如何在log4j.xml中设置过滤器

HI,

在我们的 Web 应用程序中，它打印所有日志，就像 Spring 和 JSF jar 文件一样。这对我们来说不是必需的。如何在 log4j.xml 文件中设置为仅针对我们的应用程序进行过滤？

Updated

以下是我们用于日志记录的配置。你能告诉我这是否正确吗？我必须在文件中的哪里添加记录器元素？

仅记录 Spring 的警告：

<logger name="org.springframework">
    <level value="warn"/>
    <appender-ref ref="socket"/>
    <appender-ref ref="stdout"/>
</logger>

对于具有 jsf 包名称的 JSF 来说也是如此...javax.faces, org.apache.myfaces, com.sun.faces等等...此外，appender-ref 指的是您的appender...
