How to get ActiveUser after UserProfile edit using SpringSecurity

I have a page in which user can edit its profile including username. I can get User model with the help of #AuthenticationPrincipal using the below controller:-
#RequestMapping(value = "/editCustomerProfile", method = RequestMethod.GET)
public String editCustomerProfileGet(#AuthenticationPrincipal User activeUser,Locale locale, Model model) {
Customer customer = customerService.getCustomerByUsername(activeUser.getUsername());
model.addAttribute("customer", customer);
return "editCustomer";
}
Update controller method as below:-
#RequestMapping(value = "/updateCustomer", method = RequestMethod.POST)
public String updateCustomerProfilePost(#Valid #ModelAttribute("customer") Customer customer, BindingResult result, Model model, HttpServletRequest request){
customerFormValidator.validate(customer, result);
if(result.hasErrors()){
model.addAttribute("customer", customer);
return "editCustomer";
}
List<Customer> customerList = customerService.getAllCustomers();
for (int i=0; i< customerList.size(); i++){
if(customer.getUsername().equals(customerList.get(i).getUsername())){
model.addAttribute("usernameMsg", "Username already exists");
model.addAttribute("customer", customer);
return "editCustomer";
}
}
Customer existingCustomer=customerService.getCustomerById(customer.getCutomerId());
existingCustomer.setCustomerName(customer.getCustomerName());
existingCustomer.setBillingAddress(customer.getBillingAddress());
existingCustomer.getBillingAddress().setCustomer(existingCustomer);
existingCustomer.setShippingAddress(customer.getShippingAddress());
existingCustomer.getShippingAddress().setCustomer(existingCustomer);
existingCustomer.setUsername(customer.getUsername());
existingCustomer.getUser().setUsername(customer.getUsername());
Customer editedCustomer=customerService.updateCustomer(existingCustomer);
customerSecurityService.updateEditCustomerUserAuthentication(editedCustomer, request);
model.addAttribute("message", "Customer Information Updated Successfully.");
return "editCustomerSuccess";//information page
}
Used method of CustomerSecurityServiceImpl as below:-
#Override
public void updateEditCustomerUserAuthentication(Customer customer, HttpServletRequest request) {
final Users user = customer.getUser();
final Authorities authorities = customerService.getUserAuthoritiesById(user.getUsersId());
UsernamePasswordAuthenticationToken result = new UsernamePasswordAuthenticationToken(user.getUsername(),null, Arrays.asList(new SimpleGrantedAuthority(authorities.getAuthority())));
result.setDetails(user);
SecurityContextHolder.getContext().setAuthentication(result);
}
Error after user profile change once and try again raise error as below:-

After editing the user information, it is reflecting correctly but when I again try to edit the same user then #AuthenticationPrincipal active user return null. Please advice me how I do add the user in authentication principle to reuse the above editCustomerProfileGet method.
Thank you very much.

Actually you have passed username as a principal in authentication token, whereas User object needs to be passed which will be used in subsequent authentication calls internally.
Change your code to
UsernamePasswordAuthenticationToken result = new UsernamePasswordAuthenticationToken(user,user.getPassword(), Arrays.asList(new SimpleGrantedAuthority(authorities.getAuthority())));

No matter what I did on the attribute, effDate, either change it to type Date or Timestamp, even use #temporal annotation, it just did not work and keep complaining about the same problem.
By the way, this is a embedded key model. I don't know if it matters or not.
Here is what I do in my model. Please help me find where I did wrong.

the file presenting this error is:
<%# taglib prefix="json" uri="http://www.atg.com/taglibs/json" %>
<json:object>
<json:array name="produto" var="item" items="${lista}">
<json:object>
<json:property name="id" value="${item.id}"/>
<json:property name="nome" value="${item.nome}"/>
<json:property name="categoria" value="${item.categoria}"/>
</json:object>
</json:array>
</json:object>
and the method from controller which map this file is:
#RequestMapping(value="listagem.json")
public ModelAndView listagem_json() {
ModelAndView mav = new ModelAndView();
mav.addObject("lista", produto.listagem());
mav.setViewName("listagem_produto");
return mav;
}
#RequestMapping(value="listagem_por_categoria.json", method=RequestMethod.GET)
public ModelAndView listagem_por_categoria_json(HttpServletRequest request, HttpServletResponse response) {
String id_categoria = request.getParameter("id");
ModelAndView mav = new ModelAndView();
if(id_categoria == null)
mav.addObject("lista", produto.listagem());
else
mav.addObject("lista", produto.listagem_por_categoria(id_categoria));
mav.setViewName("listagem_produto");
return mav;
}
Note: the error only is triggered when I call the second method. The methods listagem() and listagem_por_categoria() from my service class are implemented this way:
#Transactional
public List<Produto> listagem() {
return produto.findAll();
}
#Transactional
public Produto listagem(int id) {
return produto.findById(id);
}
#Transactional
public List<Produto> listagem_por_categoria(String id_categoria) {
return produto.findByField("categoria", id_categoria);
}
and in my DAO class, the methods findAll(), findById() and findByField(), are implemented this way:
#SuppressWarnings("unchecked")
#Transactional
public E findById(int id) {
E instance = (E) sessionFactory.getCurrentSession().get(entity, id);
return instance;
}
#SuppressWarnings("unchecked")
#Transactional
public List<E> findByField(String field, String value) {
String expressao = entity.toString();
String nome_classe = new String();
StringTokenizer st = new StringTokenizer(expressao);
while (st.hasMoreTokens()) {
nome_classe = st.nextToken();
}
String query = "from "+nome_classe+" where "+field+" = :data";
Query q = sessionFactory.getCurrentSession().createQuery(query);
q.setParameter("data", value);
List<E> instance = q.list();
return instance;
}
#SuppressWarnings("unchecked")
#Transactional
public List<E> findAll() {
return (List<E>) sessionFactory.getCurrentSession().createCriteria(entity).setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list();
}
anyone can see what's wrong with all that implementations?

Check this lines
String query = "from "+nome_classe+" where "+field+" = :data";
q.setParameter("data", value);
You pass value as a String, when hibernate construct a query it it replace a parameter with String. I think for category.Id you are using int type.
Logic is following:
It expects Id as int and instead it gets String, then you got an exception.
upd:
If you don't want change implementation dramatically use setParameter(String name, Object val, Type type) to set column value correctly.
To get type use sessionFactory.getClassMetadata(Class.class).getPropertyType("filedName")

Then I solve this problem by implementing two variations for the method findByField, one which accepts a String value, and other an Integer. The final code for this methods are:
#SuppressWarnings("unchecked")
#Transactional
public List<E> findByStringField(String field, String value) {
String expressao = entity.toString();
String nome_classe = new String();
StringTokenizer st = new StringTokenizer(expressao);
while (st.hasMoreTokens()) {
nome_classe = st.nextToken();
}
String query = "from "+nome_classe+" where "+field+" = :data";
List<E> instance = sessionFactory.getCurrentSession().createQuery(query).setString("data", value).list();
return instance;
}
#SuppressWarnings("unchecked")
#Transactional
public List<E> findByIntegerField(String field, Integer value) {
String expressao = entity.toString();
String nome_classe = new String();
StringTokenizer st = new StringTokenizer(expressao);
while (st.hasMoreTokens()) {
nome_classe = st.nextToken();
}
String query = "from "+nome_classe+" where "+field+" = :data";
List<E> instance = sessionFactory.getCurrentSession().createQuery(query).setInteger("data", value).list();
return instance;
}

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to com.spring.webapp.lojavirtual.acesso.persistence.model.Usuario

In my spring project, I have implemented a generic class to serve as base for all my Dao class. By example, my class UsuarioHome have this code:
#Repository
public class UsuarioHome extends Dao<Usuario> {
public UsuarioHome() {
super(Usuario.class);
}
}
and my generic class has this code:
public class Dao<E> {
private final E entity;
#Autowired
SessionFactory sessionFactory;
protected Session getCurrentSession(){
return sessionFactory.getCurrentSession();
}
public Dao(E entity) {
this.entity = entity;
}
#SuppressWarnings("unchecked")
public Dao(Class<?> classe) {
this.entity = (E) classe;
}
public E getEntity() {
return this.entity;
}
#Transactional
public boolean persist(E transientInstance) {
try {
sessionFactory.getCurrentSession().persist(transientInstance);
return true;
} catch (RuntimeException re) {
return false;
}
}
#Transactional
public boolean remove(E transientInstance) {
try {
sessionFactory.getCurrentSession().delete(transientInstance);
return true;
} catch (RuntimeException re) {
return false;
}
}
#Transactional
public boolean merge(E detachedInstance) {
try {
sessionFactory.getCurrentSession().merge(detachedInstance);
return true;
} catch (RuntimeException re) {
return false;
}
}
#SuppressWarnings("unchecked")
#Transactional
public E findById(int id) {
try {
E instance = (E) sessionFactory.getCurrentSession().get(entity.getClass(), id);
return instance;
} catch (RuntimeException re) {
return null;
}
}
#SuppressWarnings("unchecked")
#Transactional
public E findByField(String field, String value) {
try {
String expressao = entity.toString();
String nome_classe = new String();
StringTokenizer st = new StringTokenizer(expressao);
while (st.hasMoreTokens()) {
nome_classe = st.nextToken();
}
String query = "from "+nome_classe+" where "+field+" = :data";
Query q = sessionFactory.getCurrentSession().createQuery(query);
q.setParameter("data", value);
E instance = (E) q.uniqueResult();
return instance;
} catch (RuntimeException re) {
return null;
}
}
#SuppressWarnings("unchecked")
#Transactional
public List<E> findAll() {
try {
List<E> instance = sessionFactory.getCurrentSession().createCriteria(entity.getClass()).list();
return instance;
} catch (RuntimeException re) {
return null;
}
}
}
But, when I need retrieve a list of all items from the table, I am receiving 0 items. The method for do this is placed in my class UsuarioService:
#Transactional
public List<Usuario> listagem_usuarios() {
return usuario.findAll();
}
where I autowires my Dao class:
#Autowired
private UsuarioHome usuario;
#Autowired
private GrupoPermissaoHome grupo_permissao;
Anyone can tell what I am doing wrong here? I tested this solution in other projects (simpler than that), and it work.
UPDATE
When I try run the application, I am facing a cast error, like this, by example, when this json page is opened:
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%# taglib prefix="json" uri="http://www.atg.com/taglibs/json" %>
<json:object>
<c:forEach var="item" items="${lista}">
<json:object name="usuario">
<json:property name="id" value="${item.id}"/>
<json:property name="login" value="${item.login}"/>
<json:property name="pnome" value="${item.first_name}"/>
<json:property name="unome" value="${item.last_name}"/>
<json:property name="email" value="${item.email}"/>
</json:object>
</c:forEach>
</json:object>
the console shows this error:

UPDATE 2
After more tests, I verify that when I use:
List<E> instance = sessionFactory.getCurrentSession().createCriteria(entity.getClass()).list();
I get an empty list. But when I use:
List<E> instance = (List<E>) sessionFactory.getCurrentSession().createSQLQuery("select * from usuario").list();
I get the data from database, but I can access them, due to an cast error (explained above in the first update)
ps.: the other methods, findById and findByField, are working fine.

Ok, I solve this issue following the sugestion from this topic:
Class derived from generic class don't get the correct type
the final code for the Dao template it's that:
public class Dao<E> {
private final Class<E> entity;
#Autowired
protected SessionFactory sessionFactory;
protected Session getCurrentSession(){
return sessionFactory.getCurrentSession();
}
/*public Dao(E entity) {
this.entity = entity;
}*/
public Dao(Class<E> classe) {
this.entity = classe;
}
/*public E getEntity() {
return this.entity;
}*/
#Transactional
public boolean persist(E transientInstance) {
sessionFactory.getCurrentSession().persist(transientInstance);
return true;
}
#Transactional
public boolean remove(E transientInstance) {
sessionFactory.getCurrentSession().delete(transientInstance);
return true;
}
#Transactional
public boolean merge(E detachedInstance) {
sessionFactory.getCurrentSession().merge(detachedInstance);
return true;
}
#Transactional
public E findById(int id) {
E instance = (E) sessionFactory.getCurrentSession().get(entity.getClass(), id);
return instance;
}
#Transactional
public E findByField(String field, String value) {
String expressao = entity.toString();
String nome_classe = new String();
StringTokenizer st = new StringTokenizer(expressao);
while (st.hasMoreTokens()) {
nome_classe = st.nextToken();
}
String query = "from "+nome_classe+" where "+field+" = :data";
Query q = sessionFactory.getCurrentSession().createQuery(query);
q.setParameter("data", value);
E instance = (E) q.uniqueResult();
return instance;
}
#Transactional
public List<E> findAll() {
return (List<E>) sessionFactory.getCurrentSession().createCriteria(entity).setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list();
}
}

Lazy Initialization with #Transactional

I´m getting a lazy initialization exception. A have a controller method with the annotation #Transactional, it invokes a service method ( it not has the #Transactional annotation), and finally inside that method I invoke another spring component (it checks if the user has the proper role).
In the project I used the #Transactional and i have no problems. But in this case i have the lazy initialization exception.
Am I missing something?
Here is the code:
and here is the method that is first executed. It has the #Transactional annotation
#Transactional
public CompanyForm edit(){
CompanyForm form = new CompanyForm();
Company company = companyService.findMainOne(getLoggedUser());
if (company != null) {
if (company != null)
modelMapper.map(company, form);
}
return form;
}
This is the method in a service where the code is called
#Autowired
private UserVisitorHasBussinessRole hasBussinessRole;
#Override
public Company findMainOne(User user) {
if (user == null)
throw new NullPointerException("the user can not be null");
user.accept(hasBussinessRole);
List<Company> companies = this.companyRepository.findOwnedBy(user
.getId());
if (companies != null && companies.size() > 0)
return companies.get(0);
return null;
}
This component checks if the user has the proper role. This is where i got the exception
#Component
public class UserVisitorHasBussinessRole implements UserVisitor {
#Autowired
private Messages messages;
#Override
public void visit(SystemUser user) {
if(user == null || user.getUserRoles() == null || user.getUserRoles().isEmpty())
{
String message = messages.get("hasBussinesRoleVisitor.noRole");
throw new RuntimeException(message);
}
Boolean hasRole = false;
for (UserRole role : user.getUserRoles()) {
if(role instanceof UserRoleBusiness){
hasRole = true;
break;
}
}
if(!hasRole)
{
String message = messages.get("hasBussinesRoleVisitor.noRole");
throw new RuntimeException(message);
}
}
#Override
public void visit(SocialUser user) {
String message = messages.get("hasBussinesRoleVisitor.noRole");
throw new RuntimeException(message);
}
}
This is where the exception is thrown
user.getUserRoles().isEmpty()
The entity:
#Entity
#DiscriminatorValue(value = "BU")
public class SystemUser extends User {
/**
*
*/
private static final long serialVersionUID = 3845147625976106863L;
// for joing the tables (many-to-many)
#ManyToMany(cascade = CascadeType.ALL, targetEntity = UserRole.class)
#JoinTable(name = "systemUser_userRole", joinColumns = { #JoinColumn(name = "system_user_id") }, inverseJoinColumns = { #JoinColumn(name = "role_Id") })
private List<UserRole> userRoles;
/**
* the list of user roles
* #return the user roles
*/
public List<UserRole> getUserRoles() {
return userRoles;
}
/***
* set the list of user roles
* #param userRoles the user roles
*/
public void setUserRoles(List<UserRole> userRoles) {
this.userRoles = userRoles;
}
}
I'm getting the following exception

I solved using #LazyCollection(LazyCollectionOption.FALSE)
here is the code:
#ManyToMany(cascade = CascadeType.ALL, targetEntity = UserRole.class)
#JoinTable(name = "systemUser_userRole", joinColumns = { #JoinColumn(name = "system_user_id") }, inverseJoinColumns = { #JoinColumn(name = "role_Id") })
#LazyCollection(LazyCollectionOption.FALSE)
private List<UserRole> userRoles;
It is not the best solution but it works. The problem is that LazyCollection annotation is a Hibernate annotation and not a jpa one.
Thanks to all

This happens when a lazy initialized object is read when the original transaction is already completed. In other words, when you return something from a method with #Transactional annotation all objects must be initialized (no way to access lazy objects after returning from the method). So use lazy="false" in this case to resolve the issue (or force lazy initialization inside the method).

Add #Transactional to findMainOne and visit(SystemUser) so they both participate in the same transaction, thus giving them access to the session/entity-manager for lazily-loading related components. Or you can load those components that might be needed before calling findMainOne.
