启动zookeeper

在kafka文件下启动命令窗口

输入:

.\bin\windows\zookeeper-server-start.bat .\config\zookeeper.properties

启动kafka

输入:

bin\windows\kafka-server-start.bat config\server.properties

启动类:

配置kafka

package main

import (
   "fmt"
   "github.com/Shopify/sarama"
)

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

bin\windows\kafka-console-consumer.bat  --bootstrap-server 127.0.0.1:9092 --topic shopping --from-beginning

shopping是Topic的值
