Use Webman to build a personalized online shopping platform
Introduction:
With the development of the Internet, more and more people choose online shopping to satisfy their needs shopping needs. In order to meet the personalized needs of users, it has become particularly important to establish a personalized online shopping platform. This article will introduce how to use the Webman framework to build a personalized online shopping platform, and provide some code examples for reference.
1. What is Webman?
Webman is a lightweight Web framework developed based on Java language. It provides a simple and efficient development method and is suitable for building various types of Web applications. Due to its simplicity and ease of use, Webman has become one of the preferred frameworks for many developers.

1. Environment setup
First, make sure that JDK and Maven are installed on your computer. Then, use Maven to create a new project:
mvn archetype:generate -DgroupId=com.example -DartifactId=shopping-platform -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
Next, enter the project folder and open the pom.xml file, and add Webman dependencies in the
<dependency> <groupId>com.webman</groupId> <artifactId>webman-core</artifactId> <version>1.0.0</version> </dependency>
Save the file and execute the following command to build the project:
mvn clean package
2. Create a database
Use a relational database to store product information and user order information. Create a database named "shopping_platform" in the MySQL database, and then create two tables: the product table and the order table.
The structure of the product table is as follows:
CREATE TABLE `product` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(100) NOT NULL, `price` decimal(10,2) NOT NULL, `description` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
The structure of the order table is as follows:
CREATE TABLE `order` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` int(11) NOT NULL, `product_id` int(11) NOT NULL, `quantity` int(11) NOT NULL, `create_time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
3. Write code
First, create a file named " Product" Java class, used to encapsulate product information:
public class Product { private int id; private String name; private double price; private String description; // 省略getter和setter方法 }
Then, create a Java class named "Order", used to encapsulate order information:
public class Order { private int id; private int userId; private int productId; private int quantity; private Date createTime; // 省略getter和setter方法 }
Next, create a A Java class named "ProductDao" is used to operate product data:
public class ProductDao { public List<Product> findAll() { // 查询所有商品信息的代码 } // 省略其他操作方法 }
Create a Java class named "OrderDao" to operate order data:
public class OrderDao { public void save(Order order) { // 保存订单信息的代码 } // 省略其他操作方法 }
Finally, create a A Java class named "ShoppingController" is used to handle front-end requests:
public class ShoppingController { private ProductDao productDao = new ProductDao(); private OrderDao orderDao = new OrderDao(); public void showProductList() { List<Product> productList = productDao.findAll(); // 返回商品列表数据给前端页面的代码 } public void placeOrder(int userId, int productId, int quantity) { Order order = new Order(); order.setUserId(userId); order.setProductId(productId); order.setQuantity(quantity); order.setCreateTime(new Date()); orderDao.save(order); // 返回下单成功的提示信息给前端页面的代码 } // 省略其他处理请求的方法 }
IV. Summary
Compared with traditional development methods, using the Webman framework to build a personalized online shopping platform can improve development efficiency and user experience. Through the above sample code, we can see that Webman is easy to use and flexible, allowing developers to focus more on the implementation of business logic and quickly build a personalized online shopping platform.
