public class RedirectUrlUtil {

    public static String getRedirectUrl(String url) throws IOException {
        HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
        connection.setInstanceFollowRedirects(true);
        connection.connect();

        int responseCode = connection.getResponseCode();
        if (responseCode == HttpURLConnection.HTTP_MOVED_PERM || responseCode == HttpURLConnection.HTTP_MOVED_TEMP) {
            String redirectUrl = connection.getHeaderField("Location");
            return redirectUrl;
        }

        return url;
    }
}

try {
    String redirectUrl = RedirectUrlUtil.getRedirectUrl("http://example.com");
    // 处理重定向后的URL
    // ...
