以容器方式保存钝化是EntityBeans

EntityBean 主要用来保存一个Entity的对象,同时操作PassivateEntity对保存的实体进行钝化或者激活.
也可以说是对EntityBean的包装,当对一个EntityBean包装时,便可以对此Entity进行精确的version控制
package org.jboss.seam.contexts;
import static org.jboss.seam.contexts.PassivatedEntity.passivateEntity;
/**

注意：PersistenceContext未确切了解,是否是每个钝化对象对应一个,是否是跟线程Contexts有关.
应该是跟线程Contexts关联,因为可能有多个数据源
package org.jboss.seam.contexts;
import java.io.Serializable;
import javax.persistence.EntityManager;
import org.hibernate.Session;
import org.jboss.seam.Component;

继承Model,以Key-name Value-class保存Entity,统一保存在ApplicationContext中
Entity主要是保存@Entity的生命周期方法以及Entity的名称.

Seam中含有三种组建
1.Model 2.Entity 3.Component 2继承1 3继承1
Seam中的内部对象不是为Mode就是Entity
用Model可以包装@Name标记的类Class
同时Component继承Model,对Class进行一些复杂的处理
package org.jboss.seam;
import org.jboss.seam.contexts.Contexts;
public class Model
{
private Class<?> beanClass;
