Spring for Apache Kafka® 101: Sending Messages to Apache Kafka with Spring Boot (Hands On)

cnfl.io/spring... | Learn by adding a producer class based on a KafkaTemplate to your code. You'll use the java-faker library to mock data from a book and push it to an Apache Kafka® topic in Confluent Cloud, adding the Flux library to push one message per second. On Confluent Cloud, you'll create a topic for your mock book data, so that when you run your application you can view your messages in the Confluent Cloud UI.

I think there is a disconnect with the previous video in which a ProducerFactory was explained. In the current video I don't think the factory is mentioned/used at all. Maybe I am mistaken.

In case your spring application isn't able to find the broker since it is by default pointing to the bootstrap-server localhost:9092, you can override the bootstrap-sever to point to the server your confluent cloud provides you with by pasting the properties file you get from confluent cloud and then
replacing the property spring.kafka.properties.bootstrap.servers=
with
spring.kafka.bootstrap-servers=

Very usefull video. I'm enjoying this playlist a lot. Thanks for the explanations full of details.

[@Indrajeetviper]

is there a github repo that we can refer to?

[@saisreenath5189]

Where did he use kafkatemplate, i can see 1 usage of the template property? can someone help

[@sohrabsheykhmohammadi1909]

thanks, can we have multiple key and value serdes for one producer ?
what we can do when we need multiple producer with different key and value serdes in one spring boot application?

[@seonwookim5391]

How about using json strings?

[@francksgenlecroyant]

@@seonwookim5391 json string will make you serialize and deserialize your data manually, it's time consuming, you should use the spring json serde

[@rydmerlin]

It think it’s too convoluted with Flux

Your series of tutorials doesn't work if you follow every steps. T. On the previous tutorial before this your configure KafkaTemplate with here you made it which won't run. Also your java configuration you put localhost:9092 for bootstrap server but in the application.properties you need to put the one generated by the client environment in your confluent cluster.
Trying Confluent Cloud as we are considering it for our kafka application. But your tutorials sucks.

That faker example is not working .. could Confluent not afford to hire a better programmer ?
can't believe this clown is the only support we have for learning how to use Confluent

These "problems" are simple fixable, but as for me, it's much simpler to watch his videos instead of Hindus. He tells in 4 minutes video the same information they have in 30 minutes video.
