Hibernate is a framework and has a layered architecture. In this chapter, we will discuss the Hibernate architecture and its underlying components. Hibernate persists Java object in the database but Hibernate needs to know about Database details. Metadata of objects like which table to be used, ...
对于某一个特定的持久化上下文,Hibernate保证持久化标识与Java标识(其值代表对象在内存中的位置)等价。 ◆脱管(detached) 实例曾经与某个持久化上下文发生过关联,不过那个上下文被关闭了, 或者这个实例是被序列化(serialize)到这个进程来的。 它拥有持久化标识,并且在数据库中可能存在一个对应的行。 对于脱管状态的...
The “minimal” architecture has the application manage its own JDBC connections and provide those connections to Hibernate; additionally the application manages transactions for itself. This approach uses a minimal subset of Hibernate APIs. The “comprehensive” architecture abstracts the application away ...

Following is a detailed view of the Hibernate Application Architecture with its important core classes.Hibernate uses various existing Java APIs, like JDBC, Java Transaction API(JTA), and Java Naming and Directory Interface (JNDI). JDBC provides a rudimentary level of abstraction of functionality ...

1.三层架构分层三层架构(3-tier architecture) 通常意义上的三层架构就是将整个业务应用划分为:界面层(User Interface layer)、业务逻辑层(Business Logic Layer)、数据访问层(Data access layer)。区分层…
COLA 是 Clean Object-oriented and Layered Architecture的缩写,代表“整洁面向对象分层架构”,是来自阿里技术专家的DDD开源项目。COLA是一套用于帮助开发人员快速实践DDD落地的项目架构。目前COLA已经发展到COLA 4.0。 在COLA架构中,比如我们想创建一个User,一套完整的调用链大概如下图所示: 1. 前端发起... ...

AMDD建议使用两种类型的模型:需求(requirements)和架构(architecture)。需求模型有域模型(参考图3)、用法模型(例如用户故事/用例,参考图4)以及UI模型(例如原型和流程图,分别参考图5和图6)等。 图3:域模型 图4:用法模型 图5:原型形式的UI模型 图6:流程图形式的UI模型 ...
