsoleAppender"/>
  </root>
</log4j:configuration>

Hello Hapem85,

try to create your own hibernate appender:

<appender name="hibernate-appender" class="org.apache.log4j.RollingFileAppender">
    <param name="Append" value="true"/>
    <param name="File" value="${user.dir}/logs/hibernate.log"/>
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="[%d{dd/MM/yy} %d{HH:mm:ss}] %-5p %c %m%n"/>
    </layout>
</appender>

and change the category to logger:

<logger name="org.hibernate.SQL">
    <appender-ref ref="hibernate-appender"/>
    <level value="DEBUG"/>
</logger>

Hope that helps.
