我是 kafka、springboot 的新手，正在尝试将 kafka 和 elasticsearch 集成到我的 springboot 应用程序中。

当我尝试运行 springboot 应用程序时，我看到以下错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'kafkaListenerContainerFactory' defined in class path resource [org/springframework/boot/autoconfigure/kafka/KafkaAnnotationDrivenConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.kafka.config.ConcurrentKafkaListenerContainerFactory]: Factory method 'kafkaListenerContainerFactory' threw exception; nested exception is java.lang.NoSuchMethodError:org.springframework.kafka.config.ConcurrentKafkaListenerContainerFactory.getContainerProperties()Lorg/springframework/kafka/listener/config/ContainerProperties;

我的 pom.xml

生产者类

@Service
public class Producer {
    private static final Logger logger = LoggerFactory.getLogger(Producer.class);
    private static  final  String topic = "users";

    @Autowired
    private KafkaTemplate<String, String> kafkaTemplate;

    public void sendMessage(History t){
        logger.info("Inside send message to topic");
        this.kafkaTemplate.send(topic,"HelloWorld");
    }

}

消费者.java

package com.springboot.kafka;

import com.springboot.model.History;
import com.springboot.repository.HistoryRepository;
import org.apache.kafka.common.protocol.types.Field;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.kafka.annotation.KafkaListener;
import org.springframework.stereotype.Service;

@Service
public class Consumer  {
    private static final Logger logger = LoggerFactory.getLogger(Consumer.class);
    private static  final  String topic = "users";


    @KafkaListener(topics = topic,groupId = "group-id")
    public void consume (String t){
        logger.info("Message read as " + t);

    }
}

关于我遗漏了什么的任何想法。任何线索将不胜感激。

最佳答案

您应该检查完整的错误日志(堆栈跟踪)。在我的例子中，问题是由下面的 java.io.FileNotFoundException 引起的。
您通常会在堆栈跟踪的末尾发现您的“真正”问题。

关于java - 创建名为“kafkaListenerContainerFactory”的 bean 时出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58234179/
