Question

这是通过简单的主类连接到刚刚启动的spring boot项目，它在没有spring-kafka依赖的情况下可以正常工作，但是在添加spring-kafka和spring-kafka-test之后异常炸毁，github here / p>

gradle.build

apply plugin: 'java-library'

repositories {
    jcenter()
 }

dependencies {

     compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: '2.1.0.RELEASE'
     compile group: 'org.springframework.kafka', name: 'spring-kafka', version: '2.0.5.RELEASE'
    testCompile group: 'org.springframework.kafka', name: 'spring-kafka-test', version: '2.0.5.RELEASE'

 }

主班

@SpringBootApplication
public class KafkaMain {

public static void main(String[] args) {
    SpringApplication.run(KafkaMain.class, args);
     }

  }

错误

Answer 1

Apache Kafka的Spring 2.0.x与Spring Boot 2.1.x不兼容。您必须使用Spring-Kafka 2.2.x。仅依靠Spring Boot本身的依赖关系会更好。请参阅https://start.spring.io/了解更多信息，如何正确启动Spring Boot项目。

请不要在没有询问的地方重复您的问题。
