实例如下：

									package com.idc.dataAudit.dataResource;

									import java.util.ArrayList;

									import java.util.HashMap;

									import java.util.Iterator;

									import java.util.List;

									import java.util.Map;

									import net.sf.json.JSONArray;

									import net.sf.json.JSONObject;

									import org.apache.commons.httpclient.HttpClient;

									import org.apache.commons.httpclient.HttpMethod;

									import org.apache.commons.httpclient.methods.GetMethod;

									public class RequestHttpManage {

									    public Map<Integer,String> RequesthttpInfo(String url) { 

									        String resultStr = null;

									        Map<Integer,String> mapResult = new HashMap<Integer,String>();

									    try{

									            HttpClient client = new HttpClient();  

									            HttpMethod method=new GetMethod(url); 

									            //使用POST方法 

									            //HttpMethod method = new PostMethod("http://java.sun.com"); 

									            client.executeMethod(method); 

									            //打印服务器返回的状态 

									            //System.out.println(method.getProtocolVersion());

									            //System.out.println(method.getStatusLine().getStatusCode());

									            //System.out.println(method.getStatusLine().getReasonPhrase());

									              // System.out.println(method.getStatusLine().toString());

									              // System.out.println(method.getStatusLine()); 

									            //打印返回的信息 

									              // System.out.println(method.getResponseBodyAsString()); 

									            mapResult.put(method.getStatusLine().getStatusCode(), method.getResponseBodyAsString());

									            //释放连接 

									            method.releaseConnection(); 

									    }catch(Exception e){

									        e.printStackTrace();

									    }

									    System.out.println(mapResult);

									    return mapResult;

									  } 

									    public Map<String,List<String>> GetMapFromJson(String jsonStr){

									    Map<String,List<String>> mapResult = new HashMap<String,List<String>>();

									    try{

									         JSONObject result = JSONObject.fromObject(jsonStr);//转换为JSONObject

									       JSONArray nameList = result.getJSONArray("result");//获取JSONArray

									       int length = nameList.size();

									       for(int i=0;i<length;i++){

									         JSONObject tempObject = nameList.getJSONObject(i);

									         Iterator iter = tempObject.keys();

									         String key = (String)iter.next();

									         String keyId = tempObject .getString(key);

									         List<String> objList = new ArrayList<String>();

									         for (; iter.hasNext();) { 

									            String keyLocal = (String)iter.next();

									          //  System.out.println(key+"="+tempObject .getString(keyLocal));

									            objList.add(tempObject .getString(keyLocal));

									         }

									         mapResult.put(keyId, objList);

									       }

									    }catch(Exception e){

									        e.printStackTrace();

									    }

									    System.out.println(mapResult);

									    return mapResult;

									  }

									}
