SpringBoot+Kafka+策略模式_spring-kafka自定义分区策略

1.pom引入依赖

        <dependency>
            <groupId>org.springframework.kafka</groupId>
            <artifactId>spring-kafka</artifactId>
        </dependency>

2.yml文件增加配置

spring:
   kafka:

      bootstrap-servers: localhost:9092
      producer:
         # 重试次数
         retries: 0
         # 应答级别:多少个分区副本备份完成时向生产者发送ack确认(可选0、1、all/-1)
         acks: 1
         # 批量大小
         batch-size: 16384
         # 生产端缓冲区大小
         buffer-memory: 33554432
         key-serializer: org.apache.kafka.common.serialization.StringSerializer
         value-serializer: org.apache.kafka.common.serialization.StringSerializer
         properties:
            max.request.size: 5242880
      consumer:
         # 默认消费者组
         group-id: test

         # 最早未被消费的offset
         auto-offset-reset: earliest
         enable-auto-commit: true
         # 批量一次最大拉取数据量
         # max-poll-records: 1000
         # 自动确认offset的时间间隔
         auto-commit-interval: 1000
         # key的序列化类

      # 消费监听接口监听的主题不存在时
