原理：利用Hibernate3提供的PostLoadEventListener在loadHibernate實體類的時候觸發PostLoadEvent事件，編寫一個自定義的事件監聽器，注入依賴的Spring Bean對象.此方法來自于ThoughtWorks的 PerrynFowler

package?hibernate;

public?class?Article?{
????private?User?user;

????public?User?getUser()?{
????????return?user;
????}

????public?void?setUser(User?user)?{
????????this.user?=?user;

????
}

package?hibernate;

import?java.util.List;

public?interface?UserManager?{
????public?void?save(User?user);
????public?void?delete(User?user);
????public?List?getArticleByUser(User?user);
}

在web層可以這樣用
user.save();
user.delete();

最有用的地方是下面所描述的
user.getArticles(),實際調用的是userManager.getArticleByUser(User user);
只需要在Article端配置many-to-one到User,而不需要User端的one-to-many到Article,利用這個單向的關聯來查詢得到列表
1.是可以實現延遲加載的效果,并且不用open session in view
2.可以分頁,分頁這個方式也比較特別,由javaeye的Prentice網友提出來的(一種傳遞分頁參數的方法),使用ServletFilter或Interceptor在WEB層截獲分頁的參數，
封裝成一個對象，然后保存在threadlocal中,Service進行查詢的時候可以按需從threadlocal中獲得分頁參數。
