今天给大家讲解下go语言开多进程。package mainimport (“fmt””time”)main() {c = make(chan int)go waiting(“coffee”, 1)go waiting(“tea”, 2)fmt.Println(“I,am waiting”)//time.Sleep(3 * time.Second)<-c<-c}func waiting(w string, sec int) {time.Sleep(time.Duration(sec) * time.Second)fmt.Println(w, “is ready”)c <- 1}
如果进程开的比较多，怎样去避免去写多个结束进程的channel，，下面我来给大家发下改进版：
package mainimport (“fmt””time”)main() {c = make(chan int)go waiting(“coffee”, 1)go waiting(“tea1”, 2)go waiting(“tea2”, 3)go waiting(“tea3”, 4)go waiting(“tea4”, 5)go waiting(“tea5”, 6)go waiting(“tea6”, 7)fmt.Println(“I,am waiting”)//time.Sleep(3 * time.Second)i := 0L:for {select {case <-c:i++if i > 6 {break L}}}}func waiting(w string, sec int) {time.Sleep(time.Duration(sec) * time.Second)fmt.Println(w, “is ready”)c <- 1}
