how to consume the json file from kafka using java, parse it using jackson and store it in DB via jdbc
I have written a code to consume the message from kafka, but i want to see an example how the consumed kafka message is converted to java object using jackson and then store it in database for processing the data.
database apache-kafka jackson

Not clear what database you are using... Please don't try to write a consumer yourself to handle this. If you want to simply store JSON messages into a JDBC compatible database, I suggest you use Kafka Connect.

@cricket_007 Thanks for the reply. I am using SAP HANA DB. You are right, we can use kafka connect to directly store the JSON messages in database, but my requirement in my use case is to consume the kafka messsage, convert the JSON string to java objects using jackson and write to DB. Can you please tell me how I can convert the consumed kafka JSON?

Again, doing this yourself and managing offsets and failure scenarios is not going to work out well. Connect does exactly you're requirement, and requires no code on your part, only config files, why not use it?... And if you want to continue down this path, Kafka already provides a JSONDeserializer class for a Consumer property. Have you tried using either it, or a StringDeserializer, then parsing the string in the consumer?

Kafka Connect will do all of this for you. You don't need to be writing any Java code, or converting JSON. Use the kafka-connect-jdbc sink to stream the data to the database, and use the JsonConverter. You can read more about converters in Kafka Connect here.
If you want to process the message beforehand, you can use stream processing options such as Kafka Streams, KSQL, Spark Streaming, etc etc. These can then write to a second Kafka topic. For writing to a database (or anywhere else), simply use Kafka Connect.
