Android 使用GSON / JAVA使用genson

gson

1.下载gson-2.3.1.jar ， 放到项目libs里

2.对象转json字符串

Gson gson=new Gson();String senddatastr=gson.toJson(obj);

3.json字符串转对象

Gson gson=new Gson();return gson.fromJson(packetContent.toString(),PackageCls.class);

可以对返回结果再强制转换一次

JAVA使用genson

genson

Genson genson = newGenson();

String json = genson.serialize(777.777); // the output will be 777.777

genson.serialize(true); // output is true (without quotes)

 

genson.deserialize("777", int.class); // deserializes it into 777

genson.deserialize("777.777", Object.class); // will return 777.777 (a double)

genson.deserialize("null", Object.class); // will return null;
