【问题描述】：

我正在尝试为 debezium 集成设置一个集成测试环境（按照example 中的说明进行操作），但测试容器（默认图像：confluentinc/cp-kafka:5.2.1）没有启动，但会抛出一个例外。

我正在使用下面提到的代码来创建一个 KafkaContainer bean

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

                kafkaContainer.start();
           
        

        return kafkaContainer;
    

它抛出以下异常。

***************************
APPLICATION FAILED TO START
***************************

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

【问题讨论】：

更多细节，好吗？什么样的异常？另外，即使你发布了一个链接，最好添加一个代码sn-p

@VitalyChura 我添加了代码 sn-ps 和 strack 跟踪日志。

【参考方案1】：

在 maven 依赖项中使用了旧版本的 org.testcontainers，它可以工作。谢谢！

我打算建议尝试一个更新的，但是好的，不管用什么）
