使用的jar包

json-lib-2.2.2-jdk15.jar 

ezmorph-1.0.4.jar

commons-lang-2.1.jar

commons-logging-1.2.jar

commons-collections-3.2.2.jar

commons-beanutils-1.9.3.jar

代码如下：

import java.util.HashMap;import java.util.Iterator;import java.util.Map;import net.sf.json.JSONArray;import net.sf.json.JSONObject;public class testJsonToMap {    public static Map
    
      getMapFromJson(String jsonString) {        JSONObject jsonObject = JSONObject.fromObject(jsonString);        Map
     
       map = new HashMap
      
       ();        for (Iterator
        iter = jsonObject.keys(); iter.hasNext();) {            String key = (String) iter.next();            String value=jsonObject.getString(key);            if(org.apache.commons.lang.StringUtils.isNotBlank(value)&&!"null".equalsIgnoreCase(value))            {                map.put(key, jsonObject.getString(key));            }        }        return map;    }    public static JSONObject mapToJson(Map
       
         map) throws Exception {        //JSONArray array_test = new JSONArray();        //array_test.add(map);        JSONObject jsonObject = JSONObject.fromObject(map);        return jsonObject;    }    public static void main(String[] args) throws Exception {        String jsonString = "{\"data\":\"test\",\"result\":\"200\",\"codeUrl\":\"url\",\"imageValue\":\"html\"}";        Map
        
          map = new HashMap
         
          (); //JSON转Map map = getMapFromJson(jsonString); System.out.print(map.get("data")+","); System.out.print(map.get("result")+","); System.out.print(map.get("codeUrl")+","); System.out.println(map.get("imageValue")); map.remove("imageValue"); //Map转JSON JSONObject jsonObject = mapToJson(map); System.out.println(jsonObject.toString()); }}
         
        
       
      
     
    

（模拟效果，就不做trycatch异常处理了.....直接抛）

输出结果：

test,200,url,html
