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

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

// 菜单

	Id       int       `json:"id"`

	Href     string    `json:"href"`
	Sort     string    `json:"sort"`
	Target   string    `json:"target"`

	Status   int       `json:"status"`
	CreateAt time.Time `json:"create_at";orm:"auto_now;type(datetime)"`
}

func (m *SystemMenu) TableName() string {
	return TableName("system_menu")
}

// 初始化结构体
type SystemInit struct {
	HomeInfo struct {
		Title string `json:"title"`
		Href  string `json:"href"`
	} `json:"homeInfo"`
	LogoInfo struct {
		Title string `json:"title"`
		Image string `json:"image"`
	} `json:"logoInfo"`
	MenuInfo []*MenuTreeList `json:"menuInfo"`
}

// 菜单结构体
type MenuTreeList struct {
	Id     int             `json:"id"`
	Pid    int             `json:"pid"`

	Target string          `json:"target"`
	Remark string          `json:"remark"`

// 获取初始化数据

	// 首页
	systemInit.HomeInfo.Title = "首页"

	var menuList []SystemMenu
	_, _ = o.QueryTable(m.TableName()).Filter("status",1).OrderBy("-sort").All(&menuList)
	return m.buildMenuChild(0, menuList)

//递归获取子菜单
