Fastjson ToObject transform null to empty string

Question

I use FastJSON to deserialize a json into an object. During the deserialization I would like to automatically replace all the null values in the json by an empty string. Is there a JSON parameter to do that? Otherwise, what would you suggest?

Answer 1

You can use JSON.parseObject(String json, Class<T> clazz, Feature... features) method and pass through Feature.InitStringFieldAsEmpty as last argument.
