@XmlRootElement 注解的好处是可以，让对象和xml之间方便转换；

@XmlRootElement(name = "XMLTest")
    public class XMLTest implements Serializable {
    	
    	
    	
    	public static void XMLTest() {
    		try {
    			JAXBContext jc = JAXBContext.newInstance(XMLTest.class);
    			Marshaller ms = jc.createMarshaller();
    			XMLTest st = new XMLTest();
    			st.setMailContent("邮件内容");
    			st.setMailSubject("邮件主题");
    			st.setMailTo("给袁义锐");
    			StringWriter writer = new StringWriter();
    			ms.marshal(st, writer);
    			String result = writer.toString();
    			System.out.println("对象转XML字符串： "+ result +"\n");
    			System.out.println("---------------------------------------- \n");
    			Unmarshaller unmarshaller = jc.createUnmarshaller();
    			XMLTest _XMLTest = (XMLTest) unmarshaller
    					.unmarshal(new StringReader(result));
    			
    			System.out.println("翻转XML为对象："+_XMLTest.getMailContent());
    		} catch (JAXBException e) {
    			e.printStackTrace();
    		}
    	}
    	
    
    	private static final long serialVersionUID = 641996587236478146L;
    	private String mailTo;
    	private String mailSubject;
    	private String mailContent;
    
    	public String getMailTo() {
    		return mailTo;
    	}
    
    	public void setMailTo(String mailTo) {
    		this.mailTo = mailTo;
    	}
    
    	public String getMailSubject() {
    		return mailSubject;
    	}
    
    	public void setMailSubject(String mailSubject) {
    		this.mailSubject = mailSubject;
    	}
    
    	public String getMailContent() {
    		return mailContent;
    	}
    
    	public void setMailContent(String mailContent) {
    		this.mailContent = mailContent;
    	}
    
    	
    
    	public static void main(String args[]) {
    		XMLTest();
    	}
    
    }
