Kafka的安装与启动
安装Kafka在mac上,使用brew install kafka命令进行安装。若无Zookeeper,Kafka会自动安装。财运2棋牌源码
启动Kafka前,先启动Zookeeper。牙科客户系统源码进入Kafka安装目录下的bin目录,执行以下命令:./zookeeper-server-start /usr/local/etc/kafka/zookeeper.properties &(确保后台运行)。
启动Kafka使用brew services start kafka命令(在任意路径)。
创建话题topic,执行命令:kafka-topics --create --zookeeper localhost: --replication-factor 1 --partitions 1 --topic 你的topic名字。
创建话题后,使用kafka-topics --list --zookeeper localhost:命令查看已创建的opencv 增强现实源码话题。
接下来,创建生产者向话题传入数据。使用命令:kafka-console-producer --broker-list localhost: --topic 话题名字。地陪app源码
注意:原始参数为Zookeeper地址端口localhost:,Kafka服务器地址为localhost:。
根据以上步骤,spring aop源码下载对Kafka消费者进行配置,接受信息。详情请参考jianshu.com/p/ddd...
