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: truefreemarker:

allow-request-override: falsecache:falsecheck-template-location: truecharset: utf-8content-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‘,

) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT=‘订单详情表‘;CREATE TABLE`order_master` (
