Hibernate Validator #NotNull not working properly

Hibernate Validator #NotNull not working properly - java

I am trying to make simple validation form using Hibernate Validator. I have two fields in my Customer class, and i want one of them to be required (lastName).
The point is that even when im not filling this field I am not getting error message and BindingResult does not contain any errors. Is there anything im missing in my code?
Here is my Customer class snippet.
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 String getLastName() {
return lastName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
Here is Controller
#Controller
#RequestMapping("/customer")
public class CustomerController {
//adding new customer to model
#RequestMapping("/showForm")
public String showForm(Model theModel){
theModel.addAttribute("customer", new Customer());
return "customer-form";
}
//Validating passed customer attribute/object
//Biding result object holds validation results
#RequestMapping("/processForm")
public String processForm(
#Valid #ModelAttribute("customer") Customer theCustomer, BindingResult theBindingResult) {
if (theBindingResult.hasErrors()){
return "customer-form";
}
return "customer-confirmation";
}
}
EDIT: form code:
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%# page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Customer Registration Form</title>
</head>
<body>
<style>
.error{color: red}
</style>
<i> Fill out the form. Asteriks (*) means required. </i>
<br><br>
<form:form action="processForm" modelAttribute="customer">
First name: <form:input path="firstName" />
<br><br>
Last name (*): <form:input path="lastName"/>
<form:errors path="lastName" cssClass="error" />
<input type="submit" value="Submit"/>
</form:form>
</body>
</html>
EDIT 2:
I added to classpath validation-api.jar (contains the abstract API and the annotation scanner).
Also inserted #InitBinnder just to make sure that empty form field will always be null not empty String.
#InitBinder
public void initBinder(WebDataBinder dataBinder) {
StringTrimmerEditor stringTrimmerEditor = new StringTrimmerEditor(true);
dataBinder.registerCustomEditor(String.class, stringTrimmerEditor);
}
But it still seems that those annotations never get triggered at all
EDIT 3: After calling validator on Entity I am getting error:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is javax.validation.NoProviderFoundException: Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.
although i have added it to classpath
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
Validator validator = factory.getValidator();
validator.validate(theCustomer);
EDIT 4: Adding Spring Configuration files:
web.xml

EDIT 5: According to what #eis said i added to my mvc-validation-demo.xml:
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalVa‌lidatorFactoryBean"/‌>
And i also have Hibernate Validator in my classpath:
Classpath
but the error still remains

Deleteing .idea , clearing cache and new configuration did the job for me. It seems that somehow it didn't saw hibernate-validator.jar.
Thank you to everyone who contributed.

I solved this issue by adding a no argument constractor. If you are using Lombok, you only need to add #NoArgsConstructor annotation:
#AllArgsConstructor
#NoArgsConstructor
#Getter
#ToString
#EqualsAndHashCode
public class User {
private Long userId;

You have to put bean into model before rendering the jsp.
For example, you need to declare a method below at EmployeeController and access the jsp through the method.
#RequestMapping("index")
public String index(Model model) {
model.addAttribute("employee", new Employee());
return "EmployeeForm";
}
Similar question: Neither BindingResult nor plain target object for bean name available as request attribute

You have not put a bean with the name "employee" into the model. You should inject one before rendering the view. Add a method to your controller to do that.

add this to your form element :

update your controller

#RequestMapping(value = "/showEmployee", method = RequestMethod.POST)
public String showEmployee(#ModelAttribute("employee")EmployeeForm employeeForm, ModelMap modelMap){

I assume the problem is in your JSP at this line:
<input type="hidden" name="id">
Your id has no value, so there will be a NumberFormatException when trying to convert an empty string to an int.

#RequestMapping(value = "save", method = RequestMethod.POST)
I think "save.html" should be changed to just "save".

Change
<form:form action="save.html" method="post" commandName="user">
use:
<form:form action="save" method="post" commandName="user">
Because #RequestMapping value is url format.
Make changes at Controller:
#RequestMapping(value = "save", method = RequestMethod.POST)
public String createUser(#ModelAttribute(value = "user") User u) throws SQLException, ClassNotFoundException {
UserDAO udao=new UserDAO();
udao.insert(u);
return "redirect:user.html" ;
Return View Name only not an extension:
return "redirect:user" ;

How to add entry to MS SQL table?

I have a task that must keep data in MS SQL server. That is like simple registration form. I have to enter name, last name, address, and birthday and press submit button. After that the inputting data should be save in database. I don't know how to make it. Here is my code:
JSP PAGE:
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Welcome to Test Project</title>
</head>
<body>
Customer List
<h:form>
<h1>Add person</h1>
<p>Please fill in all fields and click Submit</p>
<label id="firstNameLabel">First name</label>
<input id="inputFirstName" value="${customerBean.firstName}"/>
<label id="lastNameLabel">Last name</label>
<input id="inputLastName" value="${customerBean.lastName}"/>
<label id="nirthdayLabel">Birthday name</label>
<input id="inputBirthday" value="${customerBean.birthday}"/>
<label id="addressLabel">Address name</label>
<input id="inputAddress" value="${customerBean.address}"/>
<button id="addAddPerson" value="#{customerBean., hsr1)">Add new person</button>
</h:panelGrid>
</h:form>
</body>
</html>
Another JSP page:
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Customer List</title>
</head>
<body>
<h1>Customer List</h1>
<table border="1">
<th>First Name</th><th>Last Name</th><th>Birthday</th><th>Address</th>
<c:forEach items="${customerList}" var="customer">
<tr>
<td>${customer.firstName}</td><td>${customer.lastName}</td>
<td>${customer.birthday}</td><td>${customer.address}</td>
</tr>
</c:forEach>
</table>
Add new person
