使用 Gin-Plus 框架快速进行 web 开发

一、前言

安装

go get github.com/archine/gin-plus/v2@v2.0.0

# go.mod文件加入下面的一条
github.com/archine/gin-plus/v2 v2.0.0

# 命令行在该项目目录下执行
go mod tidy

二、项目使用

1、启动入口

定义 main 文件，作为项目启动入口

package main

import (
	"gin-plus-demo/base"
	_ "gin-plus-demo/controller"
	"github.com/archine/gin-plus/v2/ast"
	"github.com/archine/gin-plus/v2/mvc"
	log "github.com/sirupsen/logrus"
	"os"
)

//go:generate go run main.go ast
func main() {
	if len(os.Args) > 1 && os.Args[1] == "ast" {
		ast.Parse("controller") // controller目录
		return
	}
	app, err := base.NewApp("app.yml")
	if err != nil {
		log.Fatalf("initializer application failed,%s", err.Error())
	}
	mvc.Apply(app.Engine, true, base.Ast)
	app.Run()
}

2、定义数据库模型层

package model

import (
	"github.com/archine/ioc"
	log "github.com/sirupsen/logrus"
)

// User 和数据库对应得结构体
type User struct {
	Age  int
	Name string
}

// UserMapper 操作数据库层
type UserMapper struct{}

func (u *UserMapper) CreateBean() ioc.Bean {
	return &UserMapper{}
}

// AddUser 添加用户
func (u *UserMapper) AddUser(arg *User) {
	log.Printf("%v\n", arg)
}

// GetUser 获取用户
func (u *UserMapper) GetUser() *User {
	return &User{10, "张三"}
}

3、定义controller

package controller

import (
	"gin-plus-demo/model"
	"github.com/archine/gin-plus/v2/mvc"
	"github.com/archine/gin-plus/v2/resp"
	"github.com/gin-gonic/gin"
)

type TestController struct {
	mvc.Controller
	UserMapper *model.UserMapper `@autowired:""`
}

func init() {
	mvc.Register(&TestController{})
}

// User
// @GET(path="/user", globalFunc=false) 获取用户
func (t *TestController) User(ctx *gin.Context) {
	resp.Json(ctx, t.UserMapper.GetUser())
}

// AddUser
// @POST(path="/add_user", globalFunc=true) 添加用户
func (t *TestController) AddUser(ctx *gin.Context) {
	var arg model.User
	if resp.ParamValid(ctx, ctx.ShouldBindJSON(&arg), &arg) {
		return
	}
	t.UserMapper.AddUser(&arg)
	resp.Ok(ctx)
}
