As far as I know, Serializable should be used when deserialization is needed e.g. using dto as return object in APIs. But should I use Serializable for the whole DTO objects or just for the general one?
@Data
@AllArgsConstructor
public class GaDTO implements Serializable {
private static final long serialVersionUID = -xxxx;
private String id;
private GaStatus gaStatus;
private PlaTurn plaTurn;
private PlaDTO pla1;
private PlaDTO pla2;
}
This DTO is the return type of ResponseEntity but there are other DTOs that this GaDTO uses.
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class PlaDTO implements Serializable {
private static final long serialVersionUID = -yyyyyy;
private List<PiDTO> pis;
private PiDTO mainPi;
}
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class PiDTO implements Serializable {
private static final long serialVersionUID = -zzzzzz;
private Integer stos;
}
Should I only use Serializable for GaDTO or do other DTOs need it too?
And why should I use it?
>Solution :
You don’t need to implement Serializable and Deserializable for your DTO because it is already handled by Spring Boot Jackson Package.
