再遇XStream有关问题。

public class People {        private String sex;        private List userList;}public calss User {    private String name;    private String address;}

<people>    <sex>sex</sex>    <user>        <name>name</name>        <address>address</address>    </user>    <user>        <name>name</name>        <address>address</address>    </user>    <user>        <name>name</name>        <address>address</address>    </user></people>

@XStreamAlias("people")public class People {        private String sex;        @XStreamImplicit    private List<User> userList;    public String getSex() {        return sex;    }    public void setSex(String sex) {        this.sex = sex;    }    public List<User> getUserList() {        return userList;    }    public void setUserList(List<User> userList) {        this.userList = userList;    }}@XStreamAlias("user")public class User {    private String name;    private String address;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getAddress() {        return address;    }    public void setAddress(String address) {        this.address = address;    }}public class WritePeople {    public static void main(String[] args) {        People p = new People();        p.setSex("male");        List<User> list = new ArrayList<User>();        User u = new User();        u.setName("zhang");        u.setAddress("beijing");        list.add(u);                p.setUserList(list);                //Serialize the object        XStream xs = new XStream();        xs.processAnnotations(People.class);        //Write to a file in the file system        try {            FileOutputStream fs = new FileOutputStream("people.txt");            xs.toXML(p, fs);        } catch (FileNotFoundException e1) {            e1.printStackTrace();        }    }}public class ReadPeople {    public static void main(String[] args) {        XStream xs = new XStream(new DomDriver());        xs.processAnnotations(People.class);        People p = new People();        try {            FileInputStream fis = new FileInputStream("people.txt");            xs.fromXML(fis, p);            //print the data from the object that has been read            System.out.println(p.getUserList().get(0).getName());        } catch (FileNotFoundException ex) {            ex.printStackTrace();        }    }}
------解决方案--------------------
1.dto结构如下：
Java code
public class people{    private  Sex sex;    private  List<User> user;    //getter,setter}public class Sex{    private String sex;    //getter,setter}public classs User{    private String name;    private String address;    //getter,setter}

探讨


还有这样的一个问题，就是再bean-->xml 的时候，如果两个节点用的是同一个vo,那么生成xml 的时候，第一个节点会有点，当到第二个节点的时候，会出现一个reference 来引用第一个节点，这个要怎么办才能不引用 第一个节点 呢？
