Java spring Kafka与嵌入式Kafka的集成测试

我有一个spring引导应用程序，它让一个使用者从一个集群中的主题消费，并在不同集群中生成另一个主题

现在我正试图使用spring embedded Kafka编写集成测试用例，但有一个问题，

KafkaTemplate无法注册。具有该名称的bean已在类路径资源中定义

消费者类别

@Service
public class KafkaConsumerService {

@Autowired
private KafkaProducerService kafkaProducerService;

@KafkaListener(topics = "${kafka.producer.topic}")
public void professor(List<Professor> pro) {
    pro.forEach(kafkaProducerService::produce);
    
   }

}

@Service
public class KafkaProducerService {

@Value("${kafka.producer.topic}")
private String topic;

@Autowired
private KafkaTemplate<String, Object> kafkaTemplate;

public void produce(Professor pro) {
    kafkaTemplate.send(topic,"professor",pro);
  }

 }

@EnableKafka
@SpringBootTest(classes = {KafkaProducerConfigTest.class})
@RunWith(SpringRunner.class)
public class KafkaProducerServiceTest {

@Autowired
private KafkaConsumerService kafkaConsumerService;

@Test
public void testReceive() throws Exception {
     kafkaConsumerService.professor(Arrays.asList(new Professor()));
     
     //How to check messages is sent to kafka?
}

 }

测试类

@Service
public class KafkaConsumerService {

@Autowired
private KafkaProducerService kafkaProducerService;

@KafkaListener(topics = "${kafka.producer.topic}")
public void professor(List<Professor> pro) {
    pro.forEach(kafkaProducerService::produce);
    
   }

}

@Service
public class KafkaProducerService {

@Value("${kafka.producer.topic}")
private String topic;

@Autowired
private KafkaTemplate<String, Object> kafkaTemplate;

public void produce(Professor pro) {
    kafkaTemplate.send(topic,"professor",pro);
  }

 }

@EnableKafka
@SpringBootTest(classes = {KafkaProducerConfigTest.class})
@RunWith(SpringRunner.class)
public class KafkaProducerServiceTest {

@Autowired
private KafkaConsumerService kafkaConsumerService;

@Test
public void testReceive() throws Exception {
     kafkaConsumerService.professor(Arrays.asList(new Professor()));
     
     //How to check messages is sent to kafka?
}

 }

错误

 The bean 'kafkaTemplate', defined in com.kafka.configuration.KafkaProducerConfigTest, could not be registered. 
 A bean with that name has already been defined in class path resource [com/kafka/configuration/KafkaProducerConfig.class] and overriding is disabled.
 Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

还有人能帮我验证发送到嵌入式Kafka服务器的消息吗

注意我收到了一些不推荐的警告

KafkameBedded类型已弃用

不推荐使用KafkameBedded类型的getPartitionsPerTopic（）方法

不推荐使用KafkaTestUtils类型的方法producerProps（KafkameBedded）

启动2.1

默认情况下已禁用Bean重写，以防止意外重写Bean。如果依赖重写，则需要将

spring.main.allow bean definition overriding

设置为

true

关于反对意见；有关

@EmbeddedKafka

，请参阅javadocs。它被

EmbeddedKafkaBroker

替换，谢谢您的回复，先生，我这样做了，但是现在不同的问题

字段kafkamebed在com.kafka.configuration.KafkaProducerConfigTest中需要一个类型为“org.springframework.kafka.test.rule.kafkamebedded”的bean，但找不到它。

；现在是嵌入式卡夫卡布洛克<代码>@Autowired public Embedded Kafkabroker broker。
