程序包装到EXE中包括log4j2，运行EXE软件时会发生错误

Question

由于POI依赖于log4j 2.7.1，因此已将log4j核和log4j-api添加到Maven中。将程序打包为JAR时没有错误。当使用EXE4J将JAR包装到EXE中时，会发生错误。 。首先，我认为log4j.xml配置文件并没有引起它，但是当我将log4j.xml放在资源文件夹中时，它仍然没有起作用。使用的开发环境是Win10 + Ecplise 2022-03 + JDK17。这是错误代码：

该错误表明它无法找到javax.naming.context，并且堆栈跟踪表示它是在log4j

我猜想您的记录配置（您不显示）包括$ {jndi：sometsing}。最简单的解决方案将是删除该查找（以及以$ {JNDI：开始开头的任何其他查找）。

您还可以在文档中查看EXE4J，以了解为什么不包括必要的类（这可能是java.naming.context）。

注意log4j版本2.7.1很容易受到log4shell的影响。您应该升级到您正在使用的Java版本的最新版本（请参阅这个）。
