Question

我有一个工作原型Spring Boot应用程序，它侦听Kafka队列。除了shared_ptr<int> sptr;中的配置外，所需要的只是application.yml使用MessageListener注释的实现。

我现在介绍Spring Integration，并且已经配置了这些bean：

@KafkaListener

应用程序未启动，并且抛出此错误：

@Bean
public KafkaMessageDrivenChannelAdapter<String, String>
adapter(KafkaMessageListenerContainer<String, String> container) {
    KafkaMessageDrivenChannelAdapter<String, String> kafkaMessageDrivenChannelAdapter =
            new KafkaMessageDrivenChannelAdapter<>(container);
    kafkaMessageDrivenChannelAdapter.setOutputChannel(receiver());
    return kafkaMessageDrivenChannelAdapter;
}

@Bean
public KafkaMessageListenerContainer<String, String> container() throws Exception {
    ContainerProperties properties = new ContainerProperties(this.topic);
    // set more properties
    return new KafkaMessageListenerContainer<>(consumerFactory(), properties);
}

@Bean
public ConsumerFactory<String, String> consumerFactory() {
    Map<String, Object> props = ...; // set proerties
    return new DefaultKafkaConsumerFactory<>(props);
}

即使我已经定义了Parameter 1 of method kafkaListenerContainerFactory in org.springframework.boot.autoconfigure.kafka.KafkaAnnotationDrivenConfiguration required a bean of type 'org.springframework.kafka.core.ConsumerFactory' that could not be found. - Bean method 'kafkaConsumerFactory' in 'KafkaAutoConfiguration' not loaded because @ConditionalOnMissingBean (types: org.springframework.kafka.core.ConsumerFactory; SearchStrategy: all) found bean 'consumerFactory' Action: Consider revisiting the conditions above or defining a bean of type 'org.springframework.kafka.core.ConsumerFactory' in your configuration. bean。

在调试模式下运行，很明显Boot正在加载一个ConsumerFactory bean来监听代理：

KafkaListenerEndpointContainer

然后：

[org.springframework.kafka.KafkaListenerEndpointContainer#0-0-C-1] o.a.k.c.c.internals.AbstractCoordinator  : Discovered coordinator localhost:9092 (id: 2147483999 rack: null) for group my_group.

我认为发生的事情是Spring Boot \ Kafa自动配置与Spring Integration \ Kafka设置发生冲突。解决这个问题的正确方法是什么？

由于

Answer 1

您可以使用Boot的消费者工厂......

@Bean
public KafkaMessageListenerContainer<String, String> container(ConsumerFactory<String, String> cf) {
    ...
}

或禁用kafka自动配置

@SpringBootApplication(exclude = KafkaAutoConfiguration.class)

Spring Boot on Spring Boot的Kafka配置
