如何在选择 Golang 框架时考虑可选功能和集成？

import (
    "fmt"
    "gorm.io/driver/mysql"
    "gorm.io/gorm"
)

// User 模型
type User struct {
    ID       uint
    Username string
}

func main() {
    dsn := "username:password@tcp(localhost:3306)/database"
    db, err := gorm.Open(mysql.Open(dsn), &gorm.Config{})
    if err != nil {
        panic(err)
    }

    // 迁移（创建表）
    db.AutoMigrate(&User{})

    // 插入数据
    user := &User{Username: "johndoe"}
    db.Create(user)

    // 查询数据
    var users []User
    db.Find(&users)
    for _, user := range users {
        fmt.Println(user.Username)
    }
}

import (
    "context"
    "log"
    "net/http"

    "github.com/go-chi/chi"
)

func main() {
    r := chi.NewRouter()
    // 日志记录中间件
    r.Use(func(next http.Handler) http.Handler {
        return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
            log.Printf("%s %s %s", r.Method, r.URL.Path, r.RemoteAddr)
            next.ServeHTTP(w, r)
        })
    })

    // 路由
    r.Get("/", func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte("Hello World!"))
    })

    http.ListenAndServe(":8080", r)
}
