springmvc中对日期格式化的处理

@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。

contraller层：

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";
}
}

Entity

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 + "]";
}

}
