將通過輸入流獲取json格式數(shù)據(jù)轉(zhuǎn)為map格式

轉(zhuǎn)換代碼：

try {int length = 0;//通過輸入流獲取到j(luò)son格式數(shù)據(jù)ServletInputStream inputStream = getActionRequest().getInputStream();//或者使用session和request獲取數(shù)據(jù)//ServletInputStream inputStream = session.getInputStream();//ServletInputStream inputStream = request.getInputStream();//定義數(shù)組存放數(shù)據(jù)byte buffer[] = new byte[2048];StringBuilder sb = new StringBuilder();if((length = inputStream.read(buffer)) !=-1){sb.append(new String(buffer,0,length));}Gson gson = new Gson();//將存放入數(shù)組的數(shù)據(jù)轉(zhuǎn)為map格式HashMap map = gson.fromJson(sb.toString(), HashMap.class);System.err.println("map "+map);} catch (IOException e) {e.printStackTrace();}

轉(zhuǎn)換前json格式數(shù)據(jù)：

{"response": {"version": "1.0","systemType": "NVMS-9000","status": "success","content": {"type": "list","item": { "id": "08095753-fbb2-4bc1-81c3-54d67ac" }}} }

轉(zhuǎn)換后map格式數(shù)據(jù)：

{response={version=1.0, systemType=NVMS-9000, status=success, content={type=list, item={id=08095753-fbb2-4bc1-81c3-54d67ac}}}}
