Question

我正在使用SpringXD，我有以下配置：

spring-integration-kafka 2.1.0.RELEASE
kafka-clients 0.10.0.1
Kafka 0.10.x.x
弹簧XD-1.3.1.RELEASE

我的xml文件中有以下配置：

                        <entry key="value.deserializer" value="org.apache.kafka.common.serialization.StringDeserializer" />

        <constructor-arg>
            <bean class="org.springframework.kafka.listener.config.ContainerProperties">
                <constructor-arg name="topics" value="testing-topic" />
            </bean>
        </constructor-arg>
    </bean>

</beans>

这是我用来启动/停止频道的Java类：

package com.kafka.source.logic;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import org.springframework.messaging.MessageChannel;
import org.springframework.messaging.support.GenericMessage;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;

@Configuration
@EnableScheduling
@ImportResource("classpath:/config/kafka-source-context.xml")
public class KafkaSourceRetry {

    @Autowired
    MessageChannel input;

    @Scheduled(cron="*/50 * * * * *")
    void startAdapter(){
        //CODE COMMENTED OUT TO MAKE SURE THE ADAPTER IS NOT BEING STARTED
        //EVEN IF I UNCOMMENT THE CODE, THE 50 secs defined related to the cron are not respected.
        //That is, if I send a message to the topic, it is inmediately consumed
        //input.send(new GenericMessage<String>("@kafka-inbound-channel-adapter-testing.start()"));
    }
}

然后我创建了一个基本流来检查我发送给该主题的某些消息是否正在通过

stream create --name bridgeStream --definition "kafkaSourceLatestApi_v2|bridge|file" --deploy

我检查了创建的文件，它包含了我发送给Kafka主题的所有消息：

hola_que_tal que_bonito bridgeStream.out（END）

同样在日志中我发现了这个：

我的问题是：为什么频道会自动启动？

Answer 1

它是这样设计的;所有模块都将自动启动设置为false，这样它们就不会出现故障;部署流时，将部署各个模块并从右向左启动。

部署/取消部署是启动/停止流的方式。

See the ModuleDeployer

SpringXD：auto-startup = false不能在Kafka消息驱动通道适配器上工作
