说明: 1.修改后的xml间隔插入了广告,如从每天的6点开始接下来每天6点都要插入广告
2.eventid,begintime,duration进行了变化如eventid = 1 ----------> 03001
3.原xml的eventid每一天是相连的,即第一天结束eventid是35,第二天开始的eventid是36但是
修改后的eventid是每天从1开始
4.广告的持续时间是确定的
个人思路:插入广告后再进行属性的调整
知识点1:间隔插入节点
插入节点之前需要准备好用到的adEvent(广告节点)我已经提前创建,已经插入广告的时间点(timeIndex),后面会给出对应的方法
最初的想法是遍历节点的集合进行i+=2的操作,突然发现这种想法的致命缺陷在于间隔插入要求i+=2和遍历要求的i++互相冲突,于是开始思考采用分组的方式来避免
仔细观察了下xml文档,发现可以用每天的结束标签进行分组,于是先获得结束标签的索引,然后遍历每个组进行插入,有人可能问了,这样不还是冲突.实际上这个时候的遍历和间隔插入已经不再使用同一个参数i了所以不再有冲突
注意:1.使用了java集合的sublist(...)方法进行集合的截取操作
2.要使用Element对象的clone方法,否则会报 The Content already has an existing parent xxx的异常
1 //获得结束标签的索引
2 List<Integer> endIndex = new ArrayList<Integer>();
3 for(int i=1; i<events.size(); i++){
4 if("22".equals(events.get(i).attributeValue("eventtype"))) {
5 endIndex.add(i);
6 }
7 }
8 System.out.println();
9 //分组处理 跳过第一个channelText
10 List<Element> list = new ArrayList<Element>();
11 int count = 0;
12 if(timeIndex <=endIndex.get(0)) {
13 for(int i=0;i<endIndex.size(); i++) {
14 if(i == 0) {
15 list = events.subList(1,endIndex.get(i)+1);
16 //插入广告
17 for(int j=timeIndex; j<list.size();j+=2) {
18 list.add(j,(Element)adEvent.clone());
19 count++;//计算插入了多少个广告
20 }
21 }else {
22 list = events.subList(endIndex.get(i-1)+1+count,endIndex.get(i)+1+count);
23 for(int j=timeIndex; j<list.size();j+=2) {
24 list.add(j,(Element)adEvent.clone());
25 count++;
26 }
27 }
28 }
29 }else {
30 //为了应对插入的节点不从第一天开始
31 for(int i=0;i<endIndex.size()-1; i++) {
32 int temp1 = timeIndex - endIndex.get(i);
33 int temp2 = timeIndex - endIndex.get(i+1);
34 if(temp1 >0 && temp2 <0) {
35 /*System.out.println("temp1----|" + temp1);
36 System.out.println("temp2-----|" + temp2);*/
37 for(int j=i+1;j<endIndex.size();j++) {
38 list = events.subList(endIndex.get(j-1)+1+count,endIndex.get(j)+1+count);
39 for(int m= temp1; m<list.size()-1;m+=2) {
40 list.add(m,(Element)adEvent.clone());
41 count++;
42 }
43 }
44 }
45 }
46
47 }
以下的方法涉及的参数Map<String,String> propertiesMap是封装了的配置文件的信息
获得timeIndex的方法
1 /** 2 * 3 * @param beginTime -- 广告的开始时间点 4 * @return 该时间点的索引 5 */ 6 public static int getTimeIndex(Document document,String beginTime) { 7 List<Element> events = document.getRootElement() 8 .element("SchedulerData") 9 .element("Channel").elements(); 10 System.out.println("===" + beginTime); 11 Long long_beginTime1 = Long.parseLong(beginTime); 12 for(int i=1;i<events.size()-1; i++) { 13 if(beginTime.equals(events.get(i).attributeValue("begintime"))) { 14 return i; 15 }else { 16 Long long_beginTime2 = Long.parseLong(events.get(i).attributeValue("begintime")); 17 Long long_beginTime3 = Long.parseLong(events.get(i+1).attributeValue("begintime")); 18 Long duration = Long.parseLong(events.get(i).attributeValue("duration")); 19 Long temp1 = long_beginTime1 - long_beginTime2; 20 Long temp2 = long_beginTime1 - long_beginTime3; 21 if(temp1 > 0 && temp2 <0){ 22 return i; 23 } 24 } 25 } 26 return 0; 27 }
使用timeIndex时要特别注意,一旦timeIndex为0说明节目的日期变了,此时要校对广告的开始时间
1 if(timeIndex == 0) {
2 String begin = events.get(1).attributeValue("begintime");
3 beginTime = beginTime.replace(beginTime.substring(0,8),begin.substring(0,8));
4 timeIndex = getTimeIndex(document, beginTime);
5 }
创建adEvent的方法,调用的时候是从数据库读取广告信息进行创建
1 public static Element createAdElement(Ad ad,String time,Map<String,String> propertiesMap) { 2 if(ad == null) { 3 System.out.println("广告对象为空!"); 4 return null; 5 } 6 Element adElement = DocumentHelper.createElement("Event"); 7 //beginTime 8 if(ad.getBeginDate() != null && time != null) { 9 String beginTime = ad.getBeginTime().toString(); 10 beginTime = beginTime.replace(":",""); 11 beginTime = beginTime.substring(0,4); 12 beginTime = time.substring(0,8) + beginTime + "00";// --->20171103083500 13 adElement.addAttribute("begintime",beginTime); 14 } 15 //duration 16 String duration = ad.getDuration(); 17 if(duration != null) { 18 adElement.addAttribute("duration",duration); 19 } 20 //eventtype 21 String adEventType = propertiesMap.get("adEventType"); 22 if(adEventType != null) { 23 adElement.addAttribute("eventtype",adEventType); 24 } 25 26 //eventid 27 String eventId = ""; 28 adElement.addAttribute("eventid",eventId); 29 30 //language 31 String adLanguage ="chi"; 32 Element eventText = adElement.addElement("EventText").addAttribute("language",adLanguage); 33 34 //name节点 35 if(eventText != null) { 36 Element name = eventText.addElement("name"); 37 if(ad.getContent() != null) { 38 name.setText(ad.getContent()); 39 } 40 } 41 return adElement; 42 }
知识点2 更新受到广告影响的节目的开始时间(begintime)以及持续时间(duration)
说明:此方法较为简单,只需判断下一个节点是不是广告从而进行相应的调整即可
1 /** 2 * 修改广告的begintime信息与受到广告影响的节目duration 3 * @param events 4 */ 5 private void updateAdtime(List<Element> events,String adDuration) { 6 for(int i=2;i<events.size();i++) { 7 Attribute duration = events.get(i).attribute("duration"); 8 if(adDuration != null) { 9 if(duration.getText().equals(adDuration)) { 10 String lastNodeBegin = events.get(i-1).attributeValue("begintime"); 11 String lastNodeDuration = events.get(i-1).attributeValue("duration"); 12 if(lastNodeBegin == null || lastNodeDuration == null) { 13 System.out.println("上个节点不存在"); 14 return; 15 } 16 //修改节目的持续时间 17 Long temp = Long.parseLong(lastNodeDuration); 18 temp = temp - Long.parseLong(duration.getText()); 19 events.get(i-1).attribute("duration").setText(temp.toString()); 20 21 //修改后重新获取 22 lastNodeBegin = events.get(i-1).attributeValue("begintime"); 23 lastNodeDuration = events.get(i-1).attributeValue("duration"); 24 25 //设置广告的开始时间 26 Long adBeginTime = Long.parseLong(lastNodeBegin) + Long.parseLong(lastNodeDuration); 27 String strAdBegin = adBeginTime.toString(); 28 Long min = Long.parseLong(strAdBegin.substring(strAdBegin.length()-4)); 29 if( min >= 6000) { 30 adBeginTime = adBeginTime + 10000 -6000; 31 } 32 strAdBegin = adBeginTime.toString(); 33 events.get(i).attribute("begintime").setText(strAdBegin); 34 } 35 } 36 } 37 38 }
知识点3 更新eventid,以1103为例1---->03001, 10------>03010
注意:id和begintime的dd相关,注意判断原id的长度
/** * 修改id * 1-->03001 10--->03010 */ private void updateId(List<Element> events) { if(events.size() == 0) { return; } List<List<Element>> groups = new ArrayList<List<Element>>(); for(int i=1; i<events.size(); i++){ Attribute oldId = events.get(i).attribute("eventid"); String time = events.get(i).attributeValue("begintime"); String sb = ""; if(time != null){ sb = time.substring(6,8); // 截取dd } if(i<10) { sb += "00" + i; }else if(i<100) { sb += "0" + i; } if(oldId != null){ oldId.setText(sb); } if("22".equals(events.get(i).attributeValue("eventtype"))) { if(events.size()> (i+1)) { List<Element> list = events.subList(i+1,events.size()); groups.add(list); } } } for(int i=0; i<groups.size(); i++) { List<Element> subList = groups.get(i); for(int j=0; j<subList.size(); j++) { Attribute oldId = subList.get(j).attribute("eventid"); String time = subList.get(j).attributeValue("begintime"); String sb = ""; if(time != null){ sb = time.substring(6,8); // 截取dd } if(j<10) { sb += "00" + (j+1); }else if(j<100) { sb += "0" + (j+1); } if(oldId != null){ oldId.setText(sb); } } } }
知识点4 生成修改后的xml
1 /**
2 * 将修改后的xml文档重新生成
3 * @param document
4 * @param path
5 * @param encode
6 */
7 public void write(Document document,String path,Map<String,String> propertiesMap) {
8 String channelEncoding = propertiesMap.get("channelEncoding");
9 if(channelEncoding != null) {
10 format.setEncoding(channelEncoding);
11 }
12 format.setNewLineAfterDeclaration(false);
13 File file;
14 try {
15 file = new File(path);
16 if(file.getParentFile().exists()) {
17 file.createNewFile();
18 }else {
19 file.getParentFile().mkdirs();
20 file.createNewFile();
21 }
22 XMLWriter write = new XMLWriter(new FileOutputStream(file,false),format);
23 write.write(document);
24 write.close();
25 } catch (IOException e) {
26 e.printStackTrace();
27 }
28 }
