Ignore malformed JSON fields

[tl-manishoswal]

Hi All,
I want to check if we have any such feature where in case a Malformed Json is given for a given class but the data of the field does not match (throws )it should continue parsing for the remaining fields and for the corrupt field it should set it as null .

Below is sample error I get when error is thrown
_

I tried using the JSONIgnoreProperty but that for ignoring any new fields, I am looking in case the data type does not match and it throws MismatchedInputException. I tried to look in but did not find any direct solution .

In such cases you will probably want to register DeserializationProblemHandler and catch specific failures, skip content (for extra ones); return null for missing ones. This will allow process to continue.
