springBoot整合kafka出错_org.apache.kafka.clients.consumer.consumergroupmet-优快云博客

本文链接：https://blog.youkuaiyun.com/INT_MIN/article/details/128106129

博客介绍了在使用Spring-Kafka时遇到的版本冲突问题，特别是与kafka-clients的版本不匹配导致的错误。解决方案是确保两个库的版本与SpringBoot版本相一致。在示例中，将spring-kafka更新到2.8.8版，而kafka-clients更新到3.0.0版以解决冲突。然而，更新后出现了`java.lang.IllegalStateException: Failed to load ApplicationContext`等错误，这可能是由于依赖注入问题或类找不到导致的。

情景复现：spring-kafka版本对应的kafka-clients版本冲突

        <dependency>
            <groupId>org.springframework.kafka</groupId>
            <artifactId>spring-kafka</artifactId>
            <version>2.8.8</version>
        </dependency>
        <dependency>
            <groupId>org.apache.kafka</groupId>
            <artifactId>kafka-clients</artifactId>
            <version>2.0.1</version>
            <scope>test</scope>
        </dependency>

解决方法：将两者版本与springBoot相对应，版本对应关系可以参考如下文章：(28条消息) spring-kafka、kafka-client 和springboot的版本对应关系_sky～hello的博客-优快云博客_spring-kafka版本例如：

         <dependency>
            <groupId>org.springframework.kafka</groupId>
            <artifactId>spring-kafka</artifactId>
            <version>2.8.8</version>
        </dependency>
        <dependency>
            <groupId>org.apache.kafka</groupId>
            <artifactId>kafka-clients</artifactId>
            <version>3.0.0</version>
            <scope>test</scope>
        </dependency>
