添加依赖

compile("org.springframework.kafka:spring-kafka:1.1.2.RELEASE")

添加application.properties

#kafka# 指定kafka 代理地址，可以多个spring.kafka.bootstrap-servers=192.168.59.130:9092,192.168.59.131:9092,192.168.59.132:9092# 指定默认消费者group idspring.kafka.consumer.group-id=myGroup# 指定默认topic idspring.kafka.template.default-topic= my-replicated-topic# 指定listener 容器中的线程数，用于提高并发量spring.kafka.listener.concurrency= 3# 每次批量发送消息的数量spring.kafka.producer.batch-size= 1000
