卡夫卡测试容器未运行

问题描述

我正在尝试为debezium集成设置集成测试环境（按照此example中的说明进行操作），但是测试容器（默认图像：confluentinc / cp-kafka：5.2.1）没有启动，但是引发异常。

我正在使用下面提到的代码来创建KafkaContainer bean

    @Bean
    public KafkaContainer kafkaContainer() {
        if (kafkaContainer == null) {
            kafkaContainer = new KafkaContainer()
                    .withNetwork(network())
                    .withExternalZookeeper("172.17.0.2:2181");

                kafkaContainer.start();
           }
        }

        return kafkaContainer;
    }

它引发以下异常。

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.testcontainers.containers.KafkaContainer.getBootstrapServers(KafkaContainer.java:91)

The following method did not exist:

    org/testcontainers/containers/KafkaContainer.getHost()Ljava/lang/String;

The method's class,org.testcontainers.containers.KafkaContainer,is available from the following locations:

    jar:file:/home/shubham/.m2/repository/org/testcontainers/kafka/1.14.3/kafka-1.14.3.jar!/org/testcontainers/containers/KafkaContainer.class

The class hierarchy was loaded from the following locations:

    org.testcontainers.containers.KafkaContainer: file:/home/shubham/.m2/repository/org/testcontainers/kafka/1.14.3/kafka-1.14.3.jar
    org.testcontainers.containers.GenericContainer: file:/home/shubham/.m2/repository/org/testcontainers/testcontainers/1.12.5/testcontainers-1.12.5.jar
    org.testcontainers.containers.FailureDetectingExternalResource: file:/home/shubham/.m2/repository/org/testcontainers/testcontainers/1.12.5/testcontainers-1.12.5.jar


Action:

Correct the classpath of your application so that it contains a single,compatible version of org.testcontainers.containers.KafkaContainer

解决方法

在maven依赖项中使用了org.testcontainers的较旧版本，并且可以正常工作。谢谢！
