Java简单通配符匹配

Question

我正在创建一个java IRC lib，我需要一个方法来查看某个用户是否匹配可以包含通配符*字符的主机掩码。在不使用正则表达式的情况下，最简单的方法是什么？

一些例子：

    // Anything works
    *
            server.freenode.net ✔

    // Any nickname/user/host works
    *!*@*:
            any!thing@works ✔

    // Any nickname works (may have multiple nicknames on the same user)
    *!nebkat@unaffiliated/nebkat:
            nebkat!nebkat@unaffiliated/nebkat ✔
            123456!nebkat@unaffiliated/nebkat ✔
            nebkat!nebkat@unaffiliated/hacker ✘

    // Anything from an ip
    *!*@123.4.567.89:
            nebkat!nebkat@123.4.567.89 ✔
            123456!user2@123.4.567.89 ✔
            nebkat!nebkat@98.765.4.321 ✘

    // Anything where the username ends with nebkat
    *!*nebkat@*
            nebkat!nebkat@unaffiliated/nebkat ✔
            nebkat!prefix_nebkat@unaffiliated/nebkat ✔
            nebkat!nebkat_suffix@unaffiliated/nebkat ✘

Answer 1

结束了这个：

public static boolean match(String host, String mask) {
    String[] sections = mask.split("\\*");
    String text = host;
    for (String section : sections) {
        int index = text.indexOf(section);
        if (index == -1) {
            return false;
        }
        text = text.substring(index + section.length());
    }
    return true;
}

使用org.apache.commons.io.FilenameUtils #worldcardMatch（）方法。更多细节在回答https://stackoverflow.com/a/43394347/466677。
