BeanNotOfRequiredTypeException：名为“输入流名称”的Bean的类型应为“ org.springframework.messaging.SubscribableChannel

Question

我正在尝试对流式Kafka代码进行单元测试，运行单元测试时出现以下错误 由以下原因引起：org.springframework.beans.factory.BeanNotOfRequiredTypeException：名为“ input-stream-name”的Bean的类型应为“ org.springframework.messaging.SubscribableChannel

public interface TestStream {
    @Input(TestStreamInputOutput.INPUT)
    SubscribableChannel inboundTestMessageRequest();

    @Output(TestStreamInputOutput.OUTPUT)
    MessageChannel outboundTestStatusResponse();
}

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("stream")
public class TestStreamServiceImplTest {

    @Autowired
    private TesttreamServiceImpl testStreamServiceImpl;

    @MockBean
    private TestStream  testStream;

    @Mock
    private MessageChannel messageChannel;

    @Test
    public void pushAwsEmailStatus_When_Dto_Not_Null_Success()
    {

        Optional<TestStatusDetailDto> testStatusDetailsDto = Optional.ofNullable(
                TestStatusDetailDto.newBuilder()
                .setMessageId("1234").setMessageStatus(TestStatusDetailDto.Sent).build());

        Mockito.when(testStream.outboundTestStatusResponse()).thenReturn(messageChannel);
        Mockito.when(messageChannel.send(Mockito.any(Message.class))).thenReturn(true);
        testStreamServiceImpl.pushTestStatus(testStatusDetailsDto);
        Mockito.verify(messageChannel,Mockito.times(1)).send(Mockito.any(Message.class));
    }
}

输入kafka

spring.cloud.stream.bindings.input-stream-name.contentType = application / * + avro spring.cloud.stream.bindings.input-stream-name.destination = icom-in-message-status-events

输出kafka
