一、商城 - 商城架构

1.1 工程结构分析与设计

十四、商城 - 商城架构-SSM(2)_第1张图片

工程说明:

  • youlexuan_parent 聚合工程
  • youlexuan_pojo 通用实体类层
  • youlexuan_dao 通用数据访问层
  • youlexuan_xxxxx_interface 某服务层接口
  • youlexuan_xxxxx_service 某服务层实现
  • youlexuan_xxxxx_web 某web工程

1.2 创建数据库表

创建 youlexuan 数据库而后执行 youlexuan_db.sql

1.3 搭建框架

1.3.1 父工程

  • 创建Maven工程 (POM) ,
  • groupId 为com.zql,
  • artifactId 为 youlexuan_parent ,

maven 的准备

3、创建spring配置文件

创建包 com.zql.sellergoods.service.impl

在src/main/resources下创建 spring/applicationContext_service.xml


<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <dubbo:protocol name="dubbo" port="20881">dubbo:protocol>
    <dubbo:application name="youlexuan_sellergoods_service"/>
    <dubbo:registry address="zookeeper://192.168.188.180:2181"/>
    <dubbo:annotation package="com.zql.sellergoods.service.impl" />
beans>

4、创建web.xml

在webapps下创建WEB-INF/web.xml ,加载spring容器

十四、商城 - 商城架构-SSM(2)_第11张图片


<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

    
    <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>classpath*:spring/applicationContext_*.xmlparam-value>
    context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>
web-app>

注意:加载spring配置文件必须增加classpath*:spring/applicationContext*.xml
要不然加载数据库驱动会保存。

1.3.7 运营商管理后台

2、创建 springmvc 配置文件

创建包 com.zql.sellergoods.controller

在src/main/resources下创建 spring/springmvc.xml


<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"

		http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    <context:component-scan base-package="com.zql.sellergoods.controller"/>

    <mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
            <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                <property name="supportedMediaTypes" value="application/json"/>
                <property name="features">
                    <array>

                        <value>WriteDateUseDateFormatvalue>
                    array>
                property>
            bean>
        mvc:message-converters>
    mvc:annotation-driven>
    
    <dubbo:application name="youlexuan_manager_web" />
    <dubbo:registry address="zookeeper://192.168.188.180:2181"/>
    <dubbo:annotation package="com.zql.sellergoods.controller" />
beans>

注意配置:fastjSON处理json

3、创建web.xml

1.3.8 商家管理后台

1、构建web模块 youlexuan_shop_web

十四、商城 - 商城架构-SSM(2)_第14张图片
与运营商管理后台的构建方式类似。

2、修改Pom.xml (注:要加 war)


<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            plugin>
        plugins>
    build>

project>

注意:定义tomcat的启动端口为9102

3、创建springmvc配置文件

在src/main下创建包:com.zql.shop.controller

在src/main/resources下创建 spring/springmvc.xml


<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

            bean>
        mvc:message-converters>
    mvc:annotation-driven>
    
    <dubbo:application name="youlexuan_shop_web" />
    <dubbo:registry address="zookeeper://192.168.188.180:2181"/>
    <dubbo:annotation package="com.zql.shop.controller" />
beans>

4、创建web.xml

在webapps下创建WEB-INF/web.xml ,加载spring容器

1.4 实体类与数据访问层模块

1.4.1 生成代码

利用反向工程 generatorSqlmapCustom 实现实体类与数据访问层代码的自动生成

(1) 导入IDEA 进行自己对应的配置

十四、商城 - 商城架构-SSM(2)_第16张图片

(2) 一键生成

十四、商城 - 商城架构-SSM(2)_第17张图片

1.4.2 拷贝代码

  • 将com.zql.pojo包拷贝到pojo工程
  • 将com.zql.mapper 包和 resouce 下的 com.zql.mapper 文件夹拷贝到 dao 工程(拷贝时确认连同包路径一起拷贝,可能出现包路径作为资源文件路径情况,出现错误绑定失败错误)

(3) 生成 优乐选 代码 点我

copy 如下位置

1.4.3 修改实体类代码

修改每个实体类,让其实现 Serializable 接口(次要,因为使用的都实现了Serializable 接口)

二、品牌列表-后端代码

2.1 需求分析

完成品牌管理的后端代码,在浏览器可查询品牌的数据(json格式)

5.2数据库表

tb_brand 品牌表

字段 类型 长度 含义
id Bigint 主键
name Varchar 255 品牌名称
first_char Varchar 1 品牌首字母

2.2 后端代码

2.2.1 服务层接口

在 youlexuan_sellergoods_interface 工程创建 BrandService 接口

包名 :com.zql.sellergoods.service

package com.zql.sellergoods.service;

import com.zql.pojo.TbBrand;

import java.util.List;

/**
 * 品牌服务层接口
 * @Author:Daniel
 * @Version 1.0
 */
public interface BrandService {

    /**
     * 返回全部列表
     * @return
     */
    public List<TbBrand> findAll();
}

2.2.2 服务实现类

在 youlexuan_sellergoods_service 工程创建 BrandServiceImpl 类

包名 com.zql.sellergoods.service.impl (应该搭建框架的时候创建了包名)

package com.zql.sellergoods.service.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.zql.mapper.TbBrandMapper;
import com.zql.pojo.TbBrand;
import com.zql.sellergoods.service.BrandService;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.List;

/**
 * @Author:Daniel
 * @Version 1.0
 */

@Service  //dubbo
public class BrandServiceImpl implements BrandService {
    
    @Autowired
    private TbBrandMapper brandMapper;
    @Override
    public List<TbBrand> findAll() {
        
        return brandMapper.selectByExample(null);
    }
}

2.2.3 控制层代码

在 youlexuan_manager_web 工程创建 com.zql.sellergoods.controller 包,包下创建BrandController类 (应该搭建框架的时候创建了包名)

package com.zql.sellergoods.controller;

import com.zql.pojo.TbBrand;
import com.zql.sellergoods.service.BrandService;
import jdk.nashorn.internal.ir.annotations.Reference;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

/**
 * 品牌controller
 * @Author:Daniel
 * @Version 1.0
 */
@RestController   //可点击看源码了解哈哈
@RequestMapping("/brand")
public class BrandController {

    @Reference  //dubbo
    private BrandService  brandService;
    @RequestMapping("/findAll")
    public List<TbBrand> findAll(){

        return brandService.findAll();
    }
}

2.3 测试

  1. 整体安装哈哈

十四、商城 - 商城架构-SSM(2)_第20张图片

  1. 启动 youlexuan_sellergoods_service

十四、商城 - 商城架构-SSM(2)_第21张图片

  1. 启动youlexuan_manager_web

十四、商城 - 商城架构-SSM(2)_第22张图片

(1) 地址栏输入 http://192.168.188.180:8080/dubbo 查看是否有服务提供者

在这里插入图片描述

(2) 地址栏输入 http://localhost:9101/brand/findAll.do

报错解决 十一、org.apache.ibatis.binding.BindingException…

十四、商城 - 商城架构-SSM(2)_第23张图片

(3)再次查看是否有消费者

2.4 快捷启动 tomcat

(1) 快捷启动 youlexuan_sellergoods_service

十四、商城 - 商城架构-SSM(2)_第25张图片

(2) 快捷启动 youlexuan_manager_web 同(1)

OK 项目架构起初成功,可以看到浏览器输出了 json 数据。 ✌✌
