信息的转换，格式化，验证对于前端数据来说，

都是很有必要的。

这里实现一下格式化数据。

最重要的POJO定义如下:

user.java

package org.fkit.domain;import java.io.Serializable;import java.util.Date;import org.springframework.format.annotation.DateTimeFormat;import org.springframework.format.annotation.NumberFormat;import org.springframework.format.annotation.NumberFormat.Style;public class User implements Serializable {	/**	 * 	 */	private static final long serialVersionUID = 1L;	@DateTimeFormat(pattern="yyyy-MM-dd")	private Date birthday;		@NumberFormat(style=Style.NUMBER, pattern="#,###")	private int total;		@NumberFormat(style=Style.PERCENT)	private double discount;		@NumberFormat(style=Style.CURRENCY)	private double money;	public Date getBirthday() {		return birthday;	}	public void setBirthday(Date birthday) {		this.birthday = birthday;	}	public int getTotal() {		return total;	}	public void setTotal(int total) {		this.total = total;	}	public double getDiscount() {		return discount;	}	public void setDiscount(double discount) {		this.discount = discount;	}	public double getMoney() {		return money;	}	public void setMoney(double money) {		this.money = money;	}		}
