标签： node.js lookback

【解决方案1】：

1) 数据源：

{
  "mysqlDB": {
    "host": "localhost",
    "port": 3306,
    "url": "",
    "database": "databse",
    "password": "",
    "name": "mysqlDB",
    "user": "root",
    "connector": "mysql"
   }
}

MySQL 默认使用端口 3306

2)配置模型：model-config.json

"users": {
    "dataSource": "mysqlDB",
    "public": true
  }

并移除Model中的内部函数

喜欢：

'use strict';

module.exports = function(Users) {

};
