自己封装Jackson的工具类——JsonUtil

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;

/**

 */
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());
    }
