Java簡單通配符匹配

Question

我正在製作java IRC庫，我需要一種方法來查看某個用戶是否與可包含通配符字符的主機掩碼相匹配。不使用正則表達式的最簡單方法是什麼？

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

結束了與此：

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＃wildcardMatch（）方法。更多的細節在回答https://stackoverflow.com/a/43394347/466677。
