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
}

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？
