我在尝试用spring启动应用程序运行junit时遇到了一个奇怪的问题。它在kafka服务器启动时引发致命错误异常。
这是我的junit
import org.junit.ClassRule;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.kafka.test.rule.KafkaEmbedded;
import org.springframework.test.annotation.DirtiesContext;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest(classes=SpringKafkaSenderTest.class)
@DirtiesContext
public class SpringKafkaSenderTest {
@ClassRule
public static KafkaEmbedded embeddedKafka = new KafkaEmbedded(1, true, "foo");
@Autowired
private KafkaTemplate<String, String> template;
@Test
public void test() throws InterruptedException {
template.send("foo", "bar");
Thread.sleep(10_000);
}
}
这是我的应用程序测试.yaml
spring.profiles: test
spring:
profiles:
include: kafka
kafka:

它在junit上运行时抛出异常,以下是我的异常日志部分:

有人能帮我解决这个问题吗?

按热度按时间zpgglvta1#
什么版本的引导?什么版本的SpringKafka?什么版本的 Spring Kafka考试?什么版本的Kafkajar?
看起来类路径上有不匹配的kafka jar。
spring-kafka
以及spring-kafka-test
必须是同一版本,并且kafka-clients
以及kafka_2.11
必须是相同的版本。看起来像是
kafka_2.11
为0.10.0.2和kafka-clients
是另一个版本。
