我正在使用kafka Confluent schema registry中的SpecificAvroSerde读取模式,但是我遇到了以下错误:
org.apache.kafka.common.errors.InvalidConfigurationException: Unauthorized; error code: 401
[TestStreamProcess-StreamThread-1] ERROR org.apache.kafka.streams.KafkaStreams - stream-client [TestStreamProcess] Encountered the following exception during processing and the registered exception handler opted to SHUTDOWN_CLIENT. The streams client is going to shut down now.
org.apache.kafka.streams.errors.StreamsException: Deserialization exception handler is set to fail upon a deserialization error. If you would rather have the streaming pipeline continue after a deserialization error, please set the default.deserialization.exception.handler appropriately.

我正在从config.properties文件中加载所需的配置,以成功连接到模式注册表:
schema.registry.url=<confluent Schema Registry URL>
basic.auth.credentials.source=USER_INFO
schema.registry.basic.auth.user.info=<Schema Registry API Key>:<schema Registry Secret Key>
serdesConfig已经设置好并且需要的导入已经完成:
import static io.confluent.kafka.serializers.AbstractKafkaSchemaSerDeConfig.*;
public static SpecificAvroSerde<TestStream> getTestStreamSerde(Properties props) {
SpecificAvroSerde<TestStream> testStreamSerde= new SpecificAvroSerde<>();
testStreamSerde.configure(getSerdeProps(props), false);
return testStreamSerde;
}
protected static Map<String, String> getSerdeProps(Properties props) {
final HashMap<String, String> map = new HashMap<>();
final String schemaUrlConfig = props.getProperty(SCHEMA_REGISTRY_URL_CONFIG);
map.put(SCHEMA_REGISTRY_URL_CONFIG, ofNullable(schemaUrlConfig).orElse(""));
}
final KStream<String, TestStream> testStream = builder.stream("input-topic",
Consumed.with(String(), getTestStreamSerde(props.getProperties())));
在pom.xml中已经加载了Schema Registry artifact:
<plugin>
<groupId>io.confluent</groupId>
<artifactId>kafka-schema-registry-maven-plugin</artifactId>
<version>${confluent.version}</version>
</plugin>
你能帮我确定我的配置缺少了什么吗?
