Question

我在将log4j 1.x升级到log4j2时面临以下错误。根据log4j2网站上的文档，我已经准备好了log4j2文件，但我仍然得到了这个例外。

Log4j2版本：2.6.1，Weblogic：10.3.6，jdk 1.7.x

请帮助解决此异常：

Log4j2.xml：

            <logger level="WARN" name="com.company.project.eligibility" />

</Configuration>

Answer 1

我想包装特定级别应该被注释掉或声明如下：

<Logger level="WARN" name="org.springframework" />
<Logger level="WARN" name="org.jboss" />
<Logger level="OFF" name="org.hibernate" />
<Logger level="WARN" name="com.company.project.eligibility" />

Answer 2

只有根记录器没有名称，因此此记录器需要具有名称：

<Logger level="DEBUG" includeLocation="true">
   <AppenderRef ref="FILE"/>
</Logger>

Log4j2为元素Logger提供的参数无效
