Unable to locate persister : org.ceri.gestiondonnees.entities.Utilisateur

I'm getting the error below but I don't know what is the problem. My entity is correctly written and the associated table exist also on database.
This is my entity
package org.ceri.gestiondonnees.entities;
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
#Entity
public class Utilisateur implements Serializable{
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private int id ;
private String email ;
private String nom ;
private String prenom ;
private String password ;
public Utilisateur() {
super();
// TODO Auto-generated constructor stub
}
public Utilisateur(String nom, String prenom, String email, String password)
{
super();
this.nom = nom;
this.prenom = prenom;
this.email = email;
this.password = password;
}
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public String getPrenom() {
return prenom;
}
public void setPrenom(String prenom) {
this.prenom = prenom;
}
public String getEmail() {
return email;
}
Here is a the method of my spring's controller where I'm invoking the business layer
#RequestMapping(value = "/signin")
public String logIn(UserForm userForm, Model model) {
Utilisateur user = metier.getUser(1) ;
return "home";
}
The business method
#Override
public Utilisateur getUser(int idUser) {
// TODO Auto-generated method stub
Utilisateur user = em.find(Utilisateur.class, idUser);
return user;
}
This is the exception that I got

JPA TransactionRequiredException

I am new to Spring and JPA I am having an issue with a TransactionRequiredException. I tried the tips located here, here and here (such as annotating with #Transactional, starting transactions manually etc.)
My code is as follows:
Goal.java
#Entity
#Table(name = "goals")
public class Goal
{
#Id
#GeneratedValue
#Column(name = "GOAL_ID")
private Long id;
#Range(min = 1, max = 120)
#Column(name = "MINUTES")
private int minutes;
public int getMinutes()
{
return minutes;
}
public void setMinutes(int minutes)
{
this.minutes = minutes;
}
public Long getId()
{
return id;
}
public void setId(Long id)
{
this.id = id;
}
}
GoalRepositoryImpl.java
#Repository("goalRepository")
#Transactional
public class GoalRepositoryImpl implements IGoalRepository
{
#PersistenceContext
private EntityManager em;
public Goal save(Goal goal)
{
em.persist(goal);
return goal;
}
}
GoalServiceImpl.java
#Service("goalService")
public class GoalServiceImpl implements IGoalService
{
#Autowired
private IGoalRepository goalRepository;
#Transactional
public Goal save(Goal goal)
{
return goalRepository.save(goal);
}
}
GoalController
#Controller
#SessionAttributes("goal")
public class GoalController
{
#Autowired
private IGoalService goalService;
#RequestMapping(value = "/addGoal", method = RequestMethod.POST)
public String updateGoal(#Valid #ModelAttribute("goal") Goal goal, BindingResult result){
if (result.hasErrors()){
return "addGoal";
}else{
goalService.save(goal);
}
return "redirect:addMinutes.html";
}

There are things i cannot see from your project, so i cannot be sure
include spring.tx in your pom or add the library whichever way you are doing it
#Configuration #EnableTransactionManagement
without these two steps you cannot start or commit a transaction.

Hibernate 5: Mapping by annotation doesn't work and throws MappingException (unknown entity)

I have already checked solutions for the problem, but it did not help.
I am practicing Spring+Hibernate. Previously I have mapped entities by .xml file. But now I tried to do it by annotations cause it looks more comfortable. But unfortunately, I got
Unknown entity: milkiv.easyword.models.UserRole; nested exception is org.hibernate.MappingException: Unknown entity: milkiv.easyword.models.UserRole
So I have the next model file:
package milkiv.easyword.models;
import java.io.Serializable;
import java.util.Objects;
import javax.persistence.*;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.NotBlank;
#Entity (name = "UserRole")
#Table(name = "user_role")
public class UserRole implements Serializable{
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
#Column(name = "role_id", updatable = false, unique = true)
private int roleId;
#NotBlank(message = "Email field can not be empty or missed.")
#Size(min = 3, max = 59, message = "Email field must have from 5 to 128 symbols.")
#Column(name = "name", nullable = false, unique = true)
private String name;
public UserRole() {
}
public int getRoleId() {
return roleId;
}
public void setRoleId(int roleId) {
this.roleId = roleId;
}
public String getName() {
return name;
}
public void setName(String name) {
//INFO: SPRING REQUIRE NAME ROLES IN FORMAT - ROLE_rolename
this.name = "ROLE_".concat(name);
}
#Override
public int hashCode() {
return (name.hashCode()*31+roleId)*31;
}
#Override
public boolean equals(Object obj) {
if (this == obj) {
return true;
}
if (obj == null) {
return false;
}
if (getClass() != obj.getClass()) {
return false;
}
final UserRole other = (UserRole) obj;
if (this.roleId != other.roleId) {
return false;
}
return Objects.equals(this.name, other.name);
}
}

The message is clear, but the cause of it - no.
Please if anyone have any ideas can you help me? I will appreciate any help.
Thank's in advance.
EDIT: I use Hibernate 5.0.1.Final version.
EDIT: Tried this one. Also doesn't work for me:
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="annotatedClasses">
<list>
<value>milkiv.easyword.models</value>
</list>
</property>
<property name="configLocations">
<value>classpath:resources/hibernate.cfg.xml</value>
</property>
</bean>

Hibernate does not know about your annotated class, you need to tell hibernate where it is, with this property in the session factory xml:
<mapping package="milkiv.easyword.models"/>
or directly a class:
<mapping class="milkiv.easyword.models.UserRole"/>
Check out the docs.

javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCExcep tion: could not execute query

Hi I have researched this in these forums thoroughly and many people have posted stuff but none of that helps me.
my object:
#Entity
#Table(name = "ADDRESS")
#NamedQuery(name = "Address.findByRegistrationId", query = "SELECT a FROM Address a WHERE a.registration_id = :registration_id")
public class Address {
#Id
#Column(name = "ADDRESS_ID")
#GeneratedValue(strategy = GenerationType.AUTO)
private long address_id;
#Column(name = "REGISTRATION_ID")
private long registration_id;
public long getRegistration_id() {
return registration_id;
}
public void setRegistration_id(long registration_id) {
this.registration_id = registration_id;
}
my repository implementation:
#Repository
public class AddressRepositoryJpa implements AddressRepository {
private final Logger log = Logger.getLogger(AddressRepositoryJpa.class.getName());
#PersistenceContext
private EntityManager entityManager;
#Override
public Address findByID(int id) {
return entityManager.find(Address.class, id);
}
#Override
public Address findByRegistrationID(Long registration_id) {
TypedQuery<Address> query = (TypedQuery<Address>) entityManager.createNamedQuery("Address.findByRegistrationId", Address.class);
query.setParameter("registration_id", registration_id);
Address address = (Address) query.getSingleResult();
return address;
}
my persistence.xml
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
<property name="username" value="xxxx"/>
<property name="password" value="xxxxx"/>
<property name="url" value="jdbc:oracle:thin:#//xxxxx:1521/XXX.XXX.XXX.XX.XX"/>
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
</property>
<property name="jpaProperties">
<map><!--validate | update | create | create-drop-->
<entry key="hibernate.hbm2ddl.auto" value="update"/>
<entry key="hibernate.show_sql" value="true"/>
<entry key="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
</map>
</property>
<property name="packagesToScan" value="edu.rmit.core.entities"/>
</bean>
<tx:annotation-driven/>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"/>
I have tried named queries and even one without parameters as a list and no luck, I wonder if there is any special configuration I need to do.
The entitymanager.find method works, so the connection to the db is fine.
Thanks a lot.

I have found what the problem was, in my entity I had another field called "student_id" that was defined in the entity as int but in the database is a varchar.
So the errors given where not related to the field I was focusing on: "registration_id" but to another one.
Thanks everyone for your answers.

Maybe it's just a matter of improper casing :)
Named Parameters in Queries
Named parameters are case-sensitive and may be used by both dynamic and static queries.
You can easily test it out by using this API instead
javax.persistence.Query#setParameter(int, java.lang.Object) like so:
Query query = entityManager.createNamedQuery("find address by registration_id");
query.setParameter(1, registration_id);
Address address = (Address) query.getSingleResult();
return address;

try naming your query like this:
#NamedQuery(name = "Address.findByRegistrationId")...

Can anyone suggest me what I am doing wrong here?

If the table really, really, does exist in mySQL, and your using Linux/Unix, and the error shows the table name in all wrong/upper-case, then the issue is that table names in MySQL are case sensitive and hibernate is upper casing them. I'm using hibernate 4.3.
I just had this issue. Explanation here: lower_case_table_names=1
--edit-- In retrospect, it's probably better to find and change any #Table or hbm.xml references to match the database. I ran a wizard that generated an hbm.xml with uppercase names -- didn't realize that it was in my project until just now. I'll leave this here to make people aware of the case sensitivity.
--end of edit--
Here is how I fixed it:
Drop the database.
Add this to /etc/mysql/my.conf:
set lower_case_table_names=1 #(default value '0').
Restart mysqld.
Recreate the Database.
optional? Change to lowercase all table names in annotations/hbm.xml.

Hibernate won't automatically generate your database schema for you. You have to tell it to do so with a special hibernate property:
hibernate.hbm2ddl.auto
With value update or create based on what you want. See here and the related chapters.
In Spring, the configuration goes
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${jdbc.dialect}</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
