Spring Cloud Stream App Starters
Spring Cloud Stream Application Starters是基於Spring Boot的Spring Integration應用程式，可提供與外部系統的整合。 Spring Cloud Stream應用程式可與Spring Cloud Data Flow一起使用，以建立，部署和編排訊息驅動的微服務應用程式。
Spring Cloud Stream Application Starters是獨立的可執行應用程式，可通過Apache Kafka和RabbitMQ等訊息傳遞中介軟體進行通訊。 這些應用程式可以在各種執行時平臺上獨立執行，包括：Cloud Foundry，Apache Yarn，Apache Mesos，Kubernetes，Docker，甚至可以在您的膝上型電腦上執行。
特性
- 獨立執行作為Spring Boot應用程式
- 將微服務組合為Spring Cloud Data Flow中的流管道
- 將微服務應用程式用作maven或docker工件
- 通過命令列，環境變數或YAML檔案覆蓋配置引數
- 提供基礎架構以單獨測試應用程式
- 從此版本的Spring Initializr下載為初學者

快速開始
第1步 - 從這裡下載最新的基於Kafka 10的時間源應用程式[例如：/1.3.0.RELEASE/time-source-kafka-10-1.3.0.RELEASE.jar]
第2步 - 從這裡下載最新的基於Kafka 10的日誌接收器應用程式[例如：/1.3.0.RELEASE/log-sink-kafka-10-1.3.0.RELEASE.jar]
第3步 - 啟動Kafka 0.10.1.1
第4步 - 執行時間源並繫結到ticktock主題
java -jar time-source-kafka-***.jar --spring.cloud.stream.bindings.output.destination=ticktock
第5步 - 執行Log Sink並繫結到ticktock主題
java -jar log-sink-kafka-***.jar --spring.cloud.stream.bindings.input.destination=ticktock
第6步- 在控制檯中驗證ticktock日誌
