You can dramatically simplify the code for a DTO by using https://projectlombok.org[Project Lombok], which provides an `@Value` annotation (not to be confused with Spring's `@Value` annotation shown in the earlier interface examples).
If you use Project Lombok's `@Value` annotation, the sample DTO shown earlier would become the following:

[source, java]
[source,java]
----
@Value
class NamesOnly {
String firstname, lastname;
}
----

Fields are `private final` by default, and the class exposes a constructor that takes all fields and automatically gets `equals(…)` and `hashCode()` methods implemented.
