带有ExpressionFilter的log4j 1.2筛选器异常

Question

我使用的是log4j1.2.17，我想从日志中过滤一些异常，在尝试了很多人员后，我没有得到预期的结果。这是我想要过滤的异常，通常不会显示在日志控制台中：

2020-02-26 11:04:50,470 ERROR [worker #1] com.myPackage.myClass: Access denied
com.myPackage.myClass.model.RestException: Access denied

at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)
at java.lang.reflect.Method.invoke(Unknown Source)

这是我的log4j.xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/xml/doc-files/log4j.dtd">

</filter>
</appender>
<root>
<priority value="DEBUG" />
<___priority value="INFO" />
<appender-ref ref="file"/>
<appender-ref ref="console"/>
</root>
</log4j:configuration>

我也试过<param name="Expression" value="EXCEPTION ~= 'com.myPackage.myClass: Access denied'"/>

<param name="Expression" value="EXCEPTION ~= 'com.myPackage.myClass.model.RestException: Access denied'"/>

但我的日志中仍然存在"拒绝访问"异常

Answer 1

经过更多的研究，我更改了类过滤器来自："org.apache.log4j.filter.ExpressionFilter"至："org.apache.log4j.varia.StringMatchFilter"它工作得很好，现在它从我的日志中隐藏了这个异常

<filter class="org.apache.log4j.varia.StringMatchFilter">
<param name="StringToMatch" value="Access denied"/>
<param name="AcceptOnMatch" value="false"/>
</filter>
