go语言os.exit(1)_Go语言－信号os.Interrupt和信号syscall.SIGTERM的应用
實(shí)例
package main
import(
"fmt"
"os"
"os/signal"
"sync"
"syscall"
"time"
)
func worker(stop
for {
select {
case
fmt.Println("exit")
return
default:
fmt.Println("running...")
time.Sleep(3)
}
}
}
func main() {
stop := make(chan bool)
var wg sync.WaitGroup
for i := 0; i < 3; i++ {
wg.Add(1)
go func(stop
defer wg.Done()
worker(stop)
}(stop)
}
waitForSignal()
close(stop)
fmt.Println("stopping all job")
wg.Wait()
}
func waitForSignal() {
sigs := make(chan os.Signal)
signal.Notify(sigs, os.Interrupt)
signal.Notify(sigs, syscall.SIGTERM)
fmt.Println(
}
運(yùn)行結(jié)果
pkill信號(hào)syscall.SIGTERM
...
running...
running...
running...
running...
terminated
running...
running...
stopping all job
exit

或者ctrl+c信號(hào)os.Interrupt
