Question

我正在开发一个示例Spring集成项目，该项目具有使用spring集成的kafka监听器。这对于较低版本的引导（引导-1.5.9，kafka-client 1.0.0，spring-integration-kafka 2.3.0，spring-kafka 1.3.2）工作正常。但是在将引导版本从1.5.9升级到2.1.x时遇到错误：-

mvn依赖树：-

mvn dependency:tree | find "kafka"
[INFO] +- org.apache.kafka:kafka-clients:jar:2.0.1:compile
[INFO] +- org.springframework.integration:spring-integration-kafka:jar:2.3.0.RELEASE:compile
[INFO] +- org.springframework.kafka:spring-kafka:jar:2.2.4.RELEASE:compile

请为引导版本2.1.x或2.2.x建议一个可用的pom，以便它运行时不会出错。我正在使用的主要工件：-kafka-clients，spring-integration-kafka，spring-kafka和spring-boot-starter-integration（所有这些都由boot提供它们自己的版本，除了spring-integration-kafka以外没有明确提及（ 2.3.0））。

Answer 1

在引导2.1.x上使用3.1.5-最新的3.1.x，在引导2.2.x上使用3.2.1-请参见compatibility matrix here。

Spring Integration Kafka仍然是一个扩展，它的版本不受引导管理，因为它具有更快的发布节奏。

它将很快被拖入主项目。
