I'm new to JPA and trying to do relations between two tables like this:
This is the main class object XParserLinks:
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Basic(optional = false)
#Column(name = "link_id")
private Integer linkId;
#OneToMany(mappedBy = "xParserLink", targetEntity = XLinksMedia.class, cascade = CascadeType.ALL)
private List<XLinksMedia> fotos;
...
This is the object class XLinksMedia
public class XLinksMedia implements Serializable {
private static final long serialVersionUID = 1L;
#EmbeddedId
protected XLinksMediaPK xLinksMediaPK;
#ManyToOne #JoinColumn(name = "link_id")
private XParserLinks xParserLink;
and XLinksMediaPK
#Embeddable
public class XLinksMediaPK implements Serializable {
#Basic(optional = false)
#Column(name = "link_id", insertable = false, updatable = false)
private int linkId;
#Basic(optional = false)
#Column(name = "image")
private String image;
Are these relations correct? Because when I want to add new XLinksMedia objects in fotos list, I get LinkId = 0, but I know that LinkId is not 0, I know that LinkId variable have a value.
Here's how I try to set fotos variable in XParseLinks class (preke: is XParseLinks object witch have his primary key LinkId):
XLinksMedia foto = new XLinksMedia();
foto.setXLinksMediaPK(new XLinksMediaPK());
foto.setxParserLink(preke);
foto.getXLinksMediaPK().setImage(e.attr("src"));
preke.getFotos().add(foto);
Even I don't know what is your expectation, When I test your coding, it is OK. I just put some of the OverLoad Constructor for easy data initialization in your classes. But, you use GenerationType.IDENTITY, that's why I set auto increate column for link_id of XParserLinks. The main of the following coding is same as yours.
Your point Here's how I try to set fotos variable in XParseLinks class (preke: is XParseLinks object witch have his primary key LinkId):. Check Test.java
XParserLinks.java

fotos = new ArrayList<XLinksMedia>();

this.something = something;

public XParserLinks(String something) {
this.something = something;
fotos = new ArrayList<XLinksMedia>();
}

fotos.add(media);
}
}

public class Test {
public static void main(String[] args) {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("JPA");
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
XParserLinks xParserLink = new XParserLinks("something");
XLinksMediaPK pk1 = new XLinksMediaPK(0, "image_1");
XLinksMediaPK pk2 = new XLinksMediaPK(0, "image_2");
XLinksMediaPK pk3 = new XLinksMediaPK(0, "image_3");
xParserLink.add(new XLinksMedia(pk1, xParserLink));
xParserLink.add(new XLinksMedia(pk2, xParserLink));

I have this error with JPA when I update a Person with my repository appUserRepository.save():

I've looked at posts on stackoverflow regarding this error but can't find any solutions. I also tried the cascadeType.ALL. Just bellow you can see in Class 'WeightRecordController' the post method 'saveWeight'. The 'personRepository.save(personToUpdate);' create error when it's called.

In fact the problem concerned entities mapping. Instead of #ElementCollection i use now #OneToMany for the user's weights list and it's ok.
I have imported a screenshoot of my Entities after this change. Thanks for help !
Just bellow my new entity Person :
#Entity

when doing the persistence in the entities the information is saved automatically, but in the table third table it does not insert the primary keys.
I have added CascadeType.ALL on Episodio as it is the owner of this relation.
Following code may help you. I have tested with spring data jpa.

class service

You should also add the linkage #OneToMany in Pacientes:
public class Pacientes implements Serializable {
...
#OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "pessoa")
#PrimaryKeyJoinColumn
private List<PessoasEnderecos> pessoasEnderecos = new ArrayList<>();
Update:
and your JSON should be something like this:
{
"nomeResponsavel": "abc",
"pessoasEnderecos": [
{
"bloco": "sdds",
"cep": "sdasdsad",
"numero": "sdasdsa"
}
]
}
I am trying to dynamicaly create a Specification for my Spring-data-jpa project
Here is my specification for the moment:
public class DemandsSpecs implements Specification<SvDem> {
private static final Logger LOG = LogManager.getLogger();
private final DemandsCritera critera;
private final List<Predicate> predicateList;
public DemandsSpecs(final DemandsCritera critera) {
this.critera = critera;
this.predicateList = new ArrayList<>();
}
#Override
public Predicate toPredicate(final Root<SvDem> root,
final CriteriaQuery<?> query,
final CriteriaBuilder cb) {
this.predicateList.add(cb.between(root.get(SvDem_.hdCreation), critera.getBegin(), critera.getEnd()));
if (critera.getSoc() != null) {
LOG.debug("socId {}", critera.getSoc());
this.predicateList.add(cb.equal(root.get(SvDem_.socId), critera.getSoc()));
}
if (critera.getManagementAct() != null) {
LOG.debug("actgesId {}", critera.getManagementAct());
this.predicateList.add(cb.equal(root.get(SvDem_.actgesId), critera.getManagementAct()));
}
if (critera.getStatus() != null) {
LOG.debug("statutId {}", critera.getStatus());
this.predicateList.add(cb.equal(root.get(SvDem_.statutId), critera.getStatus()));
}
if (!StringUtils.isBlank(critera.getId())) {
LOG.debug("id {}", critera.getId());
this.predicateList.add(cb.like(root.get(SvDem_.id), '%' + critera.getId() + '%'));
}
return query.where(cb.and(predicateList.toArray(new Predicate[predicateList.size()])))
.orderBy(cb.desc(root.get("hdCreation")))
.getRestriction();
}
}
The DemandsCritera also have a String property metadata.
public class DemandsCritera implements Serializable {
private static final Long serialVersionUID = 1L;
private Date begin;
private Date end;
private RfActges managementAct;
private String metadata;
private RfStatut status;
private RfSoc soc;
private String id;
/* getters and setters */
}
SvDem has a property svMetaCollection which is a Collection<SvMeta>.
#Entity
#Table(name = "sv_dem")
public class SvDem implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Basic(optional = false)
private String id;
#Basic(optional = false)
#Column(name = "HD_CREATION")
#Temporal(TemporalType.TIMESTAMP)
private Date hdCreation;
#Lob
private String user;
#OneToMany(cascade = CascadeType.ALL, mappedBy = "svDem")
#JsonManagedReference
private Collection<SvMeta> svMetaCollection;
#JoinColumn(name = "ACTGES_ID", referencedColumnName = "ID")
#ManyToOne(optional = false)
private RfActges actgesId;
#JoinColumn(name = "STATUT_ID", referencedColumnName = "ID")
#ManyToOne(optional = false)
private RfStatut statutId;
#JoinColumn(name = "SOC_ID", referencedColumnName = "ID")
#ManyToOne(optional = false)
private RfSoc socId;
/* getters, setters and other irrelevant properties */
}
The SvMeta object has a String property value
#Entity
#Table(name = "sv_meta")
public class SvMeta implements Serializable {
private static final long serialVersionUID = 1L;
#EmbeddedId
protected SvMetaPK svMetaPK;
#Basic(optional = false)
#Lob
private String value;
#JoinColumn(name = "META_ID", referencedColumnName = "ID", insertable = false, updatable = false)
#ManyToOne(optional = false)
private RfMeta rfMeta;
#JoinColumn(name = "DEM_ID", referencedColumnName = "ID", insertable = false, updatable = false)
#ManyToOne(optional = false)
#JsonBackReference
private SvDem svDem;
}
I want to return all the SvDem where any of its SvMeta has a value equals to the DemandsCritera.metadata.
How can I achieve that?
I just needed to add this to my toPredicate method of DemandsSpecs:
if (!StringUtils.isBlank(critera.getMetadata())) {
LOG.debug("metadata {}", critera.getMetadata());
Join<SvDem, SvMeta> metas = root.join(SvDem_.svMetaCollection);
this.predicateList.add(cb.equal(metas.get(SvMeta_.value), critera.getMetadata()));
}
I have three entities and i have one parent class. Tarifa entity has "pvp" column, so I don't want it in "servicio" entity.
