golang 结构体中的变量，添加匿名字段(struct)后的成员变量和成员方法的访问

package main

import (
	"fmt"
)

type Animal struct {
	Age int
}

type Person struct {
	Animal
	Sex int
}

func (animal *Animal) getAge() int {
	return animal.Age
}

func (animal *Animal) getName() string {
	return "animal"
}

func (person Person) getSexName() string {
	return "man"
}

func (person Person) getName() string {
	return "person"
}

func main() {
	var person Person
	person.Age = 20
	person.Sex = 1
	fmt.Println(person.getAge())
	fmt.Println(person.getSexName())
	fmt.Println(person.getName())
}

输出

20

成员变量，是指针类型

package main

import (
	"fmt"
)

type Animal struct {
	Age int
}

type Person struct {
	*Animal
	Sex int
}

func (animal *Animal) getAge() int {
	return animal.Age
}

func (animal *Animal) getName() string {
	return "animal"
}

func (person Person) getSexName() string {
	return "man"
}

func (person Person) getName() string {
	return "person"
}

func main() {
	var person = Person{&Animal{20}, 1}
	fmt.Println(person.getAge())
	fmt.Println(person.getSexName())
	fmt.Println(person.getName())
}
