In fact this is just a Warning (an addict). which can even be disabled with @Suppresswarnings("")
import ...
.
.
.
@SuppressWarnings("serial")
public class AplicacaoEntity implements Serializable {
private Long id;
private String descricao;
.
.
.
or by adding the line in the class :
private Static final long serialVersionUID = 1L; as the example below:
import ...
.
.
.
public class AplicacaoEntity implements Serializable {
private static final long serialVersionUID = 1L;
private Long id;
private String descricao;
.
.
.
Important:
if you are mounting a JSF project, remember that every bean with scope Session is required to implement serializable;
I hope I’ve helped;
