)
func main() {
//1. 生产者配置
config := sarama.NewConfig()
config.Producer.RequiredAcks = sarama.WaitForAll //ACK
config.Producer.Partitioner = sarama.NewRandomPartitioner //分区
config.Producer.Return.Successes = true //确认
//2.连接kafka
client, err := sarama.NewSyncProducer([]string{"127.0.0.1:9092"}, config)
if err != nil {
fmt.Println("producer closed,err:", err)
return
}
defer client.Close()
//3. 封装消息
msg := &sarama.ProducerMessage{}
msg.Topic = "shopping"
msg.Value = sarama.StringEncoder("happy aaaa")
//4.发送消息
pid, offset, err := client.SendMessage(msg)
if err != nil {
fmt.Println("send msg failed,err:", err)
return
}
fmt.Printf("pid : %v offset : %v", pid, offset)
}
启动消费者
