Question

下面的Java代码抛出异常，如底部所示。环境：Tomcat，Java8

KafkaConsumer <String, Map<ConfidentialityLevel, CommonCoreEvent>> consumer;
Properties props = new Properties();
String topic = "common-core-document-changes";
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "kafka-dev-0.europe.intranet:9092");
props.put("schema.registry.url", "http://kafka-dev-0.europe.intranet:8081");
props.put(ConsumerConfig.CLIENT_ID_CONFIG, "dbnlxclasid1");
props.put(ConsumerConfig.GROUP_ID_CONFIG, UUID.randomUUID().toString());
props.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest");
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName());
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, KafkaAvroDeserializer.class.getName());
props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG,true);
consumer = new KafkaConsumer<String, Map<ConfidentialityLevel, CommonCoreEvent>>;

使用的JAR文件：
