从.jar文件夹中读取文件 [英] Read a file from inside the .jar folder

问题描述

我需要以这种方式读取jar文件夹中的文件:

I need to read the file, that is inside the jar folder in this way:

 DataSource coverdata = new FileDataSource(new File("here is the path"));

如何获取确切路径?我正在使用一个库，因此访问文件的唯一方法是new File()，没有输入流.

How do I get the exact path? I am using a library, so the only way I can acces file is new File(), no inputstreams.

推荐答案

调用ClassLoader.getResourceAsStream()::InputStream或ClassLoader.getResource()::URL.

请参阅:

http://download.oracle.com/javase/1.5.0/docs/api/java/lang/ClassLoader.html#getResourceAsStream(java.lang.String )

包含请求文件的JAR文件必须在类路径中.

The JAR file containing the requested file must be in the classpath.
