MessageDeliveryException:Dispatcher没有订阅服务器

Question

我正在尝试使用spring-integration-kafka-2.1.0。在我公司的项目中发布。但是，由于下面列出的例外情况，它不起作用：org。springframework。信息。MessageDeliveryException:Dispatcher没有频道“org”的订户。springframework。网状物上下文WebApplicationContext:/order。“奥Kafka”。；嵌套的异常是org。springframework。整合。MessageDispatchingException:Dispatcher没有订阅服务器。

xml配置如下：ctx kafka producer。xml:

使用depend-depen属性在生产者之前初始化消费者。

Java代码如下：

制片人：

package com.angho.cloud.manager.kafka.impl;

import com.angho.cloud.bo.data.order.SyncOrderBO;
import com.angho.cloud.bo.result.order.CPosOrderSyncResult;
import com.angho.cloud.manager.kafka.CPosOrderSyncManager;
import com.angho.data.common.ResultConstant;
import org.apache.log4j.Logger;
import org.springframework.messaging.Message;
import org.springframework.messaging.MessageChannel;
import org.springframework.messaging.support.GenericMessage;


import javax.annotation.PostConstruct;
import javax.annotation.Resource;

public class CPosOrderKafkaProducer implements CPosOrderSyncManager {

    private static final Logger LOG = Logger.getLogger(CPosOrderKafkaProducer.class);

    @PostConstruct
    public void init(){
        System.out.println("KafkaProducer start...");
    }

    @Resource(name = "inputToKafka")
    private MessageChannel messageChannel;

    @Override
    public CPosOrderSyncResult sendToKafka(SyncOrderBO order) {
        CPosOrderSyncResult result = new CPosOrderSyncResult();
        result.setStatus(ResultConstant.CODE.ERROR);

        Message<SyncOrderBO> message = new GenericMessage<>(order);

        try {
            boolean flag = this.messageChannel.send(message);
            if (flag) {
                result.setStatus(ResultConstant.CODE.SUCCESS);
                result.setMessage(ResultConstant.MESSAGE.DEFAULT_SUCCESS_MESSAGE);
            } else {
                result.setMessage("Failed to send message to Kafka.");
            }
        } catch (Exception ex) {
            LOG.error(ex);
            result.setException(ex);
        }

        return result;
    }
}

生产者被定义为bean：

<bean id="kafkaOrderProducer" class="com.angho.cloud.manager.kafka.impl.CPosOrderKafkaProducer" depends-on="kafkaOrderConsumer"/>

消费者Java代码：

package com.angho.cloud.manager.kafka;

import org.springframework.integration.annotation.ServiceActivator;
import org.springframework.messaging.Message;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;

@Component("kafkaOrderConsumer")
public class KafkaOrderConsumer {

    @PostConstruct
    public void init(){
        System.out.println("what?KafkaConsumer start...");
    }

    @SuppressWarnings("unchecked")
    @ServiceActivator
    public void process(Message<?> message){
        System.out.println("Message =======>" + message);
        System.out.println("Content =======>" + message.getPayload());
    }
}

我不知道发生异常的原因。

我该怎么做才能让它工作？

PS：我试图通过xml而不是@Bean之类的Java代码来配置它。

原谅我糟糕的英语
。。。。。

非常感谢...

Answer 1

自动启动=false

你怎么会有那个？

适配器将不会订阅通道，直到它是start（）ed。
