Spring-kafka example without spring-boot

is it possible to use spring-kafka without using spring-boot.
I have implemeneted producer without spring-boot,
but somehow not able to find consumer alternative i.e. @KafkaListener
Any help on this is useful.

Add an example using JUnit5

It would be great, if you could add an example that uses JUnit5 with @EmbeddedKafka.
Thanks! :)

this is my code:
@test
public void testReceive() throws Exception {
sender.send(BAR_TOPIC, new Bar("bar"));
sender.send(FOO_TOPIC, new Foo("foo"));

receiver.getLatch().await(10000, TimeUnit.MILLISECONDS);
receiver.receiveBar(new Bar());
receiver.receiveFoo(new Foo());

// assertThat(receiver.getLatch().getCount()).isEqualTo(0);
}

I confuse this error.(note: why don't I need to configure zk? why don't I need to configure consumer group.id)

Getting ClassCast Exception : GenericData$Record cannot be cast to org.apache.avro.specific.SpecificRecordBase

While using the given AvroSerializer and Deserializer in Serde with Kafka streams , I am facing ClassCastException
GenericData$Record cannot be cast to org.apache.avro.specific.SpecificRecordBase.

config.put(StreamsConfig.DEFAULT_KEY_SERDE_CLASS_CONFIG, Serdes.serdeFrom(new AvroSerializer()
, new AvroDeserializer(MemberMeasureKey.class)).getClass());
config.put(StreamsConfig.DEFAULT_VALUE_SERDE_CLASS_CONFIG, Serdes.serdeFrom(new AvroSerializer()
, new AvroDeserializer(MemberMeasureValue.class)).getClass());

Please help me on this.
