我正在尝试在log4j中实现套接字附加器，以便将我的日志直接写入主机应用程序。
下面是我的log4j配置，
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="trace" monitorInterval="5">
<Appenders>
<Socket name="socket" host="localhost" port="8085" reconnectDelayMillis="30000" protocol="TCP" immediateFlush="true">
<PatternLayout></PatternLayout>
</Socket>
<Async name="SplunkAsync">
<AppenderRef ref="socket"/>
</Async>
</Appenders>
<Loggers>
<Root level="warn">
<AppenderRef ref="SplunkAsync"/>
</Root>
<Logger name="org.mule.module.http.internal.HttpMessageLogger" level="debug" additivity="false">
<AppenderRef ref="SplunkAsync"/>
</Logger>
</Loggers>
</Configuration>我也尝试过从java程序向这个本地主机8085端口发送消息，它工作得非常好。
但是使用log4j附加器，我得到了下面的异常，
原因: java.io.IOException:长度1279873876超出限制: 26

查看类名org.mule.module.http.internal.HttpMessageLogger，您会看到一个.internal。包。这是一个强烈的提示，表明您根本不应该使用该包。
发生的情况是，您正在使用内部Mule实现类作为Splunk的Log4j2自定义附加。在任何情况下，这都不是该类的预期用途。
您应该做的是查看Splunk documentation并遵循其中的步骤。
