我正在尝试使用外部配置文件制作 jar 文件。在使用 poi-ooxml 库之前一切正常。之后我遇到了资源提供的问题。我使用下一个 pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

</dependency>

</project>
我在这一行失败了:
LogManager.getLogManager().readConfiguration(MethodHandles.lookup().lookupClass().getClassLoader().getResourceAsStream(fileName));
getResourceAsStream 返回 null，但是当我从 pom 文件中删除 poi-ooxml 依赖项时，一切正常。
最佳答案
问题出在 Apache Assembly 插件中。请改用 Apache Shade 插件。 https://maven.apache.org/plugins/maven-shade-plugin/
关于java - 使用 poi-ooxml 破坏了资源提供，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39510759/
