python json和java json的使用

1、python json

import jsondata={       "id" : 123,       "name" : "Henry Smith",       "age" : 28,       "salary" : 2000,       "designation" : "Programmer",       "address" : {          "street" : "Park Avn.",          "city" : "Westchester",          "zipcode" : 10583       },      "phoneNumbers" : [ 654321, 222333 ],      "personalInformation" : {          "gender" : "Male",          "maritialstatus" : "Married"      }  } print type(data)                    # <type 'dict'>print type(data['phoneNumbers'])    # <type 'list'>print type(data['address'])         # <type 'dict'>print data.keys()d1 = json.dumps(data)               # json.dumps()是将字典转化为json字符串print type(d1)                      # <type 'str'>print d1                            #{                                    #    "salary": 2000,                                     #     "phoneNumbers": [654321, 222333],                                     #     "name": "Henry Smith",                                     #     "designation": "Programmer",                                     #     "address": {                                    #            "city": "Westchester",                                     #            "street": "Park Avn.",                                     #            "zipcode": 10583                                    #      },                                     #      "personalInformation": {                                    #            "gender": "Male",                                     #             "maritialstatus": "Married"                                    #      },                                     #     "age": 28,                                     #     "id": 123                                    #}d2 = json.loads(d1)                 # json.loads()是将json字符串转化为字典print type(d2)                      # <type 'dict'>print d2                            # {u'salary': 2000, u'phoneNumbers': [654321, 222333], u'name': u'Henry Smith',                                     # u'designation': u'Programmer', u'age': 28, u'address': {u'city': u'Westchester',                                     # u'street': u'Park Avn.', u'zipcode': 10583}, u'personalInformation':                                     # {u'gender': u'Male', u'maritialstatus': u'Married'}, u'id': 123}

2、java json

1)java json的相关包：json-lib-2.4-jdk15，其依赖包有：ezmorph-1.0.6、commons-logging-1.1.1、commons-lang-2.5、commons-collections-3.2.1和

commons-beanutils-1.8.0

2）基本用法

import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import net.sf.json.JSONArray;import net.sf.json.JSONObject;public class Test {public static void main(String[] args) {String data = "{"+"'id': 123,"+"'name' : 'Henry Smith',"+"'age' : 28,"+"'salary': 2000,"+"'designation' : 'Programmer',"+"'address' : {"+"'street' : 'Park Avn.',"+"'city' : 'Westchester',"+"'zipcode' : 10583"+"},"+"'phoneNumbers' : [ 654321, 222333 ],"+"'personalInformation' : {"          +"'gender' : 'Male', "         +"'maritialstatus' : 'Married'"      +"}" +"}";JSONObject json = JSONObject.fromObject(data);System.out.println(json.get("id"));System.out.println(json.getJSONArray("phoneNumbers"));System.out.println(json.getJSONArray("phoneNumbers").get(0));System.out.println(json.get("address"));System.out.println(json.getJSONObject("address").get("city"));// 数组转化为 jsonArrayint[] phoneNumbers = {654321, 222333};JSONArray jsonArray = JSONArray.fromObject(phoneNumbers);System.out.println(jsonArray.toString());// List转化为 jsonArrayList<Integer> phoneNumbers2 = new ArrayList<Integer>();phoneNumbers2.add(654321);phoneNumbers2.add(222333);JSONArray jsonArray2 = JSONArray.fromObject(phoneNumbers2);System.out.println(jsonArray2.toString());// Map转化为 jsonObjectMap<String, Object> map = new HashMap<String,Object>();map.put("id", 123);map.put("age", 28);map.put("phoneNumbers", phoneNumbers);Map<String, Object> map2 = new HashMap<String,Object>();map2.put("street", "Park Avn.");map2.put("city", "Westchester");map2.put("zipcode", "10583");map.put("address", map2);JSONObject jsonMap = JSONObject.fromObject(map);System.out.println(jsonMap.toString());}}
