org.hibernate.AnnotationException: No identifier specified for entity: springmvc.miniproject.entity.Review
Looks like you are missing #Id annotation on Review entity
I created a many to one relationship between my tables Person and adress it appears to be created given my ER diagram. But it's not making anything happen in my datasource, no join no
Is there a way to make this happen or is it supposed to be like that for Intellij? Seems to be easy to do with Eclipse.
This is my code for both entities and anything I think is relevant, don't hesitate to ask if you need anything.
#Entity
#Table(name = "personne", schema = "bddpersistence")
#IdClass(PersonneEntityPK.class)
public class PersonneEntity {
private int idPersonne;
private String nom;
private String prenom;
private String email;
private String tel;
private Integer age;
private Integer idAdress;
#OneToMany(mappedBy = "personne",cascade = CascadeType.ALL,orphanRemoval = true)
private List<AdressEntity> adress = new ArrayList<AdressEntity>();
#Entity
#Table(name = "adress", schema = "bddpersistence")
public class AdressEntity {
private String rue;
private Integer codePostal;
private String ville;
private int idAdress;
#ManyToOne
PersonneEntity personne;
package com.example;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import javax.persistence.*;
import java.sql.Timestamp;
public class TestHibernate {
static EntityManagerFactory emf;
static EntityManager em;
static EntityTransaction transaction;
public static void beginConnection(){
emf = Persistence.createEntityManagerFactory("NewPersistenceUnit");
em = emf.createEntityManager();
transaction = em.getTransaction();
transaction.begin();
}
public static void endConnection(){
transaction.commit();
em.close();
emf.close();
}
public static void insertAccount(String email, String name){
ComptesEntity compte = new ComptesEntity();
compte.setEmail(email);
compte.setNom(name);
em.persist(compte);
}
public static void createPerson (int id_personne,String nom,String prenom,int age,String email,String tel,String rue,String cp,String ville){
}
public static void insertPerson(String lastName, String firstName , String email, String tel , int age){

personne.setPrenom(firstName);
personne.setTel(tel);

personne.setAge(age);
em.persist(personne);
}
public static void main(String[] args) {
beginConnection();
endConnection();
}
}
Here is the persistence.xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</properties>
</persistence-unit>
</persistence>
And here is the hibernate config :
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

Lastly the composite PK for PersonEntity :
package com.example;
import javax.persistence.Column;
import javax.persistence.Id;
import java.io.Serializable;
import java.util.Objects;
public class PersonneEntityPK implements Serializable {
private int idPersonne;
private String email;
#Column(name = "id_personne")
#Id
public int getIdPersonne() {
return idPersonne;
}
public void setIdPersonne(int idPersonne) {
this.idPersonne = idPersonne;
}
#Column(name = "email")
#Id
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
PersonneEntityPK that = (PersonneEntityPK) o;
return idPersonne == that.idPersonne &&
Objects.equals(email, that.email);
}
#Override
public int hashCode() {
return Objects.hash(idPersonne, email);
}
}
I left out part of the code for entity that was just generated like the getters and setters.
I have an application that currently uses relational DBs but could later move on to NoSQL DBs. In this case, I am trying to build my POJOs in such a way that it could be used for both type of DBs (relational and NoSQL). I have the following entities as defined below.
Base class:
package net.breezeware.runway.idm.entity;
import java.io.Serializable;
public abstract class SpringDataUser implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
protected long id;
protected String firstName;
protected String lastName;
protected String middleInitial;
protected String email;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getMiddleInitial() {
return middleInitial;
}
public void setMiddleInitial(String middleInitial) {
this.middleInitial = middleInitial;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append("User ==> ");
sb.append("id = " + id + "; ");
sb.append("suemail = " + email + "; ");
sb.append("lastname = " + lastName + "; ");
sb.append("firstname = " + firstName + "; ");
sb.append("middleInitial = " + middleInitial);
return sb.toString();
}
}
JPA class:
package net.breezeware.runway.idm.entity.jpa;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.xml.bind.annotation.XmlRootElement;
import net.breezeware.runway.idm.entity.SpringDataUser;
#XmlRootElement
#Entity
#Table(name = "spring_data_user")
public class SpringDataUserJpa extends SpringDataUser {
/**

private static final long serialVersionUID = 1L;
#Override
#Id
public long getId() {
return id;
}
#Override
public void setId(long id) {
this.id = id;
}
#Column(name = "last_name")
#Override
public String getLastName() {
return lastName;
}
#Override
public void setLastName(String lastName) {

}
#Column(name = "email")

#Column(name = "middle_initial")
#Override
public String getMiddleInitial() {
return middleInitial;
}
#Override
public void setMiddleInitial(String middleInitial) {
this.middleInitial = middleInitial;
}
}
Mongo Class:
package net.breezeware.runway.idm.entity.mongo;
import net.breezeware.runway.idm.entity.SpringDataUser;
import org.springframework.data.mongodb.core.mapping.Document;
#Document(collection = "spring_data_users")
public class SpringDataUserMongo extends SpringDataUser {
/**

private static final long serialVersionUID = 1L;
#Override
public long getId() {
return id;
}
#Override
public void setId(long id) {
this.id = id;
}
#Override
public String getEmail() {
return email;
}
#Override
public void setEmail(String email) {
this.email = email;
}
#Override
public String getLastName() {
return lastName;
}
#Override
public void setLastName(String lastName) {
this.lastName = lastName;
}
#Override
public String getFirstName() {
return firstName;
}
#Override
public void setFirstName(String firstName) {
this.firstName = firstName;
}
#Override
public String getMiddleInitial() {
return middleInitial;
}
#Override
public void setMiddleInitial(String middleInitial) {
this.middleInitial = middleInitial;
}
}
I am planning to build a DAO to access records using these entities. I would like to define a generic DAO and then extend that for different storage types as shown below.
Generic DAO:
package net.breezeware.runway.idm.dao;
import java.util.List;
import org.springframework.data.repository.NoRepositoryBean;
import org.springframework.data.repository.PagingAndSortingRepository;
#NoRepositoryBean
public interface SpringDataUserRepository<SpringDataUser> extends PagingAndSortingRepository<SpringDataUser, Long> {
List<SpringDataUser> findByEmail(String email);
List<SpringDataUser> findByLastName(String lastName);
}
JPA DAO:
package net.breezeware.runway.idm.dao.jpa;
import net.breezeware.runway.idm.dao.SpringDataUserRepository;
import net.breezeware.runway.idm.entity.jpa.SpringDataUserJpa;
import org.springframework.context.annotation.Profile;
import org.springframework.stereotype.Repository;
#Repository
#Profile("jpa")
public interface SpringDataUserJpaRepository extends SpringDataUserRepository<SpringDataUserJpa> {
}
Mongo DAO:
package net.breezeware.runway.idm.dao.mongo;
import net.breezeware.runway.idm.dao.SpringDataUserRepository;
import net.breezeware.runway.idm.entity.mongo.SpringDataUserMongo;
import org.springframework.context.annotation.Profile;
import org.springframework.stereotype.Repository;
#Repository
#Profile("mongo")
public interface SpringDataUserMongoRepository extends SpringDataUserRepository<SpringDataUserMongo> {
}
As you have noticed, I am trying to get help from spring-data's automatic DAO implementation generation feature as defined below.

I have included the Service class that uses the DAO to access the stores:
package net.breezeware.runway.idm.service.impl;
import java.util.List;
import net.breezeware.runway.idm.dao.SpringDataUserRepository;
import net.breezeware.runway.idm.entity.SpringDataUser;
import net.breezeware.runway.idm.service.api.IdmService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
#Service
public class IdmServiceImpl implements IdmService {
#Autowired
SpringDataUserRepository<SpringDataUser> springDataUserRepository;
#Transactional
public SpringDataUser saveSpringDataUser(SpringDataUser user) {
// return springDataUserRepository.save(user);
return null;
}
#Transactional
public List<SpringDataUser> findSpringDataUsersByLastName(String lastName) {
return springDataUserRepository.findByLastName(lastName);
}
#Transactional
public List<SpringDataUser> findAllSpringDataUsers() {
return (List<SpringDataUser>) springDataUserRepository.findAll();
}
}
I have the following Application file that serves as the entry point to the App:
package net.breezeware.runway.idm;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
#Configuration
#ImportResource(value = {"classpath:applicationContext.xml"})
#EnableAutoConfiguration
#ComponentScan
public class IdmApplication {
public static void main(String[] args) throws Exception {
Logger logger = LoggerFactory.getLogger(IdmApplication.class);
SpringApplication.run(IdmApplication.class, args);
logger.info("Inside main method of IdmApplication");
}
}
Here is he code I have to test the service functionality.
package net.breezeware.runway.idm;
import net.breezeware.runway.idm.entity.SpringDataUser;
import net.breezeware.runway.idm.entity.jpa.SpringDataUserJpa;

//#ContextConfiguration({"classpath:**/applicationContext.xml"})
// #EnableAutoConfiguration

public class IdmServicesJpaTest extends AbstractTestNGSpringContextTests {
Logger logger = LoggerFactory.getLogger(IdmServicesJpaTest.class);
#Autowired
private IdmService idmService;
#Test
public void createSpringDataUserTest() {
logger.info("========== createSpringDataUserTest() ==========");
SpringDataUser user = new SpringDataUserJpa();
try {
user.setId(1);
user.setEmail("mark#gmail.com");
user.setFirstName("mark");
user.setLastName("adams");
user.setMiddleInitial("");
logger.info("SpringDataUser to be saved = " + user);
SpringDataUser savedUser = idmService.saveSpringDataUser(user);
logger.info("Saved User = " + savedUser);
} catch (Exception e) {
logger.info("Exception Occured = " + e);
}
}
}
I would like to use the 'Profile' feature in Spring to choose the DAO implementation in run-time. I expect the code to work, but unfortunately I have trouble getting the DAO interfaces to be autowired into Service classes. It seems like the DAO/Repository implementations for the SpringDataUserRepository is not not created by Spring-Data. Here is the error in my log file when I try to run the test.

I just could not get the DAOs instantiated/autowired into the Service class. I have tried different settings like marking the base entity Object 'SpringDataUser' with #MarkedSuperclass and such, but nothing seems to work.
Please let me know if I am missing something. I have spent a considerable amount of time on StackOverflow to find an answer but could not find one that solves my problem.
Thanks in advances.
I have a form where i input details, but when i click on save it does not get saved in the database... though the table does get created.

You need a running transaction. Spring transaction management is the way to go if using HibernateTemplate. Read the documentation. It's too long to include in an answer, but here is in short:
you need to define a transaction manager as a spring bean
you need <tx:annotation-driven />
you need to annotate your transactional methods with #Transactional
I don't know the Spring-Hibernate framework, but often when data is not written it menas it is not flushed to the databackend. What gives you
System.err.println(hibernateTemplate.getFlushMode());
I have 2 entities User and Status. I can load users list and can see its sql(log) in console
(select this_.id as id0_0_,
this_.cl_point_id as cl2_0_0_,
this_.date_ll as date3_0_0_,
this_.date_reg as date4_0_0_,
this_.name as name0_0_,
this_.passw_salt as passw6_0_0_,
this_.status_id as status7_0_0_,
this_.passw as passw0_0_, this_.login
as login0_0_ from users this_)
.
But when I load Status the list is empty and there is no sql(log) in console. I can't find where is the problem?

The Status entity looks fine (it has an #Entity annotation, it has a default no-arg constructor, it has an #Id), I can't spot anything obvious.
So I would:
double check the startup logs to check for any complaint.
use the Hibernate Console (if you are using Eclipse) or any equivalent to load the Status using raw HQL or Criteria.
write a unit test anyway.
Oh, by the way, this is unrelated but you shouldn't have such things in your User entity:
#Column(name="status_id")
private Long statusId;
These Long look like foreign keys. When using an ORM, you should have objects and associations between objects, not ids. Something like this:
#ManyToOne
private Status status;
Same remark for clPointId.
You are IMHO thinking "too relational" and "not enough object". I might be wrong but having foreign key attributes in an entity is a strong hint.
I have changed #Column(name="status_id") private Long statusId; to #ManyToOne private Status status; Now I receiving the ERROR: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: #OneToOne or #ManyToOne on tj.eskhata.pos.domain.User.status references an unknown entity: tj.eskhata.pos.domain.Status
This message clearly shows that something goes wrong with Status that isn't recognized as an Entity (and thus can't be referenced in an association, preventing the session factory from being instantiated). This is usually due to a configuration or mapping problem. So:
Do you declare entities somewhere (in hibernate.cfg.xml or in persistence.xml)? If yes, did you declare Status? If you are using classpath scanning, is Status scanned?
Double-check the mapping, check that the column names really exist (it's unclear if you are using an existing physical model).
Activate logging (Spring Logging, Hibernate Logging), this is helpful during development and will help to find the problem.
