这是一个XML 请问用Xstream解析的时候应该怎样构建类
目前我的类是
//Groupinfo
public class Groupinfo {

private List persons=new ArrayList();

public List getPersons() {
    return persons;
}

public void setPersons(List persons) {
    this.persons = persons;
}
private void addPeron(Person person){
    persons.add(person);
}

}
//Person
public class Person {
private String name;
private String age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}

}

解析的时候回报错，请问该那么设计类

还有要声明ImplicitCollection

[quote]
XStream stream = new XStream();
stream.alias("groupinfo",GroupInfo.class);
stream.addImplicitCollection(GroupInfo.class, "persons");
stream.alias("person", Person.class);
[/quote]

[code="java"]

public class Groupinfo
{

public void setPerson(List persons)

public List getPerson();

}

[/code]

参照 xstream的文档
http://xstream.codehaus.org/alias-tutorial.html

把 private void addPeron(Person person){
persons.add(person);
}

改成

public void add(Person person){
persons.add(person);
}
