1. What is Hibernate Simply said hibernate is a ORM framework, where ORM stands for Object (Java) - Relational (DB) mapping, Hibernate is developed based on JDBC api, which has greatly reduced the code work when dealing with Databse. 2. Environment set up and Code example. Four steps ar...
Hibernate是java提供的一个ORM solution, 是一个open source persistent framework。Hibernate在java object和table之间以及object data type和db data type之间提供映射。 Hibernate的好处:1. 使用XML文件而不是java code来map java class和database table;2. 提供简单的API来从DB中直接获取或存储Java object;3. 使用...
http://www.w3cschool.cn/hibernate/p7a91ie4.html 本课你将学习Hibernate的架构。 下面图表描述了hibernate的高级架构: 上面的图表显示,Hibernate被用于数据库和配置数据,为应用程序提供持久化服务(持久化对象)。 为使用Hibernate,需要创建代表数据库中的表的Java类,进而用数据库的列映射成类的实例变量。然后,Hiberna...
Hibernate is an open source object relational mapping (ORM) tool that provides a framework to map object-oriented domain models to relational databases for web applications. Object relational mapping is based on the containerization of objects and the abstraction that provides that capacity. Abstraction...
Hibernate ORM is a powerful object/relational mapping solution for Java, and makes it easy to develop persistence logic for applications, libraries, and frameworks. Hibernate implements JPA, the standard API for object/relational persistence in Java, but also offers an extensive set of features and...
hibernate能自动处理RuntimeException,如果是其他的，则要自己进行处理的Hibernate异常及错误处理——汇总一、super.getHibernateTemplate()execute(HibernateCallback)错误信息：The method execute(HibernateCallback<T>) in the type HibernateTemplate is not applicable for the arguments (new HibernateCallback...
数据库DSL编程的另一个主要卖点是变化适应性强,数据库表结构在开发过程中通常会频繁发生变化,传统的非DSL编程,字段名只是一个字符串,如果字段名或者类型改变之后,查询语句没有相应修改,编译不会出错,也容易被开发人员忽略,是bug的一个主要来源。DSL编程里面,字段被逆向工程为一个java类的属性,数据库结构改变之后,作...

For the purposes of logging, Hibernate Validator uses the JBoss Logging API, an abstraction layer which supports several logging solutions such (e.g. log4j or the logging framework provided by the JDK) as implementation. Just add a supported logging library to the classpath (e.g. log4j-<...
