特征 | Features

• 支持原生：支持spring-kafka原生配置。

spring:
  kafka:
    bootstrap-servers: localhost:9092
    consumer:
      key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      value-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      auto-offset-reset: earliest
    producer:
      key-serializer: org.apache.kafka.common.serialization.StringSerializer
      value-serializer: org.apache.kafka.common.serialization.StringSerializer

• 支持多数据源：支持多数据源配置。（配置粒度越小，优先级越高，遵循就近原则）

spring:
  kafka:
    multiple:
      # Primary data source is not allowed to be empty.
      primary: ds1  
      consumer:
        key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
        value-deserializer: org.apache.kafka.common.serialization.StringDeserializer
        auto-offset-reset: latest
      producer:
        key-serializer: org.apache.kafka.common.serialization.StringSerializer
        value-serializer: org.apache.kafka.common.serialization.StringSerializer
      datasource:
        ds1:
          bootstrap-servers: localhost:9092
          consumer:
            # Consumer concurrent kafka listener container factory is not allowed to be empty.
            container-factory: ds1KafkaListenerContainerFactory  
            auto-offset-reset: earliest
          producer:
            kafka-template: ds1KafkaTemplate
        ds2:
          bootstrap-servers: localhost:9093
          consumer:
            container-factory: ds2KafkaListenerContainerFactory
            auto-offset-reset: earliest
          producer:
            # Producer kafka template bean name is not allowed to be empty.
            kafka-template: ds2KafkaTemplate
