'Hibernate Validator annotations not working with spring mvc

I have a problem with Hibernate Validator. I putted in my code @Size annotation but when I am running app on Tomcat server I can submit without filled text field. What is wrong with this code?

Customer class:

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

public class Customer {

    private String firstName;

    @NotNull(message="is required")
    @Size(min=1, message="is required")
    private String lastName;

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
}

CustomerController class:

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.validation.Valid;

@Controller
@RequestMapping("/customer")
public class CustomerController {

    @RequestMapping("/showForm")
    public String showForm(Model theModel) {
        theModel.addAttribute("customer", new Customer());
        return "customer-form";
    }

    @RequestMapping("/processForm")
    public String processForm(
            @Valid @ModelAttribute("customer") Customer theCustomer, BindingResult theBindingResult) {

        if (theBindingResult.hasErrors()) {
            return "customer-form";
        } else {
            return "customer-confirmation";
        }
    }
}

Solution 1:[1]

You might need to add the following bean definition in your xml.

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>

OR

for custom error messages you need to create a message.properties in the resource folder and use ResourceBundleMessageSource

<!-- bind your messages.properties -->
<bean class="org.springframework.context.support.ResourceBundleMessageSource"
    id="messageSource">
    <property name="basename" value="messages" />
</bean>

Did you try to place

 <!-- Hibernate Validator -->
  <dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
     <version>5.4.1.Final</version>
 </dependency>

in your pom.xml?

I used the jar hibernate-validator-5.1.3.Final and it worked for me. I was facing the same problem when I was using 6.

Solution 4:[4]

Restarting IntelliJ fixed this for me. Really. 25 minutes of my life I'll never get back.

Solution 5:[5]

I had the same problem.

My solution was using older version of Hybernate validator. The thing is they changed package name into jakarta. instead of javax. from version 6.2 and it was causing problems for me, because spring class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" was still implementing javax.validation.ValidatorFactory

Solution 6:[6]

I had the same problem using Hibernate Validator 7. I used Hibernate 6 and the problem was solved!

Solution 7:[7]

I was having the same problem, To solve this use @NotEmpty instead of @NotNull, this should fix the issue.
