在属性上添加注解
@DateTimeFormat(pattern = “yyyy-MM-dd”)
private Date birthday;文章来源地址https://www.toymoban.com/news/detail-709538.html

package com.test.pojo;

import org.springframework.format.annotation.DateTimeFormat;

import java.util.Date;

public class Users {

    private int uid;

    private String uname;

    private String pwd;

    //地址对象
    private Address address;
    @DateTimeFormat(pattern = "yyyy-MM-dd")
    private Date birthday;

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    public int getUid() {
        return uid;
    }

    public void setUid(int uid) {
        this.uid = uid;
    }

    public String getUname() {
        return uname;
    }

    public void setUname(String unamea) {
        this.uname = uname;

    public String getPwd() {

    public void setPwd(String pwd) {
        this.pwd = pwd;

    public Address getAddress() {
        return address;

    public void setAddress(Address address) {

    @Override
