+请帮我将以下表转换为Java POJO对象，不需要getter和setter
+
+CREATE TABLE `goods_order_details`  (
+  `order_detail_id` int(11) NOT NULL AUTO_INCREMENT COMMENT '订单详情ID',
+  `order_id` int(11) NOT NULL COMMENT '订单ID',
+  `product_id` int(11) NOT NULL COMMENT '商品ID',
+  `product_quantity` int(11) NOT NULL COMMENT '商品数量',
+  PRIMARY KEY (`order_detail_id`) USING BTREE
+) ENGINE = InnoDB CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci ROW_FORMAT = Dynamic;
+
+CREATE TABLE `orders`  (
+  `order_id` int(11) NOT NULL AUTO_INCREMENT COMMENT '订单ID',
+  `user_id` int(11) NOT NULL COMMENT '用户ID',
+  `order_date` date NOT NULL COMMENT '订单日期',
+  `order_status` enum('Pending','Processing','Shipped','Delivered','Cancelled') CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL COMMENT '订单状态',
+  PRIMARY KEY (`order_id`) USING BTREE
+) ENGINE = InnoDB CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci ROW_FORMAT = Dynamic;

+例如：Good的对象为
+@Data
+public class Good {
+    Long id;
+    String goodsName;
+    Integer categoryId;
+    String brand;
+    String gallery;
+    String brief;
+    Boolean isOnSale;
+    String picUrl;
+    Integer type;
+    String unit;
+    Double counterPrice;
+    Double retailPrice;
+    String detail;
+    Boolean deleted;
