Golang设计模式之桥接模式

创建文件Message.go

package bridge

// SNS短信
// Email
type AbstractMessage interface {
    SendMessage(text, to string) // 发送快，普通发送
}

type MessageImlementer interface {
    Send(text, to string) // 短信，邮件
}

创建文件MessageEmail.go

package bridge

import "fmt"

type MessageEmail struct {
}

func ViaEmail() MessageImlementer {
    return &MessageEmail{}
}

func (ms *MessageEmail) Send(text, to string) { // 邮件发送
    fmt.Printf("send %s to %s via Email\n", text, to)
}

创建文件MessageSMS.go

package bridge

import "fmt"

type MessageSMS struct {
}

func ViaSMS() MessageImlementer {
    return &MessageSMS{}
}

func (ms *MessageSMS) Send(text, to string) { // 短信发送
    fmt.Printf("send %s to %s via SMS\n", text, to)
}

创建文件UrgencyMessage.go

package bridge

import "fmt"

type UrgencyMessage struct {
    method MessageImlementer
}

func NewUrgencyMessage(method MessageImlementer) *UrgencyMessage {
    return &UrgencyMessage{method: method}
}

func (m *UrgencyMessage) SendMessage(text, to string) {
    m.method.Send(fmt.Sprintf("发送到[%s]", text), to) // 很快速度发送
}

main.go

package main

import "ssp_api_go/test/design/bridge"

func main() {
    m := bridge.NewUrgencyMessage(bridge.ViaEmail())
    m.SendMessage("你好", "Jackey")
}
