如何检查字符串列表是否包含确切的字符串？

Question

我想做的是为我的服务器制作一个 Anti-swear 插件。它工作正常，但玩家可以轻松绕过它。假设在我的配置中列出了“测试”一词。如果玩家在聊天中正常输入“测试”一词，插件将检测到它。但是如果玩家输入，例如“testttttttt”，插件将不会检测到它。我怎样才能让它检测到这个词，只要它就在那里？这是我目前的代码：

public class EventsClass implements Listener {

        AntiSwear plugin = AntiSwear.getPlugin(AntiSwear.class);

        // Message when player joins the server
        @EventHandler
        public void onPlayerJoinEvent(PlayerJoinEvent event) {
            Player player = event.getPlayer();
            player.sendMessage(ChatColor.GOLD + "This server is running AntiSwear v1.0");

        // The punishment system
        }
        @EventHandler
        public void chatevent(AsyncPlayerChatEvent event) {
            for (String s : event.getMessage().split(" ")) {
                if (plugin.getConfig().getStringList("swears").contains(s)) {
                    event.setCancelled(true);
                    event.getPlayer().sendMessage(ChatColor.RED + "§lProfanity is not allowed on this server!");

                    // The punishment itself
                    Bukkit.getScheduler().runTask(plugin, () -> {

                        event.getPlayer().damage(10);
                        Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "smite " + event.getPlayer().getName());
                        Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "eco take " + event.getPlayer().getName() + " 100");
                        Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "burn " + event.getPlayer().getName() + " 5");
                        plugin.getServer().broadcastMessage(ChatColor.GOLD + "§lPlayer " + event.getPlayer().getName() + " §lused a swear word and has been punished!");
                    });
                }
            }
        }
    }

你试过这个吗？既然您希望命中任何匹配项，而不是拆分和检查列表中的 contains，为什么不对所有“发誓”单词的字符串执行 contains。所以基本上是从你正在做的事情中进行反向搜索。我假设您仅将 String 用于搜索而不用它做任何其他事情。

Answer 2

您需要遍历列表并为每个项目执行 contains 检查，而不是检查完全匹配的列表：

List<String> swears = plugin.getConfig().getStringList("swears")
  .stream()
  .map(swear -> swear.toLowerCase() )
  .collect(Collectors.toList());

for(String s : event.getMessage().split(" ")){
  if(swears.stream().anyMatch(swear -> s.toLowerCase().contains(swear)){
    event.setCancelled(true);
    //...
  }
}
