  • Core framework: Spring Boot
  • Database layer: Spring Data JPA /Spring Data mongodb
  • Database connection pool: Druid
  • Cache: Ehcache
  • Front end: Vue. Js
  • Database: mysql5.5 +,Mongodb4.0(don’t use latest version 4.2)

The module

  • Flash-waimai-mobile mobile terminal site
  • Flash-waimai-manage Background management system
  • Flash-waimai-api Java interface service
  • Flash-waimai-core Underlying core module
  • Flash-waimai-generate code generation module

Quick start

  • Data stores use mysql and mongodb. Basic management configuration data is stored in mysql and service data is stored in mongodb.
  • Create mysql database
    CREATE DATABASE IF NOT EXISTS waimai DEFAULT CHARSET utf8 COLLATE utf8_general_ci; 
    CREATE USER 'waimai'@'%' IDENTIFIED BY 'waimai123';
    GRANT ALL privileges ON waimai.* TO 'waimai'@'%';
    flush privileges;
Copy the code
  • After the mysql database is created, the flash-Waimai-API service will automatically initialize the data, without the need for developers to manually initialize the data themselves
  • Install mongo and create database: flash – waimai use mongorestore command import mongo data, because of the large amount of test data, packaged in baidu cloud disk: link: pan.baidu.com/s/1mfO7yckF… Extract code: apGD after downloading, extract the file to D :\elm and import the data with the following command:
mongorestore.exe -d flash-waimai d:\\elm
Copy the code

  • Download the project the picture of the test data (merchants and food pictures) : link: pan.baidu.com/s/1rvZDspoa… Extract code: urzw, save the image in t_sys_cfg table system.file.upload.path in the specified directory

  • Start the management platform:

  • Enter the flash-Waimai-manage directory:

  • Run NPM install — registry.npm.taobao.org

  • Run NPM run dev

  • After the startup is successful, visit http://localhost:9528 and log in. The user name and password are admin and admin

  • Start the mobile phone:

  • Enter the Flash-Waimai-Mobile directory:
