首先看看2个简单的fastjson的使用
例子一
package ivyy.taobao.com.domain.json;
import java.util.Iterator;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
/**
* @Author:jilongliang
* @Date:2014-12-19
* @Version:1.0
* @Description:
*/
public class JsonTest1 {
public static void main(String[] args) {
//[{"age":22,"sex":"男","userName":"xiaoliang"},{"age":22,"sex":"男","userName":"xiaoliang"}]
StringBuffer buff=new StringBuffer();
buff.append("[");
buff.append("{");
buff.append("'age'").append(":").append("22").append(",");
buff.append("'sex'").append(":").append("'男'").append(",");
buff.append("'userName'").append(":").append("'周伯通'").append("");
buff.append("}");
buff.append(",");//第一个数组结尾
buff.append("{");
buff.append("'age'").append(":").append("22").append(",");
buff.append("'sex'").append(":").append("'男'").append(",");
buff.append("'userName'").append(":").append("'令狐冲'").append("");
buff.append("}");
buff.append("]");
String jsonStr=buff.toString();
JSONArray jarr=JSONArray.parseArray(jsonStr);//JSON.parseArray(jsonStr);
for (Iterator iterator = jarr.iterator(); iterator.hasNext();) {
JSONObject job=(JSONObject)iterator.next();
String age=job.get("age").toString();
System.out.println(age);
}
}
}
例子二
package ivyy.taobao.com.domain.json;
import ivyy.taobao.com.entity.Classz;
import ivyy.taobao.com.entity.Student;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
/**
* @Author:jilongliang
* @Date:2014-12-19
* @Version:1.0
* @Description:
*/
public class JsonTest2 {
public static void main(String[] args) {
Student stu1=new Student();
stu1.setAge(22);
stu1.setUserName("xiaoliang");
stu1.setSex("男");
Classz claz1=new Classz();
claz1.getStudents().add(stu1);
String jsonStr=JSON.toJSONString(claz1);
JSONObject jsonObj=new JSONObject();
Object obj=jsonObj.parse(jsonStr);
System.out.println(obj);
Classz clz=JSON.parseObject(jsonStr, Classz.class);
Student st=clz.getStudents().get(0);
System.out.println(st.getSex());
}
}
1和2的实体
package ivyy.taobao.com.entity;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
/**
*@Author:liangjl
*@Date:2014-12-19
*@Version:1.0
*@Description:
*/
public class Classz implements Serializable{
private List<Student> students=new ArrayList<Student>();
public List<Student> getStudents() {
return students;
}
public void setStudents(List<Student> students) {
this.students = students;
}
}
package ivyy.taobao.com.entity;
import java.io.Serializable;
/**
*@Author:liangjl
*@Date:2014-12-19
*@Version:1.0
*@Description:
*/
public class Student implements Serializable{
private Integer age;
private String sex;
private String userName;
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}
例子三、
package ivyy.taobao.com.domain.json;
import ivyy.taobao.com.utils.GlobalConstants;
import ivyy.taobao.com.utils.HttpRequestUtils;
import java.util.Iterator;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
/**
*@Author:liangjilong
*@Date:2015-1-4
*@Email:[email protected]
*@Version:1.0
*@Description这个是通过fastjson处理的
*/
public class SinaNew {
public static void main(String[] args) throws Exception {
String requestURL = GlobalConstants.getUrl(2, "json");
String jsonText = HttpRequestUtils.HttpURLConnRequest(requestURL, "GET");
//System.out.println(jsonText);
// 处理页面的json数据
int start = jsonText.indexOf("(") + 1;
jsonText = jsonText.substring(start, jsonText.lastIndexOf(")"));
String result = "";
JSONObject jsonObject = JSONObject.parseObject(jsonText);
result = jsonObject.get("result").toString();
JSONObject resObj = JSONObject.parseObject(result);
// String encoding=resObj.get("encoding").toString();//获取到编码
String dataStr = resObj.get("data").toString();
JSONArray dataArr = JSONArray.parseArray(dataStr);
String title = "", url = "", keywords = "", img = "", media_name = "";
int i=0;
for (Iterator iterator = dataArr.iterator(); iterator.hasNext();) {
JSONObject object = (JSONObject) iterator.next();
title = object.get("title").toString();// title
url = object.get("url").toString();// url
keywords = object.get("keywords").toString();// keywords
img = object.get("img").toString();// img
media_name = object.get("media_name").toString();// media_name
String newsText=GlobalConstants.getNewsContent(url);//处理新闻内容

i++;
System.out.println(title + "\n" + url + "\n" + keywords + "\n"+ url + "\n" + media_name);
}
