Listing 15-1 shows you the modified model, the Document class. It uses three annotations. The @Id that will help
to identify the object saved, the @DBRef that will add a reference to another collection (remember that Mongo uses
collections for saving objects), and finally the @Document annotation that identifies a domain object to be persisted
into a collection.
Listing 15-2 shows you another domain model, the Type class.
Listing 15-2. Type.java
package com.apress.isf.java.model;
import org.springframework.data.annotation.Id;
@org.springframework.data.mongodb.core.mapping.Document(collection="types")
public class Type {
@Id
private String typeId;
private String name;
private String desc;
private String extension;
//Constructors Omitted
public String getTypeId() {
return typeId;
}
