springmvc中对日期格式化的处理

时间：2023-11-26 11:03:56

@DateTimeFormat(pattern="yyyy-MM-dd")

返回的时候java.util.Date

pattern="yyyy-MM-dd"必须要和页面中的日期格式对应。

1、TimeController.java

 package com.chenk.web.controller;

 import org.springframework.stereotype.Controller;

 import org.springframework.ui.Model;

 import org.springframework.web.bind.annotation.RequestMapping;

 import com.chenk.pojo.Users;

 @Controller

 public class TimeController {

 @RequestMapping("/addUserController")

 public String addUser(Users user,Model model){

     model.addAttribute("user", user);

     System.out.println(user);

     return "showUser";

 }

 }

2.User.java

 package com.chenk.pojo;

 import java.util.Date;

 import org.springframework.format.annotation.DateTimeFormat;

 public class Users {

 private String name;

 private String age;

 //备用yyyy-MM-dd HH:mm:ss

 @DateTimeFormat(pattern="yyyy-MM-dd")

 private Date birth;

 public String getName() {

     return name;

 }

 public void setName(String name) {

     this.name = name;

 }

 public String getAge() {

     return age;

 }

 public void setAge(String age) {

     this.age = age;

 }

 public Date getBirth() {

     return birth;

 }

 public void setBirth(Date birth) {

     this.birth = birth;

 }

 @Override

 public String toString() {

     return "Users [name=" + name + ", age=" + age + ", birth=" + birth + "]";

 }

 }

3、页面

 <%@ page language="java" contentType="text/html; charset=UTF-8"

     pageEncoding="UTF-8"%>

 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

 <html>

 <head>

 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

 <title>日期</title>

 </head>

 <body>

     <form action="addUserController" method="post">

         <input type="text" name="name" />

         <input type="text" name="age" />

         <input type="text" name="birth" />

         <input type="submit" value="提交">

     </form>

 </body>

 </html>
