Annotation Interface Entity

@Retention(RUNTIME)
@Target(TYPE)
public @interface Entity

Annotation for mapping entity classes to database tables.

Entities are simple POJOs that map to database rows. Field names are automatically converted to snake_case column names.

Example:

@Entity
public class UserSetting {
    private Long id;           // maps to 'id' column (auto)
    private Long userId;       // maps to 'user_id' column
    private String settingName; // maps to 'setting_name' column
    private String settingValue;
    private Instant createdAt;  // auto-managed
    private Instant updatedAt;  // auto-managed

    // Getters and setters...
}
