This Gsonutils.getgson (). Fromjson (Exhimain.getqitafressjson (), New typetoken<list<qitafree>> () when you turn the generic type into a collection. {}.gettype ());

If such as this turn list<string> fanlist = Gsonutils.getgson (). Fromjson (Exhimain.getfanwei (), arraylist.class); It doesn't work.

The String type is stored in JSON format and can be turned into a generic collection

Gsonutils.getgson (). Fromjson () Turn generic collection
