Discord4J 3.x 版本 Discord Bot 消息内添加按钮教程

Discord4J 3.x 版本提供了一种新的方式来添加消息内的按钮，使用ButtonInteractionListener接口来监听按钮事件。以下是添加按钮的步骤：

导入 Discord4J 和 Javacord 库

<dependency>
    <groupId>com.discord4j</groupId>
    <artifactId>discord4j-core</artifactId>
    <version>3.1.1</version>
</dependency>

<dependency>
    <groupId>org.javacord</groupId>
    <artifactId>javacord</artifactId>
    <version>3.3.2</version>
</dependency>

创建一个ButtonInteractionListener实现类来处理按钮点击事件

public class MyButtonListener implements ButtonInteractionListener {

    @Override
    public void onButtonInteraction(ButtonInteractionEvent event) {
        // 处理按钮点击事件
    }
}

创建一个Button对象并将其添加到消息中

// 创建一个按钮
Button button = Button.primary('myButton', 'Click me!');

// 创建一个消息，并将按钮添加到消息中
MessageCreateSpec spec = MessageCreateSpec.create(channelId).setContent('Hello, world!').addComponents(button);

// 注册按钮点击事件监听器
client.getEventDispatcher().on(ButtonInteractionEvent.class).subscribe(new MyButtonListener());
