逐层解析请求json参数字符串【我】

import net.sf.json.JSONObject;

逐层解析请求json参数字符串：

        InputStream inStream =null;
        BufferedReader br =null;
        String reJson="";
        String rtJson="";
        String tranId="";

        //返回报文字段
        String resultCode = "1";
        String resultMsg = "失败";
        try {
            httpRequest.setCharacterEncoding("UTF-8");
            inStream = httpRequest.getInputStream();
            String reqUrl= httpRequest.getRequestURI();
            syslogger.info(reqUrl);
            String[] method = reqUrl.split("/", 0);
            Map headMap = this.getHeaderMap(httpRequest);
            Map params = this.getParameterMap(httpRequest);
            syslogger.info(params);
             br = new BufferedReader(new InputStreamReader(inStream,"UTF-8"));
             String str=br.readLine();
             StringBuffer json = new StringBuffer();
             while (str != null) {
                try {
                    json.append(str);
                    str =  br.readLine();

                    throw new CommonRunException(blExc.getMessage(), blExc, "");
                }
            }
             reJson=json.toString();
             syslogger.info("resultlog 请求------------"+json);
//             String httpMethod = httpRequest.getMethod().toUpperCase();
             System.out.println("resultlog 请求------------"+json);

                tranId=RequestUtil.getMapValue(headMap,"X-CTG-Request-ID");
            }
            //调用实现类参数
             String param = "";
            try {
                //逐层解析报文获取请求参数
                JSONObject jsobRst1 = JSONObject.fromObject(json.toString());
                syslogger.info("jsobRst1 请求------------"+jsobRst1);
                String svcCont = jsobRst1.getString("svcCont");
                JSONObject requestObject = JSONObject.fromObject(svcCont);
                param = requestObject.get("requestObject").toString();
                param = jsobRst1.toString();
            } catch (Exception e) {
                System.out.println("请求参数解析出错------------str:"+json);
                syslogger.info("解析报文出错  请求------------"+e);
                throw new Exception("解析报文出错  请求------------"+e);
            }
