JSONArray数据转换成java List

package no.integrasco.ingentia.news.qaedition;

public class Person {

private String name;

private int age;

public String getName() {

return name;
}

public void setName(String name) {

this.name = name;
}

public int getAge() {

return age;
}

public void setAge(int age) {

this.age = age;
}
}

package no.integrasco.ingentia.news.qaedition;

import java.util.List;

import net.sf.json.JSONArray;
import net.sf.json.JsonConfig;

public class JsonTest {

/**
* @param args
*/
public static void main(String[] args) {

// 转换方法1
JSONArray array = JSONArray.fromObject("[{'name':'hehe','age':22}]");
List<Person> list = JSONArray.toList(array, Person.class);// 过时方法
System.out.println(list.get(0).getName());

// 转换方法2
List<?> list2 = JSONArray.toList(array, new Person(), new JsonConfig());//参数1为要转换的JSONArray数据，参数2为要转换的目标数据，即List盛装的数据
Person person = (Person) list2.get(0);
System.out.println(person.getAge());
}

}

从页面接收json格式的数据，在java类里面进行解析

String jsonStr = {"name":"zfj","dd":[{"ddr":"1","encrypt":"2","ff":"1","length":"23","ffe":"editStyled","ill":"1","pkor":"2","name":"zfj","isKey":"2","alias":"ffff"}],"addRelations":[{"type":"2","ld":"zfj","ld":"2"}]};

将此字符串放在ruquest或者其他的变量里面，传递到后台。

如放在reques中：
request.getRequestDispatcher("/geServlet?data="+jsonStr).forward(request,response);

在servlet或java类里这样接收：
String json = request.ge[size=large][/size]tParameter("data");
JSONObject jsonObject = JSONObject.fromObject(data);
String name = jsonObject.getString（“name”）；
......
//对于数组这样接收用

JSONArray jan = (JSONArray) jsonObject.get("dd");
if(jan!=null||jan.size()!=0){
for(int i=0;i<ja.size();i++){
JSONObject jo = JSONObject.fromObject(ja.get(i));
String ff = jo.getString("ff");
......
}
}
