Discord all-purpose bot, made using Spring Boot, JPA, Hibernate, REST, HikariCP, JDA.

TravisCI

Find the file app.properties in the resources folder and change following variables:

• prefix: The prefix for all command
• discordToken: Token from discord bot, https://discord.com/developers/applications

Every bot command should be a part of the com.motyldrogi.bot.command package and implement the CommandExecutor class, implementing the execute() method at bare-minimum. The execute() method expectes two arguments:

• dMessage (DiscordMessage): The DiscordMessage object which contains the full information about the message
• commandSender (CommandSender): The class for sending messages and also for localization

The execute() method needs a CommandInfo() annotation to work, the CommandInfo() annotation can have the following arguments:

• value: The value that triggers the command, i.e. after the prefix
• minArguments: Minimum arguments count for the command, defaults to 0
• maxArguments: Maximum arguments count for the command, defaults to 0
• usage: Text that gets displayed if the command was not used correctly

For example, the following command echos back the message received in an embeded message:

package com.motyldrogi.bot.command;

import com.motyldrogi.bot.command.defaults.CommandExecutor;
import com.motyldrogi.bot.command.defaults.CommandInfo;
import com.motyldrogi.bot.command.defaults.CommandSender;
import com.motyldrogi.bot.component.DiscordMessage;
import org.springframework.stereotype.Component;
import java.awt.Color;
import net.dv8tion.jda.api.EmbedBuilder;
import net.dv8tion.jda.api.entities.MessageEmbed;

@Component
public class EchoCommand implements CommandExecutor {

  @CommandInfo(value = "echo", minArguments = 1, maxArguments = 1, usage = "<message>")
  @Override
  public void execute(DiscordMessage dMessage, CommandSender commandSender) {

    MessageEmbed messageEmbed = new EmbedBuilder()
          .setColor(Color.decode("#ffffff"))
          .setTitle(dMessage.getSentBy() + " said..")
          .setDescription(dMessage.getData())
          .build();

    commandSender.sendEmbedMessage(messageEmbed);
  }
}

If you created a command, you have to register it:

this.commandRegistry.registerByExecutors(
    [...],
    new EchoCommand()
);
