使用JSON传递接收集合，对象map for json,json for java

//发送方public static void main(String[] args) {String mobiles = "15810022404";String content = "发送远程API测试短信。。。";boolean needReport = true;String xcode="01201112";//01为各平台短信子号，201112为流水号（000000－999999）String uname = "tudou";content = EncryptUtils.encodeBufferBase64(content.getBytes());// base64编码，防止乱码String sendtime = DateUtils.getNowTime();uname = EncryptUtils.encodeBufferBase64(uname.getBytes());Map<String, Object> map=new HashMap<String, Object>();//使用Map集合map.put("uname", uname);Send s=new Send();s.setContent(content);s.setStarttime(DateUtils.parseDate(sendtime));s.setMobile(mobiles);s.setNeedReport(needReport);s.setXcode(xcode);map.put("data", s);//将对象放入MapString md5 = MD5Utils.getInstance().getMD5ofStr(JSON.toJSONString(s)+MD5Utils.k1);map.put("md5", md5);new SmsSendTest().testSendSms(JSON.toJSONString(map));//直接将Map转换成JSON传递}

接收方：

public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {PrintWriter out = response.getWriter();String json = request.getParameter("json").toString();JSONObject jo = JSON.parseObject(json);String md5 = jo.getString("md5");String data = jo.getString("data");System.out.println(data);Send send = JSON.parseObject(data, Send.class);String content = new String(EncryptUtils.decodeBufferBase64(send.getContent()));String uname = jo.getString("uname");String upwd = jo.getString("upwd");uname = new String(EncryptUtils.decodeBufferBase64(uname));boolean needReport = send.isNeedReport();

一个JSON封装数据的例子：

public String getModules(int todo, int offset, int pageSize, int total,int moduleNo) {total = getAllModules(todo, 0, 1, moduleNo).getTotal();int maxPage = total % pageSize == 0 ? total / pageSize : total/ pageSize + 1;if (offset < 0) {offset = 0;} else if (offset >= maxPage) {offset = maxPage - 1;}PageModel pm = getAllModules(todo, offset * pageSize, pageSize,moduleNo);List<Menu> list = pm.getDatas();JSONObject json = new JSONObject();try {JSONArray members = new JSONArray();if (list != null && list.size() > 0) {for (int i = 0; i < list.size(); i++) {JSONObject member = new JSONObject();member.put("menuId", list.get(i).getMenuId());member.put("menuNo", list.get(i).getMenuNo());member.put("parentNo", list.get(i).getParentNo());member.put("menuName", list.get(i).getMenuName());member.put("linkURL", list.get(i).getLinkURL());member.put("description", list.get(i).getDescription());members.add(i, member);}json.put("offset", offset);json.put("maxPage", maxPage - 1);json.put("total", total);json.put("menus", members);}} catch (Exception e) {e.printStackTrace();}return json.toString();}

在js中用ajax调用并显示：

function jsonview() {var total = $("total1").innerHTML;var offset = $("offset1").value;var pageSize = 5;menuDao.getModules(1,offset, pageSize, total, wirteHtml);}function wirteHtml(data) {var data = eval("(" + data + ")");// 使用eval函数var continents = data.menus;$("offset1").value = data.offset;$("maxPage1").value = data.maxPage;$("maxPage2").innerHTML = data.maxPage + 1;$("total1").innerHTML = data.total;$("curpage").innerHTML = data.offset + 1;var tab = $("mytables");var num = tab.rows.length;for ( var i = 0; i < num; i++) {if (tab.rows.length != 2) {tab.deleteRow(tab.rows.length - 2);}}for ( var i = 0; i < continents.length; i++) {var newLine = tab.rows.length;var row = tab.insertRow(newLine - 1);if (i % 2 != 0) {row.className = "odd";// 奇数行row.onmouseout = function() {this.className = "odd";}} else {row.className = "even";// 偶数行row.onmouseout = function() {this.className = "even";}}row.onmouseover = function() {this.className = "alt";}row.insertCell(0).innerHTML = "<input style=\"width:20px;\" type=\"radio\" name=\"rdoId\" value=\""+ continents[i].menuNo+ "\" title=\""+ continents[i].menuName+ "\" />";row.insertCell(1).innerHTML = continents[i].menuNo;row.insertCell(2).innerHTML = continents[i].menuName + " ";if(continents[i].description==''){row.insertCell(3).innerHTML = '暂无说明';}else{row.insertCell(3).innerHTML = continents[i].description;}}}
