Hibernate 可以通过一个JMX标准服务来管理。 在这个发行版本中,我们提供了一个MBean接口的实现,即 org.hibernate.jmx.HibernateService。 想要看如何在JBoss应用服务器上将Hibernate部署为一个JMX服务的例子,您可以参考JBoss用户指南。 我们现在说一下在Jboss应用服务器上,使用JMX来部署Hibernate的好处: Session管理: Hiber...
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, ...
Short-lived, single threaded objects containing persistent state and business function. These can be ordinary JavaBeans/POJOs. They are associated with exactly one org.hibernate.Session. Once the org.hibernate.Session is closed, they will be detached and free to use in any application layer (for ...
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 common to relational databases, allowing almost any database with a JDBC driver to be supported by ...
A single-threaded, short-lived object representing a conversation between the application and the persistent store. Wraps a JDBC java.sql.Connection. Factory for org.hibernate.Transaction. Maintains a first level cache of persistent the application’s persistent objects and collections; this cache is ...
使用 NHibernate 和 EF 等 ORM,域类和关系表之间的映射可以用映射类或基于 XML 的配置来表示。结果,您的域类被隐式映射 - 不需要 DTO。有些情况确实需要 DTO,在这种情况下,DTO 和域类之间的映射应该由存储库实现封装。这是您可以调用 AutoMapper 的地方。
传统J2EE或Spring+Hibernate等事务性编程模型只关心数据,这些数据对象除了简单setter/getter方法外,没有任何业务方法,被比喻成失血模型 贫血模型 充血模型 让过去被肢解被黑crack的业务模型回归正常 "世界观" 接触到需求第一步就是考虑领域模型,而不是将其切割成数据和行为,然后数据用数据库实现,行为使用服务实现,最后...
The architecture of JNDI in Java In the architecture, we notice the different directories associated with JNDI, which consists of an API and an interface known as Service Provider Interface(SPI). In this diagram, we notice the JNDI architecture, which is connected to the Java application. The ...
The ORM module provides integration layers for popular object-relational mapping APIs, including JPA, JDO, Hibernate, and iBatis. The OXM module provides an abstraction layer that supports Object/XML mapping implementations for JAXB, Castor, XMLBeans, JiBX and XStream. The Java Messaging Service JMS...
J2EE提供JCA(Java Connector Architecture)规范来标准化对EIS(Enterprise Information System)的访问。这个规范被分为几个不同的部分: SPI(Service provider interfaces)是连接器提供者(connector provider)必须实现的接口。 这些接口组成了一个能被部署在J2EE应用服务器上的资源适配器(resource adapter)。 在这种情况下,由...
