spring boot - How to achieve to get a request, forward it to my application then forward it to the original address?

Question

So at the moment there is a Client that sends the data to Database.

I would like to setup an Nginx proxy between the Client and the Database.

I would like to make the route from Client -> Database to Client -> My spring-boot app -> Database where my spring-boot app make some changes on the data.

For example if I send the following json to Database to store, I catch it with my spring-boot app and I change something. If the client want to save the following data:

{ "name": "Jack", "age": 25 }

I get this request at my spring-boot app and I can change it to:

{ "name": "Jack Sparrow", "age": 250 }

And the database get this and the Database will store the "Jack Sparrow" and "250" and not the "Jack" and "25".

How can I achieve that?

(also I would like if the Client requests the data, my application get the data first and then changes back to its original value. So client asks for the

{ "name": "Jack Sparrow", "age": 250 }

data but it gets back the

{ "name": "Jack", "age": 25 } )

Of course I am not asking about the spring-boot app, but the Nginx configuration.

Thanks in advance.
