使用监听器

@Override  
public InteractionResultHolder<ItemStack> use(Level level, Player player, InteractionHand hand) {  
    if(!level.isClientSide() && (hand == InteractionHand.MAIN_HAND || hand == InteractionHand.OFF_HAND)){  
        player.sendSystemMessage(Component.literal("测试"));  
        }  
    return super.use(level,player,hand);  
}

新建net.emtips.leespeaker.Customitem Configtool类

package net.emtips.leespeaker.CustomItem;  
  
import net.minecraft.network.chat.Component;  
import net.minecraft.world.InteractionHand;  
import net.minecraft.world.InteractionResultHolder;  
import net.minecraft.world.entity.player.Player;  
import net.minecraft.world.item.Item;  
import net.minecraft.world.item.ItemStack;  
import net.minecraft.world.level.Level;  
  
public class Configtool extends Item {  
  
    public Configtool(Properties properties) {  
        super(properties);  
    }  
  
    @Override  
    public InteractionResultHolder<ItemStack> use(Level level, Player player, InteractionHand hand) {  
        if(!level.isClientSide() && (hand == InteractionHand.MAIN_HAND || hand == InteractionHand.OFF_HAND)){  
            player.sendSystemMessage(Component.literal("测试"));  
            }  
        return super.use(level,player,hand);  
    }  
}
