java – Kafka获取错误在引导服务器中给出了无可解析的引导程序URL

我很确定bootstrap.servers是正确的. Maven中有什么冲突或Kafka有什么问题吗?

在此之前它成功地运作了.我添加了一些Maven或Spark然后出了点问题..

谁能知道如何解决它?

这是java中的kafka代码

Properties props = new Properties();
        props.put("bootstrap.servers", "x.xx.xxx.xxx:9092");
        props.put("metadata.broker.list", "x.xx.xxx.xxx:9091, x.xx.xxx.xxx:9092, x.xx.xxx.xxx:9093");

        props.put("producer.type", "async");
        props.put("batch.size", "500");
        props.put("compression.codec", "1");
        props.put("compression.topic", topicName);
        props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
        props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");

            org.apache.kafka.clients.producer.Producer<String, String> producer = new KafkaProducer<String, String>(
                    props);

获取错误在引导服务器中没有给出可解析的引导程序URL,

最佳答案
不推荐使用“metadata.broker.list”,而是使用“bootstrap.servers”.从代码中删除“metadata.broker.list”配置应该可以解决问题.请在difference between bootstrap.servers and metadata.broker.list找到更多详情
