非代理Hibernate对象的优雅方式 [英] Elegant way of unproxy Hibernate objects

问题描述

我正在用Jax-RS和GSON创建一个Web服务。现在，GSON无法转换HibernateProxy对象，我有一些问题。我有一个API，以便我可以加载和延迟加载。当我想要重载时，我使用Hibernate.initialize（...）。但是，这似乎并不能保证一个对象是没有问题的？

I am creating a web service with Jax-RS and GSON. Now, GSON can't convert HibernateProxy objects and I have some questions. I am having an API so that I can eager load and lazy load. When I want to eagerload I use Hibernate.initialize(...). However this does not seem to guarantee that a object is unproxied?

那么，何时，何时以及如何取消对某个对象的处理？如何处理这个问题，当对象也可能有其他的对象也需要取消处理？

So where, when and how would you unproxy an object? And how do you deal with this when the object also may have releations to other objects that also need to be unproxied?

推荐答案

是一个示例代码：

Here is a sample code:

public <P> List<P> unproxy(Collection<P> objects) {
    Session session = sessionFactory.getCurrentSession();
    List<P> result = new ArrayList<P>();
    for (P t : objects) {
        Object unproxied = ((SessionImplementor)session).getPersistenceContext().unproxy(t);
        result.add((P) unproxied);
    }
    return result;
}
