基于微信小程序的在线商城点单系统

前言：闲来无事，制作一个微信小程序商城。系统采用Java语言作为后端实现与小程序的交互，给用来学习或者想自己开个小店的朋友当个参考。

前言

项目功能及技术

小程序主要有首页、商品详情、商品分类、商品评价、购物车、个人中心等模块。
管理端主要有人员管理、权限管理、商品管理、订单管理等模块。

html+css+js：微信小程序界面。
SpringBoot框架+Java程序语言：小程序及后台管理系统API的实现。
Layui前端框架：web后台管理界面样式及数据渲染框架。
MySQL数据库：数据支持。

效果图

小程序

管理端

API

SpringBoot框架搭建

1.创建maven project，先创建一个名为SpringBootDemo的项目，选择【New Project】

然后在弹出的下图窗口中，选择左侧菜单的【New Project】

在project下创建module，点击右键选择【new】—【Module…】

左侧选择【Spring initializr】，通过idea中集成的Spring initializr工具进行spring boot项目的快速创建。窗口右侧：name可根据自己喜好设置，group和artifact和上面一样的规则，其他选项保持默认值即可，【next】

Developer Tools模块勾选【Spring Boot DevTools】，web模块勾选【Spring Web】，此时，一个Springboot项目已经搭建完成，可开发后续功能

实体映射创建Mapper

创建一个entity实体类文件夹，并在该文件夹下创建项目用到的实体类

package com.example.demo.entity;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import lombok.Data;

import java.time.LocalDateTime;
import java.util.ArrayList;
import java.util.List;

@Data
public class User {
    @TableId(type = IdType.AUTO)
    private Long id;

    private String account;

    private String pwd;

    private String userDesc;

    private String userHead;

    private LocalDateTime createTime;

    private Long role;

    private String nickname;

    private String email;

    private String tags;
}

接口封装

由于我们使用mybatis-plus，所以简单的增删改查不用自己写，框架自带了，只需要实现或者继承他的Mapper、Service

创建控制器Controller

整合Swagger

添加依赖

先导入spring boot的web包

    io.springfox
    springfox-swagger2
    2.9.2


    io.springfox
    springfox-swagger-ui
    2.9.2

配置Swagger

创建一个swagger的配置类，命名为SwaggerConfig.java

/*
     *用于定义API主界面的信息，比如可以声明所有的API的总标题、描述、版本
     */
    private ApiInfo apiDemo() {
        return new ApiInfoBuilder()
                //用来自定义API的标题
                .title("SpringBoot项目SwaggerAPIAPI标题测试")
                //用来描述整体的API
                .description("SpringBoot项目SwaggerAPI描述测试")
                //创建人信息
                .contact(new Contact("测试员张三","http://localhost:8080/springboot/swagger-ui.html","xxxxxxxx@163.com"))
                //用于定义服务的域名
                //.termsOfServiceUrl("")
                .version("1.0") //可以用来定义版本
                .build();
    }

接口测试

运行Spring Boot项目，默认端口8080，通过地址栏访问url

接口组定义

根据不同的业务区分不同的接口组，使用@API来划分

@Api(tags = "用户管理") //  tags：组名称
@RestController
public class RoleController {
}

接口定义

使用@ApiModel来标注实体类，同时在接口中定义入参为实体类作为参数。

• @ApiModel：用来标类

• 常用配置项：value：实体类简称；description：实体类说明

• @ApiModelProperty：用来描述类的字段的含义。

常用字段类型
