XStream xml与javabean之间的互转

XStream是thoughtworks公司发布的一个简单的Java类库，用于将JavaBean序列化为XML，并且能够将XML文件反向转换为JavaBean.

实例:

user.java

BaseBean.java

importjava.util.ArrayList;
1. importjava.util.List;
2. classBaseBean{
3. privateList<User>userList;
4. publicBaseBean(){
5. userList=newArrayList<User>();
6. publicList<User>getUserList(){
7. returnuserList;
8. voidsetUserList(List<User>userList){
9. this.userList=userList;
10. voidaddUser(Useruser){
11. userList.add(user);
12. 
    xstream代码
    copy
    classXStreamTest{
    1. staticvoidmain(String[]args){
    2. //javabean转xml
    3. List<User>users=newArrayList<User>();
    4. users.add(newUser("123","爱边程","23"));
    5. users.add(newUser("456","刘大拿","24"));
    6. BaseBeanbase=newBaseBean();
    7. base.setUserList(users);
    8. XStreamxs=newXStream();
    9. xs.alias("root",BaseBean.class);
    10. xs.alias("user",User.class);
    11. xs.aliasField("list",153); font-weight:bold; background-color:inherit">class,"userList");
    12. Stringxml=xs.toXML(base);
    13. System.out.println("javabean转成xml为:n"+xml);
    14. //xml转javabean
    15. XStreamxs1=newXStream(newDomDriver());
    16. xs1.alias("root",153); font-weight:bold; background-color:inherit">class);//注意此处要把原要转换的bean类定义别名为根节点的名字，如上面的xml的根节点为<root>
    17. xs1.alias("user",153); font-weight:bold; background-color:inherit">class); //此处与上面相同
    18. xs1.aliasField("list",108); list-style:decimal-leading-zero outside; color:inherit; line-height:18px; margin:0px!important; padding:0px 3px 0px 10px!important"> base=(BaseBean)xs1.fromXML(xml);
    19. users=base.getUserList();
    20. System.out.println("xml转成javabean为:");
    21. for(Useru:users){
    22. System.out.println("id="+u.getId()+",name="+u.getName()+",age="+u.getAge());
    23. }
