EventWaiter 不起作用 - Java Discord API

Question

当有人使用下面的代码添加对特定消息的反应时，我正在尝试创建一个 EventWaiter，但它似乎不起作用。我已经尝试修复每一个可能是错误的事情， 然而什么也没发生。 控制台上没有显示错误，似乎 eventwaiter 没有监听 MessageReactionAdd 类

private static final String EMOTE = "\uD83D\uDE39";

// send a message to Dm and starts the method
event.replyInDm("message", (message - > {
  message.addReaction("\uD83D\uDD27").queue();
  initWaiter(message.getIdLong(), channel);
}));

private void initWaiter(long messageId, PrivateChannel channel) {
// waiting for a specific reaction (EMOTE) in a message with the same id as the message above
  waiter.waitForEvent(
    MessageReactionAddEvent.class,
    (e) - > {
      MessageReaction.ReactionEmote emote = e.getReactionEmote();
      assert user != null;
      return e.getMessageIdLong() == messageId && EMOTE.equals(emote.getName()) && !emote.isEmote() && !user.isBot();
    },
    (e) - > {
// if the code above is true, this should happen, but it doesn't
      assert channel != null;
      channel.sendMessage("message").queue();
    }
  );

确保将 EventWaiter 添加为 JDABuilder 中的侦听器：

JDABuilder.createDefault("token", intents)
          .addEventListeners(..., waiter)
          ...

如果您将服务员注册为侦听器，则可能缺少所需的 DIRECT_MESSAGE_REACTIONS 意图，假设您正在运行最新版本的 jda 之一
