Table mapping

By default, an entity class is mapped to a table with the same name as the class. However, there are cases when you need to modify this default name for one of the following reasons:

• You need to use a custom name for a neater database design.
• You have to map it to an existing table in a legacy database.
• Your entity name is a SQL reserved keyword, for example, User. You are forced to modify the table name, otherwise you will end up with a runtime error.

The @Table annotation is used to customize the table name as in the following example:

@Entity 
@Table(name = "movies") 
public class Movie { 
    ... 
}
