如何在标准顺序中使用映射列by

Question

Criteria criteria = session.createCriteria(Items.class); 
criteria.add(Restrictions.eq("itemId", 1003)); 
criteria.addOrder(Order.desc("category.categoryName")); 

这里Category是ManyToOne映射。 谢谢！

Answer 1

Criteria criteria = session.createCriteria(Items.class) 
    .add(Restrictions.eq("itemId", 1003)) 
    .createAlias("category", "category") 
    .addOrder(Order.desc("category.categoryName"));
