Java 是否可以使用kafka控制台生成器通过事务客户端发送消息？

我想使用kafka console producer cli工具使用事务客户端向主题发送消息。我认为我的配置对此是正确的，但当我运行cli工具时，会出现以下异常：

java.lang.IllegalStateException: Cannot perform a 'send' before completing a call to initTransactions when transactions are enabled.

因此，kafka控制台生成器（我相信它实例化了kafka.tools.ConsoleProducer类）似乎不是在调用initTransactions，就是在调用完成之前发送

我是否可以使用事务将kafka console producer cli发送到主题

以下是我用来运行kafka console产品用户的命令行：

export KAFKA_OPTS="-Djava.security.auth.login.config=/tmp/kafka/jaas.conf";echo "test message" | kafka-console-producer --broker-list wildthing-2.gce.cloudera.com:9092 --topic ${topic}  --producer.config /tmp/kafka/client.properties

我使用的是卡夫卡2.2.1版。 以下是结果输出的生产者配置：

@本，你说得对。cli kafka控制台生成器调用scala类kafka.tools.ConsoleProducer。据我所知，只有新的Java生产者和消费者支持一次语义。有关更多详细信息，请参阅文档。因此，为了直接回答您的问题-不，我认为您无法让现成的cli kafka控制台生产者以事务方式发送消息。但是，您可以使用新的Java producer API编写自己的producer，并从shell脚本调用它。

您可以使用kafkacat，我认为它现在支持EOS
