Question

我在Java中使用融合的Avro生产器，但是在运行它时出现问题。我添加了所有必需的jar。没有任何线索我错过了什么？

Exception in thread "main" java.lang.NoSuchFieldError: PASSWORD
    at io.confluent.kafka.serializers.AbstractKafkaAvroSerDeConfig.baseConfigDef(AbstractKafkaAvroSerDeConfig.java:92)
    at io.confluent.kafka.serializers.KafkaAvroSerializerConfig.<clinit>(KafkaAvroSerializerConfig.java:28)
    at io.confluent.kafka.serializers.KafkaAvroSerializer.configure(KafkaAvroSerializer.java:48)
    at org.apache.kafka.common.serialization.ExtendedSerializer$Wrapper.configure(ExtendedSerializer.java:60)
    at org.apache.kafka.clients.producer.KafkaProducer.<init>(KafkaProducer.java:341)
    at org.apache.kafka.clients.producer.KafkaProducer.<init>(KafkaProducer.java:302)

我尝试了以下配置。

Properties prop = new Properties();
        prop.put("bootstrap.servers", "localhost:9092");
        prop.put("schema.registry.url", "http://localhost:8081");
        //prop.put("basic.auth.user.info", "");
        prop.put("ssl.keystore.type",null);
        prop.put("acks", "all");
        prop.put("retries", "0");
        prop.put("key.serializer", "io.confluent.kafka.serializers.KafkaAvroSerializer");
        prop.put("value.serializer", "io.confluent.kafka.serializers.KafkaAvroSerializer");
        prop.put("group.id", "test");

这些是我使用它的依赖项。所有具有最新版本的jar。

我在混合版本时看到此错误。这些也不是最新版本，因为MvnReposistory不会缓存实际的Confluent存储库。

您只需要这个

    <dependency>
        <groupId>io.confluent</groupId>
        <artifactId>kafka-avro-serializer</artifactId>
        <version>5.2.1</version>
    </dependency>
