Question

    @Bean
    public ProducerFactory<String, String> producerStringFactory() {
        Map<String, Object> config = new HashMap<>();

        // the server name
        config.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "152.225.215.185:9092");
        // the key type
        config.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
        // the value type
        config.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class);

        return new DefaultKafkaProducerFactory<String, String>(config);

    }

// code
    private static final String TOPIC = "testTopic1";
//code

    @GetMapping("/publish/{message}")
    public String postString(@PathVariable String message) {

        kafkaStringTemplate.send(TOPIC, "This is a message sent to the " + TOPIC + " topic");
        return "Published:  " + message;
