通过response 响应数据 json 格式

/**
   *json 格式样例
   * 
   * @param response
   * @param jsonString
   */
  public void responseJsonString(HttpServletResponse response, String jsonString) {
    ("application/json; charset=utf-8");
    byte[] bytes;
    try {
      bytes = ("UTF-8");
    } catch (UnsupportedEncodingException e) {
      throw new RuntimeException(e);
    }
    ();
    try {
      OutputStream os = ();
      (bytes);
      ();
      if (()) {
        ("Send the client " + jsonString);
      }
    } catch (IOException e) {
      ("Exception happens.", e);
      throw new RuntimeException(e);
    }finally {  
        if (os!= null) {  
            ();  
        }  
    }
  }

request通过流获取参数

piblic void getJson(HttpServletRequest request){
    BufferedReader streamReader = new BufferedReader( new                   InputStreamReader((), "UTF-8"));
    StringBuilder responseStrBuilder = new StringBuilder();
    String inputStr;
    while ((inputStr = ()) != null){
        (inputStr);
    }
    JSONObject jsonObject = (());
}
