Logback/Weblogic如何设置不同的日志级别？

Question

我使用的是WebLogic10.3.6，我不能用给定的logback.xml为2个不同的追加器(com.my&root)控制不同的日志级别，我只希望文件追加器有跟踪级别，而在Weblogic终端下没有任何跟踪级别。问题是我在这两个方面得到相同的输出。

我想说设置可加性标志会对您有所帮助：

xml prettyprint-override"><logger name="com.my" level="trace" additivity="false">
    <appender-ref ref="file" />
</logger>
