Spring之数据格式化

创建实体类

在每一个字段上面添加对应格式化的注解

package com.alin.AnnotationFormatter;
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;
	
	//百分数类型
	@NumberFormat(style=Style.PERCENT)
	private double discount;
	
	//货币类型
	@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;
	}

	public static long getSerialversionuid() {
		return serialVersionUID;
	}
}

创建控制器

package com.alin.AnnotationFormatter;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class FormatterController {

	@RequestMapping(value="/Form")
	public String registerForm(){
		
		return "Formatter/Form";
	}
	
	@RequestMapping(value = "/formatter")
	public String formatter(@ModelAttribute User user, Model model) {
		model.addAttribute("user",user);
		return "Formatter/success";
	}
}

Form.jsp 

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>



  
    
    
    
  
  
  
    
		日期类型
		

		整数类型
		

		百分数类型
		

		货币类型
		
		
	
  

 success.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>







	
		日期类型
		

		整数类型
		

		百分数类型
		

		货币类型
