java调用淘宝api联网查询ip归属地

淘宝返回的数据为：
{"code":0,"data":{"country":"\u4e2d\u56fd","country_id":"cn","area":"\u534e\u4e1c","area_id":"300000","region":"\u5c71\u4e1c\u7701","region_id":"370000","city":"\u4e1c\u8425\u5e02","city_id":"370500","county":"","county_id":"-1","isp":"\u8054\u901a","isp_id":"100026","ip":"60.214.183.158"}}

用法：

string arr1 = getaddressbyip.getaddressbyip("120.192.182.1");
system.out.println(arr1);

详细请看代码
