Golang动态生成初始化数据（Beego框架）

对应控制器 controllers/IndexController.go

package controllers

import (
    "BeegoAdmin/models"
    "github.com/astaxie/beego"
)

type IndexController struct {
    beego.Controller
}

// 初始化后台框架接口
func (c *IndexController) SystemInit() {
    systemInit := new(models.SystemMenu).GetSystemInit()
    c.Data["json"] = systemInit
    c.ServeJSON()
}

对应Model models/SystemMenu.go

package models

    "github.com/astaxie/beego/orm"
    "time"
)

// 菜单

// 初始化结构体

        Image string `json:"image"`

// 菜单结构体

}

// 获取初始化数据

// 获取菜单列表

//递归获取子菜单
