GoFrame v2 development skill. Use only when the target Go project uses or is explicitly adopting GoFrame v2: the nearest go.mod requires github.com/gogf/gf/v2, existing Go files import github.com/gogf/gf/v2 or any github.com/gogf/gf/v2/... component package, or the user asks to scaffold, migrate, or build with GoFrame. Trigger for GoFrame-backed Go work such as APIs/controllers/services, middleware, routing/config, ORM/DAO/DO/entity/database operations, gf CLI/codegen, HTTP/gRPC services, and microservice conventions. Do not trigger for generic Go projects without GoFrame evidence, frontend-only work, shell scripts, or unrelated infrastructure tasks.

基本使用

package main

import (
    "github.com/gogf/gf/v2/container/gpool"
    "fmt"
    "time"
)

func main () {
    // 创建一个对象池,过期时间为1秒
    p := gpool.New(time.Second, nil)

    // 从池中取一个对象,返回nil及错误信息
    fmt.Println(p.Get())

    // 丢一个对象到池中
    p.Put(1)

    // 重新从池中取一个对象,返回1
    fmt.Println(p.Get())

    // 等待2秒后重试,发现对象已过期,返回nil及错误信息
    time.Sleep(2*time.Second)
    fmt.Println(p.Get())
}

创建及销毁方法

我们可以给定动态创建及销毁方法。

package main

import (
    "fmt"
    "github.com/gogf/gf/v2/container/gpool"
    "github.com/gogf/gf/v2/net/gtcp"
    "github.com/gogf/gf/v2/os/glog"
    "time"
)

func main() {
    // 创建对象复用池,对象过期时间为3秒,并给定创建及销毁方法
    p := gpool.New(3*time.Second, func() (interface{}, error) {
        return gtcp.NewConn("www.baidu.com:80")
    }, func(i interface{}) {
        glog.Println("expired")
        i.(*gtcp.Conn).Close()
    })
    conn, err := p.Get()
    if err != nil {
        panic(err)
    }
    result, err := conn.(*gtcp.Conn).SendRecv([]byte("HEAD / HTTP/1.1\n\n"), -1)
    if err != nil {
        panic(err)
    }
    fmt.Println(string(result))
    // 丢回池中以便重复使用
    p.Put(conn)
    // 等待一定时间观察过期方法调用
    time.Sleep(4*time.Second)
}

执行后,终端输出结果:

泛型使用示例

:::tip 版本要求:v2.10.0 :::

从 v2.10.0 版本开始,gpool 提供了泛型类型 TPool[T],无需类型断言,更加类型安全。

基本泛型使用

package main

import (
    "fmt"
    "time"
    
    "github.com/gogf/gf/v2/container/gpool"
)

func main() {
    // 创建一个泛型对象池,过期时间为1秒
    p := gpool.NewTPool[int](
        time.Second,
        nil, // 不指定创建方法
    )

    // 从池中取一个对象,返回零值及错误信息
    fmt.Println(p.Get())

    // 丢一个对象到池中
    p.Put(1)

    // 重新从池中取一个对象,返回 1
    fmt.Println(p.Get())

    // 等待2秒后重试,发现对象已过期,返回零值及错误信息
    time.Sleep(2 * time.Second)
    fmt.Println(p.Get())
}

泛型对象池示例

package main

import (
    "fmt"
    "time"
    
    "github.com/gogf/gf/v2/container/gpool"
    "github.com/gogf/gf/v2/net/gtcp"
    "github.com/gogf/gf/v2/os/glog"
)

func main() {
    // 创建对象复用池,对象过期时间为3秒,并给定创建及销毁方法
    p := gpool.NewTPool[*gtcp.Conn](
        3*time.Second,
        func() (*gtcp.Conn, error) {
            return gtcp.NewConn("www.baidu.com:80")
        },
        func(conn *gtcp.Conn) {
            glog.Println("expired")
            conn.Close()
        },
    )
    
    conn, err := p.Get()
    if err != nil {
        panic(err)
    }
    
    // 无需类型断言,conn 已经是 *gtcp.Conn 类型
    result, err := conn.SendRecv([]byte("HEAD / HTTP/1.1\n\n"), -1)
    if err != nil {
        panic(err)
    }
    fmt.Println(string(result))
    
    // 丢回池中以便重复使用
    p.Put(conn)
    
    // 等待一定时间观察过期方法调用
    time.Sleep(4 * time.Second)
}

自定义结构体示例

package main

import (
    "fmt"
    "time"
    
    "github.com/gogf/gf/v2/container/gpool"
)

type User struct {
    ID   int
    Name string
}

func main() {
    // 创建 User 对象池
    pool := gpool.NewTPool[*User](
        5*time.Second,
        func() (*User, error) {
            return &User{
                ID:   1,
                Name: "default",
            }, nil
        },
        func(user *User) {
            fmt.Printf("清理用户对象: %+v\n", user)
        },
    )
    defer pool.Close()

    // 获取对象
    user, err := pool.Get()
    if err != nil {
        panic(err)
    }
    
    // 直接使用,无需类型断言
    fmt.Printf("用户ID: %d, 名称: %s\n", user.ID, user.Name)
    
    // 修改对象
    user.ID = 100
    user.Name = "张三"
    
    // 放回池中复用
    pool.MustPut(user)
    
    // 再次获取,得到刚才修改的对象
    user2, _ := pool.Get()
    fmt.Printf("复用对象 - ID: %d, 名称: %s\n", user2.ID, user2.Name)
}

    The skill provides a comprehensive development guide and code examples for the GoFrame v2 framework. While highly informative for Go developers, it contains several examples with hardcoded placeholder secrets, tokens, and specific local file paths to sensitive configuration files (like Kubernetes credentials). These elements are provided for demonstration purposes but represent insecure practices if used in production without modification.

README badge

README badge for gogf/skills

Provides instruction and conventions for developing with GoFrame v2, a modular Go framework for building HTTP and gRPC services, microservices, and database operations using its ORM, CLI tooling, and project scaffolding. Use this skill when the target project has GoFrame v2 as a dependency or when the user requests scaffolding, migrations, or service development with GoFrame conventions.

Generated from the current SKILL.md.

When should I use this skill?
Use this skill only when your Go project uses GoFrame v2, indicated by github.com/gogf/gf/v2 in go.mod or imports. Do not use for generic Go projects, frontend work, or infrastructure tasks unrelated to GoFrame.
Should I manually set created_at and updated_at fields?
No. GoFrame automatically writes created_at on insert and updated_at on insert/update/save. Manually setting these fields is redundant and violates project conventions.
What should I use for database operations instead of g.Map?
Always use DO objects from internal/model/do/. DO struct fields are interface{}, unset fields remain nil and are automatically ignored by the ORM.
How does soft delete work in GoFrame?
Call Delete() on the DAO; GoFrame automatically converts it to UPDATE SET deleted_at = NOW(). Queries automatically filter out soft-deleted rows without requiring manual WhereNull conditions.
Where should I implement business logic?
Implement business logic directly in the service/ directory. Do not use the logic/ directory unless explicitly requested.
