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

     //获得结束标签的索引

             List<Integer> endIndex = new ArrayList<Integer>();

             for(int i=1; i<events.size(); i++){

                 if("22".equals(events.get(i).attributeValue("eventtype"))) {

                     endIndex.add(i);

                 }

             }

             System.out.println();

             //分组处理  跳过第一个channelText

             List<Element> list = new ArrayList<Element>();

             int count = 0;

             if(timeIndex <=endIndex.get(0)) {

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

                     if(i == 0) {

                         list = events.subList(1,endIndex.get(i)+1);

                         //插入广告

                         for(int j=timeIndex; j<list.size();j+=2) {

                             list.add(j,(Element)adEvent.clone());

                             count++;//计算插入了多少个广告

                         }

                     }else {

                         list = events.subList(endIndex.get(i-1)+1+count,endIndex.get(i)+1+count);

                         for(int j=timeIndex; j<list.size();j+=2) {

                             list.add(j,(Element)adEvent.clone());

                             count++;

                         }

                     }

                 }

             }else {

                 //为了应对插入的节点不从第一天开始

                 for(int i=0;i<endIndex.size()-1; i++) {

                     int temp1 = timeIndex - endIndex.get(i);

                     int temp2 = timeIndex - endIndex.get(i+1);

                     if(temp1 >0 && temp2 <0) {

                         /*System.out.println("temp1----|" + temp1);

                         System.out.println("temp2-----|" + temp2);*/

                         for(int j=i+1;j<endIndex.size();j++) {

                             list = events.subList(endIndex.get(j-1)+1+count,endIndex.get(j)+1+count);

                             for(int m= temp1; m<list.size()-1;m+=2) {

                                 list.add(m,(Element)adEvent.clone());

                                 count++;

                             }

                         }

                     }

                 }

             }

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

 /**

      *

      * @param beginTime  -- 广告的开始时间点

      * @return 该时间点的索引

      */

     public  static int getTimeIndex(Document document,String beginTime) {

         List<Element> events = document.getRootElement()

                                 .element("SchedulerData")

                                 .element("Channel").elements();

         System.out.println("===" + beginTime);

         Long long_beginTime1 = Long.parseLong(beginTime);

         for(int i=1;i<events.size()-1; i++) {

             if(beginTime.equals(events.get(i).attributeValue("begintime"))) {

                 return i;

             }else {

                 Long long_beginTime2  = Long.parseLong(events.get(i).attributeValue("begintime"));

                 Long long_beginTime3  = Long.parseLong(events.get(i+1).attributeValue("begintime"));

                 Long duration = Long.parseLong(events.get(i).attributeValue("duration"));

                 Long temp1 = long_beginTime1 - long_beginTime2;

                 Long temp2 = long_beginTime1 - long_beginTime3;

                 if(temp1 > 0 && temp2 <0){

                     return i;

                 }

             }

         }

         return 0;

     }

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

 if(timeIndex == 0) {

                 String begin = events.get(1).attributeValue("begintime");

                 beginTime = beginTime.replace(beginTime.substring(0,8),begin.substring(0,8));

                 timeIndex = getTimeIndex(document, beginTime);

             }

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

 public static Element createAdElement(Ad ad,String time,Map<String,String> propertiesMap) {

         if(ad == null) {

             System.out.println("广告对象为空!");

             return null;

         }

         Element adElement = DocumentHelper.createElement("Event");

         //beginTime

         if(ad.getBeginDate() != null && time != null) {

             String beginTime = ad.getBeginTime().toString();

             beginTime = beginTime.replace(":","");

             beginTime = beginTime.substring(0,4);

             beginTime = time.substring(0,8) + beginTime + "00";// --->20171103083500

             adElement.addAttribute("begintime",beginTime);

         }

         //duration

         String duration = ad.getDuration();

         if(duration != null) {

             adElement.addAttribute("duration",duration);

         }

         //eventtype

         String adEventType = propertiesMap.get("adEventType");

         if(adEventType != null) {

             adElement.addAttribute("eventtype",adEventType);

         }

         //eventid

         String eventId = "";

         adElement.addAttribute("eventid",eventId);

         //language

         String adLanguage ="chi";

         Element eventText = adElement.addElement("EventText").addAttribute("language",adLanguage);

         //name节点

         if(eventText != null) {

             Element name = eventText.addElement("name");

             if(ad.getContent() != null) {

                 name.setText(ad.getContent());

             }

         }

         return adElement;

     }

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

 /**

      * 修改广告的begintime信息与受到广告影响的节目duration

      * @param events

      */

     private void updateAdtime(List<Element> events,String adDuration) {

         for(int i=2;i<events.size();i++) {

             Attribute duration = events.get(i).attribute("duration");

             if(adDuration != null) {

                 if(duration.getText().equals(adDuration)) {

                     String lastNodeBegin = events.get(i-1).attributeValue("begintime");

                     String lastNodeDuration = events.get(i-1).attributeValue("duration");

                     if(lastNodeBegin == null || lastNodeDuration == null) {

                         System.out.println("上个节点不存在");

                         return;

                     }

                     //修改节目的持续时间

                     Long temp = Long.parseLong(lastNodeDuration);

                     temp = temp - Long.parseLong(duration.getText());

                     events.get(i-1).attribute("duration").setText(temp.toString());

                     //修改后重新获取

                     lastNodeBegin = events.get(i-1).attributeValue("begintime");

                     lastNodeDuration = events.get(i-1).attributeValue("duration");

                     //设置广告的开始时间

                     Long adBeginTime = Long.parseLong(lastNodeBegin) + Long.parseLong(lastNodeDuration);

                     String strAdBegin = adBeginTime.toString();

                     Long min = Long.parseLong(strAdBegin.substring(strAdBegin.length()-4));

                     if( min >= 6000) {

                         adBeginTime = adBeginTime + 10000 -6000;

                     }

                     strAdBegin = adBeginTime.toString();

                     events.get(i).attribute("begintime").setText(strAdBegin);

                 }

             }

         }

     }

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

 /**

      * 将修改后的xml文档重新生成

      * @param document

      * @param path

      * @param encode

      */

     public void write(Document document,String path,Map<String,String> propertiesMap) {

             String channelEncoding = propertiesMap.get("channelEncoding");

             if(channelEncoding != null) {

                 format.setEncoding(channelEncoding);

             }

             format.setNewLineAfterDeclaration(false);

             File file;

         try {

             file = new File(path);

             if(file.getParentFile().exists()) {

                 file.createNewFile();

             }else {

                 file.getParentFile().mkdirs();

                 file.createNewFile();

             }

             XMLWriter write = new XMLWriter(new FileOutputStream(file,false),format);

             write.write(document);

             write.close();

             } catch (IOException e) {

                 e.printStackTrace();

             }

     }
