我有一個Java應用程序,我已經使用Maven遮罩插件將它捆綁到一個JAR文件中。出於某種原因,當我從target /運行JAR文件時,JAR沒有從資源文件夾正確獲取文件,因此拋出FileNotFoundException。JAR沒有正確地使用資源(maven)

錯誤消息運行 'Java的罐子目標/ speech2code-1.0-快照fatjar.jar' 時:

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) 

的我在哪裏獲取文件代碼的行是:

File file = new File(getClass().getResource("/analyser/map.txt").getFile()); 

我的目錄結構是(的map.txt是/src/main/resources/analyser/map.txt:

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

我的POM文件:

我認爲你的問題是你正在使用'文件'..好吧,有點谷歌搜索,[閱讀此](http://stackoverflow.com/questions/4548699/load-file-within-a-jar) 。 –

'File file = new File(getClass()。getResource(「/ analyzer/map.txt」)。getFile());'是訪問嵌入式資源的錯誤方式,當嵌入時不是'File'引用在Jar裏面,他們是Zip條目。你應該使用'getClass()。getResource(「/ analyzer/map.txt」)'得到'URL'引用或'getClass()。getResourceAsStream(「/ analyzer/map.txt」)' InputStream'參考資源 – MadProgrammer

所以我應該使用InputStream來讀取資源,而不是將其轉換爲Java中的文件。我改變了上面的代碼,它使用InputStream。感謝MadProgrammer和Bagus Tesa!
