项目分析

1.深圳移动无线市民主页

1.我负责的主要是应用管理,账号管理，Tips管理，其中应用管理包括应用新增，应用查询,应用新增里面可以添加

(新增版本(1.0,1.1),推荐指数(只能输入1-3位整数)类型(android,iphone(选择andoird时把软件路径显示,把iphone路径隐藏,否则反之)

-->js style.disply="",block不兼容火狐,none)--->页面震动(30%)),软件路径(request.getSession().getServletContext.getRealPath+File.separator)

软件Logo(实际上保存的是logo的路径),应用查询主要根据软件名称查询，再根据推荐指数，日期倒序排列

2.中国电信广研院AR平台

1.频道供应商关系管理(频道跟内容提供商是一对多的关系),内容供应商包括:新浪生活,四维地图,开开周边,号百服务 ,

频道(都市生活)包括：频道名称,频道id,频道生活

2POI信息分类(id,名称)供应商关系管理(poi(分类)包括：食宿 ,购物 ,文化等),内容供应商包括:新浪生活,四维地图,开开周边,号百服务 ,

POI信息分类跟内容提供商是多对多的关系

接口实现:

1.获取频道内容接口

(根据childid查询出频道内容,用Sax解析，方法封装转成json格式)

public String getCpContent() {

Map<String, Object> jsonObj = new HashMap<String, Object>();

String resultcode = "0";

String resultmsg = "error";

String total = "0";

String count = "0";

String page = "1";

if (!"".equals(chid) && chid != null) {

TbContentCp tb = cpService.getCpById(chid);

countChannel(chid);// 统计频道访问次数

SAXReader reader = new SAXReader();

try {

if (tb != null && tb.getCpurl().length() > 0) {

InputStream in = inPost(FormatURL(tb.getCpurl()), "");

System.out.println("URL==="+FormatURL(tb.getCpurl()));

if (in != null) {

Document doc = reader.read(in);

Element xml = doc.getRootElement();

resultcode = xml.elementText("resultcode");

resultmsg = xml.elementText("resultmsg");

total = xml.elementText("total");

count = xml.elementText("count");

page = xml.elementText("page");

Element date = xml.element("date");

Element poilist = date.element("poilist");

if (poilist != null) {

@SuppressWarnings("unchecked")

List<Element> list = poilist.elements("content");

List<POIBean> resultMap = new ArrayList<POIBean>();

if (list != null && list.size() > 0) {

for (Element content : list) {

POIBean pb = new POIBean();

pb.setCategory(content.elementText("category"));

pb.setName(content.elementText("name"));

pb.setIntroduction(content

.elementText("introduction"));

pb.setPic_url(content

.elementText("pic_url"));

pb.setAddress(content

.elementText("address"));

pb.setLatitude(content

.elementText("latitude"));

pb.setLongitude(content

.elementText("longitude"));

List<Map<String, String>> operate = new ArrayList<Map<String, String>>();

@SuppressWarnings("unchecked")

List<Element> operatelist = content

.elements("operate");

if (operatelist != null

&& operatelist.size() > 0) {

String lable, action, contentStr;

for (Element op : operatelist) {

Map<String, String> operaM = new HashMap<String, String>();

lable = op.elementText("lable");

action = op.elementText("action");

contentStr = op.elementText("content");

operaM.put("lable", lable);

operaM.put("action", action);

operaM.put("content", contentStr);

if (lable.length() > 0

&& action.length() > 0

&& contentStr.length() > 0) {

operate.add(operaM);

}

}

pb.setOperate(operate);

}

resultMap.add(pb);

}

jsonObj.put("poilist", resultMap);

}

}

}

}

} catch (DocumentException e) {

// TODO Auto-generated catch block

resultcode = "0";

resultmsg = "error";

e.printStackTrace();

} finally {

jsonObj.put("resultcode", resultcode);

jsonObj.put("resultmsg", resultmsg);

jsonObj.put("total", total);

jsonObj.put("count", count);

jsonObj.put("page", page);

jsonObj.put("keywords", keywords);

this.setXml(JsonUtil.toJson(jsonObj));

}

} else {

jsonObj.put("resultcode", resultcode);

jsonObj.put("resultmsg", resultmsg);

jsonObj.put("total", total+"");

jsonObj.put("count", count);

jsonObj.put("page", page);

jsonObj.put("keywords", keywords);

this.setXml(JsonUtil.toJson(jsonObj));

}

return SUCCESS;

}

2.获取所有频道接口

(查询出所有频道list,解析list，用jsonObject封装,最后out出去)

public String getAllChannel() {

log.debug("interface getAllChannel start");

JSONObject jsonObj = new JSONObject();

try {

List<TbContentChannel> channelList = channelService

.getAllTbContentChannel();

List<Map<String, String>> resultMap = new ArrayList<Map<String, String>>();

for (int i = 0; i < channelList.size(); i++) {

Map<String, String> channelMap = new HashMap<String, String>();

channelMap.put("id", channelList.get(i).getId());

channelMap.put("channelname", channelList.get(i)

.getChannelname());

resultMap.add(channelMap);

}

jsonObj.put("channellist", resultMap);

jsonObj.put("resultcode", "1");

jsonObj.put("resultmsg", "ok");

this.setXml(jsonObj.toString());

} catch (JSONException e) {

e.printStackTrace();

}

return SUCCESS;

}

3.珠海转换器项目(金融)

报文结构:

报文头 报文类型标识符 位 图 报文域

报文中使用位图来标识报文中有哪些域而没有哪些域。一个报文中可以有一个或两个位图位图在报文中位置如图所示：

报文头 报文类型标识符 位 图 报文域

(ThreadPoolNumberThree)线程池类用于接收来自Loadrunner来的报文,并发送给远程主机

定义一个方法用于用于接收来自远程主机来的报文

将从远程主机处理过的报文返回给Loadrunner

TransmitMachine

Socket,多线程

4.前海人寿(保险)

1.应付账款流程(用户登录后可以查看自己的应付账款,然后发给相关处理人处理,用户还可以看到自己的流程到哪一步了)

Jdeveloper,oracle ,存储过程(带参数的存储过程),function函数,weblogic(发布，把工程加到域里,domain)

5.电子商务(购物车)

主要做了购物车,处理sesion问题：禁止cookie,关闭浏览器是否保存session等等

session的作用,生命周期

session的原理

session使用细节,多浏览器共享session

重启浏览,关闭cookie的话无解

禁用cookie了--->解决方案 重写URL --->response.encodeURL

("day07/servlet/SessionDemo1");

response.encodeRedirectURL("day07/servlet/SessionDemo1");

javascript:void(0) //去掉超链接默认行为

//手工以cooie形式发sessionid,以解决关闭浏览器后，上次买的东西还在

(cooike未禁用)

客户端防表单重复提交和服务器端session防表单重复提交(服务器有延迟)

El表达式用于获取数据(${data})

6 总结

Session将信息保存在服务器上，而Cookie保存在客户端上

Session比Cookie更安全，Session比Cookie更占资源

开发原则：Session要尽量少用--尽量少向Session中保存信息

session使用了Cookie的机制，如果Cookie被禁用，则Session也无法使用,因

为客户端的session ID以cookie形式,保存在了客户端的内存当中,这个时候我

们可以通过url重写,来保证session的有效性.

重写url的方法如下

resp.encodeURL(request.getRequestURL().toString());

解决:

1.javascript阻止表单重复提交

<script type="text/javascript">

var iscommitted =false;//记录表单是否提交,2.设置按钮

不可用

function dosubmit(){

if(!iscommitted){

iscommitted =true;

return true;

}else{

return false;

}

}

</script>

2。服务器端防止表单重复提交

public class FormServlet extends HttpServlet {

public void doGet(HttpServletRequest request,

HttpServletResponse response)

throws ServletException, IOException {

//产生随机数(表单号)

TokenProccessor tp =TokenProccessor.getInstance();

String token =tp.generateToken();

boolean b =isTokenValid(request);

if(!b){

System.out.println("不要重复提交");

return;

}

request.getSession().removeAttribute("token");

System.out.println("想数据库中提交注册。。。。");

}

//判斷表單是否提交

public boolean isTokenValid(HttpServletRequest request) {

String client_token = request.getParameter("token");

if (client_token == null) {

return false;

}

String server_token = (String) request.getSession

().getAttribute(

"token");

if (server_token == null) {

return false;

}

if (!server_token.equals(client_token)) {

return false;

}

return true;

}

public void doPost(HttpServletRequest request,

HttpServletResponse response)

throws ServletException, IOException {

}

static class TokenProccessor { // 令牌

private TokenProccessor() {

}

private static final TokenProccessor instance = new

TokenProccessor();

public static TokenProccessor getInstance() {

return instance;

}

//任意的二进制数据是三个字节 ,指纹128位字节

public String generateToken() {

String token = System.currentTimeMillis() +

new Random().nextInt()

+ "";

try {

MessageDigest md =

MessageDigest.getInstance("md5");

byte[] md5 = md.digest();

//上传下载用到base64

// base64編程：把三个字节变成四个字

节 ，编之后最大不会超过64

BASE64Encoder encoder = new

BASE64Encoder();

encoder.encode(md5);

} catch (NoSuchAlgorithmException e) {

throw new RuntimeException(e);

}

return null;

}

}

6.中兴供应商协同管理系统

1.主要做了报表开发,ireport报表画出来,(供应商,项目经理,面试通过率,人员到位率等等报表)
