log4j:ERROR尝试附加到名为[..]的封闭附加程序 [英] log4j:ERROR Attempted to append to closed appender named [..]

问题描述

我反复在控制台上出现以下错误

I am getting following errors on my console repeatedly

log4j:ERROR Attempted to append to closed appender named [ConsoleAppender].
log4j:ERROR Attempted to append to closed appender named [FixedWindowRollingFile].

使用的log4j.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

        </layout>
    </appender>

    <appender name="ConsoleAppender" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.SimpleLayout"/>
    </appender>

    <logger name="com.arosys" additivity="false" >
        <level value="INFO" />
        <appender-ref ref="ConsoleAppender" />
        <appender-ref ref="FixedWindowRollingFile"/>
    </logger>

    <root>
        <priority value="INFO"/>
        <appender-ref ref="ConsoleAppender"/>
        <appender-ref ref="FixedWindowRollingFile"/>
    </root>
</log4j:configuration>

推荐答案

我在这里回答了类似的问题: https: //stackoverflow.com/a/9973283/340290

对于我来说，我有两个Log4j.properties可供Log4J使用:一个是通过将其放在类路径中，另一个是通过编程方式加载(使用PropertyConfigurator.configure(..)).

In my case, I've two log4j.properties available to the Log4J: one via placing it in classpath and other being loaded programmatically (using PropertyConfigurator.configure(..)).

在这两个文件中，我已经用相同的名称stdout注册了ConsoleAppender，并且两次用于同一类别(每个属性文件一个).删除配置或属性文件解决了我的问题.

And in the two files, I've ConsoleAppender registered with same name stdout and used for same category twice (one per each properties file). Removing config or the properties file solved my issue.
