从jar中获取资源 [英] Get resource from jar

问题描述

我有 jar 文件:

myJar/res/endingRule.txt
myJar/wordcalculator/merger/Marge.class

在 Marge.java 中，我有代码:

In Marge.java I have code:

private static final String ENDINGS_FILE_NAME = "res/endingRule.txt";
....
InputStream inputStream  = getClass().getClassLoader().getResourceAsStream(ENDINGS_FILE_NAME);
.....

但是在此 inputStream 之后为空.如何使用资源?为什么为空?

But after this inputStream is null. How to work with resources? Why null?

推荐答案

要检索 jar 中的文件，请使用:

To retrieve the file inside the jar, use:

private static final String ENDINGS_FILE_NAME = "/res/endingRule.txt";
...
InputStream is = getClass( ).getResourceAsStream(ENDINGS_FILE_NAME);
