运行 由 shade 插件构建的独立应用程序时找不到 Log4j2 配置
Log4j2 configuration not found when running standalone application built by shade plugin
我有一个应用程序,当我从 maven log4j2 运行 运行它时:
mvn exec:java -Dexec.args=...
但是当我 运行 将 jar 作为独立应用程序时,它显示错误:
java -jar

我不明白这个错误。它显示找不到 log4j2 配置文件,但也抱怨配置文件中可能存在的某些格式
我的配置是:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="off">
<Appenders>
<Console name="console" target="SYSTEM_OUT">
<PatternLayout pattern="%d [%t] %-5p - %-26.26c{1} - %m\n" />
</Console>
</Appenders>
<Loggers>
<Root level="info">
<AppenderRef ref="console" />
</Root>
<Logger name="my.package" level="DEBUG" />
</Loggers>
</Configuration>
并且位于jar文件的根目录下。
更新
jar 由 maven shade 插件创建:
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
所以它包含所有必要的库(大约 23 MB),当我 运行 这个 jar 我只需要指定参数
好的,我发现这个 issue 关于这个问题。
简而言之,当使用maven shade插件将应用程序类打包到uber jar中时,就会出现问题。
虽然对于 log4j2
版本 2.8.1
修复仍然悬而未决,但建议的解决方法是使用阴影插件的额外配置设置更新 maven pom.xml
,如下所示:

除了@hudi给出的答案,
我们需要在插件中添加依赖项以进行转换。
