Creating a model

In this project, we will create a REST API to see the list of user details where we can get a username, email ID, and contact number. So let's create a model of a user where the class name is UserModel.kt.

Here is the code of the model class:

@Entity@Table(name="user_jpa")@EntityListeners(AuditingEntityListener::class)data class UserModel(    @Id    @GeneratedValue(strategy = GenerationType.IDENTITY)    @Column(name = "id")    var id: Long = 0,    @NotBlank    @Column(name = "name")    var name: String ?= null,    @NotBlank    @Column(name = "email")    var email: String ?= null,    @NotBlank    @Column(name = "contact_number")    var contact_number: String ?= null)

Here, our UserModel class has the following fields:

• id: Primary key with auto increment
• name
