本文整理了Java中org.hibernate.Hibernate.initialize()方法的一些代码示例，展示了Hibernate.initialize()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Hibernate.initialize()方法的具体详情如下：
包路径：org.hibernate.Hibernate
类名称：Hibernate
方法名：initialize

Hibernate.initialize介绍

[英]Force initialization of a proxy or persistent collection.

Note: This only ensures intialization of a proxy object or collection; it is not guaranteed that the elements INSIDE the collection will be initialized/materialized.
[中]强制初始化代理或持久集合。
注意：这仅确保代理对象或集合的初始化；不能保证集合中的元素将被初始化/物化。

代码示例

@Override
public void initialize(Object proxy) throws DataAccessException {
  try {
    Hibernate.initialize(proxy);
  }
  catch (HibernateException ex) {
    throw SessionFactoryUtils.convertHibernateAccessException(ex);
  }
}
