通过HttpservletRequest接收json数据

	public String intercept(ActionInvocation invocation) throws Exception {

		HttpServletRequest request = ServletActionContext.getRequest();	  
        接收json数据
        BufferedReader streamReader = new BufferedReader( new 
        InputStreamReader(request.getInputStream(), "UTF-8"));
        StringBuilder responseStrBuilder = new StringBuilder();
        String inputStr;
        while ((inputStr = streamReader.readLine()) != null)
             responseStrBuilder.append(inputStr);
         转化成json对象
        JSONObject jsonObject = JSONObject.fromObject(responseStrBuilder.toString());
        获取其中的对象
        JSONObject commonRequest=jsonObject.getJSONObject("commonRequest");
        获取对象中的字段
        String accessKey=commonRequest.getString("accessKey");
        获取其中的list数据
        List custList=(List) jsonObject.get("custList");
        获取的是字符串
        String  couponGroupId=jsonObject.getString("couponGroupId");
}
      

这是传的json数据

    "commonRequest": {
    "accessKey": "1", 
    "tradeNo": "00010", 
    "tradeTime": "111111111",
