Spring Table and Entity

tags : Spring Boot

The @Entity and @Table annotations are used to define and map Java classes to database tables. Here’s the difference between the @Entity and @Table annotations:

1. @Entity Annotation:

   • The @Entity annotation is used to mark a Java class as a persistent entity, indicating that it should be mapped to a database table.
   • It is typically placed on the class level of a Java entity class.
   • The entity class represents a table in the database, and each instance of the class represents a row in that table.
   • By default, the entity name is derived from the class name, but it can be customized using the name attribute of the @Entity annotation.

   Example:

   @Entity
   public class Student {
      // fields, getters, and setters
   }

2. @Table Annotation:

   • The @Table annotation is used to specify the details of the database table to which an entity class is mapped.
   • It is typically placed on the class level of a Java entity class, alongside the @Entity annotation.
   • The @Table annotation allows you to customize the table name, schema, and other properties associated with the table.

   Example:

   @Entity
   @Table(name = "student")
   public class Student {
      // fields, getters, and setters
   }

By using both annotations together, you can define the entity class and specify the table details, such as the table name, schema, and any other properties associated with the table.
