休眠條件示例查詢

Question

我有一個Hibernate示例查詢的問題。我如何使用Hibernate示例查詢連接查詢。這是我想要做的;

Cat cat = new Cat(); 
cat.setFood(myFoodObject); // Food is another entity that has reference to Cat class. 
List results = session.createCriteria(Cat.class) 
.add(Example.create(cat)) 
.list(); 

my food class;

public class Food { 
..... 
@OneToMany(cascade = CascadeType.ALL,mappedBy = "food", fetch = FetchType.EAGER) 
private List<Cat> catList; 
} 

我的貓類;

public class Cat{ 
..... 
@JoinColumn(name = "food", referencedColumnName = "id") 
@ManyToOne(cascade = CascadeType.ALL,fetch = FetchType.EAGER) 
private Food food; 
}

The documentation for Example queries說：

版本屬性，標識符和協會被忽略。
