I can login and logout, and display a list of users on a page doing this:
<li th:each="user : ${users}">
<span th:text="${user.firstname}+' '+${user.lastname}"></span>
</li>
I would now simply like to display the name of the currently logged in user, but I am not sure how. I would like to add it to a header fragment so every page shows clearly who the user logged in is.

UserController code for logging in:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.*;
import javax.servlet.http.HttpSession;
import javax.validation.Valid;
import java.util.List;
#Controller
#RequestMapping(value = "/user")
public class UserController {
#Autowired
UserService userService;
#RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginView(Model model)
{
LoginForm user = new LoginForm();
model.addAttribute("user", user);
return "login";
}
#RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(Model model, #Valid #ModelAttribute("user") LoginForm user, BindingResult bindingResult, HttpSession session)
{
if(bindingResult.hasErrors())
{
model.addAttribute("user", user);
model.addAttribute("message", "Please provide information in each field");
return "login";
}
if (userService.validateLogin(user)==false)
{
model.addAttribute("user", user);
model.addAttribute("message", "Your accountname and/or password are incorrect");
return "login";
}
session.setAttribute("login", true);
return "redirect:/";
}
UserService
package com.demo.spring.service;
import com.demo.spring.domain.LoginForm;
import com.demo.spring.domain.UserSearchForm;
import com.demo.spring.domain.User;
import com.demo.spring.domain.UserRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
#Service
public class UserService {
public boolean validateLogin(LoginForm user)
{
List<User> users = userRepository.checkUserInput(user.getAccountname(),user.getPassword());
return users !=null && users.size()>0;
}
We put the logged in users' name in the session
#RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(Model model, #Valid #ModelAttribute("user") LoginForm user, BindingResult bindingResult, HttpSession session)
{
...
session.setAttribute("accountName", user.getAccountName());
session.setAttribute("login", true);
return "redirect:/";
}
Once put in the session, the session variables can simply be accessed as ${session.accountName}. So you can use <span th:text="${session.accountName}"></span> in your header fragment.
I'm getting following error while running my Spring MVC web application:
Invalid property 'idUtilisateur' of bean class [com.model.Utilisateur_$$_jvstba9_0]: Getter for property 'idUtilisateur' threw exception; nested exception is java.lang.reflect.InvocationTargetException
org.springframework.beans.InvalidPropertyException: Invalid property 'idUtilisateur' of bean class [com.model.Utilisateur_$$_jvstba9_0]: Getter for property 'idUtilisateur' threw exception; nested exception is java.lang.reflect.InvocationTargetException
How can I fix it?

I've created basic form validation in Spring using annotations. For unknown reason it is displaying the NotNull error message I specified in the User class before the form is submitted. Any ideas why?

You have same method on "/" for GET and POST with #Valid and BindingResult. Create separate method for GET without parameters you don't need there.
I created a project with Spring + JPA + Hibernate. I want to pass a string from jsp to controller(removeUtente method). If I click on the link I delete the row from the database .. Where am I doing wrong? Excuse me for my english..The controller receives the string from jsp and calls the method to remove it.
Thanks

In UtilisateurHibernateDao#verify you're trying to retrieve the user from its id:
Utilisateur user = this.getUtilisateur(utilisateur.getIdUtilisateur());
But you only have the username ans password. I suggest to create another method that can return the user from its username:
public Utilisateur getUtilisateurByUsername(String username) {
Session session = HibernateUtil.getSession();
try {
session.beginTransaction();
Query q = session.createQuery("from Utilisateur as u where u.username=:username")
.setString("username", username);
return (Utilisateur) q.uniqueResult();
}
finally {
session.close();
}
}
And use this method in verify:
Utilisateur user = this.getUtilisateurByUsername(utilisateur.getUsername());
//rest of the code...
Not part of the main problem but IMO the verify method should be at service level, not at dao. Data Access Objects are meant to only retrieve and update the data to the data source, while the business rules should be in service layer.
