Question

我正在开发一个将log4j2作为传递依赖项的项目。我有这个错误

ERROR StatusLogger找不到log4j2配置文件。使用默认值配置：仅将错误记录到控制台。

所以我在src / main / resources下创建了一个新的log4j2.xml文件，并尝试使用Default Apache的配置。

这里：

<?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>
  </Appenders>
  <Loggers>
    <Root level="error">
      <AppenderRef ref="Console"/>
    </Root>
  </Loggers>
</Configuration>

现在，当我构建项目时，警告（错误）提示：

目前的依赖版本：

log4j2 Dependencies

可能导致这种情况的原因是什么？

提前致谢。

Juan c：

Answer 1

这不是问题。 Interpolator类正在尝试启用各种查找：例如，env:propertyName查找环境变量，sys:propertyName查找Java系统属性，jndi:propertyName查找JNDI属性等。< / p>

如果JNDI不可用，您将看到此警告。记录此消息后，配置将继续。

您可以在log4j2 Jira问题跟踪器上发出请求，使其看起来不像是错误（事后看来，堆栈跟踪在这里是混乱和不必要的。）

Answer 2

也许该项目还会在某处依赖于JMX属性加载另一个log4j2配置。您可以通过在配置文件上启用DEBUG或TRACE状态来获取有关Log4j正在执行的操作的更多信息，如here所示

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG" name="example-config">
</Configuration>

还可以通过在运行应用程序时传入系统属性来尝试将Log4j的默认StatusLogger设置为DEBUG：

java -DLog4jDefaultStatusLevel=DEBUG MyApp

另外，你确定类路径中没有1.2依赖项吗？如果有，它们可能与1.2-2.1桥相冲突。

传递log4j2依赖 - 配置失败
