我在Hibernate 4.2.0 CR1 (最近升级到 Hibernate 4.2.7 final)提供的 JPA 2.0 中有一个多对多的关系，Product如下Colour所示。

Product实体类：

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.
}

Colour实体类。

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.
}

要colour根据prodId提供的与表中的颜色不匹配的颜色prod_colour列表（连接表）从表中获取颜色列表，我正在执行以下条件查询。

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();

此条件查询导致引发以下异常。

org.hibernate.TypeMismatchException：二元逻辑运算符的左侧和右侧不兼容 [java.util.Set(model.Colour.productSet) : model.Product]

但是，以下 JPQL 有效。

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

这个异常的原因是什么。如何使此条件查询起作用？这个相同的条件查询在 EclipseLink 提供的 JPA 中以某种方式起作用。

无论如何，条件查询colour应该根据提供的颜色从表中获取与表中的颜色prodId不匹配的颜色prod_colour列表（它可能是连接查询、子查询或其他任何东西）。

以下条件查询按预期完美运行。

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();

导致以下 SQL 查询。

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=?
    )

尽管它是一个Tuple查询，但可以对实体执行相同的查询。在我的情况下，只有一个Tuple查询就足够了。
