Solutions: 
(1) if the string is converted to json, then you need to call the json packet method (string turn json object), and then forwards the json object resolution in the past.
2. If the entity object, you need to call the Json packet method (object turn Json object), and then forwards the Json object resolution in the past.
no matter what you need to turn the object data type, anyhow can not directly return to the past for Json parsing, need to convert a Json object before parsing.
