I try to POST the object
{
"id": "SOME_ID",
"foo": "http://localhost:8080/api/subclass-of-foo/OBJECT_ID"
}
The Foo Class is abstract. Information about concrete class is in the link subclass-of-foo. But I get always
"Cannot construct instance of Foo (no Creators, like default construct, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information".
I can't use @JsonDeserialize(as = Subclass.class) on Foo, because there are multiple sub-classes of Foo.
Where and how can I provide this information to fix the problem?
@Entity
@Inheritance(strategy = SINGLE_TABLE)
@DiscriminatorColumn(name = "type", discriminatorType = STRING)
class abstract Foo {
private id;
}
class Bar1 extends Foo {
}
class Bar2 extends Foo {
}
class Bar3 extends Foo {
}
@Entity
class X {
private String id;
@OneToOne
private Foo foo;
}
And json payload to POST an X object:
{
"id": "X_ID",
"foo": "http://localhost:8080/api/bar1/Bar1_ID"
}
