golang中method的继承与重写

package main

import "fmt"

type Human struct {
	name  string
	age   int
	phone string
}
type student struct {
	Human
	school string
}
type Employee struct {
	Human
	company string
}

func (h *Human) sayHi() {
	fmt.Printf("Hi, i am %s you can call me on%s \n", h.name, h.phone)
}
func main() {
	mark := student{Human{"Mark", 25, "222-222"}, "MIT"}
	sam := Employee{Human{"sam", 45, "111-888"}, "golang inc"}
	mark.sayHi()
	sam.sayHi()
}

go的一个神奇之处，method也是可以继承的，如果匿名字段实现了一个method,那么包含这个匿名字段的struct也能调用该method。和匿名字段冲突一样的道理，我们可以重写一个匿名字段，实现

package main

import "fmt"

type Human struct {
	name  string
	age   int
	phone string
}
type student struct {
	Human
	school string
}
type Employee struct {
	Human
	company string
}

func (h *Human) sayHi() {
	fmt.Printf("Hi,i am %s you can call me on %s\n", h.
