I tried to put all lib for spring and hibernate. I don't know what is the cause of the problem.

You have to adopt the property "packageToScan" in your spring-mvc-demo-servlet.xml. It should specify your entity package (com.attar.test.entity).

packagesToScan not working with AnnotationSessionFactoryBean

I am new to spring. I was trying to integrate spring with hibernate but
I am not able to get my entity class Employee using packagesToScan, before this I tried annnotatedClasses as well that too didn't work, I also tried wildcards (com.sfb.**.*) with packagesToScan but no luck yet. FYI I am using javax.persistence.Entity so not an import issue too. Below are my spring.xml file and other along with stacktrace:

Here is an error (Employee.java):
#OneToOne(fetch = FetchType.LAZY, mappedBy = "address", cascade =
CascadeType.ALL)
private Address address;
mappedBy attribute should only used for inverse size of association, so it is not applicable here.
I guess you are trying to build simple unidirectional association.
It should look something like:
#OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
#JoinColumn(name="ADDRESS_ID") /* this is the name of address id column in 'emp' table*/
private Address address;
Here is almost identical example from book.

I am going to be confused. I am trying to get Hibernate work with Spring, I can not get rid of a BeanCreationException. Please help me. I am new to Spring (and also Hibernate).
The problem is caused in a controller, having a private attribute userService which is annotated with #Autowired.
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'testController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.aerts.service.UserService com.aerts.controller.TestController.userService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.aerts.service.UserService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
I am really confused, please help me somebody.
Here is my root-context.xml:

My UserDaoImpl:
package com.aerts.dao;
import java.util.ArrayList;
import java.util.List;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import com.aerts.domain.User;
#Service
public class UserDaoImpl implements UserDao{
#Autowired
private SessionFactory sessionFactory;
#Override
public void addUser(User user) {
sessionFactory.getCurrentSession().save(user);
}
#Override
public List<User> listUser() {

.list();

User.class, id);
if (user != null) {
sessionFactory.getCurrentSession().delete(user);
}
}
#Override
public void updateUser(User user) {
sessionFactory.getCurrentSession().update(user);
}
}
And my UserServiceImpl:
package com.aerts.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.aerts.dao.UserDao;
import com.aerts.domain.User;
#Service
public class UserServiceImpl implements UserService {
#Autowired
private UserDao userDao;
#Override
#Transactional
public void addUser(User user) {
userDao.addUser(user);
}
#Override
#Transactional
public List<User> listUser() {
return userDao.listUser();
}
#Override
#Transactional
public void removeUser(int id) {
userDao.removeUser(id);
}
#Override
#Transactional
public void updateUser(User user) {
userDao.updateUser(user);
}
}
I would really appreciate it if somebody could help me, i am going to be desperate...

Add the service class package to the component-scan base-package list in the application context file
<context:component-scan
base-package="
com.aerts.controller
com.aerts.service">
</context:component-scan>

I'm not expertise in spring but I assume that you have a problem with your service, if you use an interface you should inject ut and not your class...
see this track...
Spring expected at least 1 bean which qualifies as autowire candidate for this dependency

Product creation doesn't work (under Spring MVC with JPA)

Well, the code is working under the Test Enviroment, but not on the front context of the application. This is driving me crazy to be honest.
Here is the controller:
package org.admios.nuevoproyecto.controller;
import java.util.List;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.validation.BindingResult;
import org.admios.nuevoproyecto.dao.ProductDAO;
import org.admios.nuevoproyecto.model.Product;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.apache.log4j.Logger;
import org.springframework.web.bind.annotation.PathVariable;
import static java.lang.System.out;
#Controller
#RequestMapping("/product")
public class ProductController {
private static Logger logger = Logger.getLogger(ProductController.class);
#Autowired
ProductDAO pdi;
#InitBinder
public void setAllowedFields(WebDataBinder dataBinder) {
dataBinder.setDisallowedFields("id");
}
#RequestMapping(value="/list")
public void listAllProducts() {
List<Product> products = pdi.getProducts();
for (Product product : products) {
System.out.println("Title: " + product.getTitle());
System.out.println("Description: " + product.getDescription());
System.out.println("Price: " + product.getPrice());
System.out.println("--------");
}
}
#RequestMapping(value="/add", method=RequestMethod.POST)
public String addProduct(#ModelAttribute Product product, BindingResult result) {
logger.info("Entrando en el metodo para agregar nuevo producto");
// Product newProduct = new Product();
// newProduct.setTitle("Titulo del producto2s");
// newProduct.setDescription("Descripcion del producto");
// newProduct.setPrice(220f);
System.out.println(product.getPrice());
Product savedProduct = pdi.saveProduct(product);
System.out.println(savedProduct.getId());
return "hello";
}
#RequestMapping(value="/form")
public String viewForm() {
out.println("entering viewForm()");
return "addproduct";
}
#RequestMapping(value="/view/{id}", method=RequestMethod.GET)
public void viewProduct(#PathVariable("id") Long id) {
System.out.println(id);
}
#ModelAttribute("product")
public Product getProductObject() {
out.println("entering getProductObject()");
return new Product();
}
}
The DAO implementation:
package org.admios.nuevoproyecto.dao;
import java.util.List;
import javax.persistence.EntityManagerFactory;
import org.admios.nuevoproyecto.model.Product;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.jpa.support.JpaDaoSupport;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
#Repository
public class ProductDaoImp extends JpaDaoSupport implements ProductDAO {
private static Logger log = Logger.getLogger(ProductDaoImp.class);
#Autowired
public ProductDaoImp(EntityManagerFactory entityManagerFactory) {
super.setEntityManagerFactory(entityManagerFactory);
}
#Override
public List<Product> getProducts() {
return getJpaTemplate().find("select p from Product p");
}
#Override
#Transactional(propagation = Propagation.REQUIRED, readOnly = false)
public Product saveProduct(Product product) {
log.info("Trying to create a new product");
Product newProduct = getJpaTemplate().merge(product);
log.info(newProduct.getDescription());
log.info(newProduct.getTitle());
log.info(newProduct.getId());
log.info(newProduct.getPrice());
return newProduct;
}
#Override
public void removeProduct(Product product) {
getJpaTemplate().remove(product);
}
#Override
public Product getProductById(Integer id) {
return getJpaTemplate().find(Product.class, id);
}
}
The applicationContext looks like this:
http://pastie.org/1175350

1.Create transaction manager as follow :
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" >
<property name="persistenceUnitName" value="persistanceUnit"/>
<property name="dataSource" ref="dataSource"/>
<property name="persistenceXmlLocation" value="classpath:persistence.xml"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="${db.orm.showsql}" />
<property name="generateDdl" value="${db.orm.generateDdl}" />
<property name="database" value="${db.type}"/>
<property name="databasePlatform" value="${db.orm.dialect}" />
</bean>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
2.use persistance.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="persistanceUnit" transaction-type="RESOURCE_LOCAL">
<description>Oracle db Persistence Unit</description>
<class>com.company.YourModelClass</class>
<properties/>
</persistence-unit>
</persistence>
3.Add following annotation in applicationContext.xml
<context:component-scan base-package="com.yourcompany.basepackage" />
4.annoatate your Entitymanager in service class like:
#PersistenceContext
private EntityManager em = null;
5.Inject TrasnsactionManager to :
private PlatformTransactionManager platformTransactionManager = null;
6.persist object like:
platformTransactionManager .persist(obj);

Have you tried with getJpaTemplate().persist(Object)?
