一. 简介：

xStream可以轻易的将Java对象转换成xml、JSON。本篇博客将使用springMVC整合利用xStream转换xml。

关于xStream使用的博文：http://blog.csdn.net/zdp072/article/details/39054197

二. 实例：

1. 代码结构图：

2. 实体类：

（1）Account

public class Account {
    private int id;
    private String name;
    private String email;
    private String address;
    private Birthday birthday;

    // getter and setter

    @Override
    public String toString() {
        return this.name + "#" + this.id + "#" + this.address + "#" + this.birthday + "#" + this.email;
    }
}

public class User {
	private String name;
	private int age;
	private Boolean sex;
	private String address;
	private Birthday birthday;
	
	// getter and setter
	
	@Override
    public String toString() {
        return this.name + "#" + this.age + "#" + this.sex + "#" + this.address + "#" + this.birthday.getBirthday();
    }
}

public class Birthday {
	private String birthday;

	public Birthday() {
	}
	
	// getter and setter
}

4. XstreamController
/**
