LazyInitializationException with SpringOpenEntityManagerInViewFilter - spring

Despite I'm using SpringOpenEntityManagerInViewFilter, I'm getting LazyInitializationException after to get some results.
The mystery is why I'm getting the first results (rows) right and then it gets tired and I don't get more results.
I've try everything I've read here I've almost read all the post here, I'm still stuck here.
I'm newbie with Spring data jpa, I suspect it could be a nonsense

I've solved using a Primefaces Lazy datatable
The problem seems to be that once the page is rendered the hibernate session gets closed.
Service, repository and manageBean have chaged a bit
Service:
#Component
public class PoSrvc implements IPoSrvc {
#Autowired
private IPoBuRepository poBuRepository;
#Override
#Transactional
public List<Po> getAllByBu(long buId, int page, int results, String sort, SortOrder sortOrder) {
Pageable pageable = new PageRequest(
page, results,new Sort(new Order(SortOrder.ASCENDING.equals(sortOrder)? Direction.ASC: Direction.DESC, "po."+sort))
);
return poBuRepository.findPoByBuId(buId,pageable);
}
#Override
public int getCountAllByBu(long buId) {
return poBuRepository.findCountAllByBuId(buId);
}
Repository:
public interface IPoBuRepository extends JpaRepository<PoBu, Long> {
#Query("SELECT DISTINCT po FROM PoBu pb WHERE (pb.bu.id=:id OR pb.po.creatorBu.id=:id) AND pb.po.deleted=false")
List<Po> findPoByBuId(#Param("id") long id,Pageable pageable);
#Query("SELECT COUNT (DISTINCT pb.po) FROM PoBu pb WHERE (pb.bu.id=:id OR pb.po.creatorBu.id=:id) AND pb.po.deleted=false")
int findCountAllByBuId(#Param("id") long id);
And my managedBean:
#ManagedBean
#ViewScoped
public class ManagePO implements Serializable {
private static final long serialVersionUID = 8947292155668339391L;
#ManagedProperty(value="#{appContext}")
private AppContext appcontext;
#ManagedProperty("#{poSrvc}")
private IPoSrvc poSrvc;
private LazyDataModel<Po> lazyModel;
#PostConstruct
public void init(){
this.readOnly=false;
this.lazyModel = new LazyPoDataModel(appcontext.getBuId(), poSrvc);
Finally this the Lazy table model:
public class LazyPoDataModel extends LazyDataModel<Po> {
private static final long serialVersionUID = 1L;
private long buId;
private IPoSrvc poSrvc;
public LazyPoDataModel(long buId, IPoSrvc poSrvc) {
super();
this.buId = buId;
this.poSrvc = poSrvc;
this.setRowCount(this.poSrvc.getCountAllByBu(buId));
}
#Override
public List<Po> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String,Object> filters) {
List<Po> data = new LinkedList<Po>();
int page = first/pageSize;
if(sortField==null){
sortField = "ref";
}
data=poSrvc.getAllByBu(buId, page, pageSize, sortField, sortOrder);
return data;
}
Now no LazyInitializationException is thrown anymore!!!
Thanks for clues!

LazyInitializationException for some of requests

This is probably a duplicate, but I am struggling with this problem for few days now. After dozens of tutorials, books, stack answers etc I am in the dead end.
This is RESTfull Spring hibernate app
How to eliminate lazyinitializationexception and problems with Session? I tried to set eager fetch in model class, but it didn't work for me, I have Transaction annotations but its still the same. I bet that it must be set somehow in Spring xml config, but have no clue how to do that.
Why ... /getAllCountries works perfectly fine, and /getCountry/id throw Session error? I see no difference between them.
Please give me a code based answer.
Controller:
#RestController
public class CountryController {
#Autowired
CountryService countryService;
#RequestMapping(value = "/getAllCountries", method = RequestMethod.GET, headers = "Accept=application/json")
public List<Country> getCountries() {
List<Country> listOfCountries = countryService.getAllCountries();
return listOfCountries;
}
#RequestMapping(value = "/getCountry/{id}", method = RequestMethod.GET, headers = "Accept=application/json")
public Country getCountryById(#PathVariable int id) {
return countryService.getCountry(id);
}
// .....
}
DAO:
#Repository
public class CountryDAO {
#Autowired
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sf) {
this.sessionFactory = sf;
}
public List<Country> getAllCountries() {
Session session = this.sessionFactory.getCurrentSession();
List<Country> countryList = session.createQuery("from Country").list();
return countryList;
}
public Country getCountry(int id) {
Session session = this.sessionFactory.getCurrentSession();
Country country = (Country) session.load(Country.class, new Integer(id));
return country;
}
// ......
}
Service:
#Service("countryService")
public class CountryService {
#Autowired
CountryDAO countryDao;
#Transactional
public List<Country> getAllCountries() {
return countryDao.getAllCountries();
}
#Transactional
public Country getCountry(int id) {
return countryDao.getCountry(id);
}
}
Entity:
#Entity
#Table(name="COUNTRY")
public class Country{
#Id
#Column(name="id")
#GeneratedValue(strategy=GenerationType.IDENTITY)
int id;
#Column(name="countryName")
String countryName;
#Column(name="population")
long population;
public Country() {
super();
}
public Country(int i, String countryName,long population) {
super();
this.id = i;
this.countryName = countryName;
this.population=population;
}
// getters and setters...
}

Your problem comes from the Session.load() method that doesn't return an object but a proxy of the object which is initialized at the first access of an non-identifier property.
Hibernate Documentation:
T load(Class theClass,
Serializable id)
Return the persistent instance of the given entity class with the given identifier, assuming that the
instance exists. This method might return a proxied instance that is
initialized on-demand, when a non-identifier method is accessed.
And for you it means it's initialized when Spring will try to marshall the object, which is when the Session is close.
To fix it you can either add #org.hibernate.annotations.Proxy(lazy = false) on the class level, use Session.get() instead of Session.load() in the dao to get a fully loaded object (depending on the lazy strategy on members).
Or manually trigger the lazy loading when the Session is still like by calling any member of the object (like calling List.size() on a collection to force the loading).

The answer is there in the stack trace:
Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [br.inf.datus.ifisio.service.TipoSanguineoServiceImpl]: No default constructor found;
You have specified field injection in that class (#Autowired annotation on field tipoSanguineoDao) but you provided no default (no-argument) constructor. It appears that you want constructor injection (evidenced by the fact that you have a #Qualifier annotation on the constructor argument), but that conflicts with field injection.
Move the #Autowired annotation to the constructor.
Looks like you are trying to do constructor based dependency injection..
Below change in TipoSanguineoServiceImpl should correct your problem.
#Autowired
public TipoSanguineoServiceImpl(#Qualifier("tipoSanguineoDaoImpl") GenericDao<TipoSanguineo, Long> genericDao) {
super(genericDao);
this.tipoSanguineoDao = (TipoSanguineoDao) genericDao;

java.lang.reflect.InvocationTargetException in sample Struts2 spring4.1 jpa/hibernate3.1.6

I'm trying to develop a basic application with didactic purposes, using Struts 2 + Spring 4.1 + JPA / Hibernate 3.6 with Netbeans 8 as IDE. I managed to create and update users without problem but when I try to login I get java.lang.reflect.InvocationTargetException, specifically in this instruction:
Query query = entityManager.createQuery(
"from User where username = :username")
.setParameter("username", username);
the database is created and contains a couple of records in each table.
I will appreciate greatly any help on why this is happening to me.

Thanks to Andrea Ligios comment I understood better what was the real exception and was already settled in another question. Sorry I doubled the question.
I had two versions of the library "antlr" simply remove the struts antlr lib and use only antlr of hibernate.
Thanks to all users for their comments.

Initialization of collection throws LazyInitializationException

I have a problem with the access to a collection from JSP file. Application is based on MVC Spring framework. I put OpenSessionInViewFilter filter to my web.xml. When I want to access to URL with mentioned file, it throws me
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.app.cloud.hibernate.Product.availabilities, no session or session was closed
I use domain driven design in my app. When I changed fetch type in class Product from FetchType.LAZY to FetchType.EAGER, it worked.
stacktrace

It's very classical error when working with Hibernate.
If you have any lazy-loading proxies your should replace them either with nulls or with real objects before returning from #Transactional context.
The Set or List that is lazy loaded is replaced by the Hibernate with the proxy. The proxy would load the collection first time it is accessed. But what if it is first accessed if you are outside the transactional context? The hibernate session that is referenced by the proxy doesn't exist so you have the error.
If you won't need the collection, set it to null or empty HashSet/ArrayList. If you would need it, call the size() or iterate through the element within transactional context. If you are not sure, provide the API for loading the connection. But don't return objects with uninitialized proxies.
Annotate your Controller as #Transactional. You wont see that error again, You bet!!
Note
Experts say that #Transactional is not to be used on Controller, But I didn't get an answer why?
You can try
#Proxy (lazy = false)
On top of both entity class. It works in my case.

NPE when invoking getter of managed property

I am learning Spring with Hibernate and am creating a movie rental application using JSF as front end framework.
I have an application scoped managed property in my registration bean which is view scoped. In the register() method to insert the user details in the database, I invoke the service locator implementation bean to get a reference to the required service implementation. However, I get an NPE when I invoke the getter of the service locator property.
Following are my managed beans...
Registration Bean
#ManagedBean
#ViewScoped
public class RegistrationBean extends BaseBean implements Serializable
{
private static final long serialVersionUID = -6449858513581500971L;
private String userID;
private String password;
private String firstName;
private String lastName;
private String email;
private String addressLine1;
private String addressLine2;
private String city;
private String state;
private String pincode;
public RegistrationBean() {
super();
}
// getter / setters...
public String register()
{
String nextPage = null;
try {
RegistrationDetails userDetails = ModelBuilder.populateRegistrationData(this);
// NPE at this line. getServiceLocator() returns null
int registrationID = getServiceLocator().getUserService().registerUser(userDetails);
nextPage = "success";
}
catch (RegistrationException e) {
LOGGER.error(e.getMessage());
}
return nextPage;
}
}
Base Bean
public class BaseBean
{
#ManagedProperty("#{serviceLocator}")
protected IServiceLocator serviceLocator;
protected IServiceLocator getServiceLocator() {
return serviceLocator;
}
public void setServiceLocator(IServiceLocator serviceLocator) {
this.serviceLocator = serviceLocator;
}
}
Service Locator Bean
#ManagedBean
#ApplicationScoped
public class ServiceLocator implements IServiceLocator
{
private static final String USER_SERVICE = "userService";
public ServiceLocator() {
super();
final ServletContext sc = FacesUtils.getServletContext();
this.webAppContext = WebApplicationContextUtils.getRequiredWebApplicationContext(sc);
this.userService = (IUserService) webAppContext.getBean(USER_SERVICE);
}
private ApplicationContext webAppContext;
private IUserService userService;
#Override
public IUserService getUserService() {
return userService;
}
public ApplicationContext getWebAppContext() {
return webAppContext;
}
}
And here is the stacktrace as seen in my Eclipse console

I am using
JSF 2.1 (Mojarra)
Hibernate 4.1
Spring 3.2
Tomcat 7

Could someone please point out if I have missed something??

This post helped me to make the code work : http://www.javacodegeeks.com/2012/04/jsf-2-primefaces-3-spring-3-hibernate-4.html
However, the code does not work if I keep the Registration Bean as view scoped. Can anyone please help me figure out the reason for the same?
UPDATE: Found the solution for the ViewScope issue : http://blog.harezmi.com.tr/spring-view-scope-for-jsf-2-users/
