问题
I have a many-to-many relationship in JPA 2.0 provided by Hibernate 4.2.0 CR1 (recently upgraded to Hibernate 4.2.7 final) between Product and Colour as follows.
The Product entity class:
public class Product implements Serializable
{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "prod_id")
private Long prodId;
@JoinTable(name = "prod_colour", joinColumns = {
@JoinColumn(name = "prod_id", referencedColumnName = "prod_id")}, inverseJoinColumns = {
@JoinColumn(name = "colour_id", referencedColumnName = "colour_id")})
@ManyToMany(fetch = FetchType.EAGER)
private Set<Colour> colourSet;
//Setters and getters.
}
The Colour entity class.
public class Colour implements Serializable
{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "colour_id")
private Long colourId;
@ManyToMany(mappedBy = "colourSet", fetch = FetchType.EAGER)
private Set<Product> productSet;
//Setters and getters.
}
To fetch a list of colours from the colour table based on prodId supplied which does not match the colours in the prod_colour table (join table), I'm executing the following criteria query.
CriteriaBuilder criteriaBuilder=entityManager.getCriteriaBuilder();
CriteriaQuery<Colour>criteriaQuery=criteriaBuilder.createQuery(Colour.class);
Metamodel metamodel = entityManager.getMetamodel();
EntityType<Colour> entityType = metamodel.entity(Colour.class);
Root<Colour> root = criteriaQuery.from(entityType);
criteriaQuery.select(root);
Subquery<Long>subquery=criteriaQuery.subquery(Long.class);
Root<Product> subRoot = subquery.from(Product.class);
subquery.select(root.get(Colour_.colourId));
Predicate paramPredicate = criteriaBuilder.equal(subRoot.get(Product_.prodId), prodId);
Predicate correlatePredicate = criteriaBuilder.equal(root.get(Colour_.productSet), subRoot);
subquery.where(criteriaBuilder.and(paramPredicate, correlatePredicate));
criteriaQuery.where(criteriaBuilder.in(root.get(Colour_.colourId)).value(subquery).not());
criteriaQuery.orderBy(criteriaBuilder.desc(root.get(Colour_.colourId)));
TypedQuery<Colour> typedQuery = entityManager.createQuery(criteriaQuery);
List<Colour>list=typedQuery.getResultList();
This criteria query causes the following exception to be thrown.
org.hibernate.TypeMismatchException: left and right hand sides of a binary logic operator were incompatibile [java.util.Set(model.Colour.productSet) : model.Product]
The following JPQL however works.
FROM Colour colour
WHERE colour.colourId
NOT IN(
SELECT colours.colourId
FROM Product product
INNER JOIN product.colourSet colours
WHERE product.prodId=:id)
ORDER BY colour.colourId DESC
What is the cause of this exception. How to make this criteria query work? This same criteria query somehow works in JPA provided by EclipseLink.

Anyway, the criteria query should fetch a list of colours from the colour table based on prodId supplied which does not match the colours in the prod_colour table (It could be a join query, a subquery or anything else).
回答1:
The following criteria query works perfectly as expected.
CriteriaBuilder criteriaBuilder=entityManager.getCriteriaBuilder();
CriteriaQuery<Tuple>criteriaQuery=criteriaBuilder.createTupleQuery();
Metamodel metamodel = entityManager.getMetamodel();
EntityType<Colour> entityType = metamodel.entity(Colour.class);
Root<Colour> root = criteriaQuery.from(entityType);
criteriaQuery.multiselect(root.get(Colour_.colourId), root.get(Colour_.colourName), root.get(Colour_.colourHex));
Subquery<Long>subquery=criteriaQuery.subquery(Long.class);
Root<Colour> subRoot = subquery.from(Colour.class);
subquery.select(subRoot.get(Colour_.colourId));
SetJoin<Colour, Product> join = subRoot.join(Colour_.productSet, JoinType.INNER);
ParameterExpression<Long> parameterExpression=criteriaBuilder.parameter(Long.class);
criteriaQuery.where(criteriaBuilder.in(root.get(Colour_.colourId)).value(subquery).not());
subquery.where(criteriaBuilder.equal(join.get(Product_.prodId), parameterExpression));
TypedQuery<Tuple> typedQuery = entityManager.createQuery(criteriaQuery);
List<Tuple> list = typedQuery.setParameter(parameterExpression, 1L).getResultList();
Resulting in the following SQL query.
select
colour0_.colour_id as col_0_0_,
colour0_.colour_name as col_1_0_,
colour0_.colour_hex as col_2_0_
from
social_networking.colour colour0_
where
colour0_.colour_id not in (
select
colour1_.colour_id
from
social_networking.colour colour1_
inner join
prod_colour productset2_
on colour1_.colour_id=productset2_.colour_id
inner join
social_networking.product product3_
on productset2_.prod_id=product3_.prod_id
where
product3_.prod_id=?
)
Although it is a Tuple query, one may execute the same query on an entity. In my case, only a Tuple query is sufficient.
