将允许和不允许的URL规则追加到java中的列表

import java.util.ArrayList;
import java.util.List;

public class URLFilter {
    private List<String> allowList;
    private List<String> denyList;

    public URLFilter() {
        allowList = new ArrayList<>();
        denyList = new ArrayList<>();
    }

    public void addAllowRule(String urlPattern) {
        allowList.add(urlPattern);
    }

    public void addDenyRule(String urlPattern) {
        denyList.add(urlPattern);
    }

    public boolean isAllowed(String url) {
        for (String pattern : denyList) {
            if (url.matches(pattern)) {
                return false;
            }
        }
        for (String pattern : allowList) {
            if (url.matches(pattern)) {
                return true;
            }
        }
        return false;
    }
}

URLFilter filter = new URLFilter();
filter.addAllowRule("/public/*");
filter.addDenyRule("/admin/*");

String url1 = "/public/page1"; // 允许访问
String url2 = "/admin/page1"; // 不允许访问

System.out.println(filter.isAllowed(url1)); // 输出：true
System.out.println(filter.isAllowed(url2)); // 输出：false
