Parsing URL into components

问题:

I want to parse a descriptive-style URL with slashes (such as server/books/thrillers/johngrisham/thefirm), in Java.

My overall idea is to handle the data I receive to do a lookup (therefore using the URL as search criteria) in a database and then return HTML pages with data on it.

How do I do this?

回答1:

String urlToParse = "server/books/thrillers/johngrisham/thefirm";
String[] parsedURL = urlToParse.split("/");

What you will have is an array of strings that you can then work with.

// parsedURL[0] == "server";
// parsedURL[1] == "books";
// parsedURL[2] == "thrillers";
// parsedURL[3] == "johngrisham";
// parsedURL[4] == "thefirm";

回答2:

The split() method of String class can do the work, as commented Ionut before.
