In everyday use, we typically encounter map to json, which can take a lot of time to iterate over, but we have jars like this
The method *** is undefined for the type JSONObject Lack of which package ------
json-lib.jar
Still, you need a dependent jar or you'll get an error
java.lang.ClassNotFoundException: net.sf.ezmorph.Morpher
Dang dang & na; Jar package is ezmorph - * * *. The jar
Here's how we do it
JSONSerializer. ToJSON (map object)
Let's say our map object is
{time=2015/04/10, carNum= Beijing A2212, mark= The fender is damaged. The headlight is damaged , billNum=100232113213R}
The result after converting to json is
{"time":"2015/04/10","carNum":" Beijing A2212","mark":" The fender is damaged. The headlight is damaged ","billNum":"100232113213R"}
