java - Hibernate findByexample 问题

Question

我有两个表用户和地址表

它们在 HBM 中的关系是

<!-- bi-directional one-to-one association to Address -->
    <one-to-one
        name="user"
        class="address"
        outer-join="auto"
    />

因此，当我在 User Pojo 中设置 Address Pojo 并为 User Pojo 调用 findByExample 时。

它忽略地址 Pojo

Answer 1

reference manual说:

Version properties, identifiers and associations are ignored.

但它也说:

You can even use examples to place criteria upon associated objects.

List results = session.createCriteria(Cat.class)
    .add( Example.create(cat) )
    .createCriteria("mate")
        .add( Example.create( cat.getMate() ) )
    .list();
