自定义熔炉和合成表：

public class CustomRecipe {
    public static void register() {
        /**
         * 熔炉合成
         */
        NamespacedKey key1 = new NamespacedKey(MyPlugin.instance, "furnace_recipe");
        // 钻石
        ItemStack result1 = new ItemStack(Material.DIAMOND, 1);
        FurnaceRecipe furnaceRecipe = new FurnaceRecipe(key1, result1, Material.DIRT, 0f, 3 * 20);
        Bukkit.addRecipe(furnaceRecipe);

        /**
         * 自定义工作台合成
         * Shaped 定型
         * Shapeless 无定型
         * rows
         * ["  P","  S","   "]
         */
        NamespacedKey craftKey = new NamespacedKey(MyPlugin.instance, "craft_table");
        ShapedRecipe shapedRecipe = new ShapedRecipe(craftKey, result1);
        // 摆放合成表
        shapedRecipe.shape(
                "  P",
                "  S",
                "   ");
        // 设置合成表的原料
        shapedRecipe.setIngredient('P', Material.BLAZE_POWDER);
        shapedRecipe.setIngredient('S', Material.SLIME_BALL);
        Bukkit.addRecipe(shapedRecipe);
    }

 */
public class VillagerExecutor implements CommandExecutor {
    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if ("villager".equalsIgnoreCase(label)) {
            if (sender instanceof Player player) {
                World world = player.getWorld();
                Location location = player.getLocation();

                Villager villager = (Villager) world.spawnEntity(location, EntityType.VILLAGER);
                // 修改村民信息
                villager.setAI(false);
                villager.setCustomName("蔡徐坤的奸商村民");

                // 交易集合
                List<MerchantRecipe> recipes = new ArrayList<>();
                // 结果1
                ItemStack result1 = new ItemStack(Material.DIAMOND_BLOCK, 1);
                // 交易1
                MerchantRecipe recipe1 = new MerchantRecipe(result1, 3);
                // 交易所需物品
                List<ItemStack> materials1 = new ArrayList<>();
                materials1.add(new ItemStack(Material.DIRT, 3));
                recipe1.setIngredients(materials1);
                recipe1.setIngredients(materials1);
                recipes.add(recipe1);


                // 结果2
                ItemStack result2 = new ItemStack(Material.FEATHER, 2);
                MerchantRecipe recipe2 = new MerchantRecipe(result2, 1);
                List<ItemStack> materials2 = new ArrayList<>();
                materials2.add(new ItemStack(Material.DIRT, 1));
                materials2.add(new ItemStack(Material.DIAMOND_BLOCK, 2));
                recipe2.setIngredients(materials2);
                recipes.add(recipe2);

                // 设置交易
                villager.setRecipes(recipes);

                return true;
            }
        }
