composite key issue
Hello, I tried your solution of embeddedId but i still get errors :(
table declaration: CREATE COLUMNFAMILY medimage.tag ( id_dicom uuid, nom text, codifie boolean, PRIMARY KEY (id_dicom, nom) );
those are my classes:
public class IdTag{
@Column private UUID id_dicom;
@Column private String nom;
public IdTag() { super(); // TODO Auto-generated constructor stub }
public IdTag(UUID id_dicom, String nom) { super(); this.id_dicom = id_dicom; this.nom = nom; }
public UUID getId_dicom() { return id_dicom; }
public void setId_dicom(UUID id_dicom) { this.id_dicom = id_dicom; }
public String getNom() { return nom; }
public void setNom(String nom) { this.nom = nom; } }
@Entity(name = "tag") public class Tag implements Serializable{
private static final long serialVersionUID = 3L;
@EmbeddedId private IdTag id;
@Column private Boolean codifie;
public Tag (UUID id_dicom, String nom, Boolean codifie){ this.id = new IdTag(id_dicom, nom); this.codifie = codifie; }
public Tag(IdTag id, Boolean codifie) { super(); this.id = id; this.codifie = codifie; }
public IdTag getId() { return id; }
public void setId(IdTag id) { this.id = id; }
public Boolean getCodifie() { return codifie; }
public void setCodifie(Boolean codifie) { this.codifie = codifie; } }
public class TagRepository {
private Persistence persistence;
public List<Tag> find(String nom) { return persistence.selectBuilder(Tag.class).eq("nom", nom).execute(); }
{ this.persistence = CassandraManager.INSTANCE.getPersistence(); }
public void save(Tag tag) { persistence.insert(tag); }
public Tag findByDicomId(UUID uuid) { return persistence.findByKey(uuid, Tag.class); }
public List<Tag> findAll(){ return persistence.findAll(Tag.class); } }
When I try to fetch elements by name ("nom") or simply all elements i get a arraylist with the right amount of elements but all null.
Could you help me?
