How do I leverage existing KafkaTemplate from Producer config in RetryTopicConfiguration?

[hariraogotit]

Team,

With reference to https://docs.spring.io/spring-kafka/reference/html/#using-retrytopicconfiguration-beans I would like to know how I can leverage existing KafkaTemplate (getSdKafkaTemplate) configured in my KafkaProducer config?

I have the following in MyRetryConfig.java that is annotated with @configuration

@Bean
 public RetryTopicConfiguration myRetryTopic(KafkaTemplate<String, byte[]> kafkaTemplate) {
   return RetryTopicConfigurationBuilder
           .newInstance()
           .exponentialBackoff(3000, 2, 100000)
           .maxAttempts(5)
           .retryTopicSuffix("-asl-nm.retry")
           .dltSuffix("-asl-nm.dlt")
           .create(kafkaTemplate);
 }

In KafkaPublisherConfiguration.java that is also annotated with @configuration has the following

@Bean
  KafkaTemplate<String, byte[]>  getSdKafkaTemplate(
      @Value("${spring.kafka.bootstrap-servers}") String sdServers) {
    return getProducerTemplate(sdServers, bufferMemory, securityProtocol);
  }

I want to make sure that the retry uses the configured producer. So my understanding is in lieu of KafkaTemplate<String, byte[]> kafkaTemplate I need to pass KafkaTemplate<String, byte[]> getSdKafkaTemplate in RetryTopicConfiguration myRetryTopic( to leverage the existing configured KafkaProducer? Kindly let me know if my understanding is correct?

Use a qualifier:

 @Bean(name = "mykafkatemplate")
 KafkaTemplate<String, byte[]>  getSdKafkaTemplate(
      @Value("${spring.kafka.bootstrap-servers}") String sdServers) {   
      return getProducerTemplate(sdServers, bufferMemory, securityProtocol);   
  }   

 @bean
 public RetryTopicConfiguration myRetryTopic(@Qualifier("mykafkatemplate") KafkaTemplate<String, byte[]> kafkaTemplate) {
  ...

Or use the bean name as the parameter name:

public RetryTopicConfiguration myRetryTopic(KafkaTemplate<String, byte[]> mykafkatemplate) {
  ...
