How to limit a collection in an Object's property in hibernate?

Question

I have two entities: item, and bid, each item have many bids for it, so bid is a collection property of item.

in the page that show an item, I just want to show the firs

Answer 1

you can use criteria's setFirstResult() and setMaxResult(). or this post would be helpful for your question

example:

sessionFactory.getCurrentSession().createQuery("your query here").setFirstResult(0).setMaxResult(10);

this will generate 10 rows of data from database

you have use annotation driven. simply add the annotation Size to your bid object

    @OneToMany( mappedBy = "object", cascade = CascadeType.ALL)
    @Size(min=1, max=10)
    private Set    bid;
