Hibernate supports Query cache and provide statistics about query and database status. 6) Provides Query Statistics and Database Status 5) Simplifies Complex Joinįetching data from multiple tables is easy in hibernate framework. So there is no need to create tables in the database manually. Hibernate framework provides the facility to create the tables of the database automatically. Before Hibernate, if database is changed for the project, we need to change the SQL query as well that leads to the maintenance problem. So you don't need to write database specific queries. It generates the database independent queries. HQL (Hibernate Query Language) is the object-oriented version of SQL. There are two types of cache in hibernate framework first level cache and second level cache. The performance of hibernate framework is fast because cache is internally used in hibernate framework. Hibernate framework is open source under the LGPL license and lightweight. 2) Add project information and configuration in pom.xml file. Advantages of Hibernate Frameworkįollowing are the advantages of hibernate framework: 1) Open Source and Lightweight Hibernate Example using Annotation in Eclipse 1) Create the Maven Project To create the maven project left click on File Menu - New - Maven Project. Database connection details - database credentials. To put the hibernate into work we need to provide three things: Hibernate Configuration - to configure caching strategies, SQL statement logging in the console, etc. XML Since Java adopted annotations, I’ve heard a lot of discussion around whether to prefer annotations over external configuration files (often XML) and vice versa. Hibernate is an open-source Java ORM tool that is used between the Java application and the JDBC that connects to the database. The javax.persistence package contains the JPA classes and interfaces. Annotations vs Configuration in Hibernate Annotations vs. Java Persistence API (JPA) is a Java specification that provides certain functionality and standard to ORM tools. The ORM tool internally uses the JDBC API to interact with the database. It is a programming technique that maps the object to the data stored in the database. Hibernate implements the specifications of JPA (Java Persistence API) for data persistence.Īn ORM tool simplifies the data creation, data manipulation and data access. It is an open source, lightweight, ORM (Object Relational Mapping) tool. Hibernate is a Java framework that simplifies the development of Java application to interact with the database. It was started in 2001 by Gavin King as an alternative to EJB2 style entity bean. This hibernate tutorial provides in-depth concepts of Hibernate Framework with simplified examples.
