java - Spring Boot找不到嵌入式KafkaBroker Bean

我正在为Kafka编写集成测试。为此，我正在使用Spring的EmbeddedKafka。这是我的课：

@Component
@EmbeddedKafka(
    partitions = 1,
    topics = {"Topic},
    brokerProperties = {"listeners=PLAINTEXT://localhost:9091", "port=9091"})
public class KafkaConsumerTestUtils {
  @Autowired private EmbeddedKafkaBroker embeddedKafka;
  ....
}

我正在用@SpringBootTest注释的类中自动装配此utils类。这是我得到的错误：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.kafka.test.EmbeddedKafkaBroker' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoMatchingBeanFound(DefaultListableBeanFactory.java:1646)
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1205)
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:1166)
    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:593)
    ... 66 more

奇怪的是，当我在任何测试类中自动连接EmbeddedKafkaBroker时，都会创建它并且测试运行正常。

有人可以帮我弄这个吗？

最佳答案

不能完全确定为什么，但是您似乎没有按照预期的方式使用它。

@EmbeddedKafka是可以在运行基于Spring Kafka的测试的测试类上指定的注释。

文档状态：

The typical usage of this annotation is like:
 @RunWith(SpringRunner.class)
 @EmbeddedKafka
 public class MyKafkaTests {}
