Question

我有一个java应用程序，我使用maven shade插件将它捆绑到一个JAR文件中。出于某种原因，当我从target /运行JAR文件时，JAR没有从resources文件夹中正确获取文件，因此抛出了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/analyser/map.txt：

/src
    /main
        /java
        /resources
               /analyser
                   /map.txt
    /test

我的POM文件：

<project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

任何帮助将不胜感激！

Answer 1

所以我应该使用InputStream来读取资源，而不是将其转换为Java中的File。我更改了上面的代码，它使用InputStream。感谢MadProgrammer和Bagus Tesa！

JAR没有正确使用资源（maven）
