错误 R10（启动超时）-> Web 进程未能在启动后 90 秒内绑定到 $PORT（Heroku 上的 Java Discord 机器人）

Question

我正在使用 gradle 和 spring boot 在 Java 中制作一个不和谐的机器人。当我在 IntelliJ IDEA 中启动应用程序时，它运行良好。它也适用于引发错误之前的前 90 秒。我添加了一个 Procfile，但它并没有解决问题。我看不出问题出在哪里。

代码

import discord4j.core.DiscordClient;
import discord4j.core.DiscordClientBuilder;
import discord4j.core.GatewayDiscordClient;
import discord4j.core.event.domain.message.MessageCreateEvent;
import discord4j.core.object.entity.Member;
import discord4j.core.object.entity.Message;
import discord4j.core.object.entity.User;
import discord4j.core.object.entity.channel.MessageChannel;
import reactor.core.publisher.Mono;

import java.util.Optional;

public class Main {
    public static void main(final String[] args){
        final GatewayDiscordClient client = DiscordClientBuilder.create("Token").build().login().block(); 
//"Token" is replaced by actual bot token in live code
        client.on(MessageCreateEvent.class).subscribe(event -> {
            final Message message = event.getMessage();
            if(message.getContent().contains("UwU")
                    || message.getContent().contains("uwu")
                    || message.getContent().contains("OwO")
                    || message.getContent().contains("owo")
                    || message.getContent().contains("UWU")
                    || message.getContent().contains("uWu")
                    || message.getContent().contains("uWU")
                    || message.getContent().contains("uwU")
                    || message.getContent().contains("UWU")
                    || message.getContent().contains("UWu")
                    || message.getContent().contains("oWo")
                    || message.getContent().contains("Owo")
                    || message.getContent().contains("owO")
                    || message.getContent().contains("OWo")
                    || message.getContent().contains("oWO")
                    || message.getContent().contains("0W0")
                    || message.getContent().contains("Onii-chan")
                    || message.getContent().contains("onii-chan")
                    || message.getContent().contains("Daijobu")
                    || message.getContent().contains("daijobu")
                    || message.getContent().contains("Nani")
                    || message.getContent().contains("nani")
                    || message.getContent().contains("Yare Yare")
                    || message.getContent().contains("yare yare")
                    || message.getContent().contains("tsundere")
                    || message.getContent().contains("Tsundere")
                    || message.getContent().contains("baka")
                    || message.getContent().contains("Baka")
                    || message.getContent().contains("Senpai")
                    || message.getContent().contains("senpai")
                    || message.getContent().contains("Yandere")
                    || message.getContent().contains("yandere")
                    || message.getContent().contains("Loli")
                    || message.getContent().contains("loli")
                    || message.getContent().contains("OWO")){
                message.delete().block();
                final MessageChannel channel = message.getChannel().block();
                channel.createMessage("NO WEEBS ALLOWED!").block();
            }
        });
        client.onDisconnect().block();
    }
}

错误

2021-01-19T13:28:53.204752+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 90 seconds of launch

过程文件

web: java $JAVA_OPTS -Dserver.port=$PORT -jar build/libs/*.jar 

Answer 1

Procfile 配置了一个 WebDyno，它将尝试绑定到 PORT，问题是 Discord 机器人不会尝试这样做，而是定义一个后台任务（工作者）

worker: java -jar build/libs/*.jar
