如何在log4j.xml中设置过滤器 [英] How to set filter in the log4j.xml

问题描述

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.这不是我们所必需的.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?

In our web application it prints all the logs are printed like Spring and JSF jars files. Which not required for us. How can I set in the log4j.xml file to filter only for our application?

已更新

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?我必须在文件中添加logger元素的地方?

The following is the configuration we are using for the logging. Can you please tell me whether it is correct? Where I have to add the logger element in the file?

推荐答案

仅记录Spring警告:

Log only warning for Spring :

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

与jsf软件包名称的JSF相同... javax.faces，org.apache.myfaces，com.sun.faces等...，appender-ref指向您的appender ...

Same for JSF with the jsf package name... javax.faces, org.apache.myfaces, com.sun.faces etc... also, the appender-ref refers to your appenders...
