Question: Is there a way to specify a default subtype if there is not a
specific match in the subtypes list?
I'm new to Jackson and a novice developer, and I'm still struggling a bit
with the basics of the annotations. In my use case, the API i'm reading
from has at least 20 or 30 "Resource Types", and more will be added
regularly. Currently, I am aware of 3 or 4 types that have unique fields
and need to be cast to a special subtype for that. However, if it's not one
of a few special types, then it should just be cast as
the GenericResource type. In summary, it's impossible to maintain a
comprehensive list of the generic subtypes I might get, so I just want to
maintain the list of exceptional subtypes.
Here's my example, I'm quite sure the "type = "*"" won't work, but maybe
there's something similar?
Also, the example might not even be using the annotations properly. Please
me correct if wrong.
@JsonSubTypes({
@JsonSubTypes.Type(value = StorageResource.class, type =
"Microsoft.Storage/storageAccounts"),
@JsonSubTypes.Type(value = GenericResource.class, type = "*") })
abstract class Resource {
public String id
public String name
public String type
public String location
}
public class GenericResource extends Resource {
}
public class StorageResource extends Resource {
public Sku sku
public String kind
public Tags tags
}
Sample JSON:
{
"value" : [{
"id" :
"/subscriptions/98a83e18-54c4-402d-b38c-1d22aaf1cfa8/resourceGroups/NewTestRG/providers/Microsoft.Network/networkInterfaces/temptest425",
"name" : "temptest425",
"type" : "Microsoft.Network/networkInterfaces",
"location" : "westus2"
, {
"id" :
"/subscriptions/98a83e18-54c4-402d-b38c-1d22aaf1cfa8/resourceGroups/NewTestRG/providers/Microsoft.Storage/storageAccounts/newtestrg731",
"name" : "newtestrg731",
"type" : "Microsoft.Storage/storageAccounts",
"sku" : {
"name" : "Standard_LRS",
"tier" : "Standard"
},
"kind" : "Storage",
"location" : "westus2",
"tags" : {}
}]
}
