Spring with Hibernate JPA - runtime errors

I'm trying to develop a simple web application using Spring and Hibernate JPA on Glassfish 4.1.1 server.
I have an entity class:
package entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "USERS")
public class User {
#Id
#GeneratedValue
#Column(name = "ID")
private long id;
private String firstName;
private String lastName;
private String email;
private String login;
private String password;
public User() {
}
public User(long id, String firstName, String lastName, String email, String login, String password) {
this.id = id;
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
this.login = login;
this.password = password;
}
getters and setters...
}
Then controller class:
package controller;
import ...
#Controller
public class LoginController {
#Autowired
private UserService userService;
#RequestMapping(value = "/login", method = RequestMethod.POST)
public ModelAndView executeLogin(HttpServletRequest request, HttpServletResponse response, #ModelAttribute("user") User user) {
userService.addUser(new User(20, "a", "b", "dgsd", "sfadf", "sdfsdf"));
}
}
UserService:
package service;
import dao.UserDao;
import entity.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
#Service
public class UserService {
#Autowired
UserDao userDao;
public void addUser(User user) {
userDao.insert(user);
}
}
UserDao:
package dao;
import entity.User;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.springframework.stereotype.Repository;
#Repository("userDao")
public class UserDao {
#PersistenceContext
private EntityManager entityManager;
public void insert(User user) {
entityManager.persist(user);
}
}

What am I doing wrong? Thanks for helping!

Your code attempts to create a JTA-capable entity-manager, because you configured your persistence unit to be JTA-enabled:
<persistence-unit name="LibraryPU" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:app/library</jta-data-source>
</persistence-unit>
But JTA-capable EMs are normally not to be created by webapps.
If you are really aiming for a simple webapp, you should most likely go for a simple persistence-unit. If you follow the link above (Chapter: Valid RESOURCE_LOCAL Unit usage) you will see what is the difference. A simple configuration could look like this for example:
<persistence>
<persistence-unit name="manager1" transaction-type="RESOURCE_LOCAL">
<class>org.hibernate.ejb.test.Cat</class>
<class>org.hibernate.ejb.test.Distributor</class>
<class>org.hibernate.ejb.test.Item</class>
<properties>
<property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver"/>
<property name="javax.persistence.jdbc.user" value="sa"/>
<property name="javax.persistence.jdbc.password" value=""/>
<property name="javax.persistence.jdbc.url" value="jdbc:hsqldb:."/>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/
<property name="hibernate.max_fetch_depth" value="3"/>
<!-- cache configuration -->
<property name="hibernate.ejb.classcache.org.hibernate.ejb.test.Item" value="read-write"/>
<property name="hibernate.ejb.collectioncache.org.hibernate.ejb.test.Item.distributors" value="read-write, RegionName"/>
<!-- alternatively to <class> and <property> declarations, you can use a regular hibernate.cfg.xml file -->
<!-- property name="hibernate.ejb.cfgfile" value="/org/hibernate/ejb/test/hibernate.cfg.xml"/ -->
</properties>
</persistence-unit>
</persistence>

Your exception shows a NullPointerException on line 47 of BetController. However there is nothing at this line in the class you posted. My guess is that your UserService is not injected in your controller. Add the #Autowired annotation:
#Controller
public class BetController {
#Autowired
UserService service;

I think you miss autowire Userservice object in to controller layer
Please add #autowire top of Userservice object It will sovles your problem.
#Autowire
UserService service;
If its give any problem just google how to autowire service object,
Also you have done one mistake while creating service object you need to create Userservice as Interface and one concert implementation of Userservice like UserServiceImpl
Thanks,
Himanshu

Put #Service annotation on UserService class,and #Autowired on the below line in BetController class.
#Autowired
UserService service;
And i see you setted component scanning to controller package only,how ever you need to set it to below.
<context:component-scan base-package="org.proffart.bet.*"/>

This is the best example for Spring mvc crud operation using JQuery Ajax. You may find maven as well in this.

The naive solution for non-JSF developers would be to simply initialize the variables inside the getter to resolve the null value in the attributes. This is:
public List getListeAnnees() {
listeAnnees = getAnneeMetier().getAllAnnees();
return listeAnnees;
}
public AnneeMetier getAnneeMetier() {
if (anneeMetier == null) {
anneeMetier = new AnneeMetierImpl();
}
return anneeMetier;
}
But this may generate lot of overhead from server in case AnneeMetier#getAllAnnees() retrieves the data from database. This is explained here: Why JSF calls getters multiple times
To solve this, you do two things:
Define the right scope of your bean.
Initialize the necessary data for work using #PostConstruct annotated method.
And this would result in:
Defining the scope as #ViewScoped (explained in the link above).
Initializing listeAnnees in #PostConstruct method.
Remove any business logic from getters/setters
So the code would look like this:
#ManagedBean
#ViewScoped
public class AnneeBean {
private AnneeMetier anneeMetier;
private List<Annee> listeAnnees;
#PostConstruct
public void init() {
anneeMetier = new AnneeMetierImpl();
listeAnnees = anneeMetier.getAllAnnees();
}
public List getListeAnnees() {
return listeAnnees;
}
public void setListeAnnees(List listeAnnees) {
this.listeAnnees = listeAnnees;
}
public AnneeMetier getAnneeMetier() {
return anneeMetier;
}
public void setAnneeMetier(AnneeMetier anneeMetier) {
this.anneeMetier = anneeMetier;
}
}
BUT since you're trying to integrate JSF with Spring, you have to take into account that Spring has not yet full support of JSF 2 #ViewScoped annotation. For this case, you have/need to implement it yourself. There are plenty examples on the net about this, and looks that the most popular is from Cagatay's. In this way, you'll be able to gain power from both sides. And your bean will look like this:
#Component
#Scope("view")
public class AnneeBean {
#Autowired
private AnneeMetier anneeMetier;
private List<Annee> listeAnnees;
#PostConstruct
public void init() {
listeAnnees = anneeMetier.getAllAnnees();
}
public List getListeAnnees() {
return listeAnnees;
}
public void setListeAnnees(List listeAnnees) {
this.listeAnnees = listeAnnees;
}
}
More info:
Bean properties are shared across different sessions
Since you're learning Spring, the best bet would be to enable component scan and use annotations to configure your spring beans. Do the following:
Remove any bean configuration in applicationContext.xml.
Add this configuration to enable bean scan annotations:
<!--
These will enable component scan by annotation configuration
rather than XML configuration. One per package
-->
<context:component-scan base-package="dao" />
<context:component-scan base-package="model.services" />
Or if all your classes are inside one root package.
<!--
Assuming there's a root package for your packages like this
<context:component-scan base-package="com.myproject.dao" />
<context:component-scan base-package="com.myproject.model.services" />
-->
<context:component-scan base-package="com.myproject" />
Start configuring your Spring managed beans by annotations:
#Repository
public class AnneeHibernateDao implements AnneeDao{
//...
}
#Service
public class AnneeMetierImpl implements AnneeMetier{
#Autowired
private AnneeDao anneeDao;
//...
}
Compile your project and run it.

You are using getListeAnnees where you intend to call a method of your private object called anneeMetier, which is not initialized yet. You initialize that object through your setAnneeMetier method, which is never initialized in your code, therefore it is null. You can solve your problem by doing one of the following:
You initialize anneeMetier by calling the setAnneeMetier before you use getListeAnnees
You implement a constructor for your AnneeBean class where you initialize anneeMetier
You modify your getter (getListeAnnees) to be such as follows:
public List getListeAnnees() {
if (anneeMetier == null) {
return new ArrayList<Annee>();
}
listeAnnees = anneeMetier.getAllAnnees();
return listeAnnees;
}
EDIT: pL4GU33's comment might be useful, so I add his comment's idea to the answer:
public List getListeAnnees() {
if (anneeMetier == null) {
return Collections.emptyList();
}
listeAnnees = anneeMetier.getAllAnnees();
return listeAnnees;
}
His solution is more type-agnostic, so I upvote his comment.

what to write in applicationContext.xml in order to get hibernate session in filter

I need to initialize hibernate session in Filter for spring mvc, I know I need to add ContextListner in web.xml but I have no Idea of what to write in applicationContext.xml file.please guide to some tutorial or example ...
detailed explaination: I need to prepopulate my form using spring form tag, for that I need HibernateSession open in jsp lifecycle execution. I created a HibernateSessionFilter to enable hibernate session in jsp. Now again for that I need to initialize my hibernate session. see the
sf = //don't know what to write ;
in code below. I dont know how I can get hibernate sessionFactory there. I know it can be done via applicationContext.xml but can't get to the exact configuration needed.

I have found one major bug in your code and one minor.
The major bug is that you have configured TWO Hibernate Session Factories (this cases the stange exception) on in applicationContext.xml (correct) and on in spring-servlet.xml (this must be removed). (some more details as comment in the xml)
The updated spring-servlet.xml

ONLY one session factory per application!!
You have configured them already in applicationContext.xml
Spring mvc application have two spring contexts, an other and an inner context.
The inner context is created by ContextLoaderListener and in your case it is described in applicationContext.xml.
The outer context is created by DispatcherServelet and in your case it is described in spring-servlet.xml.
Filters can access only the inner context, therefore the OpenSessionInViewFilter requires that the inner context contain all the hibernate stuff
The outer context can beans access the inner context.
The outer context has access to all the web stuff (not like the inner context) therefore the #Controller Beans can be only instanceated in the outer context.

The minor bug ins in your contact_edit.jsp
Instead of <form:form method="post" action="add.html" commandName="contact"> use:
<c:url var="updateUrl" value="/doedit/${contact.id}"/>
<form:form method="post" action="${updateUrl}" commandName="contact">
And after this modification of your editContact I was able to modify the first name
/**
* This is only prove that it works.
* You should not update the contact directly in the controller (this is only a shortcut in for the example).
* If you load and update the contact in an method that is #Transactional, than you can remove the #Transactional from this
* controller method.
*/
#Transactional
#RequestMapping(value = "/doedit/{contactId}", method = RequestMethod.POST)
public String editContact(#PathVariable("contactId") final Integer contactId, final Contact editedContact) {
//contactService.editContact(contactId);
Contact contact = contactService.getContact(contactId);
contact.setFirstname(editedContact.getFirstname()); //only first name for the example
return "redirect:/index";
}
