#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 id
spring.kafka.consumer.group-id=myGroup
# 指定默认topic id
spring.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
