It's not a correct solution.
It is not possible to white list the classes.
Am moving with Jackson.

Thanks for your reply.

Maybe try using the JSONFactoryUtil.serialize() method instead?

Also, I think you'll need to add your class to this property if you want to deserialize it properly:

json.deserialization.whitelist.class.names=\

JSON deserializer fails in Liferay 7

Hi All

Am migrating the portlets from 6.2 to 7. The JSON deserialization is not working as expected.

Below is the piece of code.

Map<String, List<VO>> itemMap = new HashMap<>();

JSONSerializer serializer = JSONFactoryUtil.createJSONSerializer();
for (Entry<String, List<VO>> entry : itemMap.entrySet()) {
           MultiVMPoolUtil.getCache("masterkey").put(entry.getKey(), serializer.serialize(entry.getValue()), 60000);
       }

here the serialization doesn't happen with the class hint. In 6.2, the serialized string is
[{name: "x", age: 10, class: "com.VO"},{name: "y", age: 20, class: "com.VO"}]

but in 7 version it is
[{name: "x", age: 10},{name: "y", age: 20}]

due to this, while deserializing it back, rather than getting as List<VO> am getting List<HashMap>

In case if am try to store the object rather than serializing, am getting classcast exception. I think thats due to the classloader issue.

Can someone help on this?
