JSON、GSON解析

今天弄微信支付时候碰到了解析数据，费了好大劲，一定要写下来

这种类型

List, String>> listOfMaps = new ArrayList, String>>();

对他进行的遍历

for (int i = 0; i < products.size(); i++) {
   Map, String> mapProduct = new HashMap, String>();
   mapProduct.put("pid", products.get(i).pid);
   mapProduct.put("puid", products.get(i).puid);
   mapProduct.put("pu_count", String.valueOf(products.get(i).pu_count));
   mapProduct.put("pu_name", products.get(i).pu_name);
   mapProduct.put("pu_description", products.get(i).pu_description);
   mapProduct.put("pu_price", products.get(i).pu_price);
   mapProduct.put("pu_point", products.get(i).pu_point);
      listOfMaps.add(mapProduct);
}

最后想要得到listOfMaps这个对象的属性

需要这样：：：

String json = new Gson().toJson(params);

将这个json打印出来

就得到这种：

{"autoCloseInputStreams":false,"contentEncoding":"UTF-8",

"elapsedFieldInJsonStreamer":"_elapsed","fileArrayParams":{},

"fileParams":{},"forceMultipartEntity":false,"isRepeatable":false,

"streamParams":{},"urlParams":{"address":"在睡觉就喜欢还好吧哈哈哈",

"reservetime":"1479988824","sendtype":"0",

"token":"focks4i59lj7ckr4ul2d8c9bn6001479978907",

"realname":"小将信将疑家","uid":"372","password":"",

"handphone":"15638191676","district":"上海市 上海市",

"ttype":"2","comment":"","reservetype":"1"},

"urlParamsWithObjects":{"products":[{"pu_count":"1",

"pid":"116","puid":"147","pu_price":"4.0"},

{"pu_count":"1","pid":"116","puid":"147","pu_price":"4.0"}]},

"useJsonStreamer":false}
