Question

我在使用maven运行Spring集成测试时得到了OOME。 Surefire插件获得了大量内存，这应该不是问题。但我仍然像这样得到OOME：

我试过没有运气的@DirtyContext 我该如何解决这个问题？可能是根本原因？

删除使用嵌入式Kafka进行测试的例外

<dependency>
    <groupId>org.springframework.kafka</groupId>
    <artifactId>spring-kafka-test</artifactId>
    <scope>test</scope>
</dependency>

@Component
public class EmbeddedKafkaComponent extends KafkaEmbedded {

    @Autowired
    public EmbeddedKafkaComponent(@Value("${spring.kafka.topic}") String topic) {
        super(1, true, topic);
    }

    @PostConstruct
    public void postConstruct() throws Exception {
        before();
    }

    @PreDestroy
    public void preDestroy() {
        after();
    }
}

@Configuration
@Profile("test")
public class ConsumerAppTestConfig {

    @Autowired
    private EmbeddedKafkaComponent embeddedKafka;

    @Bean
    public Map<String, Object> consumerConfig() {
        return KafkaTestUtils.consumerProps(groupId, "true", embeddedKafka);
    }

停止容器时Apache Kafka错误。 OOME
