Spring mvc validation example annotation using @valid annotation

            This tutorial shows you how to validate a bean with jsr 303 standard and uses the properties file to load the error message (resource bundle)

JSR 303 bean validation using javax standards

package com.candidjava.spring.bean;

import java.util.List;

import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

public class User
private String name;

private List<String> language;

private String country;

private String gender;

@Size(min=8, max=20)
private String password;

@Size(min=1, message="Email feild can't blank")
private String email;

public String getName() {
return name;

public void setName(String name) {
this.name = name;

public List<String> getLanguage() {
return language;

public void setLanguage(List<String> language) {
this.language = language;

public String getCountry() {
return country;

public void setCountry(String country) {
this.country = country;

public String getGender() {
return gender;

public void setGender(String gender) {
this.gender = gender;

public String getPassword() {
return password;

public void setPassword(String password) {
this.password = password;

public String getEmail() {
return email;

public void setEmail(String email) {
this.email = email;

@valid in spring controller

package com.candidjava.spring.controller;

import javax.validation.Valid;

import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.servlet.ModelAndView;

import com.candidjava.spring.bean.User;

public class UserController {

User users = new User();
public ModelAndView register(User user) {
return new ModelAndView("register");

public ModelAndView create(@Valid User user, BindingResult bindingResult) {
ModelAndView model = new ModelAndView("view");
// user bean will be automatically binded to view refer @ModelAttribute
return new ModelAndView("register");
return model;

public ModelAndView viewData(User user) {

ModelAndView model = new ModelAndView("register");
return model;
