Essentially, tables and entities are not the same. Note: The default name of the table and the entity is camelCase and the PascalCase version of the name of the class. Example- = "users")īy default the name of the table would be user but, as we have supplied the value of the name attribute of the attribute the name of the table in the database would be users. We can change the name of the table by supplying the value of the name attribute of the annotation. By default, the name of the table is the name of the class in cameCase letters.
is a class-level annotation that is used to define the name of the database table. Since we have supplied a value for the name attribute in the annotation the name changed from "User" to "user". By default, the name of the entity would be User. Here, in the above example, we have declared annotation over User class. By default, the name of the entity is the same as the name of the class. This entity has one attribute, name, which is used to define the name of the entity. This annotation is used at the class level to declare a class as a persistence entity. All the classes, interfaces, and annotations work the same way. Note: The name of packages has changed from javax.*. So, the annotation belongs to "jakarta.persistence". From hibernate version 5.5.0 Final the hibernate uses jakarta interfaces. This annotation belongs to the "javax.persistence" package. - Defines data annotation is the most used and required while using hibernate framework.- Defines primary key generation strategy.- Declares entity field as the primary key of the database table.- Defines the properties of table columns.- Defines the properties of the database table.In this post, we are going to see the most commonly used hibernate annotations that we require for the mapping of Java Entity classes to the database tables. We can configure hibernate through Java configuration or XML configuration and the mapping details can be provided through XML or Java Annotations. Mapping details - to map the entity classes to database tables.
#HIBERNATE ANNOTATIONS IN DETAIL DRIVER#
Database connection details - database credentials like driver class, username, password, and connection URL, to connect to the database.Hibernate Configuration - to configure caching strategies, SQL statement logging in the console, etc.To put the hibernate into work we need to provide three things: Hibernate is an open-source Java ORM tool that is used between the Java application and the JDBC that connects to the database.
