目录结构

手动创建一个mvc目录结构

datamodels：只存放结构体
repositories：数据库相关操作文件
services：业务逻辑以上三个文件夹可以综合为M层
web
- controllers ：控制器层 C
- views ：视图层 V

下载Iris框架：go get github.com/kataras/iris/v12@master

入口文件

入口文件为根目录下 main.go

main.go :

package main

import (
	"github.com/kataras/iris/v12"
	"github.com/kataras/iris/v12/mvc"
	"iris/web/controllers"
)

func main()  {
	//新建iris
	app:=iris.New()
	//设置错误等级
	app.Logger().SetLevel("debug")
	//注册模板目录
	app.RegisterView(iris.HTML("./web/views",".html"))
	//注册控制器
	mvc.New(app.Party("/hello")).Handle(new(controllers.BookController))
	//启动服务
	app.Run(
		iris.Addr("localhost:8080"), //监听8080端口
	)
}

datamodels\book.go

package datamodels

type Book struct {
	Name string
}

repositories\book_repository.go

package repositories

import "iris/datamodels"

type BookRepository interface {
	GetBookName() string
}

type BookManager struct {
}

func NewBookManager() BookRepository {
	return &BookManager{}
}

func (m *BookManager) GetBookName() string {
	//模拟赋值给模型
	book := &datamodels.Book{Name: "微客鸟窝"}
	return book.Name
}

services\book_service.go

package services

import (
	"fmt"
	"iris/repositories"
)

type BookService interface {
	ShowBookName() string
}

type BookServiceManger struct {
	repo repositories.BookRepository
}

func NewBookServiceManger(repo repositories.BookRepository) BookService {
	return &BookServiceManger{repo:repo}
}

func (m *BookServiceManger) ShowBookName() string {
	fmt.Println("获取的名称为："+m.repo.GetBookName())
	return "获取的名称为："+m.repo.GetBookName()
}

web\controllers\book_controller.go

package controllers

import (
	"github.com/kataras/iris/v12/mvc"
	"iris/repositories"
	"iris/services"
)

type BookController struct{

}

func (c *BookController) Get() mvc.View {
	bookRepository := repositories.NewBookManager()
	bookService := services.NewBookServiceManger(bookRepository)
	BookResult := bookService.ShowBookName()
	return mvc.View{ //渲染模板
		Name:"/book/index.html",
		Data:BookResult,
	}
}

web\views\book\index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h2>{{.}}</h2>
</body>
</html>

运行go run main.go

浏览器方问 http://localhost:8080/hello

一个简单的 iris mvc 例子就此完成，其中数据流程需要好好屡清楚。希望对诸位有所帮助。
