I have a problem with updating my database data with Spring rest JPA (PUT Method).
When I do a POST request to insert data, It works perfectly, I have all my data inserted in the right way, however, when I try to update my data with a PUT, the Name is updated event in the database, but not GeometryBasic, I tried to log its value It changes correctly but not in the database, hibernate doesn't persist new values data. I have my classes as following:
Location
@Data
@Entity
@Table(name="sw_locations")
public class Location {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "Location_Generator")
@SequenceGenerator(name="Location_Generator", sequenceName = "Location_Sequence")
private Long id;
@Column(name = "latitude")
private Double latitude;
@Column(name = "longitude")
private Double longitude;
@Column(name = "x")
private Double x;
@Column(name = "y")
private Double y;
@ManyToOne @JoinColumn(name="multi_id") @JsonIgnore
private MultiBasic multi;
public boolean isEmpty() {
boolean hasNoPointCoord = (this.getLatitude() ==null && this.getLongitude() == null);
return hasNoPointCoord;
}
@Override
public String toString() {
return "Location [point="+this.getX()+" : "+this.getY()+" : "+this.getLatitude() +" : "+ this.getLongitude() + "]";
}
}
Multi
public class Multi extends ArrayList<Location>{
//Some methods
}
Geometry
public class Geometry extends ArrayList<Multi>{
//Some Methods
}
GeometryBasic
@Data
@Entity
@Table(name="sw_geometries")
public class GeometryBasic{
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "Geometry_Generator")
@SequenceGenerator(name="Geometry_Generator", sequenceName = "Geometry_Sequence")
private long id;
@OneToMany(mappedBy="geometry",
cascade= CascadeType.ALL, fetch=FetchType.LAZY)
private List<MultiBasic> multies = new ArrayList<MultiBasic>();
//some other methods
}
MultiBasic
@Data
@Entity
@Table(name="sw_multis")
public class MultiBasic{
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "Multi_Generator")
@SequenceGenerator(name="Multi_Generator", sequenceName = "Multi_Sequence")
private long id;
@ManyToOne @JoinColumn(name="geometry_id") @JsonIgnore
private GeometryBasic geometry;
@OneToMany(mappedBy="multi",
cascade= CascadeType.ALL,fetch=FetchType.LAZY)
private List<Location> locations = new ArrayList<Location>();
}
GeometryHelper
public class GeometryHelper {
public static Geometry map(GeometryBasic geom) {
//Check if geometry object is defined and contains multies
if(geom == null || geom.isEmpty())
return null;
Geometry geometry = new Geometry();
//Map nested collections into 2D Array.
geom.getMulties().forEach(m->{
Multi multi = new Multi();
multi.addAll(m.getLocations());
geometry.add(multi);
});
return geometry;
}
public static GeometryBasic mapToBasic (Geometry geom) {
//Check if geometry object is defined and contains multies
if(geom == null)
return null;
GeometryBasic geometry = new GeometryBasic();
List<MultiBasic> multis = new ArrayList<MultiBasic>();
//Iterate over multis to add link to geometry
geom.forEach(m ->{
MultiBasic multi = new MultiBasic();
List<Location> locations = new ArrayList<Location>();
//iterate over locations to add link to Multi
m.forEach( l -> {
l.setMulti(multi);
locations.add(l);
});
multi.setLocations(locations);
multi.setGeometry(geometry);
multis.add(multi);
});
geometry.setMulties(multis);
return geometry;
}
}
Class
@MappedSuperclass
public abstract class AbstractEntityWithNameTitleLocation extends AbstractEntityWithNameTitle {
@Column(name="entity_name")
private String name;
@OneToOne(fetch = FetchType.EAGER, cascade= CascadeType.ALL) @JoinColumn(name = "id_geometry") @JsonIgnore
private GeometryBasic geometryBasic;
public GeometryBasic getGeometryBasic() {
return this.geometryBasic;
}
public void setBasicGeometry(GeometryBasic geometry) {
this.geometryBasic = geometry;
}
@Transient
Geometry geometry;
//Return the transformed object basic geometry
public Geometry getGeometry() {
return GeometryHelper.map(this.geometryBasic);
}
//Return the transformed object basic geometry
public void setGeometry(Geometry geom) {
this.setBasicGeometry(GeometryHelper.mapToBasic(geom));
}
}
