我正在创建一个Java类来映射具有多个相同元素的XML文件。以下的XML的文件是什么样子的例子：对具有许多相同元素的XML文件使用JAXB
<TrackBroadcast>
<DateTime>some date</DateTime>
<From>from someone</From>
<To>to someone</To>
<Classification>some type of classification</Classification>
<Command>some type of command</Command>
<MsgId>some id</MsgId>
<Barge attribute1="???" attribute2="???" attribute3="" etc/> --->The Barge.java class explains the attributes
<Barge attribute1="???" attribute2="???" attribute3="" etc/> --->The Barge.java class explains the attributes
<Barge attribute1="???" attribute2="???" attribute3="" etc/> --->The Barge.java class explains the attributes
<Barge attribute1="???" attribute2="???" attribute3="" etc/> --->The Barge.java class explains the attributes
</TrackBroadcast>
我JAXB类可以在日期时间读，发件人，收件人，分类，命令和的MsgId元素，但它不能在驳船元素读取。我有两个类来试图封装XML，但我知道我做错了什么。这两个类是：
@XmlRootElement(name="TrackBroadcast")
public class TrackBroadcast {
String dataTime;
String from;
String to;
String classification;
String command;
String msgId;
List<Barge> barge = new ArrayList<Barge>();
public String getDataTime() {
return dataTime;
}
@XmlElement(name="DateTime")
public void setDataTime(String dataTime) {
this.dataTime = dataTime;
}
public String getFrom() {
return from;
}
@XmlElement(name="From")
public void setFrom(String from) {
this.from = from;
}
public String getTo() {

}
@XmlElement(name="To")

}

}

}
public String getMsgId() {
return msgId;
}
@XmlElement(name="MsgId")
public void setMsgId(String msgId) {
this.msgId = msgId;
}
public List<Barge> getBarge() {
return barge;
}
public void setBarge(List<Barge> barge) {
this.barge = barge;
}
@Override
public boolean equals(Object obj) {
if (obj == null) {
return false;
}
if (getClass() != obj.getClass()) {
return false;
}
final TrackBroadcast other = (TrackBroadcast) obj;
if ((this.dataTime == null) ? (other.dataTime != null) : !this.dataTime.equals(other.dataTime)) {
return false;

return false;
}
if (this.barge != other.barge && (this.barge == null || !this.barge.equals(other.barge))) {
return false;
}
return true;
}
@Override
public int hashCode() {
int hash = 7;
hash = 43 * hash + (this.dataTime != null ? this.dataTime.hashCode() : 0);

hash = 43 * hash + (this.barge != null ? this.barge.hashCode() : 0);
for(int i=0; i<barge.size(); i++){
Barge b = barge.get(i);
System.out.println(b.toString());
}
return hash;
}
@Override
public String toString() {
return "TrackBroadcast{" + "dataTime=" + dataTime + ", from=" + from + ", to=" + to + ", classification=" + classification + ", command=" + command + ", msgId=" + msgId + ", barge=" + barge + '}';

当我解组文件，我可以在TrackBroadcast得到的一切除了驳船。我是JAXB的新手，想知道是否有人能够看到我可能做错了什么，或者是否有人能够让我朝正确的方向发展。
这样做！谢谢！ – 2012-04-06 18:53:21
