是否有一个API来获取类路径资源(例如我得到的Class.getResource(String))作为一个java.nio.file.Path？理想情况下,我想使用奇特的新Path API和类路径资源.

我必须将classpath资源从一个包复制到另一个包.

我的计划是:

    public static void main(String[] args) throws IOException, URISyntaxException {

            ClassLoader classLoader = CopyFileToDirectoryTest.class.getClassLoader();
InputStream in = classLoader.getResourceAsStream("com/stackoverflow/main/Movie.class");

            URI uri = ClassLoader.getSystemResource("com/stackoverflow/json").toURI();
            Path path = Paths.get(uri.getPath(),"Movie.class");
            System.out.println(path);

            long copy = Files.copy(in, path, StandardCopyOption.REPLACE_EXISTING);
            System.out.println(copy);

        }

在Files.copy方法我得到异常:

Exception in thread "main" java.nio.file.InvalidPathException: Illegal char <:> at index 2: /D:/Programs/workspaceEE/HibernateDemo/target/classes/com/stackoverflow/json
    at sun.nio.fs.WindowsPathParser.normalize(WindowsPathParser.java:182)
    at sun.nio.fs.WindowsPathParser.parse(WindowsPathParser.java:153)
    at sun.nio.fs.WindowsPathParser.parse(WindowsPathParser.java:77)

    at java.nio.file.Paths.get(Paths.java:84)
    at com.stackoverflow.main.CopyFileToDirectoryTest.main(CopyFileToDirectoryTest.java:34)

怎么解决？

解

public static void main(String[] args) throws IOException, URISyntaxException {
        ClassLoader classLoader = CopyFileToDirectoryTest.class.getClassLoader(); …
