SpringBoot实战——微信点餐系统

1、初始化项目

　　引入模块

　　

    
        
            org.springframework.boot
            spring-boot-starter-data-jpa
        
        
            org.springframework.boot
            spring-boot-starter-web
        

        
            mysql
            mysql-connector-java
            runtime
        
        
            org.projectlombok
            lombok
            true
        
        
            org.springframework.boot
            spring-boot-starter-test
            test
        
    

2、application.properties

　（1）改成application.yml，yml可读性较强 编辑较为简单

　（2）添加数据库配置

　　

spring:
  datasource:
    url: http://localhost:3036/sell?useUnicode=true&&characterEncoding=utf-8
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: root
  jpa:
    show-sql: true
  freemarker:
    allow-request-override: false
    cache: false
    check-template-location: true
    charset: utf-8
    content-type: text/html
    suffix: .ftl
    template-loader-path: classpath:/templates/

3、创建数据库

CREATE TABLE `order_detail` (
  `detail_id` varchar(32) NOT NULL,
  `order_id` varchar(32) NOT NULL,
  `product_id` varchar(32) NOT NULL COMMENT '商品id',
  `product_name` varchar(32) NOT NULL COMMENT '商品名称',
  `product_price` decimal(8,2) NOT NULL COMMENT '商品价格',
  `prodiuct_quantity` int(11) NOT NULL COMMENT '商品数量',
  `product_icon` varchar(512) DEFAULT NULL COMMENT '商品小图',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '修改时间',
  PRIMARY KEY (`detail_id`),
  KEY `idx_order_id` (`order_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='订单详情表';

CREATE TABLE `order_master` (
  `order_id` varchar(32) NOT NULL,
  `buyer_name` varchar(32) NOT NULL COMMENT '买家名字',
  `buyer_phone` varchar(32) NOT NULL COMMENT '买家电话',
  `buyer_address` varchar(32) NOT NULL COMMENT '买家地址',
  `buyer_openid` varchar(64) NOT NULL COMMENT '买家微信openId',
  `buyer_amount` decimal(8,2) NOT NULL COMMENT '订单总额',
  `buyer_status` tinyint(3) NOT NULL DEFAULT '0' COMMENT '订单状态，默认0新下单',
  `pay_status` tinyint(3) NOT NULL DEFAULT '0' COMMENT '支付状态，默认0未支付',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '修改时间',
  PRIMARY KEY (`order_id`),
  KEY `idx_buyer_openid` (`buyer_openid`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='订单表';

CREATE TABLE `product_category` (
  `category_id` int(11) NOT NULL AUTO_INCREMENT,
  `category_name` varchar(64) NOT NULL COMMENT '类别名称',
  `category_type` int(11) NOT NULL COMMENT '类名编号',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '修改时间',
  PRIMARY KEY (`category_id`),
  UNIQUE KEY `uqe_category_type` (`category_type`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='类别表';

CREATE TABLE `product_info` (
  `product_id` varchar(32) NOT NULL,
  `product_name` varchar(64) NOT NULL COMMENT '产品名称',
  `product_price` decimal(8,2) NOT NULL COMMENT '价格',
  `product_stock` int(11) NOT NULL COMMENT '库存',
  `product_description` varchar(64) DEFAULT NULL COMMENT '描述',
  `product_icon` varchar(512) DEFAULT NULL COMMENT '图标',
  `product_type` int(11) NOT NULL COMMENT '产品类型',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  PRIMARY KEY (`product_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='产品表';
