servlet下的接口，获取传过来的参数

    private static String receivePost(HttpServletRequest request) {
        String result = "";
        try {
            request.setCharacterEncoding("UTF-8");
            ServletInputStream in = request.getInputStream();
            BufferedReader bf = new BufferedReader(new InputStreamReader(in, "UTF-8"));
            StringBuffer buffer = new StringBuffer();
            String line = "";
            while ((line = bf.readLine()) != null) {
                buffer.append(line);
            }
            if (null != buffer && buffer.length() > 0) {
                result = URLDecoder.decode(buffer.toString(), "UTF-8");// 转成String并解码。
            }
        } catch (Exception e) {
            e.printStackTrace();
            result = "-1";
        }

        return result;
    }

//下面是接口的方法，receivePost()调用上面的接收参数方法获取远程参数
public static void messageSynchronization(HttpServletRequest request,HttpServletResponse response){
        String obj = receivePost(request);
        PrintWriter out=null;
        // 定义变量保存将要返回的页面和错误信息
        try {
            out = response.getWriter();
            response.setContentType("text/json");
            if (StringUtils.isNotEmpty(obj) && obj != "-1") {
                ****接口的主逻辑代码****
                    }
                    out.println("{"result":"1"}");
                }else{
                    out.println("{"result":"0"}");
                }
            }    
        }catch (IOException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
            out.println("{"result":"-1"}");
        }finally{
            if(out!=null){
                out.flush();
                out.close();
            }
        }
    }
