xtream用于javabean和.xml文件之间的序列化与反序列化操作。下面是我自己做的相关练习，我把代码贴出来以供分享。

定义了三个类：Classes  班级类

                         Student 学生类

                        MapBean 用于单独测试map转成xml之后的xiaoguo

public class Classes {	public Classes() {		// TODO Auto-generated constructor stub	}	private String className;	private List
   
     students;	public String getClassName() {		return className;	}	public void setClassName(String className) {		this.className = className;	}	public List
    
      getStudents() {		return students;	}	public void setStudents(List
     
       students) {		this.students = students;	}	@Override	public String toString() {				System.out.println(className);		return className;	}	}
     
    
   

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

public class MapBean {	public MapBean() {		// TODO Auto-generated constructor stub	}	private Map
   
     servlet;	private Map
    
      mapping;	public Map
     
       getServlet() {		return servlet;	}	public void setServlet(Map
      
        servlet) {		this.servlet = servlet;	}	public Map
       
         getMapping() {		return mapping;	}	public void setMapping(Map
        
          mapping) { this.mapping = mapping; } }
        
       
      
     
    
   

/** * 测试X-Stream的使用 * @author 杨承 * */public class MainClass {	public static void main(String[] args){		mapToXml();	}		public static void objToXml(){		XStream xStream=new XStream(new DomDriver());		xStream.alias("student", Student.class);		xStream.alias("Classes", Classes.class);				Student stu=new Student();		Student stu2=new Student();		stu.setName("校花");		stu.setAge(23);				stu2.setName("校草");		stu2.setAge(23);				Classes classes=new Classes();		List
   
     list=new ArrayList<>();		list.add(stu);		list.add(stu2);		classes.setClassName("班级一");		classes.setStudents(list);		System.out.println(xStream.toXML(classes));	}		public static void xmlToObj(){		XStream xStream=new XStream(new DomDriver());
   

xStream.alias("student", Student.class);

xStream.alias("Classes", Classes.class);

Classes classes=new Classes();		//文件存放在项目的根目录下		xStream.fromXML(new File("Classes.xml"), classes);		classes.toString();	}			public static void mapToXml(){				XStream xStream=new XStream(new DomDriver());		xStream.alias("root", MapBean.class);				Map
   
     urlToName=new HashMap<>();		urlToName.put("/login", "login");		urlToName.put("/log", "login");		urlToName.put("/reg", "reg");				Map
    
      nameToObj=new HashMap<>();				nameToObj.put("login", "httpServer.demo3.LoginServlet");		nameToObj.put("reg", "httpServer.demo3.RegistServlet");				MapBean bean=new MapBean();		bean.setMapping(urlToName);		bean.setServlet(nameToObj);		System.out.println(xStream.toXML(bean));	}}
    
   

objToXml()的执行结果：

     
    
     班级一
      
        
           
      
       校花
            
      
       23
          
         
           
      
       校草
            
      
       23
          
       
    
   

mapToXml();执行结果

     
        
           
      
       reg
            
      
       httpServer.demo3.RegistServlet
          
         
           
      
       login
            
      
       httpServer.demo3.LoginServlet
          
       
      
        
           
      
       /login
            
      
       login
          
         
           
      
       /log
            
      
       login
          
         
           
      
       /reg
            
      
       reg
