Hello,
I have a question concerning the best practice to handle persisted objects
that have a relation to other objects:
Simple example:
Assume I have an entity class like this:
@XmlRootElement
@Entity
public class Department {
@Id
@GeneratedValue
long id;
@OneToMany
List<Employee> employees;
}
Another one:
@Entity
public class Employee {
@Id
@GeneratedValue
long id;
String name;
}
Now I have persisted some objects into my JPA Database: I have one
Department and two Employees in it.
When I return the Department via Jersey to the Browser, I get this result:
{"employees":[{"id":"8","name":"john"},{"id":"9","name":"jane"}],"id":"10"}
Fine. But very verbose, especialy when my employees have more properties,
or even relations to other entities.
So I would like to limit the output of all my "Sub"-Objects to the ID only.
Something like this:
{"employees":[{"id":"8"},{"id":"9"}],"id":"10"}
What is the best practice to achive this?
Best regards, Florian
