Question

我们在应用程序中使用Spring集成5.1.4和spring-boot-starter-integration 2.1.4。为了方便查看集成图，我们使用XML配置。现在，我们需要阅读来自kafka主题的消息，因此我们想使用最新的spring-integration-kafka 3.1.2.RELEASE版本和kafka入站通道适配器。我可以使用spring-integration-kafka 1.x版本找到示例xml配置，但是找不到最新版本的xml配置？如果我将旧的xml配置与3.x版一起使用，则会引发错误“找不到声明为int-kafka：zookeeper-connect元素的声明”。有人可以帮助我们指出版本兼容性矩阵的问题还是提供一些帮助可以从kafka主题读取的3.1.2 kafka入站通道适配器的示例xml配置。

<int-kafka:zookeeper-connect
    id="zookeeperConnect" zk-connect="localhost:2181"
    zk-connection-timeout="6000" zk-session-timeout="6000"
    zk-sync-time="2000" />

<int-kafka:inbound-channel-adapter
    id="kafkaInboundChannelAdapter"
    kafka-consumer-context-ref="consumerContext" auto-startup="true"
    channel="inputFromKafka">
    <int:poller fixed-delay="2000" time-unit="MILLISECONDS" />
</int-kafka:inbound-channel-adapter>

<bean id="consumerProperties"
    class="org.springframework.beans.factory.config.PropertiesFactoryBean">
    <property name="properties">
        <props>
            <prop key="auto.offset.reset">smallest</prop>
            <prop key="socket.receive.buffer.bytes">10485760</prop> <!-- 10M -->
            <prop key="fetch.message.max.bytes">5242880</prop>
            <prop key="auto.commit.interval.ms">1000</prop>
        </props>
    </property>
</bean>

<int-kafka:consumer-context
    id="consumerContext" consumer-timeout="1000"
    zookeeper-connect="zookeeperConnect"
    consumer-properties="consumerProperties">
    <int-kafka:consumer-configurations>
        <int-kafka:consumer-configuration
            group-id="Group1" max-messages="5000"
            key-decoder="deccoder" value-decoder="deccoder">
            <int-kafka:topic id="Helloworld-Topic" streams="3" />
        </int-kafka:consumer-configuration>
    </int-kafka:consumer-configurations>
</int-kafka:consumer-context>

<bean id="deccoder"
    class="org.springframework.integration.kafka.serializer.common.StringDecoder" />

请参见the documentation (a chapter in the Spring for Apache Kafka reference)。

<int-kafka:message-driven-channel-adapter
        id="kafkaListener"
        listener-container="container1"
        auto-startup="false"
        phase="100"
        send-timeout="5000"
        mode="record"
        retry-template="template"
        recovery-callback="callback"
        error-message-strategy="ems"
        channel="someChannel"
        error-channel="errorChannel" />

<bean id="container1" class="org.springframework.kafka.listener.KafkaMessageListenerContainer">
    <constructor-arg>
        <bean class="org.springframework.kafka.core.DefaultKafkaConsumerFactory">
            <constructor-arg>
                <map>
                <entry key="bootstrap.servers" value="localhost:9092" />
                ...
                </map>
            </constructor-arg>
        </bean>
    </constructor-arg>
    <constructor-arg>
        <bean class="org.springframework.kafka.listener.config.ContainerProperties">
            <constructor-arg name="topics" value="foo" />
        </bean>
    </constructor-arg>

</bean>

Spring Integration Kafka版本3.x中是否有任何xml配置可用于入站通道适配器
