golang 子类调用父类函数

// testStruct project main.go

package main

import (

    "fmt"

)

type A struct {

    Text string

}

type Operator interface {

    Say()

}

func (a *A) Say() {

    fmt.Printf("A::Say():%s\n", a.Text)

}

type B struct {

    A

}

func (b *B) Say() {

    b.A.Say()

    fmt.Printf("B::Say():%s\n", b.Text)

}

func main() {

    b := B{}

    b.Text = "hello,world"

    b.Say()

}

A::Say():hello,world
B::Say():hello,world
