传递性 log4j2 依赖 - 配置失败
Transitive log4j2 dependency - configuration failing
我正在处理一个将 log4j2 作为传递依赖项的项目。
我遇到了这个错误
ERROR StatusLogger No log4j2 configuration file found. Using default
configuration: logging only errors to the console.
所以我在 src/main/resources 下创建了一个新的 log4j2.xml 文件，并尝试使用默认的 Apache 配置。
此处：
<?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，当我构建我的项目时，这个 warns（错误）提示：

当前依赖版本：
这可能是什么原因造成的？
提前致谢。
胡娟：
也许该项目还在某处加载了另一个依赖于 JMX 属性的 log4j2 配置。您可以通过在您的配置文件上启用 DEBUG 或 TRACE 状态来获取有关 Log4j 正在做什么的更多信息，如图所示 here
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG" name="example-config">
</Configuration>
还尝试通过传入系统 属性 将 Log4j 的默认 StatusLogger 设置为 DEBUG，当 运行 应用程序时：
java -DLog4jDefaultStatusLevel=DEBUG MyApp
此外，您确定类路径中没有 1.2 依赖项吗？如果有，它们可能与 1.2-2.1 桥冲突。
这不是问题。 Interpolator class 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 用于 JNDI 属性等
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 问题跟踪器上提出请求，使这看起来不像是错误（事后看来，堆栈跟踪在这里令人困惑且不必要）。
我正在处理一个将 log4j2 作为传递依赖项的项目。 我遇到了这个错误
ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.
所以我在 src/main/resources 下创建了一个新的 log4j2.xml 文件，并尝试使用默认的 Apache 配置。
此处：
<?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>

当前依赖版本：
这可能是什么原因造成的？
提前致谢。
胡娟：
也许该项目还在某处加载了另一个依赖于 JMX 属性的 log4j2 配置。您可以通过在您的配置文件上启用 DEBUG 或 TRACE 状态来获取有关 Log4j 正在做什么的更多信息，如图所示 here
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG" name="example-config">
</Configuration>
还尝试通过传入系统 属性 将 Log4j 的默认 StatusLogger 设置为 DEBUG，当 运行 应用程序时：
java -DLog4jDefaultStatusLevel=DEBUG MyApp
此外，您确定类路径中没有 1.2 依赖项吗？如果有，它们可能与 1.2-2.1 桥冲突。
这不是问题。 Interpolator class 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 用于 JNDI 属性等
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 问题跟踪器上提出请求，使这看起来不像是错误（事后看来，堆栈跟踪在这里令人困惑且不必要）。
