在使用Spring Cloud Stream中解析Avro格式消息时,可能会遇到反序列化异常。为了解决此问题,可以使用以下方法:
@SpringBootApplication
@EnableBinding(Processor.class)
@EnableSchemaRegistryClient
public class MyApp {
public static void main(String[] args) {
SpringApplication.run(MyApp.class, args);
}
}
@Component
public class MyMessageHandler {
@StreamListener(Processor.INPUT)
public void handleMessage(MyMessage message) {
// Do something
}
@ServiceActivator(inputChannel = "errorChannel")
public void handle(KafkaException exception) {
// Handle exception
}
}
@AvroMessageType("MyMessage.avsc")
public class MyMessage {
@AvroSchema("int")
private Integer value;
public Integer getValue() {
return value;
}
public void setValue(Integer value) {
this.value = value;
}
}
org.springframework.cloud
spring-cloud-stream-binder-kafka-streams
3.1.0
io.confluent
kafka-avro-serializer
5.5.1
com.fasterxml.jackson.core
jackson-databind
2.11.4
io.confluent
kafka-schema-registry-client
6.1.0
org.springframework.kafka
spring-kafka
2.7.1
通过以上步骤,就可以实现Avro反序列化异常处理与Spring Cloud Stream相结合的功能了。
