I'm using Spring 3.1.1.RELEASE, Hibernate 4.1.0.Final, JUnit 4.8, and JPA 2.0 (hibernate-jpa-2.0-api). I'm trying to write a query and search based on fields of member fields. What I mean is I have this entity …
@GenericGenerator(name = "uuid-strategy", strategy = "uuid.hex")
@Entity
@Table(name = "cb_organization", uniqueConstraints = {@UniqueConstraint(columnNames={"organization_id"})})
public class Organization implements Serializable
{
@Id
@NotNull
@GeneratedValue(generator = "uuid-strategy")
@Column(name = "id")
/* the database id of the Organization */
private String id;
@ManyToOne
@JoinColumn(name = "state_id", nullable = true, updatable = false)
/* the State for the organization */
private State state;
@ManyToOne
@JoinColumn(name = "country_id", nullable = false, updatable = false)
/* The country the Organization is in */
private Country country;
@ManyToOne(optional = false)
@JoinColumn(name = "organization_type_id", nullable = false, updatable = false)
/* The type of the Organization */
private OrganizationType organizationType;
Notice the members "organizationType," "state," and "country," which are all objects. I wish to build a query based on their id fields. This code
@Override
public List<Organization> findByOrgTypesCountryAndState(Set<String> organizationTypes,
String countryId,
String stateId)
{
CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<Organization> criteria = builder.createQuery(Organization.class);
Root<Organization> org = criteria.from(Organization.class);
criteria.select(org).where(builder.and(org.get("organizationType.id").in(organizationTypes),
builder.equal(org.get("state.id"), stateId),
builder.equal(org.get("country.id"), countryId)));
return entityManager.createQuery(criteria).getResultList();
}
is throwing the exception below. How do I heal the pain?
