Spring 클라우드 데이터 흐름 샘플 소스를 실행할 때 DestinationReslutionException이 발생했습니다.

Question

샘플 spring-cloud-dataflow 소스 애플리케이션을 실행하는 데 문제가 있습니다. 코드 0으로 응용 프로그램이 종료됩니다 (작동 중이어야합니다). 나는 그것을 디버깅하고 다음과 같은 예외가 발생되는 것을 발견 :

DestinationResolutionException: failed to look up MessageChannel with name 'output' 

내가 시작 설명서 http://docs.spring.io/spring-cloud-stream/docs/current/reference/htmlsingle/index.html#_getting_started을 follownig하고 있었고, 난 그것을 작동 얻을 수 없습니다. 내가 한 짓 : - 나는 사육사가 일하고있다. - 카프카가 있습니다.

코드 :

import org.springframework.cloud.stream.annotation.EnableBinding; 
import org.springframework.cloud.stream.messaging.Source; 
import org.springframework.integration.annotation.InboundChannelAdapter; 

@EnableBinding(Source.class) 
public class SampleSource { 

    @InboundChannelAdapter(Source.OUTPUT) 
    public String greet() { 
     return "hello world " + System.currentTimeMillis(); 
    } 
} 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.context.ConfigurableApplicationContext; 

@SpringBootApplication 
public class SampleSourceApplication { 

    public static void main(String[] args) { 
     try (ConfigurableApplicationContext run = SpringApplication.run(SampleSourceApplication.class, args)) { 
     } 
    } 
}

기본 응용 프로그램에서 SampleSource 클래스를 가져 오지 못했습니다. SampleSource 클래스가 SampleSourceApplication 패키지와 같은 패키지에 있습니까?
