SpingBoot的项目实战--模拟电商【1.首页搭建】

1.项目背景

写此项目的初衷：最近后台接到了蛮多私信，很多的都在问springboot搭建一个项目会使用到哪些技术，以及怎么写这样一个项目。为了将技术更好的运用以及讲解，于是小编利用工作的空闲时间，写了一个可以训练自己技术点的小项目，大家有兴趣的可以订阅这个合集。

提要：因为这个项目只是练手，数据量很少，也就不存在什么请求卡顿之类的问题了，我就没有在sql优化中花费太多心思了

2.技术点运用

FreeMarker，SpringBoot，Mybatis-plus，Auto2，Spring Security，Mysql，Redis

二.数据库表及依赖

1.数据库

数据库脚本也已经上传上去了，在这篇博文可以看见

2.依赖

三.需求

1.页面分析

这个已经转成pdf文件上传在这篇博文中了

2.数据更换（静态?动态）

（1）分类数据

（2）具体类别商品展示

①装饰摆件

②墙式壁挂

四.代码编写

0.需求

需要将数据库中对应的商品信息展示在首页

1.代码生成（model，mapper，service）

代码生成类

    private final static String URL = "jdbc:mysql://localhost:3306/easyshop";
    private final static String USERNAME = "root";
    private final static String PASSWORD = "123456";

    private final static DataSourceConfig.Builder DATA_SOURCE_CONFIG =
            new DataSourceConfig.Builder(URL, USERNAME, PASSWORD);

    public static void main(String[] args) {
        FastAutoGenerator.create(DATA_SOURCE_CONFIG)
                .globalConfig(
                        (scanner, builder) ->

                                .service("service")
                                .serviceImpl("service.impl")
                                .mapper("mapper")
                                .xml("mapper.xml")

                        builder.beforeOutputFile(
                                (a, b) -> log.warn("tableInfo: " + a.getEntityName())
                        )
                )
                .strategyConfig((scanner, builder) ->
                        builder.addInclude(getTables(scanner.apply("请输入表名,多个英文逗号分隔?所有输入 all")))
                                .addTablePrefix("tb_", "t_", "lay_", "meeting_", "sys_")
                                .entityBuilder()

                .templateEngine(new FreemarkerTemplateEngine())
                .execute();
    }

    protected static List<String> getTables(String tables) {
        return "all".equals(tables) ? Collections.emptyList() : Arrays.asList(tables.split(","));
    }

}

五.分类数据

这个地方因为自己在设计表的时候没有考虑完善，所以这个地方的遍历会有点复杂，我把哪些有二级目录的分类菜单的数据加到了数据库中

但是在其中有一些分类的类别是没有二级菜单的，所以这里需要查询三次

一次是查询有二级菜单的分类菜单

一次是查询没有二级菜单的分类菜单

一次是查询二级菜单的具体数据

1.mapper

package com.wh.easyshop.mapper;

import com.wh.easyshop.model.Goods;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;

import java.util.List;
import java.util.Map;

/**

 */
@Repository
public interface GoodsMapper extends BaseMapper<Goods> {
   

       /**
     * 首页分类
     * @param type
     * @return
     */
       List<Map<String,Object>> typelist (String type);


}

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

	</select>
</mapper>

2.service

package com.wh.easyshop.service;

import com.wh.easyshop.model.Goods;
import com.baomidou.mybatisplus.extension.service.IService;
import org.apache.ibatis.annotations.Param;

import java.util.List;
import java.util.Map;

/**

 */
public interface IGoodsService extends IService<Goods> {


    /**
     * 首页分类
     * @param type
     * @return
     */
    List<Map<String,Object>> typelist (String type);
}

package com.wh.easyshop.service.impl;

import com.wh.easyshop.model.Goods;
import com.wh.easyshop.mapper.GoodsMapper;
import com.wh.easyshop.service.IGoodsService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.apache.ibatis.annotations.Param;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
import java.util.Map;

/**
 * <p>
 * 商品信息表 服务实现类
 * </p>
 *
 * @author wh
 * @since 2023-12-27
 */
@Service
public class GoodsServiceImpl extends ServiceImpl<GoodsMapper, Goods> implements IGoodsService {
@Autowired
private  GoodsMapper goodsMapper;

   

    /**
     * 分类商品
     * @param type
     * @return
     */
    @Override
    public List<Map<String, Object>> typelist(String type) {
        return goodsMapper.typelist(type);
    }


}

            </li>

        </ul>
    </div>
</div>

六.类型具体数据

?1.mapper

????????因为我们展示的商品是按照类别来的，所以我们需要进行条件查询，所以这里我们自己编写一个接口就好了。

????????在下面的代码中有一个@Param注解，我们也可以看一下这个注解的作用到底是什么👇👇

@Param注解可用于给Mapper接口中的方法参数起别名。如果一个方法有多个参数，而且这些参数在SQL语句中使用了，则必须给每个参数加上该注解，以便在SQL语句中可以使用参数别名来引用参数

package com.wh.easyshop.mapper;

import com.wh.easyshop.model.Goods;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * <p>
 * 商品信息表 Mapper 接口
 * </p>
 *
 * @author wh
 * @since 2023-12-27
 */
@Repository
public interface GoodsMapper extends BaseMapper<Goods> {

    /**
     * 首页商品展示
     * @param type
     * @param size
     * @return
     */
    List<Goods> showGoods (@Param("type") String type, @Param("size") int size);

}

对了，我们这里因为是自己编写接口的，所以那个mapper.xml也是需要我们自己写的，目前我们在前端只需要展示装饰摆件以及墙式壁挂，但可能以后也会想要换成其他类型，所以我在mapper.xml中并没有把类型以及展示的条数写死，这样我们想要修改的时候，可以直接在controller层中进行修改

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.wh.easyshop.mapper.GoodsMapper">

    <select id="showGoods" resultType="com.wh.easyshop.model.Goods">
        SELECT
	    *
    FROM
	    t_goods g,
	    t_dict_data dd
    WHERE
	    dd.dict_value = #{type}
	AND
	    g.goods_type = dd.dict_value
	    limit #{size}
    </select>
</mapper>

2.service

package com.wh.easyshop.service;

import com.wh.easyshop.model.Goods;
import com.baomidou.mybatisplus.extension.service.IService;
import org.apache.ibatis.annotations.Param;

import java.util.List;

/**
 * <p>
 * 商品信息表 服务类
 * </p>
 *
 * @author wh
 * @since 2023-12-27
 */
public interface IGoodsService extends IService<Goods> {
    /**
     * 首页商品展示
     * @param type
     * @param size
     * @return
     */
    List<Goods> showGoods (@Param("type") String type, @Param("size") int size);

}

package com.wh.easyshop.service.impl;

import com.wh.easyshop.model.Goods;
import com.wh.easyshop.mapper.GoodsMapper;
import com.wh.easyshop.service.IGoodsService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * <p>
 * 商品信息表 服务实现类
 * </p>
 *
 * @author wh
 * @since 2023-12-27
 */
@Service
public class GoodsServiceImpl extends ServiceImpl<GoodsMapper, Goods> implements IGoodsService {
@Autowired
private  GoodsMapper goodsMapper;
    /**
     * 首页商品展示
     * @param type
     * @param size
     * @return
     */
    @Override
    public List<Goods> showGoods(String type, int size) {
        return goodsMapper.showGoods(type,size);
    }
}

3.controller

package com.wh.easyshop.controller;

import com.google.common.collect.Lists;
import com.wh.easyshop.model.Goods;
import com.wh.easyshop.service.IGoodsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

/**
 * <p>
 * 商品信息表 前端控制器
 * </p>
 *
 * @author wh
 * @since 2023-12-27
 */
@Controller

public class GoodsController {
    @Autowired
    private IGoodsService goodsService;

    /**
     * 首页商品展示
     * @param model
     * @return
     */
    @RequestMapping("/")
    public String index(Model model) {
        //商品集合
        List<Goods> g1 = goodsService.showGoods("01", 6);
        //切片
        List<List<Goods>> p1 = Lists.partition(g1, 3);
        //商品集合
        List<Goods> g2 = goodsService.showGoods("07", 12);
        //切片
        List<List<Goods>> p2 = Lists.partition(g2, 4);
        model.addAttribute("p1", p1);
        model.addAttribute("p2", p2);
        return "index";
    }
}

4.局部修改

这时候我们在前端遍历一下，我们的集合，现在就是需要把这个里面的东西都换成数据库来的值

这段是遍历的摆件花艺的值，但是我发现这样子遍历之后，前端的样式不对了

<div class="flower clearfix tran">
			<#list g1 as g>
			<a href="proDetail.html" class="clearfix">
				<dl>
					<dt>
						<span class="abl"></span>
						<img src="${g.goodsImg}"/>
						<span class="abr"></span>
					</dt>
					<dd>${g.goodsTitle}</dd>
					<dd><span>￥ 79.00</span></dd>
				</dl>
			</a>
		</#list>
		</div>

现在这些都是一排展示了，而原本它应该是有两排，每排三个的

也是因为我在遍历的时候是遍历的我拿到的6个元素，所以他就一次遍历出来了，如果我们需要完成那种两排的效果，那么需要做一个处理，让它一次只有三个出来，这里其实我们很容易就能够想到，可以使用切片来完成，使用切片也有许多的方法，这里小编使用的是guava，使用这个之前，需要引入相应的依赖

  <!--guava 切片-->
        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>31.0.1-jre</version>
        </dependency>

然后我们再修改一下controller层的方法以及前端页面

package com.wh.easyshop.controller;

import com.google.common.collect.Lists;
import com.wh.easyshop.model.Goods;
import com.wh.easyshop.service.IGoodsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

/**
 * <p>
 * 商品信息表 前端控制器
 * </p>
 *
 * @author wh
 * @since 2023-12-27
 */
@Controller

public class GoodsController {
    @Autowired
    private IGoodsService goodsService;
    @RequestMapping("/")
    public String index(Model model) {
        //商品集合
        List<Goods> g1 = goodsService.showGoods("01", 6);
        //切片
        List<List<Goods>> p1 = Lists.partition(g1, 3);
        //商品集合
        List<Goods> g2 = goodsService.showGoods("07", 12);
        //切片
        List<List<Goods>> p2 = Lists.partition(g2, 4);
        model.addAttribute("p1", p1);
        model.addAttribute("p2", p2);
        return "index";
    }
}

摆件花艺

<#list p1 as p>
		<div class="flower clearfix tran">
			<#list p as g>
			<a href="proDetail.html" class="clearfix">
				<dl>
					<dt>
						<span class="abl"></span>
						<img src="${g.goodsImg}"/>
						<span class="abr"></span>
					</dt>
					<dd>${g.goodsTitle}</dd>
					<dd><span>￥ 79.00</span></dd>
				</dl>
			</a>
		</#list>
		</div>
		</#list>

现在我们再看一下前端的页面展示，就可以发现是两排的啦

墙式壁挂

<div class="people">
	<div class="wrapper">
		<h2><img src="img/ih3.jpg"/></h2>
		<#list p2 as p>
		<div class="pList clearfix tran">
				<#list p as g>
			<a href="proDetail.html">
					<dl>
						<dt>
							<span class="abl"></span>
							<img src="${g.goodsImg}"/>
							<span class="abr"></span>
						</dt>
						<dd>${g.goodsTitle}</dd>
						<dd><span>￥${g.goodsPrice}</span></dd>
					</dl>
				</a>
			</#list>
		</div>
	</#list>
		</div>

5.html页面
