logging hibernate parameter values using logback and slf4j

Question

I use hibernate, spring mvc, and eclipse. In my eclipse console, the hibernate sql displays in the form of:

Hibernate: insert into some_table (fieldname1, fieldname2, fieldname3, fieldname4)  
values (?, ?, ?, ?)

How can I get the console to print out the values that are being inserted in the place of the question marks? I am committed to using slf4j and logback for the logging in my app.

Here is my logback.xml:

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="30 seconds">

    <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
        <resetJUL>true</resetJUL>
    </contextListener>

    <!-- To enable JMX Management -->
    <jmxConfigurator/>

    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%-5level %logger{0} - %msg%n</pattern>
        </encoder>
    </appender>

    <!--<logger name="org.hibernate" level="debug"/> -->
    <logger name="mypackagename.myappname" level="debug"/>
    <logger name="org.hibernate.SQL" additivity="false" level="DEBUG" />
    <logger name="org.hibernate.type" additivity="false" level="TRACE" />

    <root level="info">
        <appender-ref ref="console"/>
    </root>
</configuration>

The correct working answer turned out to be:

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="30 seconds">

    <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
        <resetJUL>true</resetJUL>
    </contextListener>

    <!-- To enable JMX Management -->
    <jmxConfigurator/>

    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%-5level %logger{0} - %msg%n</pattern>
        </encoder>
    </appender>

    <logger name="mypackagename.myappname" level="TRACE"/>
    <logger name="org.hibernate.SQL" level="DEBUG" />
    <logger name="org.hibernate.type" level="TRACE" />

    <root level="info">
        <appender-ref ref="console"/>
    </root>
</configuration>
