Java server-side JSON result set data output format to the front end

When outputting JSON data on the server, the Time field is output in a certain format, and Fastjson supports two ways:
1. Using the Json.tojsonstringwithdateformat method
2.json.tojsonstring method to increase Serializerfeature.writedateusedateformat parameters
The disadvantage of the first method is that if Json.deffault_date_format = "Yyyy-mm-dd hh:mm" is not called when deserializing; Set the time format, the deserialization will fail!
