JSONArray数据转换成java List

1.后台接收json数组转成封装实体类的List：

package no.integrasco.ingentia.news.qaedition;
public class Person {
</span><span style="color: #0000ff">private</span><span style="color: #000000"> String name;

</span><span style="color: #0000ff">private</span> <span style="color: #0000ff">int</span><span style="color: #000000"> age;

</span><span style="color: #0000ff">public</span><span style="color: #000000"> String getName() {

    </span><span style="color: #0000ff">return</span><span style="color: #000000"> name;
}

</span><span style="color: #0000ff">public</span> <span style="color: #0000ff">void</span><span style="color: #000000"> setName(String name) {

    </span><span style="color: #0000ff">this</span>.name =<span style="color: #000000"> name;
}

</span><span style="color: #0000ff">public</span> <span style="color: #0000ff">int</span><span style="color: #000000"> getAge() {

    </span><span style="color: #0000ff">return</span><span style="color: #000000"> age;
}

</span><span style="color: #0000ff">public</span> <span style="color: #0000ff">void</span> setAge(<span style="color: #0000ff">int</span><span style="color: #000000"> age) {

    </span><span style="color: #0000ff">this</span>.age =<span style="color: #000000"> age;
}

}
package no.integrasco.ingentia.news.qaedition;
import java.util.List;
import net.sf.json.JSONArray;

import net.sf.json.JsonConfig;
public class JsonTest {
</span><span style="color: #008000">/**</span><span style="color: #008000">
 * </span><span style="color: #808080">@param</span><span style="color: #008000"> args
 </span><span style="color: #008000">*/</span>
<span style="color: #0000ff">public</span> <span style="color: #0000ff">static</span> <span style="color: #0000ff">void</span><span style="color: #000000"> main(String[] args) {

    </span><span style="color: #008000">//</span><span style="color: #008000"> 转换方法1</span>
    JSONArray array = JSONArray.fromObject("[{'name':'hehe','age':22}]"<span style="color: #000000">);
    List</span>&lt;Person&gt; list = JSONArray.toList(array, Person.<span style="color: #0000ff">class</span>);<span style="color: #008000">//</span><span style="color: #008000"> 过时方法</span>
    System.out.println(list.get(0<span style="color: #000000">).getName());

    </span><span style="color: #008000">//</span><span style="color: #008000"> 转换方法2</span>
    List&lt;?&gt; list2 = JSONArray.toList(array, <span style="color: #0000ff">new</span> Person(), <span style="color: #0000ff">new</span> JsonConfig());<span style="color: #008000">//</span><span style="color: #008000">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</span>
    Person person = (Person) list2.get(0<span style="color: #000000">);
    System.out.println(person.getAge());
}

}

2.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");

......

}

} 

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.getParameter("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");

......

}

}
