how to limit logging by calling method in spring logback

Question

I'm poor at writing in English. so sorry...

I want limit logging by method name base. and use class & method wildcard.

I want...

test.a.ClassA.java

public class ClassA {
  public static void methodA() {
    logger.debug("methodA called.");

    test.b.ClassB.methodB();
  }
}

test.b.ClassB.java

public class ClassB {
  public static void methodB() {
    logger.debug("methodB called.");

    test.c.ClassC.methodC();
  }
}

test.c.ClassC.java

public class ClassC {
  public static void methodC() {
    logger.debug("methodC called.");
  }
}

log-config.xml case 1 - start log, ClassB all method.

<logger start="test.b.ClassB.*" level="debug">
  <appender-ref ref="debugAppender"/>
</logger>

-- log output --
methodB called.
methodC called.
-- methodA not logged.

log-config.xml case 2 - start log, ClassC all method.

<logger start="test.c.ClassC.*" level="debug">
  <appender-ref ref="debugAppender"/>
</logger>

-- log output --
methodC called.
-- methodA not logged.
-- methodB not logged.

log-config.xml case 3 - start log, ClassB specific method only.

<logger start="test.c.ClassB.methodB" level="debug"">
  <appender-ref ref="debugAppender"/>
</logger>

-- log output --
methodB called.
methodC called.
-- methodA not logged.

log-config.xml case 4 - ClassB specific method only. not calling class, method logging

<logger only="test.c.ClassB.methodB" level="debug"">
  <appender-ref ref="debugAppender"/>
</logger>

-- log output --
methodB called.
-- methodA not logged.
-- methodC not logged.
