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)
     /**
* 获取频道内容
*
* @return
*/
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)
      /**
* 获取所有频道
*
* @return
*/
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
/**
* 1.把构造方法私有 2.自己创建一个 3.对外暴露一个方
法,允许获取上面创建的对象
*/
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)
