golang iris mvc实现表增删改查源代码,包含router/model/service/controller/config

很高兴回答这个问题。以下是一个基于Go语言Iris框架的MVC（模型-视图-控制器）架构的源代码实现：

1、router.go:

package router

import (
    "github.com/kataras/iris/v12"
    "myproject/controller"
)

func Router(app *iris.Application) {
    userController := controller.UserController{}
    app.Handle("GET", "/users", userController.GetAll)
    app.Handle("GET", "/user/{id}", userController.GetByID)
    app.Handle("POST", "/user", userController.Create)
    app.Handle("PUT", "/user/{id}", userController.UpdateByID)
    app.Handle("DELETE", "/user/{id}", userController.DeleteByID)
}

2、model.go:

package model

import (
    "gorm.io/driver/mysql"
    "gorm.io/gorm"
    "myproject/config"
)

var (
    DB *gorm.DB
)

func Init() {
    dsn := config.GetDSN()
    var err error
    DB, err = gorm.Open(mysql.Open(dsn), &gorm.Config{})
    if err != nil {
        panic(err)
    }
    DB.AutoMigrate(&User{})
}

type User struct {
    gorm.Model
    Name string `gorm:"type:varchar(32)"`
    Age  int    `gorm:"default:18"`
}

func (u *User) TableName() string {
    return "users"
}

3、service.go:

package service

import (
    "myproject/model"
)

type UserService struct{}

func (us *UserService) GetAll() []*model.User {
    var users []*model.User
    model.DB.Find(&users)
    return users
}

func (us *UserService) GetByID(id int) *model.User {
    user := &model.User{}
    model.DB.First(user, id)
    return user
}

func (us *UserService) Create(user *model.User) {
    model.DB.Create(user)
}

func (us *UserService) UpdateByID(id int, user *model.User) {
    model.DB.Model(&model.User{}).Where("id=?", id).Updates(&user)
}

func (us *UserService) DeleteByID(id int) {
    model.DB.Delete(&model.User{}, id)
}

4、controller.go:

package controller

import (
    "github.com/kataras/iris/v12"
    "myproject/model"
    "myproject/service"
    "strconv"
)

type UserController struct{}

func (uc *UserController) GetAll(ctx iris.Context) {
    userService := &service.UserService{}
    result := userService.GetAll()
    ctx.JSON(result)
}

func (uc *UserController) GetByID(ctx iris.Context) {
    userService := &service.UserService{}
    id, _ := strconv.Atoi(ctx.Params().Get("id"))
    result := userService.GetByID(id)
    ctx.JSON(result)
}

func (uc *UserController) Create(ctx iris.Context) {
    userService := &service.UserService{}
    user := &model.User{}
    ctx.ReadJSON(&user)
    userService.Create(user)
}

func (uc *UserController) UpdateByID(ctx iris.Context) {
    userService := &service.UserService{}
    user := &model.User{}
    id, _ := strconv.Atoi(ctx.Params().Get("id"))
    ctx.ReadJSON(&user)
    userService.UpdateByID(id, user)
}

func (uc *UserController) DeleteByID(ctx iris.Context) {
    userService := &service.UserService{}
    id, _ := strconv.Atoi(ctx.Params().Get("id"))
    userService.DeleteByID(id)
}

5、config.go:

package config

func GetDSN() string {
    return "root:123456@tcp(127.0.0.1:3306)/mydb?charset=utf8mb4&parseTime=True&loc=Local"
}

这是一份基础的代码实现，你可以根据你的需求进行相应的修改和优化。希望对你有帮助。
