Discord bot 无法使用 JDA 在 java 中发送消息

Question

我的 discord bot 做了所有 neccaserry 的事情，所以在纸上它应该可以工作，但它没有

运行控制台/终端时打印如下：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J:
See http://www.slf4j.org/codes.html#StaticLoggerBinder for further
details. SLF4J: Failed to load class "org.slf4j.impl.StaticMDCBinder".
SLF4J: Defaulting to no-operation MDCAdapter implementation. SLF4J:
See http://www.slf4j.org/codes.html#no_static_mdc_binder for further
details. [main] INFO JDA - Login Successful! [JDA MainWS-WriteThread]
INFO WebSocketClient - Connected to WebSocket [JDA MainWS-ReadThread]
INFO JDA - Finished Loading!

下面的类 Main.java：

import net.dv8tion.jda.api.JDABuilder;

public class Main {
    public static void main(String[] args) throws Exception{
        try {
            net.dv8tion.jda.api.JDA api = JDABuilder.createDefault("********************").build();
            api.addEventListener(new MyEventListener());
        } catch (Exception exc) {
            exc.printStackTrace();
        }
    }
}

下面的类 MyEventListener.java：

import net.dv8tion.jda.api.events.message.MessageReceivedEvent;
import net.dv8tion.jda.api.hooks.ListenerAdapter;
public class MyEventListener extends ListenerAdapter {
    public void onMessageReceived(MessageReceivedEvent event) {
        if (event.getAuthor().isBot()) return;
        
        Message message = event.getMessage();
        String content = message.getContentRaw();
        MessageChannel channel = event.getChannel();
        
        if (content.startsWith("?test")) {
            channel.sendMessage(":thinking:");
        }
    }

}

当我输入createDefault("********************").build(); 时 *********** 是机器人令牌，它是正确的

您没有在channel.sendMessage(":thinking:"); 上调用queue()，它返回MessageAction（RestAction<Message> 的实现。有关更多信息，请参阅下面的链接。
