如何使用相对路径获取 URL？

Question

I have a URL:

URL url=new URL("https://example.com/aa/bb/cc/file.html");

and a relative path:

String relativePath="../file2.html"; //maybe is "/file3.html"

I want to get http://example.com/aa/bb/file2.html using variable url and relativePath

How to do it?

Answer 1

new URL(url, relativePath);

Answer 2

如果要构建指向相关文件的 URL，可以使用：

URL url = new URL(new URL("file:"), "./myLocalFile.txt");

Answer 3

Try operating winth the class URI instead of the URL .

To get the URI from your URL:

java.net.URI anURI=url.toUri();

Then, to resolve the relative URI:

URI resultURI=anURI.resolve(relativePath);

And at last, to get an URL type use de method toUrl() of the URI result variable, and you've got it.

Answer 4

When building relative URL, keep in mind that the base is path to current package, not file. I mean: the referer file is in .../myProject/src/pckg/javafile.java and the referated file is in .../myProject/some-other/nice.file , then the relative reference should look like this:

URL url = new URL(new URL("file:"), "./../some-other/nice.file");

and this works for me as well:

URL url = new URL("file:./../some-other/nice.file");

Answer 5

我发现有效的是：

new URL("file:./src/gui/Something.fxml")

Answer 6

这适用于我的代码
URL url=Myclass.class.getResource("/com/fnf/si/DepAcctInq_V02.wsdl");
