golang goroutine 父子关系

很多人认为 父 goroutine 结束后 子goroutine 一定会结束

结论只要main 不结束 goroutine 一定会运行

代码验证

package main

import (
	"fmt"
	"time"
)

func main() {

	fmt.Println("main start")
	go func() {
		fmt.Println("parent start")
		go func() {
			fmt.Println("son start")
			time.Sleep(1 * time.Second)
			fmt.Println("son start")
		}()
		fmt.Println("parent end")
	}()
	time.Sleep(3 * time.Second)
	fmt.Println("main end")
}
/*main start
parent start
parent end
son start
son start
main end*/
