欢迎听众不工作（Java Discord JDA）

Question

我试图让我的机器人在有人加入时欢迎某人，但我似乎无法让它工作。例如（顺便说一句，这将出现在嵌入中）：

@Jason joined. You must construct additional pylons.

有人可以帮我编辑我的代码使其正常工作吗？

这是我的主要代码：

import Events.*;
import net.dv8tion.jda.api.JDABuilder;
import net.dv8tion.jda.api.entities.Activity;

import javax.security.auth.login.LoginException;

public class Main {
    public static void main(String[] args) throws LoginException {
        JDABuilder jda = JDABuilder.createDefault("I imported key here");
        jda.setActivity(Activity.watching("baldness"));

        jda.addEventListeners(new Help());
        jda.addEventListeners(new PingPong());
        jda.addEventListeners(new Clear());
        jda.addEventListeners(new Welcome());

        jda.build();

    }
}

这是我的欢迎代码：

package Events;

import java.util.Random;

import net.dv8tion.jda.api.EmbedBuilder;
import net.dv8tion.jda.api.events.guild.member.GuildMemberJoinEvent;
import net.dv8tion.jda.api.hooks.ListenerAdapter;

public class Welcome extends ListenerAdapter {

    public class GuildMemberJoin extends ListenerAdapter {

        String[] messages = {
                "[member] joined. You must construct additional pylons.",
                "Never gonna give [member] up. Never let [member] down!",
                "Hey! Listen! [member] has joined!",
                "Ha! [member] has joined! You activated my trap card!",
                "We've been expecting you, [member].",
                "It's dangerous to go alone, take [member]!",
                "Swoooosh. [member] just landed.",
                "Brace yourselves. [member] just joined the server.",
                "A wild [member] appeared."
        };

        public void onGuildMemberJoin(GuildMemberJoinEvent event) {
            Random rand = new Random();
            int number = rand.nextInt(messages.length);

            EmbedBuilder join = new EmbedBuilder();
            join.setColor(0x66d8ff);
            join.setDescription(messages[number].replace("[member]", event.getMember().getAsMention()));

            event.getGuild().getDefaultChannel().sendMessage(join.build()).queue();
        }
    }
}

documentation fo GuildMemberJoinEvent 明确指出：

Requirements

This event requires the GUILD_MEMBERS intent to be enabled. createDefault(String) and createLight(String) disable this by default!

因此您必须启用意图。在 wiki 指南中阅读更多内容 Gateway Intents and Member Cache Policy

此外，您无缘无故地嵌套了 class，这意味着您将封闭的 class 注册为侦听器，而不是实际实现它的嵌套 class。

更好：

public class Welcome extends ListenerAdapter {
  @Override
  public void onGuildMemberJoin(GuildMemberJoinEvent event) {
    ...
  }
}
