Java 如何使用hibernate连接两个表

我想使用HQL或Criterial连接两个表

桌子是

• 购物车表（购物车ID、bookid、customeremailid、数量）
• 书桌（书号、书名、书价、书量）

我的sql查询是这样的

select count(c.cartId) as cartId,b.bookName as bookName,c.customeremailid as customeremailid,sum(b.bookPrice)as c.price,c.quantity from Book b,Cart c where  c.customeremailid='"+customeremailid+"' and b.bookId=c.bookid

这将给出

cartId

的计数和

bookPrice

我正在将此结果存储到

列表中

以下是

购物车POJO

变量

private int bookid,cartId;
    private String customeremailid,bookName,bookDescription,image;
    private int quantity;
    private long price;

HQL查询：

String sql="select count(c.cartId) as cartId,b.bookName as bookName,c.customeremailid as customeremailid,sum(b.bookPrice)as price,c.quantity from Book b,Cart c where  c.customeremailid='"+customeremailid+"' and b.bookId=c.bookid";
             Query q=s.createSQLQuery(sql);
             Cartlist=q.setResultTransformer(Transformers.aliasToBean(Cart.class)).list();


             for(Cart c :Cartlist)
             {
                 System.out.println("in cart : "+c.getCartId());
                 System.out.println("in cart : "+c.getPrice());
             }

我不知道在Hibernate里怎么做

恳请建议

感谢使用hibernate标准加入，示例代码如下：

List cats = sess.createCriteria(Cat.class)
    .createAlias("kittens", "kt")
    .createAlias("mate", "mt")
    .add( Restrictions.eqProperty("kt.name", "mt.name") )
    .list();
