使用Jackson

import android.text.TextUtils;import android.util.Log;import com.fasterxml.jackson.core.JsonProcessingException;import com.fasterxml.jackson.databind.ObjectMapper;import com.fasterxml.jackson.databind.SerializationFeature;import java.io.IOException;/** * Created by kevin on 15-1-24. */public class JsonSendUtil {    private static ObjectMapper mapper;    private static final String TAG = "JsonSendUtil";    public static final String SEND_FAILED = "1";    static {        mapper = new ObjectMapper();        //mapper.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);    }    public static synchronized  <T, U> U sendJsonForGetResult(T entity, Class<U> resultClass, String url) {        String json;        U resultEntity = null;        try {            json = mapper.writeValueAsString(entity);            if (json != null) {                String result = CustomHttpURLConnection.PostJsonToWebByHttpURLConnection(url, json);                Log.d(TAG,"result: " + result +"  Json: "+json);                if (!TextUtils.isEmpty(result)) {                    resultEntity = mapper.readValue(result, resultClass);                }            }        } catch (JsonProcessingException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        }        return resultEntity;    }}

使用

import com.fasterxml.jackson.annotation.JsonProperty;import cn.rspread.im.IMApplication;/** * Created by kevin on 15-1-23. */public class LoginOrRegisterEntity {    //{"phone":{"ApiKey":"123456","phone":"861860302645"}}    private Phone phone;    public LoginOrRegisterEntity(String phoneNumber) {        this.phone = new Phone();        phone.setApiKey(IMApplication.API_KEY);        phone.setPhone(phoneNumber);    }    public Phone getPhone() {        return phone;    }    public void setPhone(Phone phone) {        this.phone = phone;    }    public static class Phone {        @JsonProperty("ApiKey")        private String apiKey;        private String phone;        public String getApiKey() {            return apiKey;        }        public void setApiKey(String apiKey) {            this.apiKey = apiKey;        }        public String getPhone() {            return phone;        }        public void setPhone(String phone) {            this.phone = phone;        }    }}

import com.fasterxml.jackson.annotation.JsonProperty;/** * Created by kevin on 15-1-23. */public class LoginOrRegisterResultEntity {    //{"SendSmsResult":"1"}    @JsonProperty("SendSmsResult")    private String sendSmsResult;    public String getSendSmsResult() {        return sendSmsResult;    }    public void setSendSmsResult(String sendSmsResult) {        this.sendSmsResult = sendSmsResult;    }}

调用

public static boolean sendLoginOrRegister(String phone) {        if (TextUtils.isEmpty(phone)) {            return false;        }        loginPhoneNumber = phone;        LoginOrRegisterEntity loginOrRegisterEntity = new LoginOrRegisterEntity(phone);        LoginOrRegisterResultEntity resultEntity = JsonSendUtil.sendJsonForGetResult(loginOrRegisterEntity, LoginOrRegisterResultEntity.class, LOGIN_URL);        if (resultEntity==null) {            return false;        }        return ("1").equals(resultEntity.getSendSmsResult());    }
