Spring Boot applications deal a lot with DTOs, responses, and immutable objects. Java 17βs record feature makes our lives easier:
public class User {
private String name;
private String email;
public User(String name, String email) {
this.name = name;
this.email = email;
}
public String getName() { return name; }
public String getEmail() { return email; }
}
After (Using Java 17 record π)
public record User(String name, String email) {}
β
No more boilerplate.
β
Automatic toString(), equals(), and hashCode().
β
Immutable by default.
When to use records? Perfect for DTOs and API responses, but avoid them for JPA entities!
