【解决方案1】：

setShooter 只不过是某个 Sequelize 模型类中的一个函数

例如

import Sequelize from 'sequelize'

export default class Product extends Sequelize.Model {

    // model init
    static init(sequelize) {
        return super.init({
                name: { type: Sequelize.STRING(128), allowNull: false },
                description: { type: Sequelize.TEXT, allowNull: false }
            },
            {
                sequelize,
                tableName: 'c_products'
            })
    }

    setShooter() {
        console.log('Hello World!')
    }

}
