從頁面接收json格式的資料，在java類裡面進行解析

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"}]};ssss
將此字串放在ruquest或者其他的變數裡面，傳遞到後臺。
如放在reques中：
request.getRequestDispatcher("/geServlet?data="+jsonStr).forward(request,response);
在servlet或java類裡這樣接收：
String json = request.ge[size=large][/size]tParameter("data");
JSONObject jsonObject = JSONObject.fromObject(data);
String name = jsonObject.getString（“name”）；
......
//對於陣列這樣接收用
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");
......
}
}
