XStream 简单使用

XStream是一个JavaBean和XML互转换的根据类库。不需要映射文件，使用简单，不过很久没更新了。

使用很简单，直接代码：

public class Student {
    private String firstName;
    private String secondName;
    private int age;

｝

public class Classz {
    private String name;
    private String id;
   
    private List<Student> students = new LinkedList<Student>();

｝

   
    public static void main(String[] args) {
        marshall();
        unmarshall();
    }
   
    public static void marshall() {
        Student s = new Student();
        s.setAge(26);
        s.setFirstName("liu");
        s.setSecondName("wh");
       
        Classz c = new Classz();
        c.addStudent(s);
        c.setName("class name");
       
       
        // 不指定别名，XML的元素名为类的全限定类名
        XStream xStream = new XStream();
        System.out.println(xStream.toXML(c));
       
        xStream.alias("student", Student.class);
        xStream.alias("class", Classz.class);
        System.out.println(xStream.toXML(c));
    }
   
    public static void unmarshall() {
        String xml = "<class>" +
                "  <name>class name</name>" +
                "  <students class=\"linked-list\">" +
                "    <student>" +
                "      <firstName>liu</firstName>" +
                "      <secondName>wh</secondName>" +
                "      <age>26</age>" +
                "    </student>" +
                "  </students>" +
                "</class>";
       
        XStream xStream = new XStream(new DomDriver());
       
        xStream.alias("class", Classz.class);
        xStream.alias("student", Student.class);
       
        Classz c = (Classz)xStream.fromXML(xml);
       
        System.out.println(c.getName());
       
    }
   

 

使用要注意的是：

如果没有为类指定别名，将使用类的全限定类名作为XML元素的名字。
