我有4个bean，它们取决于我的应用程序的配置文件，现在我用qa配置文件运行我的应用程序：

@Bean
    @Profile("!qa")
    public ConsumerFactory<String, String> eventConsumerFactory() {
        return new DefaultKafkaConsumerFactory<>(saslConsumerConfig(eventConsumerConfig()));
    }

    @Bean
    @Profile("!qa")
    public ConsumerFactory<String, String> primeEmployeeConsumerFactory() {
        return new DefaultKafkaConsumerFactory<>(saslConsumerConfig(primeEmployeeConsumerConfig()));
    }

    @Bean
    @Profile("qa")
    public ConsumerFactory<String, String> simpleEventConsumerFactory() {
        return new DefaultKafkaConsumerFactory<>(eventConsumerConfig());
    }

    @Bean
    @Profile("qa")
    public ConsumerFactory<String, String> simplePrimeEmployeeConsumerFactory() {
        return new DefaultKafkaConsumerFactory<>(primeEmployeeConsumerConfig());
    }

我还有另外两种豆子，他们使用这些消费工厂：

@Bean
    public KafkaListenerContainerFactory<ConcurrentMessageListenerContainer<String, String>>
    kafkaEventListenerContainerFactory(ConsumerFactory<String, String> eventConsumerFactory) {
        ConcurrentKafkaListenerContainerFactory<String, String> factory = new ConcurrentKafkaListenerContainerFactory<>();
        factory.setConsumerFactory(eventConsumerFactory);
        factory.setAutoStartup(autoStartupFlag);
        return factory;
    }

    @Bean
    public KafkaListenerContainerFactory<ConcurrentMessageListenerContainer<String, String>>
    kafkaPrimeEmployeeListenerContainerFactory(ConsumerFactory<String, String> primeEmployeeConsumerFactory) {
        ConcurrentKafkaListenerContainerFactory<String, String> factory = new ConcurrentKafkaListenerContainerFactory<>();
        factory.setConsumerFactory(primeEmployeeConsumerFactory);
        factory.setAutoStartup(autoStartupFlag);
        return factory;
    }

我的代码坏了，我出错了 No qualifying bean of type 'org.springframework.kafka.core.ConsumerFactory<java.lang.String, java.lang.String>' available: expected single matching bean but found 2: simpleEventConsumerFactory,simplePrimeEmployeeConsumerFactory 但当我尝试命名qa bean时：

@Bean("eventConsumerFactory")
    @Profile("qa")
    public ConsumerFactory<String, String> simpleEventConsumerFactory() {
        return new DefaultKafkaConsumerFactory<>(eventConsumerConfig());
    }

    @Bean("primeEmployeeConsumerFactory")
    @Profile("qa")
    public ConsumerFactory<String, String> simplePrimeEmployeeConsumerFactory() {
        return new DefaultKafkaConsumerFactory<>(primeEmployeeConsumerConfig());
    }

我会得到一个我不知道的错误 ConsumerFactory<String, String> . 我哪里出错了？
