sessionfactory

We should create a SessionFactory object only once when the application starts .

我们应该仅仅在应用程序启动的时候创建SessionFactory对象。

A SessionFactory is resource intensive and has a relatively high initialization cost .

SessionFactory是密集型资源，而且它的初始化成本较高，从另一方面讲，Session使用了有限的资源，而且强加一些初始化成本。

To simplify working with the JCR , the module adds the SessionFactory interface

为了简化与JCR的工作，模块增加了SessionFactory接口

A second-level cache also can be configured to be shared among all sessions of the SessionFactory , including across a cluster .

还可以将二级缓存配置为在SessionFactory的所有会话之间共享（包括在集群之间共享）。

The default implementation of SessionFactory is JcrSessionFactory which requires a repository to work against , and the credentials .

SessionFactory的缺省实现是JcrSessionFactory，它要求一个进行工作的仓库和证书。

SessionFactory hides the authentication details inside the implementation so that once configured , sessions with the same credentials can be easily retrieved .

SessionFactory隐藏了实现内部的认证细节，因此一旦配置完成，使用同一证书的会话可以很容易的被检索出来。

In the Spring framework , resources such as a JDBC DataSource or a Hibernate SessionFactory can be realized as beans in an application context .

在Spring框架中，像JDBCDataSource或HibernateSessionFactory这样的资源，在应用程序上下文中可以用bean实现。

Other than the abstract property , the bean definition simply points out that I want an instance of GenericDaoHibernateImpl and that it needs a reference to a SessionFactory .

除了抽象特性之外，该bean定义只指出我想要GenericDaoHibernateImpl的实例以及该实例需要对SessionFactory的引用。

With the data source and session factory set up , the next step is to wire in the DAO , in this case CustomerDAOImpl , to use the SessionFactory .

数据源和会话工厂设置好之后，下一步就是在DAO中连接，在CustomerDAOImpl示例中，要使用SessionFactory。

All I have to do now is wire up my domain objects , which in this case , because they 'll rely on Hibernate , require a SessionFactory type to work .

现在我需要做的就是连接我的域对象，在本示例中，因为它们依赖于Hibernate，需要一个SessionFactory类型进行工作。

Thus far , I 've created a builder class that properly configures a ShardedSessionFactory , which really is just an implementation of Hibernate 's ubiquitous SessionFactory type .

到目前为止，我已经创建一个可以合理配置ShardedSessionFactory的生成器类，其实就是实现Hibernate无处不在的SessionFactory类型。
