I have to implementes Auditing in my aplication.. i inserting this data correctly
but i want to save all atributter from my Entity ,
Exemple, name, epigrafe, .. and olthers.
I implemented the mothod but dosent work, just dont save the atributte..
lets see..
#Entity
#EntityListeners(AuditingEntityListener.class)
#Table(name = "logradouros_historico", schema = "aud")
public class LogradourosHistorico {
#Id
#GeneratedValue
private Long id;
#ManyToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "id_logradouro")
private Logradouros logradouro;
#CreatedBy
private String modificadoPor;
#CreatedDate
#Temporal(TemporalType.TIMESTAMP)
private Date modifiedDate = new Date();
#Enumerated(EnumType.STRING)
private Acoes acao;
#Column(name = "nome")
private String nome; //nome do logradouro
public LogradourosHistorico() {
super();
}
public LogradourosHistorico(Logradouros logradouro, String modificadoPor,
Acoes acao) {
super();
this.logradouro = logradouro;
this.modificadoPor = modificadoPor;
this.acao = acao;
}
//getters and setters
my class entityListner
public class LogradourosEntityListener {
#PostPersist
public void prePersist(Logradouros target) {
perform(target, Acoes.INSERTED);
}
#PreUpdate
public void preUpdate(Logradouros target) {
perform(target, Acoes.UPDATED);
}
#PreRemove
public void preRemove(Logradouros target) {
perform(target, Acoes.DELETED);
}
#Transactional()
private void perform(Logradouros target, Acoes acao) {
target.getNome();
EntityManager entityManager = BeanUtil.getBean(EntityManager.class);
entityManager.persist(new LogradourosHistorico(target, acao));
}
}
my class Logradouros
#Entity
#EntityListeners(LogradourosEntityListener.class)
#Table(name = "logradouros", schema = "glb", uniqueConstraints= #UniqueConstraint(columnNames={"id_entidade", "idLogradouro"}))
public class Logradouros extends Auditable<String> implements Serializable {
private static final long serialVersionUID = 3703309412387185484L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int idLogradouro;
#Column(name = "cep_geral")
private String cepGeral;
#Column(name = "epigrafe")
private String epigrafe;
#NotNull
#Column(name = "nome")
private String nome;
#Column(name = "nome_exibicao")
private String nomeExibicao;
#JoinColumn(name = "id_entidade")
#ManyToOne(/*cascade = CascadeType.ALL*/)
private Entidades entidade;
#NotNull
#JoinColumn(name = "id_municipio")
#ManyToOne(/*cascade = CascadeType.ALL*/)
private Municipios municipio;
// gettrs and settrs
so what i did wrong because i cant get the nome of entity Logradouros
I am having an issue in setting up a many to many relationship in my entities. And I don't understand why
failed; nested exception is org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: cardgame.bean.User.card in cardgame.bean.Card.users
My Entities:
#MappedSuperclass
#Data
public class BaseEntity implements Serializable {
#Id
#Column(name = "id", nullable = false, unique = true)
private String id;
public BaseEntity() {
this.id = UUID.randomUUID().toString();
}
}

private String username;
#Column(name = "uuid", nullable = false)

The users and cards tables have a many-to-many relationship via user_card table:

private User user;
#Id
#ManyToOne
#JoinColumn(name = "card_id", nullable = false)
private Card card;
#Column(name = "cardCount", nullable = false)
private int cardCount;
}
What am i doing incorrect. Please help me
I need to create a criteria query that represents the follow JPQL:
I tryed to specify the class RegraContrato but no success.
SELECT G FROM Grupo G JOIN G.regras R WHERE TYPE(R) = RegraContrato AND R.numeroContrato in(123)
#Entity
#Table(name = "GRUPO_ACESSO")
public class Grupo {
#OneToMany(mappedBy = "grupo",cascade = CascadeType.ALL,fetch = FetchType.EAGER,orphanRemoval = true)
private Set<Regra> regras = Sets.newHashSet();
}
#Entity
#Table(name = "REGRA_ACESSO")
#Inheritance(strategy = InheritanceType.JOINED)
public abstract class Regra {
private static final long serialVersionUID = 5994730323053219858L;
#Id
#SequenceGenerator(name = "REGRA_ID_GENERATOR",sequenceName = "REGRA_SEQUENCE",allocationSize = 1)
#GeneratedValue(strategy = GenerationType.SEQUENCE,generator = "REGRA_ID_GENERATOR")
#Column(name = "ID")
private Long id;
}
#Entity
#PrimaryKeyJoinColumn(name = "ID")
#Table(name = "REGRA_CNPJ")
public class RegraCNPJ extends Regra {
#Column(name = "CNPJ")
private String cnpj;
}
#Entity
#PrimaryKeyJoinColumn(name = "ID")
#Table(name = "REGRA_CONTRATO")
public class RegraContrato extends Regra {
private static final long serialVersionUID = -2840125767126128182L;
#Column(name = "NUMERO_CONTRATO")
private Long numeroContrato;
}
I want to persist an entity(MyEntity) with merge method. This entity have some beans validation.
public class MyEntity extends AbstractEntity {
#Basic(optional = false)
#Column(name = "city", length = 255, nullable = false)
#NotNull
#NotEmpty(message = "{myentity.validation.size.name}")
private String city;
private String number;
#Basic(optional = false)
#Column(name = "zipcode", length = 255, nullable = false)
#NotNull
private String zipcode;
private String phoneNumber;
#Email(message = "{myentity.validation.conform.email}")
#Size(min = 2, max = 100, message = "{myentity.validation.size.email}")
private String email;
private String website;
private String gpsLocation;
#ElementCollection()
#CollectionTable(name = "translation_poi", joinColumns = #JoinColumn(name = "point_id"))
#MapKeyJoinColumn(name = "locale")
#NotEmpty
private Map<Locale, MyEntityI18n> translations = new HashMap<>();
}
#Embeddable
public class MyEntityI18n implements java.io.Serializable {
#Basic(optional = false)
#Column(name = "name", length = 255, nullable = false)
#NotNull
#NotEmpty(message = "{myentity.validation.size.name}")
private String name;
#Column(name = "comment", length = 1200)
private String comment;
#Column(name = "short_description", length = 1200)
private String shortDescription;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
The merge succeeded on an existing entity value but with a new entity the merge failed despite the fact that the following validation succeeded.
private boolean validate(MyEntity poi) {
boolean result = true;
Set<ConstraintViolation<MyEntity>> constraintViolations = validator.validate(poi);
if (constraintViolations.size() > 0) {
result = false;
for (ConstraintViolation<MyEntity> constraints : constraintViolations) {
FacesContext context = FacesContext.getCurrentInstance();
String message = constraints.getPropertyPath() + " " + constraints.getMessage();
context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_WARN, constraints.getMessage(), message));
}
}
return result;
}
Try to add a #Valid to MyEntity.translations property. I think that your validation method hasn't take account the MyEntityI18n.name validation.
About merge fails, Do you have a not-null DB constraint on the MyEntityI18n.name field?
Good luck!
I am currently trying to display information requested via JPA 2.0 (eclipselink). I am using glassfish 3.0.1 and netbeans 6.9.1 as IDE. My persistence entities are created under netbeans option "create entity classes from database". My shcema is designed with workbench mysql, and my server is of course mysql. I really cant figure out what creates this #JoinColumns error.
javax.servlet.ServletException: Exception [EclipseLink-30005] (Eclipse Persistence Services - 2.0.1.v20100213-r6600): org.eclipse.persistence.exceptions.PersistenceUnitLoadingException
Exception Description: An exception was thrown while searching for persistence archives with ClassLoader: WebappClassLoader (delegate=true; repositories=WEB-INF/classes/)

Internal Exception: Exception [EclipseLink-7220] (Eclipse Persistence Services - 2.0.1.v20100213-r6600): org.eclipse.persistence.exceptions.ValidationException
Exception Description: The #JoinColumns on the annotated element [field userInfo] from the entity class [class com.myproject.jpa.UserId] is incomplete. When the source entity class uses a composite primary key, a #JoinColumn must be specified for each join column using the #JoinColumns. Both the name and the referencedColumnName elements must be specified in each such #JoinColumn.
This part randomly swaps from [field userInfo] from the entity class [class com.myproject.jpa.UserId] to [field userIdList] from the entity class [class com.myproject.jpa.Cell]. So both classes probably have the same issue.
Here are my classes:
#Entity
#XmlRootElement

#Column(name = "password", nullable = false, length = 45)
private String password;
#ManyToMany(mappedBy = "userIdList")
private List<Cell> cellList;
#JoinColumn(name = "USER_INFO_id_info", referencedColumnName = "id_info", nullable = false, insertable = false, updatable = false)
#ManyToOne(optional = false)
private UserInfo userInfo;
...
}
#Entity

*The first error was solved, but the [field userIdList] from the entity class [class com.myproject.jpa.Cell]. remains. Ive added the code of my cell table:

Error message describes the problem pretty clearly - UserInfo has a composite key, therefore you need to specify several #JoinColumns, one column for each field of the composite key:
#JoinColumns({
#JoinColumn(...),
#JoinColumn(...)
})
#ManyToOne(optional = false)
private UserInfo userInfo;
From the error message I would try to add the following to your class UserId:
#JoinColumn(name = "USER_INFO_uSERSPORTidsport", referencedColumnName = "uSERSPORTidsport", nullable = false, insertable = false, updatable = false)
#ManyToOne(optional = false)
private UserSport usersport;
