当我在intellij Idea中运行main方法时，我的项目中有log4j 2，它正确地打印日志。
当我使用maven-shade-plugin包项目到jar文件，并运行jar作为独立的应用程序时，它显示错误：
java -cp软件包. jar com.xxx.testMain
控制台输出

pom.xml配置。log4j2.version = 2.10.0， Spring Boot 版本为1.5.9。发布

如果一个依赖项包含log4j2插件，那么jar中会包含一个Log4j2Plugins.dat缓存文件。当使用Maven shade插件将多个jar与一个Log4j2Plugins.dat文件合并时，只有一个jar会保留下来。如果没有插件定义，启动时会显示错误。Log4j2 issue
一个解决方案是从shaded jar中排除Log4j2Plugins.dat缓存文件，这样Log4j在启动时会扫描插件。为此，在pom的maven-shade-plugin配置中添加一个过滤器：

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.1.0</version>
        <configuration>
            <createDependencyReducedPom>false</createDependencyReducedPom>
            <filters>
                <filter>
                    <artifact>*:*</artifact>
                    <excludes>
                        <exclude>**/Log4j2Plugins.dat</exclude>
                    </excludes>
                </filter>
            </filters>
        </configuration>
        ...
    </plugin>

另一个解决方案是使用transformation plugin合并该高速缓存文件，transformation plugin是log4j版本特定的。

如果您使用的是Gradle和ShadowJar 4+：

shadowJar{
  transform(com.github.jengelman.gradle.plugins.shadow.transformers.Log4j2PluginsCacheFileTransformer)
}

GradleKotlin数字用户线：

shadowJar {
    transform(com.github.jengelman.gradle.plugins.shadow.transformers.Log4j2PluginsCacheFileTransformer::class.java)
}

不幸的是，我无法回复Shashank Kapoor的回答，因为他正确地指出，排除Log4j2Plugins.dat文件可以解决问题。

shadowJar {
    exclude "**/Log4j2Plugins.dat"
}

当人们在类路径上有多个版本的Log4j2时，我以前见过这个错误。

对于我们这些从类路径中删除旧的Logj 42以修复Log 4Shell（CVE-2021-44228）漏洞的人来说，您可能会发现在升级后使用Uber jar时会遇到此问题。
如果您正在从Maven或Gradle构建您的Uber jar，请分别使用其中一个插件：

Maven：https://maven.apache.org/plugins/maven-shade-plugin/与https://github.com/edwgiz/maven-shaded-log4j-transformer搭配使用
等级：https://plugins.gradle.org/plugin/com.github.johnrengelman.shadow

如果你是通过其他方式构建的，请看下面的答案：https://stackoverflow.com/a/70497498/1174024。但基本上您必须像此类一样正确处理Log4j 2插件缓存文件：
https://github.com/edwgiz/maven-shaded-log4j-transformer/blob/master/src/main/java/io/github/edwgiz/log4j/maven/plugins/shade/transformer/Log4j2PluginCacheFileTransformer.java
以在构建新的uber jar时正确处理Log4j2Plugins.dat文件。
