copied!<p>It's possible to use two <code>Logger</code>s in one class. </p> <p>First idea: get the two loggers with different names:</p> <pre><code>package com.mycompany.apackage.MyClass; public class MyClass { private static final logger = Logger.getLogger(Myclass.class) private static final dbLogger = Logger. getLogger(Myclass.class.getName() + ".dblogger") } </code></pre> <p>Config for the package of the <code>dbLogger</code>:</p> <pre><code><root> <appender-ref ref="mainlog" /> </root> <logger name="com.mycompany.apackage.MyClass.dblogger"> <appender-ref ref="dbappender" /> </logger> </code></pre> <p>(Not tested.) In that case the <code>dbLogger</code> also logs to the <code>mainlog</code> appender. If it's not appropriate you could use a custom filter in the <code>mainlog</code> (and other) appenders which filters out the messages of the <code>dbLogger</code>. Another solution is using a completely different prefix for the <code>dbLogger</code>:</p> <pre><code> private static final logger = Logger.getLogger(Myclass.class) private static final dbLogger = Logger. getLogger("dblogger." + Myclass.class.getName()) </code></pre> <p>Log4j config:</p> <pre><code><root> </root> <logger name="com.mycompany"> <appender-ref ref="mainlog" /> </logger> <logger name="dblogger.com.mycompany"> <appender-ref ref="dbappender" /> </logger> </code></pre> <p>Note that if you pass the same parameter to the <code>getLogger()</code> method you will get same <code>Logger</code> object, so you have to use different names.</p>
