log4j2-错误 Appender 包含无效元素或属性“Flume”

Question

我正在尝试使用log4j2的Flume Appender Properties。但是运行程序时出现以下错误。

  2016-01-20 16:36:42,436 main ERROR Appenders contains an invalid element or attribute "Flume"
    2016-01-20 16:36:42,436 main ERROR Appenders contains an invalid element or attribute "Flume"
    2016-01-20 16:36:42,446 main ERROR Unable to locate appender "eventLogger" for logger config "root"
    2016-01-20 16:36:42,446 main ERROR Unable to locate appender "eventLogger" for logger config "root"

log4j.xml 文件是：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
  <Appenders>
    <Console name="Console" target="SYSTEM_OUT">
        <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
    </Console>
    <Flume name="eventLogger" compress="false" type="Avro">
        <Agent host="192.168.8.50" port="41414"/>
    </Flume>
  </Appenders>
  <Loggers>
    <Root level="info">
        <AppenderRef ref="Console" />
        <AppenderRef ref="eventLogger" />
    </Root>
  </Loggers>
</Configuration>

在 .java 代码中

LoggerContext context = (org.apache.logging.log4j.core.LoggerContext) LogManager.getContext(false);
File file = new File("src/log4j2.xml");
context.setConfigLocation(file.toURI());

我如何找出问题所在。可能是 log4j2 无法正常工作。

Answer 1

我遇到了类似的情况，即使Appender元素在Appenders下也无法识别。修复方法是在配置中添加 strict = "true"，如下所示

配置状态=“警告”严格=“true”

Answer 2

你的类路径中有 log4j Flume jar 吗？如果将状态设置为调试，您应该会看到更多信息。
