java框架---->Xstream的使用（一）

　　Xstream可以轻易的将Java对象和xml文档相互转换，而且可以修改某个特定的属性和节点名称。今天我们就简单的学习一下xstream的用法。

Xstream的简单实例

项目的结构如下，设计到三个类：

一、maven中添加xstream的依赖

<dependency>
    <groupId>com.thoughtworks.xstream</groupId>
    <artifactId>xstream</artifactId>
    <version>1.4.9</version>
</dependency>

二、java中使用到的javaBean类

• PhoneNumber类：

public class PhoneNumber {
    private int code;
    private String number;

    public PhoneNumber(int code, String number) {
        this.code = code;
        this.number = number;
    }

    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }
}

• Person类：

public class Person {
    private String firstname;
    private String lastname;
    private PhoneNumber phone;
    private PhoneNumber fax;

    public Person(String firstname, String lastname) {
        this.firstname = firstname;
        this.lastname = lastname;
    }

    public String getFirstname() {
        return firstname;
    }

    public void setFirstname(String firstname) {
        this.firstname = firstname;
    }

    public String getLastname() {
        return lastname;
    }

    public void setLastname(String lastname) {
        this.lastname = lastname;
    }

    public PhoneNumber getPhone() {
        return phone;
    }

    public void setPhone(PhoneNumber phone) {
        this.phone = phone;
    }

    public PhoneNumber getFax() {
        return fax;
    }

    public void setFax(PhoneNumber fax) {
        this.fax = fax;
    }
}

三、我们的测试类XstreamMain

public class XstreamMain {

    public static void main(String[] args) {
        XStream xstream = new XStream();
//        XStream xstream = new XStream(new StaxDriver());

        Person joe = new Person("Liu", "Ling");
        joe.setPhone(new PhoneNumber(155, "1234-456"));
        joe.setFax(new PhoneNumber(271, "9999-999"));

        String xml = xstream.toXML(joe);
        System.out.println(xml);

        Person person = (Person) xstream.fromXML(xml);
        System.out.println(person.getFirstname()); // Liu
    }
}

四、程序的运行结果如下：

<com.linux.huhx.xstream.Person>
  <firstname>Liu</firstname>
  <lastname>Ling</lastname>
  <phone>
    <code>155</code>
    <number>1234-456</number>
  </phone>
  <fax>
    <code>271</code>
    <number>9999-999</number>
  </fax>
</com.linux.huhx.xstream.Person>
Liu

如果程序中XstreamMain类加上代码：xstream.alias("person", Person.class); 那么上述的<com.linux.huhx.xstream.Person>会被替换为：<person>
