SpringBean注入在OpenShift上失败

我在我们的Spring引导应用程序中添加了一个新的Spring集成配置和Spring消息传递。 应用程序在我的MAC上正确部署和运行

但是,， 部署到OpenShift（使用OpenJDK）或Docker运行时时 部署失败，出现以下错误：

Unsatisfied dependency expressed through constructor parameter 0;
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type 'org.springframework.messaging.MessageChannel' available:
expected at least 1 bean which qualifies as autowire candidate.
Dependency annotations:
{@org.springframework.beans.factory.annotation.Qualifier(value=ftpChannel)}

下面是代码的简化版本，失败时出现相同错误：

import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.messaging.MessageChannel;
import org.springframework.stereotype.Service;


@Service
public class FtpService {

    private final MessageChannel ftpClientInboundChannel;

    public FtpService(@Qualifier("ftpChannel") MessageChannel ftpClientInboundChannel) {
        this.ftpClientInboundChannel = ftpClientInboundChannel;
    }
}

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.integration.annotation.IntegrationComponentScan;
import org.springframework.integration.annotation.ServiceActivator;
import org.springframework.messaging.Message;
import org.springframework.messaging.MessageHandler;
import org.springframework.messaging.MessagingException;


@Configuration
@IntegrationComponentScan
public class FtpClientConfiguration {

    @Bean
    @ServiceActivator(inputChannel = "ftpChannel")
    public MessageHandler ftpPayableHandler() {

        return new MessageHandler() {
            @Override
            public void handleMessage(Message<?> message) throws MessagingException {

            }
        };
    }

}

import org.springframework.beans.factory.annotation.Qualifier；
导入org.springframework.messaging.MessageChannel；
导入org.springframework.stereotype.Service；
@服务
公共类FTP服务{
私有最终消息通道ftpClientInboundChannel；
公共FTP服务（@Qualifier（“ftpChannel”）消息通道ftpClientInboundChannel）{
this.ftpClientInboundChannel=ftpClientInboundChannel；
}
}
导入org.springframework.context.annotation.Bean；
导入org.springframework.context.annotation.Configuration；
导入org.springframework.integration.annotation.IntegrationComponentScan；
导入org.springframework.integration.annotation.ServiceActivator；
导入org.springframework.messaging.Message；
导入org.springframework.messaging.MessageHandler；
导入org.springframework.MessagingException；
@配置
@集成组件扫描
公共类FtpClientConfiguration{
@豆子
@ServiceActivator（inputChannel=“ftpChannel”）
public MessageHandler ftpPayableHandler（）{
返回新的MessageHandler（）{
@凌驾
public void handleMessage（消息消息消息）引发MessaginException{
}
};
}
}

通过添加消息通道bean解决了该问题：

@Bean
public MessageChannel ftpChannel() {
    return new DirectChannel();
}
