The problem I'm encountering is that I have a superclass and 2 subclasses that I'm trying to query. I thought that querying the superclass would return objects of that class and all subclasses, but it does so WITHOUT any of their sub attributes. Currently, my models are set up in a single table:
@Entity
@Table(name="person")
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(discriminatorType=DiscriminatorType.STRING, name="TYPE")
public class Person
private String name;
@Entity
@DiscriminatorValue(value="EMPLOYEE")
public class Employee extends Person
private int salary;
@Entity
@DiscriminatorValue(value="CLIENT")
public class Client extends Person
private int age;
When I query the Person table using findAll(), I was expecting to return all objects with their class specific properties, although they only have their superclass properties. Ex:
javascript
// I'm looking for something like so
[
name: "Tony", // A simple Person
name: "Tom", salary: 10, // An Employee
name: "Todd", age: 20 // A Client
]
// What I'm getting
[
name: "Tony", // A simple Person
name: "Tom", // An Employee
name: "Todd" // A Client
]
