I have the need of defining a flat POJO that maps its (flat) attributes to a nested object in its JSON specification. Better explain with code
{
"offset": 0,
"pageSize": 10,
"filter": {
"key1":"value1",
"key2": true,
....
}
}
My POJO shall look like the following:
public class Pojo {
private int offset;
private int pageSize;
private String key1;
private boolean key2;
}
So far I have tried annotating those key
properties with @JsonProperty
with its value
attribute
@JsonProperty("filter.key1")
private String key1;
But when I went into the MVC controller those properties, though set in JSON, were null in the decoded POJO.
How can I fix this? What did I do wrong?
I absolutely don't want to create nested subclasses
Might be currently impossible.
This because Jackson currently supports @JacksonUnwrapped
for the opposite case, but no @JacksonWrapped
