Spring 启动嵌入式kafka抛出错误BeanCreationException

Question

我有一个具有以下配置的 kafka 属性的测试用例：

@ExtendWith(SpringExtension.class)
@SpringBootTest(classes = {Application.class})
@ActiveProfiles("test")
@EnableConfigurationProperties
@EmbeddedKafka(controlledShutdown = true, topics = {"topic1", "topic2", "topic3"})
class Name {}

这是我在运行上面的测试用例时得到的构建错误：

Application run failed 
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'embeddedKafka': Invocation of init method failed; nested exception is java.lang.NoSuchFieldError: DEFAULT_SASL_ENABLED_MECHANISMS
Caused by: java.lang.NoSuchFieldError: DEFAULT_SASL_ENABLED_MECHANISMS

    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1790)
    ... 72 common frames omitted

这是具有 spring kafka 和 kafka-client 依赖项的 POM 文件，这可能会导致错误：

            <groupId>org.springframework.kafka</groupId>
            <artifactId>spring-kafka</artifactId>

Answer 1

spring-Kafka 版本与 Apache Kafka 客户端不兼容 3.0。您还需要 2.8 和 Spring 启动 2.6.

另一方面，即使您使用更新的代理，您也不需要更新的客户端。虽然这个故事是关于嵌入式测试的，所以我完全怀疑你是否需要担心任何客户端，除非它是从 Spring 到 Apache Kafka 的传递......
