Thymeleaf form causes errors at th:field

Thymeleaf form causes errors at th:field - java

I'm very new to Thymeleaf and I'm trying to make a registration form but it keeps giving me error 500's when I try to add th: attributes to my form. I assume it has something to do with the form not seeing the UserModel but I can't be sure. I feel like I've tried everything so any help would be greatly appreciated!
Here's my registration form:
<!DOCTYPE html>
<html xmlns:th=”http://www.thymeleaf.org” xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout" layout:decorate="layouts/defaultTemplate">

<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no">
<title>Register - AZSnowSports</title>
</head>
<body>
<div layout:fragment="content">
<form action="#" th:action="#{doRegister}" th:object="${userModel}" method="POST">

</form>

Here's my controller:
package com.azsnowsports.controller;
import javax.validation.Valid;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import com.azsnowsports.model.UserModel;
#Controller
#RequestMapping("/register")
public class RegisterController {
#GetMapping("/")
public String display(Model model)
{
// Display the login form view
model.addAttribute("title", "Register Form");
return "register";
}
#PostMapping("/doRegister")
public String doRegister(#Valid UserModel userModel, BindingResult bindingResult, Model model)
{
//Check for validation errors
if (bindingResult.hasErrors())
{
model.addAttribute("title", "Register Form");
return "register";
}
return "registerSuccess";
}
}
And here's my user model:
package com.azsnowsports.model;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
public class UserModel {
/**

*/
#NotNull(message="FirstName is a required field.")
#Size(min = 1, max = 32, message="First Name must be between 1 and 32 characters.")
private String firstName;
/**

#NotNull(message="Last name is a required field.")
#Size(min = 1, max = 32, message="Last name must be between 1 and 32 characters.")
private String lastName;

public UserModel(String firstNameVal, String lastNameVal, String emailVal, String addressVal,
int phoneNumberVal, String usernameVal, String passwordVal)
{
this.firstName = firstNameVal;
this.lastName = lastNameVal;
this.email = emailVal;
this.address = addressVal;
this.phoneNumber = phoneNumberVal;
this.username = usernameVal;
this.password = passwordVal;
}
/**

*/
public String getFirstName() {
return firstName;
}
/**
* #param firstName the firstName to set
*/
public void setFirstName(String firstName) {
this.firstName = firstName;
}
/**
* #return the lastName
*/
public String getLastName() {
return lastName;
}
/**
* #param lastName the lastName to set
*/
public void setLastName(String lastName) {
this.lastName = lastName;
}
/**
* #return the email
*/
public String getEmail() {
return email;
}
/**
* #param email the email to set
*/
public void setEmail(String email) {
this.email = email;
}
/**
* #return the address
*/
public String getAddress() {
return address;
}
/**
* #param address the address to set
*/
public void setAddress(String address) {
this.address = address;
}
/**
* #return the phoneNumber
*/
public int getPhoneNumber() {
return phoneNumber;
}
/**
* #param phoneNumber the phoneNumber to set
*/
public void setPhoneNumber(int phoneNumber) {
this.phoneNumber = phoneNumber;
}
/**
* #return the username
*/
public String getUsername() {
return username;
}
/**
* #param username the username to set
*/
public void setUsername(String username) {
this.username = username;
}
/**
* #return the password
*/
public String getPassword() {
return password;
}
/**
* #param password the password to set
*/
public void setPassword(String password) {
this.password = password;
}
}
Heres a screenshot of my file structure:

I added model.addAttribute("userModel", new UserModel()); into the root map of the model so it now looks like this:
#GetMapping("/")
public String display(Model model)
{
// Display the login form view
model.addAttribute("title", "Register Form");
model.addAttribute("userModel", new UserModel());
return "register";
}
This fixed it and it runs fine now!

BindigResult.hasErrors It doesn't work Spring frameworkd validation

I am working with the Spring Framework, I have a model mapped to a controller with which I am trying to do some validations with the annotations offered by Spring, I use the BindingResult hasErrors() interface and also the #Validate annotation, however although I leave fields empty in my models (and specifies the #NotEmpty annotation) I can't get the hasErrors to change its state, it stays false. Am I forgetting something?

Every thing seems to be fine. Try changing your controller this way . Create a new object when sending it to the form like below instead of sending it through parameter as it might not be able to bind object properly:
#GetMapping("/register")
public String formLoggin(Model model, BindingResult result)
{
model.addAttribute("Title", "Registro");
model.addAttribute("cliente",new cliente()); //change this line
return "register";
}
#PostMapping("/register")
public String sendForm(#Valid #ModelAttribute("cliente") Cliente cliente, BindingResult send, Model model)
{
model.addAttribute("data", "Registro");
if(send.hasErrors()){ <-- Does not evaluate this condition
return "register";
}
model.addAttribute("cliente", cliente);
return "dataUser";
}

This is generally a result from only including the javax.validation API and not an implementation. You probably have something like the following in your depenendencies list.
<dependency>
<groupId>jakarta.validation</groupId>
<artifactId>validation-api</artifactId>
<version>2.0.1.Final</version>
</dependency>
This is only the API not an implementation. This is much like including the JPA jakarta.persistence-api and expect JPA to work (but you still need an implementation like Hibernate ORM). For the validation this is the same you need an implementation, mostly used is hibernate-validator. So you could add
<dependency>
<groupId>org.hibernate.validator</groupId>
<artifactId>hibernate-validator</artifactId>
<version>6.2.5.Final</version>
</dependency>
NOTE: You have to use version 6.x as 7+ is for the new Jakarta Validation API which isn't supported yet (as of Spring Framework 6 / Spring Boot 3 it will).
However as you are already using Spring Boot I would strongly encourage you to use.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
This will include both the API and an implementation (the aformentioned hibernate-validator one). It will make sure you have a compatible version for this version of Spring / Spring Boot.

Instead of annotating with '#NotEmpty' you can follow this method:
#Column(name= "Correo_electronico", nullable = false)
private String email;
When you use this method either Jpa or Hibernate will throw an error if the value is empty.

Why is the controller saving the user with null property fields

Basically, Spring crashes with this error "value [null]; codes [NotNull.user.email,NotNull.email,NotNull.java.lang.String,NotNull]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [user.email,email]; arguments []; default message [email]]; default message [must not be null], Field error in object 'user' on field 'firstName': rejected value [null]; codes" everytime I try to submit the completeProfile form. So, naturally, I looked at what data was saved after clicking submit on form. It turns out that the User object saved was having all the submitted property from the form as null. I checked inside the controller what was passed inside, all submitted properties from the form were null. Why does this happen?

Spring binding checkbox with Set of Objects

I would like to build a form to save an User. I have 2 tables, User and UserRole as described in Spring Security. To save an user I need to create a User Object that contains a field Set. I want to create a list of checkboxes and map them into an Set of UserRoles, but I don't know how to map them with checkboxes. I have the following classes:
#Controller
public class UserController {
#Autowired
IUserService userService;
/** Default GET form handler for users, in submission will call saveRegistration */
#RequestMapping(value="/createuser", method=RequestMethod.GET)
public String createUser(Model model) {
// User form will be bind to this User object
model.addAttribute("user", new User());
// Code about adding the user roles to JSP?
// Maybe something like this?:
// User u = new User ("useruser","123456",false);
// Set<UserRole> roles = new HashSet<UserRole>();
// roles.add(new UserRole(u,"ROLE_ADMIN"));
// roles.add(new UserRole(u,"ROLE_USER"));
// model.addAttribute("roles", roles);
return "createuser";
}
/** This method will be called on form submission, handling POST request,
* It also validates the user input */
#RequestMapping(value="/createuser", method=RequestMethod.POST)
public String doCreateUser(Model model, #Valid User user, BindingResult result) {
if(result.hasErrors()) {
return "createuser";
}
userService.createUser(user,user.getUserRole()) //createUser(User user, Set<UserRole> role)
return "success";
}
}

I don’t think #ModelAttribute is the correct annotation here. For BindingResult to work, you also need #Valid on the form bean.

Stuck in ManagedBeanPreProcessingException : Unexpected error processing managed bean

Can anyone help us with this?
We're trying to make the register user feature in our JSF application. We want the user log in right after he registers. After the user hits the I'm a new client commandLink, we have this exception, and we don't know how to handle it:

com.sun.faces.mgbean.ManagedBeanPreProcessingException: Unexpected error processing managed bean registerBean
This means that processing the bean properties on RegisterBean directly after its construction has failed miserably due to a developer error (wrong configuration, inaccessible properties, invalid property type, etc). The root cause of the problem should be visible as root cause part in the stacktrace of the exception. Since you didn't share the entire stacktrace, it's hard to tell what exactly is failing.
Anyway, just read the stacktrace. The answer is in there.
Update: as per the full stacktrace:
Caused by: com.sun.faces.mgbean.ManagedBeanPreProcessingException: Unexpected error processing managed property loginBean
Caused by: java.lang.NullPointerException
The managed property for loginBean could not be set in registerBean. Verify if there is a setter in RegisterBean class and it has the right signature.
public void setLoginBean(LoginBean loginBean) {
this.loginBean = loginBean;
}
Unrelated to the concrete problem, this NullPointerException should really have been a PropertyNotWritableException. What JSF impl/version are you using?
