利用org.json将json字符转成java对象

String josnString = "{'name':'zhang'}";

   if(josnString != null){

        //取空格 换行 回车
        Pattern p = Pattern.compile("\\s*|\t|\r|\n");
        Matcher m = p.matcher(josnString.toString()); 
        String after = m.replaceAll(""); 
                try {

                //取对象名
                JSONObject a = new JSONObject(after);
                   System.out.println(a.get("name"));
   } catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }    }
