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(":","");

adElement.addAttribute("begintime",beginTime);

//duration
String duration = ad.getDuration();

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

//language

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();
}
}
