[Enhancement]: Refactor StatementEntity.java for Lombok Sample Usage #460
Description
What
Refactor StatementEntity.java in the sample server to use Lombok annotations like @DaTa, @Getter, @Setter, @NoArgsConstructor, and @AllArgsConstructor. This will replace boilerplate code such as explicit getters/setters/constructors, providing a modern, concise example.
Why
Having a sample that fully supports Lombok will make testing and demonstrating annotation-based Java entity patterns easier, and help ensure that the BerryCloud/xapi-java project has relevant developer resources for integration and onboarding.
Notes
Please review any existing usage patterns of StatementEntity and ensure runtime and compilation compatibility. If appropriate, add a short note in the README about using Lombok in entity samples for future contributors.
