Using Java Records with Spring Boot 3

Java Records, introduced as a standard feature in JDK 16, offer a concise way to define immutable data classes. With Spring Boot 3 (requiring Java 17+), Records can be used in three key areas: binding application configuration properties via @ConfigurationProperties, handling HTTP request/response payloads with Jackson (which supports Records since 2.12), and applying Bean Validation constraints directly on record components. Code examples show how a verbose immutable class with equals/hashCode/toString boilerplate reduces to a single-line record declaration, and how records integrate with Spring MVC controllers and @Validated configuration classes.
