java.lang.Object

java.lang.Record

com.privatechain.examples.spring.BlockchainRestController.TransactionRequest

Record Components:

receiverAddress - destination blockchain address (non-null, non-blank)

amount - transfer amount (≥ 0)

currency - ISO-4217 currency code (non-null, non-blank)

Enclosing class:

BlockchainRestController

public static record BlockchainRestController.TransactionRequest(String receiverAddress, BigDecimal amount, String currency)
extends Record

Immutable request body for BlockchainRestController.submitTransaction(com.privatechain.examples.spring.BlockchainRestController.TransactionRequest).

Uses a Java 16+ record so Spring MVC can deserialize it via Jackson without any additional configuration — records expose their components as public accessor methods, which Jackson uses for both serialization and deserialization when the constructor is annotated with JsonCreator.
