我有一个Java应用程序,我已经使用Maven遮罩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没有从资源文件夹正确获取文件,因此抛出FileNotFoundException。JAR没有正确地使用资源(maven)
错误消息运行 'Java的罐子目标/ speech2code-1.0-快照fatjar.jar' 时:
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)
的我在哪里获取文件代码的行是:
File file = new File(getClass().getResource("/analyser/map.txt").getFile());
我的目录结构是(的map.txt是/src/main/resources/analyser/map.txt:
/src
/main
/java
/resources
/analyser
/map.txt
/test
我的POM文件:

任何帮助将不胜感激!
我认为你的问题是你正在使用'文件'..好吧,有点谷歌搜索,[阅读此](http://stackoverflow.com/questions/4548699/load-file-within-a-jar) 。 –
'File file = new File(getClass()。getResource(“/ analyzer/map.txt”)。getFile());'是访问嵌入式资源的错误方式,当嵌入时不是'File'引用在Jar里面,他们是Zip条目。你应该使用'getClass()。getResource(“/ analyzer/map.txt”)'得到'URL'引用或'getClass()。getResourceAsStream(“/ analyzer/map.txt”)' InputStream'参考资源 – MadProgrammer
谢谢你们,我花了2个小时搞清楚,你们在5分钟内告诉我。有用!谢谢:) – user3650664
