Hibernate的QBC查询语句问题

有三张表分别关系如下：
Member表（会员表，属性：id主键，等等）
Product表（产品表，属性：id主键，等等）
MemberFavoriteProduct表：（会员关注产品表）

create table MemberFavoriteProduct(

    favorite_members int references Member(id) not null,

    favorite_products int references Products(id) not null,

    primary key(favorite_members, favorite_products)

)

实体：
Member实体：

	private Set<Product> favoriteProducts = new HashSet<Product>();

        .........

	@ManyToMany(fetch = FetchType.LAZY)

	@JoinTable(name = "MemberFavoriteProduct", joinColumns = @JoinColumn(name = "favorite_members"), inverseJoinColumns = @JoinColumn(name = "favorite_products"))

	public Set<Product> getFavoriteProducts() {

		return this.favoriteProducts;

	}



	public void setFavoriteProducts(Set<Product> favoriteProducts) {

		this.favoriteProducts = favoriteProducts;

	}

Product实体：

	private Set<Member> favoriteMembers = new HashSet<Member>();

        ..........

	@ManyToMany(mappedBy = "favoriteProducts", fetch = FetchType.LAZY)

	public Set<Member> getFavoriteMembers() {

		return this.favoriteMembers;

	}



	public void setFavoriteMembers(Set<Member> favoriteMembers) {

		this.favoriteMembers = favoriteMembers;

	}

根据以上实体映射，所以没有建立MemberFavoriteProduct实体

需求：想根据会员去查它关注的有哪些产品，dao方法：

		Criteria criteria = this.getSession().createCriteria(Product.class);

		criteria.createAlias("favoriteMembers","x", JoinType.INNER_JOIN);

		criteria.add(Restrictions.eq("x.favoriteMembers", member));//member为参数对象

		.........

x为别名，但是打印出的语句是

select count(*) as y0_ from Product this_ inner join MemberFavoriteProduct favoriteme3_ on this_.id=favoriteme3_.favorite_products inner join Member x1_ on favoriteme3_.favorite_members=x1_.id where favoriteme3_.favorite_members.id = ?

问题：它把member对象给取别名为x了，不是MemberFavoriteProduct对象取名为x，如何才能得到MemberFavoriteProduct的别名，或者怎么去设置它的别名，求出结果？？（还是用QBC） 求大神支招，感激不尽！！
