简化操作，路由约定自动加载，约定优于定义

console.log(require(egg.js))
 { startCluster: [Function],
  start: [AsyncFunction],
  Application: [Function: Application],
  Agent: [Function: Agent],
  AppWorkerLoader: [Function: AppWorkerLoader],
  AgentWorkerLoader: [Function: AgentWorkerLoader],
  Controller: [Function: BaseContextClass],
  Service: [Function: BaseContextClass],
  Subscription: [Function: BaseContextClass],
  BaseContextClass: [Function: BaseContextClass],
  Boot: [Function: BaseHookClass] }

controller

'use strict';

const Controller = require('egg').Controller;

class UserController extends Controller {
  async index() {
    const { ctx } = this;
    // ctx.body = 'go';
	ctx.body= await ctx.service.user.getall()
  }
}

module.exports = UserController;

service

'use strict';

const Service = require('egg').Service;

class UserService extends Service {
  async getall() {
	  return await this.ctx.model.User.findAll()
		// return [
		// 	{name:"zhangsan"},
		// 	{name:"lisi"}
		// ]
  }
}

module.exports = UserService;

model

module.exports = app => {
const { STRING } = app.Sequelize;
const User = app.model.define(
	"user",
	{ name: STRING(30) },
	{ timestamps: false }
	);
	// 数据库同步
	// User.sync({force: true})
	return User;
};

router.js

'use strict';

/**
 * @param {Egg.Application} app - egg application
 */
module.exports = app => {
  const { router, controller } = app;
  router.get('/', controller.home.index);
  router.get('/user', controller.user.index);
};

model service controller层的文件名字不能乱改，因为是约定的，不需要额外配置，只有router.js里要手动添加一下接口路由，而且也不需要引入的

config.default.js

/* eslint valid-jsdoc: "off" */

'use strict';

/**
 * @param {Egg.EggAppInfo} appInfo app info
 */
module.exports = appInfo => {
  /**
   * built-in config
   * @type {Egg.EggAppConfig}
   **/
  const config = exports = {};

  // use for cookie sign key, should change to your own and keep security
  config.keys = appInfo.name + '_1586241771946_3772';

  // add your middleware config here
  config.middleware = [];

  // add your user config here
  const userConfig = {
    // myAppName: 'egg',
    sequelize: {
      dialect: "mysql",
      host: "127.0.0.1",
      port: 3306,
      username: "root",
      password: "",
      database: "kaikeba"
    }
  };

  return {
    ...config,
    ...userConfig,
  };
};

plugin.js

'use strict';

/** @type Egg.EggPlugin */
module.exports = {
  // had enabled by egg
  // static: {
  //   enable: true,
  // }
   sequelize: {
    enable: true,
    package: 'egg-sequelize',
  }
};
