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

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。我改变了上面的代码,它使用InputStream。感谢MadProgrammer和Bagus Tesa!
