)

type MainController struct {
    beego.Controller
}

func (this *MainController) Get() {
    this.Ctx.WriteString("Hello World")
}

func main() {
    beego.Router("/", &MainController{})
    beego.Run()
}

3. GORM

    _ "github.com/jinzhu/gorm/dialects/mysql"
)

type User struct {
    ID   uint
    Name string
}

func main() {
    db, err := gorm.Open("mysql", "user:password@/dbname?charset=utf8&parseTime=True&loc=Local")
    if err != nil {
        panic("failed to connect database")
    }
    defer db.Close()

    db.AutoMigrate(&User{})

    user := User{Name: "Alice"}
    db.Create(&user)

    var result User
    db.First(&result, user.ID)
    fmt.Println(result)
}

4. GoConvey

GoConvey is a convenient Go language testing framework. It provides intuitive test result display and is easy to write and Read the test code. The following is an example of using GoConvey to write test cases:

package main

import (
    . "github.com/smartystreets/goconvey/convey"
    "testing"
)

func TestAdd(t *testing.T) {
    Convey("Given two numbers", t, func() {
        a := 1
        b := 2

        Convey("When adding them together", func() {
            c := a + b

            Convey("The result should be correct", func() {
                So(c, ShouldEqual, 3)
            })
        })
    })
}

5. GinSwagger

    r := gin.New()
    r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerFiles.Handler))
    r.Run()
}

The above are the five recommended Go language projects, which are Gin, Beego, GORM, GoConvey and GinSwagger. These projects have outstanding features and functions in their respective fields, providing Go language developers with a convenient and efficient development experience. We hope that the content of this article can help readers gain a deeper understanding of these projects and apply them in actual project development.
