Question

我正在尝试在log4j中实现套接字附加程序，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>

我还尝试了从Java程序向此localhost 8085端口发送消息的方法，效果很好。

但是使用log4j追加器，我得到下面的异常，

原因：java.io.IOException：长度1279873876超出限制：26

Answer 1

查看类名称org.mule.module.http.internal.HttpMessageLogger，您会看到一个.internal。包。这有力地暗示了您根本不应该使用该软件包。

正在发生的事情是，您正在使用内部Mule实现类作为为Splunk附加的Log4j2自定义。在任何情况下，这都不是该类的预期用法。

您应该做的是看Splunk documentation并按照那里的步骤进行操作。

由以下原因引起：java.io.IOException：长度1279873876超出限制：26
