我有一个 Java 应用程序，我已使用 Maven Shade 插件将其捆绑到 JAR 文件中。由于某种原因，当我从 target/运行 JAR 文件时，JAR 无法从资源文件夹中正确获取文件，从而引发 FileNotFoundException。
运行“java -jar target/speech2code-1.0-SNAPSHOT-fatjar.jar”时出现错误消息:
java.io.FileNotFoundException: file:/Users/mb/Desktop/Speech2Code-IDE/speech2code/target/speech2code-1.0-SNAPSHOT-fatjar.jar!/analyser/map.txt (No such file or directory)
我获取文件的代码行是:
File file = new File(getClass().getResource("/analyser/map.txt").getFile());
我的目录结构是(map.txt位于/src/main/resources/analysisr/map.txt中:
/src
/main
/java
/resources
/analyser
/map.txt
/test

任何帮助将不胜感激!
最佳答案
所以我应该使用InputStream 来读取资源，而不是将其转换为Java 中的文件。我更改了上面的代码，它可以使用 InputStream 运行。感谢 MadProgrammer 和 Bagus Tesa!
