这是Chelsea.M1 版本的 binder 和 Spring Initializr 之间的不一致——Kafka binder starter 需要 0.9 依赖集作为基线，但 Spring Boot 父级将 Spring Kafka 依赖项覆盖到 1.1.2.由于 Spring Integration Kafka 不受 Spring Boot 管理，因此由 binder 拉入的版本 - 2.0.1 - 与 Spring Kafka 1.1.2 不兼容.

This is an inconsistency between the Chelsea.M1 release of the binder and Spring Initializr - the Kafka binder starter requires the 0.9 dependency set as a baseline, but the Spring Boot parent overrides the Spring Kafka dependency to 1.1.2. Since Spring Integration Kafka is not managed by Spring Boot, the version that's pulled in by the binder - 2.0.1 - is incompatible to Spring Kafka 1.1.2.

更新:如果在 Initializr 中使用 Spring Boot 1.5.2.BUILD-SNAPSHOT 及更高版本，则应检索正确的依赖项集.请注意，需要 Kafka 0.10.1.x.

Update: If using version Spring Boot 1.5.2.BUILD-SNAPSHOT and later in Initializr, the proper dependency set should be retrieved. Note that a Kafka 0.10.1.x is required.
