Question

情况和问题：

我想在他们输入脏话时（不区分大小写）踢球员。以下是我的尝试，但它不会踢球员。我做错了什么？根本不显示任何错误。

源代码：

@EventHandler
public void onPlayerChat(AsyncPlayerChatEvent e) {

    Player player = e.getPlayer();

    if (muted.contains(player.getUniqueId())) {

        e.setCancelled(true);
        player.sendMessage(ChatColor.DARK_BLUE + "[TC]" + ChatColor.DARK_RED + "You are muted and cannot chat.");

    } else {

        String message = e.getMessage();

        if (message.contains("(?i)fuck") || message.contains("(?i)shit") || message.contains("(?i)ass") || message.contains("(?i)porno") || message.contains("(?i)porn") || message.contains("(?i)crap") || message.contains("(?i)dumb")) {

            player.kickPlayer(ChatColor.DARK_RED + "Watch your language, please!");
            e.setCancelled(true);

        }

        message = ChatColor.translateAlternateColorCodes('§', message);
        message = ChatColor.translateAlternateColorCodes('&', message);
        String text = ChatColor.DARK_BLUE + "[Chat]" + ChatColor.YELLOW + player.getName() + " " + ChatColor.DARK_RED + "Says: " + ChatColor.AQUA + message;
        player.playNote(player.getLocation(),Instrument.PIANO, Note.natural(1, Tone.A));

        text.replace("(?i)", "");

        text = text.replace("<3", "❤");
        text = text.replace(":)", "☺");
        text = text.replace(":-)", "☺");
        text = text.replaceAll("(?i)fuck", "****");
        text = text.replaceAll("(?i)ass", "***");
        text = text.replaceAll("(?i)shit", "****");
        text = text.replaceAll("(?i)porno", "*****");
        text = text.replaceAll("(?i)porn", "****");
        text = text.replaceAll("(?i)dumb", "****");
        text = text.replaceAll("(?i)crap", "****");

        e.setFormat(text);
        e.setMessage(text);

    }

}

使用String.matches匹配正则表达式。此外，您可以将所有发誓的单词添加到某个数组/集合中，并使用Java 8功能来简化代码，例如。

  public static void main(String[] args) {
    String message = "hello fuck world ass shit here i am";
    final String[] swearWords = {"ass", "fuck", "shit", "porno", "porn"};
    final boolean hasSwearWords = Stream.of(swearWords).anyMatch(w -> message.matches("(?i).*\\s" + w + "\\s.*"));
    if (hasSwearWords) {
      System.out.printf("Bad user!");
    }
    final String cleanMessage = Stream.of(swearWords).reduce(message,
        (msg, w) -> msg.replaceAll(
            "(?i)(\\s)" + w + "(\\s)",
            "$1" + new String(new char[w.length()]).replace("\0", "*")+ "$2"));
    System.out.println(cleanMessage);
  }

以下是不需要Java 8的代码：

  @EventHandler
  public void onPlayerChat(AsyncPlayerChatEvent e) {
    Player player = e.getPlayer();

    if (muted.contains(player.getUniqueId())) {
      e.setCancelled(true);
      player.sendMessage(ChatColor.DARK_BLUE + "[TC]" + ChatColor.DARK_RED + "You are muted and cannot chat.");
    } else {
      String message = e.getMessage();
      String[] swearWords = {"fuck", "shit", "ass", "porno", "porn", "crap", "dumb"};

      for (String word : swearWords) {
        if (message.matches("(?i).*\\s" + word + "\\s.*")) {
          player.kickPlayer(ChatColor.DARK_RED + "Watch your language, please!");
          e.setCancelled(true);
          break;
        }
      }

      message = ChatColor.translateAlternateColorCodes('§', message);
      message = ChatColor.translateAlternateColorCodes('&', message);
      String text =
          ChatColor.DARK_BLUE + "[Chat]" + ChatColor.YELLOW + player.getName() + " " + ChatColor.DARK_RED + "Says: " +
              ChatColor.AQUA + message;
      player.playNote(player.getLocation(), Instrument.PIANO, Note.natural(1, Tone.A));

      text = text.replace("<3", "❤")
                 .replace(":)", "☺")
                 .replace(":-)", "☺");
      for (String word : swearWords) {
        text = text.replaceAll(
            "(?i)(\\s)" + word + "(\\s)",
            "$1" + new String(new char[word.length()]).replace("\0", "*")+ "$2");
      }

      e.setFormat(text);
      e.setMessage(text);
    }
  }
