duffiye opened a new issue #465: [Native] Should shutdown producer when sended a message
URL: https://github.com/apache/rocketmq-client-go/issues/465
send a message like this：
```
func SendWithdrawalQueryMsg(message string, delayTimeLevel int) error {
p, _ := rocketmq.NewProducer(
producer.WithGroupName("ZB_WALLET_QUERY_GROUP"),
producer.WithNameServer(config.Config.Rocket.Servers),
producer.WithRetry(2),
)
err := p.Start()
if err != nil {
fmt.Printf("start producer error: %s", err.Error())
// os.Exit(1)
}
msg := primitive.NewMessage("ZB_QUERY_TOPIC", []byte(message))
if delayTimeLevel > 0 {
msg.WithDelayTimeLevel(delayTimeLevel)
}
res, err := p.SendSync(context.Background(), msg)
if err != nil {
fmt.Printf("send message error: %s\n", err)
util.DingTalkTextMsg(fmt.Sprintf("发送提现查询队列[ZB_QUERY_TOPIC]异常,ID[%s]", message), config.Config.Alert.Mobiles)
return err
}
fmt.Printf("发送提现查询队列 success: result=%s\n", res.String())
err = p.Shutdown()
if err != nil {
fmt.Printf("send message error: %s\n", err)
return err
}
return nil
}`
```
if send message again, then get error
`send message error: service close is not running, please check`
if there have no ` err = p.Shutdown()` works well, send message successful .
