技术栈

• 前端： Thymeleaf,Bootstra,Jqueryy
• 后端： SpringBoot , MybatisPlus，Lombok
• 中间件: RabbitMq,Redis

项目搭建

主要就是简单整合一下mybatisPlus ，能连接数据库就行

• 配置

### port
server:
  port: 8080

spring:
## DB
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    url: jdbc:mysql://127.0.0.1:3306/demo?useUnicode=true&characterEncoding=utf-8
    username: root
    password: root
    druid:
      # 初始化大小，最小，最大
      initial-size: 5
      min-idle: 5
      max-active: 20
      # 配置获取连接等待超时的时间
      max-wait: 60000
      # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位毫秒
      time-between-eviction-runs-millis: 60000
      # 配置一个连接在池中最小生存时间
      min-evictable-idle-time-millis: 300000
## thymeleaf 关闭缓存
  thymeleaf:
    cache: false

## mybatisPlus
mybatis-plus:
  mapper-locations: classpath:/mapper/*Mapper.xml
  type-aliases-package: com.example.miaosha.pojo

## 日志
logging:
  level:
    com.example.miaosha.mapper: debug
