如果你是入门Javaweb，那么这个商城项目就将会是个不错的入门选择，总代码以及素材附在文章底下百度网盘中。

ps:如报错，需根据自己的背景路径位置自行调整！！！

首先我们来看一下效果图

productlist页面：

productadd页面：

productedit页面：

************************************************************************************************************

下面附上代码：

1 数据库准备
创建商品数据库表： product

DROP TABLE IF EXISTS product;
CREATE TABLE product (
product_id int(11) PRIMARY KEY AUTO_INCREMENT COMMENT '产品id',
product_name varchar(63) DEFAULT NULL COMMENT '产品名称',
product_type varchar(2) DEFAULT NULL COMMENT '产品类型: 1-通讯,2-视频,3-家电',
can_sale varchar(2) DEFAULT NULL COMMENT '是否上架销售: 0-否,1-是',
manufacturer varchar(50) DEFAULT NULL COMMENT '生产厂家'
);

2 项⽬创建及配置
2.1 添加项⽬依赖
在pom.xml⽂件，添加依赖，确保有以下内容的依赖
1、 spring framework 全套组件
2、 aspectjrt （AOP实现）
3、 mybatis
4、 mybatis-spring
5、 servlet-api
6、 jsp-api
7、 jstl
8、 mysql驱动

        where product_id=#{productId};
    </update>

    <select id="findProductById" parameterType="INTEGER" resultMap="productResult">
        select * from product
        where product_id=#{productId};
    </select>

    <select id="findAllProduct" resultMap="productResult">
        select * from product;
    </select>
</mapper>

3.4 创建服务接⼝
在包com.hbxy.ssm.product.service中，创建ProductService.java接⼝

package com.ws.ssm.product.service;

import com.ws.ssm.product.model.Product;

import java.util.List;

public interface ProductService {
    public void addProduct(Product product);

    public void deleteProduct(int productId);

    public void deleteProductAll();

    public void updateProduct(Product product);

    public Product findProductById(int productId);

    public List<Product> findAllProduct();

}

3.5 创建服务实现类
在包com.hbxy.ssm.product.service.impl中，创建ProductServiceImpl.java类

package com.ws.ssm.product.service.impl;

import com.ws.ssm.product.dao.ProductMapper;
import com.ws.ssm.product.model.Product;
import com.ws.ssm.product.service.ProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class ProductServiceImpl implements ProductService {

    @Autowired
    private ProductMapper mapper;

    @Override
    public void addProduct(Product product) {
        mapper.addProduct(product);
    }

    @Override
    public void deleteProduct(int productId) {
        mapper.deleteProduct(productId);
    }

    @Override
    public void updateProduct(Product product) {
        mapper.updateProduct(product);
    }

    @Override
    public Product findProductById(int productId) {
        return mapper.findProductById(productId);
    }

    @Override
    public List<Product> findAllProduct() {
        return mapper.findAllProduct();
    }

    @Override
    public void deleteProductAll(){ mapper.deleteProductAll(); }
}

3.6 创建控制器
在包com.hbxy.ssm.product.controller中，创建ProductController.java类

package com.ws.ssm.product.controller;

import com.ws.ssm.product.model.Product;
import com.ws.ssm.product.service.ProductService;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.List;

@Controller /*控制器类*/
public class ProductController {
    @Autowired  /*自动装配，将spring容器中的bean自动和Product类中bean组装到一起*/
    private ProductService productService;

    @GetMapping("/productlist") /*将 HTTP GET 请求映射到特定的处理程序方法*/
    public String productList(Model model){
        //调⽤服务接⼝,获得数据
        List<Product> list = productService.findAllProduct();
        //把数据放进model,传递给⻚⾯展现
        model.addAttribute("productlist",list);
        //跳转到展现⻚⾯
        return "/jsp/product/product_list";
    }

    @GetMapping("/toproductadd")
    public String toProductAdd(Model model){
        //跳转到添加⻚⾯
        return "/jsp/product/product_add";
    }

    @PostMapping("/productadd")
    public String productAdd(Product product, Model model){
        //调⽤服务接⼝,添加数据
        productService.addProduct(product);
        //重定向到列表url
        return "redirect:productlist";
    }

    @GetMapping("/toproductedit")
    public String toProductEdit(int productId,Model model) {
        //调⽤服务接⼝,通过id查询获得数据
        Product product = productService.findProductById(productId);
        //把数据放进model,传递给⻚⾯展现
        model.addAttribute("product", product);
        //跳转到修改⻚⾯
        return "/jsp/product/product_edit";
    }

    @PostMapping("/productedit")
    public String productEdit(Product product, Model model){
        //调⽤服务接⼝,更新数据
        productService.updateProduct(product);
        //重定向到列表url
        return "redirect:productlist";
    }

    @RequestMapping("/productdelete")
        public String productDelete(int productId){
        //调⽤服务接⼝,删除

        productService.deleteProduct(productId);
        //重定向到列表url
        return "redirect:productlist";
    }

    @RequestMapping("/productdeleteall")
    public String productDeleteAll(){
        productService.deleteProductAll();
        return "redirect:productlist";
    }

5 创建/修改配置⽂件
5.1 创建/修改MyBatis配置⽂件
在src/main/resources⽬录下，创建mybatis-config.xml⽂件。如果mybatisconfig.xml已存在，则添加
相关模块的mapper.xml⽂件及声明别名

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!--定义别名，可以在mapper.xml使用-->
<typeAliases>
<typeAlias type="com.ws.ssm.product.model.Product" alias="product">
</typeAlias>
<!--定义mapper.xml在哪-->
</typeAliases>
<mappers>
<mapper resource="com/ws/ssm/product/mapper/ProductMapper.xml"/>
</mappers>
</configuration>

5.2 创建/修改Spring配置⽂件
在src/main/resources⽬录下，创建spring-config.xml⽂件。如果springconfig.xml已存在，则修改添
加mybatis相关内容，添加新的服务实现类的扫描路径

<?xml version="1.0" encoding="UTF-8"?>

                             characterEncoding=utf8&amp;
                             useUnicode=true"/>
        <property name="username" value="root"/>
        <property name="password" value="2205525477"/>
    </bean>

    <!--创建mybatis会话工厂-->
    <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

    <!--扫码mapper接口类-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.ws.**.dao"/>
    </bean>

    <!--扫描service服务接口-->
    <context:component-scan base-package="com.ws.**.service.impl"/>
</beans>

5.3 创建SpringMVC配置⽂件
在src/main/resources⽬录下，创建springmvc-config.xml⽂件。如果springmvc-config.xml已存在，
则修改添加新模块的控制器扫描路径

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
https://www.springframework.org/schema/mvc/spring-mvc.xsd">
<context:component-scan base-package="com.**.controller"/>
<bean id="viewerResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value=""/>
<property name="suffix" value=".jsp"/>
</bean>
<mvc:resources location="/static/" mapping="/static/**/*.*"/>
<!--注解驱动-->
<mvc:annotation-driven/>
</beans>

5.4 修改web.xml⽂件
修改web.xml⽂件，添加spring， springmvc的配置，以及处理中⽂的过滤器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<!--初始化spring容器-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-config.xml</param-value>
</context-param>
<listener>
<listenerclass>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<!--第⼀一个启动Spring容器器及其拦截器器-->
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
<!--所有的请求都需要经过DispatcherServlet转发处理理-->
</servlet-mapping>
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filterclass>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>

6、功能测试
