iBatis, spring, how to log the sql that is executed?

Question

I am using iBatis with spring framework. I want to log the sql that iBatis executes when I say something like

Employee e = (Employee) getSqlMapClientTemplate().queryForObject("emp_sql", emp);

The above line will look for "emp_sql" id in the ibatis sql file that I have. And then run the query corresponding to "emp_sql". I want to log this query.

I have the following log4j xml properties file.

<appender name="sqlLogAppender" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="file" value="/disk1/logs/sql.log"/>
    <param name="datePattern" value="'-'yyyy-MM-dd'.txt'"/>
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%m %n"/>
    </layout>
   <filter class="org.apache.log4j.varia.LevelRangeFilter">
        <param name="LevelMin" value="DEBUG"/>
    </filter>
</appender>

<logger name="log4j.logger.com.ibatis">
    <level value="DEBUG"/>
    <appender-ref ref="sqlLogAppender"/>
</logger>


<logger name="log4j.logger.java.sql.Connection">
    <level value="DEBUG"/>
    <appender-ref ref="sqlLogAppender"/>
</logger>

<logger name="log4j.logger.java.sql.PreparedStatement">
    <level value="DEBUG"/>
    <appender-ref ref="sqlLogAppender"/>
</logger>

I still cannot get the sql that the ibatis executed. Is there something wrong with the configuration? Should I just say

<appender name="sqlLogAppender" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="file" value="/disk1/logs/sql.log"/>
    <param name="datePattern" value="'-'yyyy-MM-dd'.txt'"/>
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%m %n"/>
    </layout>
   <filter class="org.apache.log4j.varia.LevelRangeFilter">
        <param name="LevelMin" value="DEBUG"/>
    </filter>
</appender>

<logger name="log4j.logger.java.sql">
    <level value="DEBUG"/>
    <appender-ref ref="sqlLogAppender"/>
</logger>

Do I have to use p6spy or something else? Or is there something that I can do in the log4j configuration to get the iBatis sql logs?

Add the following to your log4j configuration (uncomment what you want to see).

# SqlMap logging configuration.
#log4j.logger.com.ibatis=DEBUG
#log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
#log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
#log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
#log4j.logger.java.sql=DEBUG
#log4j.logger.java.sql.Connection=DEBUG
#log4j.logger.java.sql.Statement=DEBUG
#log4j.logger.java.sql.PreparedStatement=DEBUG
#log4j.logger.java.sql.ResultSet=DEBUG
