在java中打开具有相对路径的资源
问题描述：
在我的Java应用程序中，我需要获取一些文件和目录。
In my Java app I need to get some files and directories.
这是程序结构：
./main.java
./package1/guiclass.java
./package1/resources/resourcesloader.java
./package1/resources/repository/modules/ -> this is the dir I need to get
./package1/resources/repository/SSL-Key/cert.jks -> this is the file I need to get
guiclass 加载将加载我的资源（目录和文件）的resourcesloader类。
guiclass loads the resourcesloader class which will load my resources (directory and file).
关于文件，我试过
resourcesloader.class.getClass().getResource("repository/SSL-Key/cert.jks").toString()
以获得真实路径，但这种方式不起作用。
in order to get the real path, but this way does not work.
我没有想法如何做目录。
I have no idea how to do the directory.
答
提供相对于类加载器的路径，而不是你从中获取加载器的类。例如：
Supply the path relative to the classloader, not the class you're getting the loader from. For instance:
resourcesloader.class.getClassLoader().getResource("package1/resources/repository/SSL-Key/cert.jks").toString();
