@Size Validator is not working in my Spring Project

Question

Hi i am trying to put validation in my spring project but it is not working for me i also add all the required validator jar in my lib folder.

My Controller Class is looking like

package qm;

import java.sql.Date;
import java.text.SimpleDateFormat;

import javax.validation.Valid;

import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class StudentAdmissionController {

    @InitBinder
    public void initBinder(WebDataBinder binder) {
        binder.setDisallowedFields(new String[] {"studentSkill","studentDOB"});
        SimpleDateFormat dateFormat=new SimpleDateFormat("dd-mm-yyyy");
        binder.registerCustomEditor(Date.class,"studentDOB", new CustomDateEditor(dateFormat, false));
    }

    @RequestMapping(value="/registration.html",method=RequestMethod.GET)
    public ModelAndView getStudentAdmissionForm() {
        ModelAndView model=new ModelAndView("AdmissionForm");

        return model;
    }

    @ModelAttribute
    public void addCommonObject(Model model) {
        model.addAttribute("headerMessage","Q-Manager.com");
    }

    @RequestMapping(value="/submit-detail.html",method=RequestMethod.POST)
    public ModelAndView studentDetail(@Valid @ModelAttribute("student1") Student student,BindingResult result) {
        if(result.hasErrors()) {
            ModelAndView model=new ModelAndView("AdmissionForm");
            return model;
        }       
        ModelAndView model=new ModelAndView("AdmissionSuccess");
        return model;

    }


}

my Student Class is

package qm;

import java.util.ArrayList;
import java.util.Date;

import javax.validation.constraints.Size;

public class Student {

    @Size(min=2,max=30)
    private String studentName;

    private String studentHobby;
    private Long studentMobile;
    private Date studentDOB;
    private ArrayList<String> studentSkill;
    private Address studentAddress;

    public String getStudentName() {
        return studentName;
    }
    public void setStudentName(String studentName) {
        this.studentName = studentName;
    }
    public String getStudentHobby() {
        return studentHobby;
    }
    public void setStudentHobby(String studentHobby) {
        this.studentHobby = studentHobby;
    }
    public Long getStudentMobile() {
        return studentMobile;
    }
    public void setStudentMobile(Long studentMobile) {
        this.studentMobile = studentMobile;
    }
    public Date getStudentDOB() {
        return studentDOB;
    }
    public void setStudentDOB(Date studentDOB) {
        this.studentDOB = studentDOB;
    }
    public ArrayList<String> getStudentSkill() {
        return studentSkill;
    }
    public void setStudentSkill(ArrayList<String> studentSkill) {
        this.studentSkill = studentSkill;
    }
    public Address getStudentAddress() {
        return studentAddress;
    }
    public void setStudentAddress(Address studentAddress) {
        this.studentAddress = studentAddress;
    }


}

my Address Class is

package qm;

public class Address {

    private String country,city,street,pincode;

    public String getCountry() {
        return country;
    }

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

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getStreet() {
        return street;
    }

    public void setStreet(String street) {
        this.street = street;
    }

    public String getPincode() {
        return pincode;
    }

    public void setPincode(String pincode) {
        this.pincode = pincode;
    }

}

and Here is my AdmissionForm.jsp

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
<html>
    <head>
        <title>Student Form</title>
    </head>

                <form:errors path="student1.*"/>

            <form action="submit-detail.html" method="post">

anyone suggest me the where i am wrong so i will correct my code actually in my previous research i found that most of the people suggest regarding the jars ie need so i define all the required jars for validation in spring.

1. classmate-1.0.0 jars
2. hibernate-validator-annotation-processor-5.1.2.Final jar
3. jboss-logging-3.1.3.ga jar
4. validation-api-1.1.0.final

I used Spring 4.3.* jars for this project

Answer 1

Try by adding below dependency in your pom.xml

<dependency>
    <groupId>org.hibernate</groupId>
     <artifactId>hibernate-validator</artifactId>
    <version>6.0.12.Final</version>
</dependency>

Answer 2

you need to add mvc annotation tag in spring dispatcher.

 <mvc:annotation-driven/>
