Kafka事務奇怪的enable.idempotence屬性

在 KafkaProperties中配置沒有發現配置參數

• enable.idempotence 也就是說沒有辦法通過直接配置開啟,也就無法使用事物,當然可以選擇手動配置Kafka

@ConfigurationProperties(
    prefix = "spring.kafka"
)
public class KafkaProperties {
    private List<String> bootstrapServers = new ArrayList(Collections.singletonList("localhost:9092"));
    private String clientId;
    private final Map<String, String> properties = new HashMap();
    private final KafkaProperties.Consumer consumer = new KafkaProperties.Consumer();
    private final KafkaProperties.Producer producer = new KafkaProperties.Producer();
    private final KafkaProperties.Admin admin = new KafkaProperties.Admin();
    private final KafkaProperties.Streams streams = new KafkaProperties.Streams();
    private final KafkaProperties.Listener listener = new KafkaProperties.Listener();

但是 Spring Boot Kafka 聽下面兩個配置會自動開啟冪等性

spring.kafka.consumer.isolation-level=read_committed
spring.kafka.producer.transaction-id-prefix=test
