如何使用Java创建Windows符号链接（到UNC路径）

Question

I am trying to create symbolic link of folder on my machine to the shared drive of other m/c

ie If I have 'test' folder in D drive. I want to create its Symbolic Link on shared folder say "\\\\hjds22\\Test". When I tried with below code it gives me java.nio.file.AccessDeniedException .

Code is given below:

        Path newLink =Paths.get( "\\\\hjds22\\Test\\newLink");
        Path target = Paths.get("D:\\test");
        try {
            Files.createSymbolicLink(newLink, target);
        } catch (IOException x) {
            System.err.println(x);
        } catch (UnsupportedOperationException x) {
            // Some file systems do not support symbolic links.
            System.err.println(x);
        }

Note: I have full rights on shared folder. I have also executed fsutil behavior set SymlinkEvaluation L2L:1 R2R:1 L2R:1 R2L:1 on both m/c's.

Answer 1

Runtime.getRuntime().exec("mklink /j dir target")

Answer 2

Windows shortcuts are not supported by Java.

You have to use an external library. Such as jShortcut , which comes with a jni dll.

This works very fine, except that the dll is a 32bits dll. And I (personaly) failed to compile it to 64bits. This will require to force your application to run with a 32bits jre.
