Crudrepository - No qualifying bean of type found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency

I've looked through so many of these type of questions but no matter what I try it still comes up with this error.

The autowiring of "test" which is just a random class works fine but the interface extending the crudrepository won't autowire.

Any help would be greatly appreciated

You forgot to use the #Repository annotation in your repository interface (see docs).

What worked for me is adding the annotation #EnableJpaRepositories to the SpringBootApplication class and explicitly specifying the package where the repo is located. Your application class would look like:
#SpringBootApplication
#EnableJpaRepositories("the.package.to.your.repository")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class);
}
}

Maybe the problem in entity. Check the imports, they should be like org.springframework.data.relational.core.mapping.Column; and not javax.persistence.Column.

org.hibernate.MappingException: Unknown entity: library.model.Person

I've been struggling with this all day but haven't yet found a solution.
I have a simple entity mapping to a database table:
#Entity
#Table(name = "PERSON")
public class Person implements Serializable {
// Attributes.
#Id
#Column(name = "ID", unique = true, nullable = false)
#GeneratedValue(strategy=GenerationType.AUTO)
private Integer id;
#Column(name = "NAME", nullable = false, length=50)
private String name;
#Column(name = "ADDRESS", nullable = false, length=100)
private String address;
#Column(name = "TELEPHONE", nullable = false, length=10)
private String telephone;
#Column(name = "EMAIL", nullable = false, length=50)
private String email;
#OneToMany(cascade=CascadeType.ALL, fetch = FetchType.LAZY)
#JoinColumn(name="PERSON_ID")
private List<Book> books;
// Constructors.
public Person() {
this.id = 0;
this.name = ("");
this.address = ("");
this.telephone = ("");
this.email = ("");
this.books = null;
}
This entity is governed by a Spring controller with the following method:
#RequestMapping(value = "/register", method = RequestMethod.POST)
public String post(#ModelAttribute("person") Person person,
BindingResult bindingResult,
SessionStatus sessionStatus,
Model model /* ,
HttpSession session */) throws DAOException {
logger.info(PersonController.class.getName() + ".post() method called.");
personValidator.validate(person, bindingResult);
if (bindingResult.hasErrors()) {
return "register";
}
else {
// Write Person to database.
personService.insert(person);
// Set view.
sessionStatus.setComplete();
return "options";
}
}
The service class is:
#Service("personService")
#Transactional
public class PersonService {
#Autowired
PersonDAO personDAO;
public void insert(Person person) throws DAOException {
personDAO.insert(person);
}
And the DAO is as follows:
#Repository("PersonDAO")
public class PersonDAOImpl implements PersonDAO {
#Autowired
private SessionFactory sessionFactory;
static final Logger logger = Logger.getLogger(PersonDAOImpl.class.getName());
#Override
public void insert(Person person) throws DAOException {
logger.info(PersonDAOImpl.class.getName() + ".insert() method called.");
Session session = sessionFactory.openSession();
Transaction transaction = session.getTransaction();
try {
transaction.begin();
session.save(person);
transaction.commit();
}
catch(RuntimeException e) {
transaction.rollback();
throw new DAOException(e);
}
finally {
session.close();
}
}
And of course the part of my Spring servlet binding everything together:
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.DerbyDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.current_session_context_class ">thread</prop>
<!-- What to do with the database schema. -->
<prop key="hbm2ddl.auto">validate</prop>
<!-- validate: validate the schema, makes no changes to the database.
update: update the schema.
create: creates the schema, destroying previous data.
create-drop: drop the schema at the end of the session. -->
</props>
</property>
</bean>
So why am I getting the message:
org.hibernate.MappingException: Unknown entity: library.model.Person
If I try things like:
<property name="packagesToScan" value="library.model" />
<property name="annotatedClasses">
<list>
<value>library.model.Person</value>
</list>
</property>
At the moment I am getting:

Try replacing:
<property name="annotatedClasses">
<list>
<value>library.model.Person</value>
</list>
</property>
With:
<property name="packagesToScan">
<list>
<value>library.model</value>
</list>
</property>
In your sessionFactory properties.
If you get an error saying the property "packagesToScan" could not be found then you should add the spring-orm library to your project. If you're using maven then you can add:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>YOUR SPRING VERSION HERE</version>
</dependency>

Can't set up simple JPA

Im trying to configure a simple JPA project and im very stuck.
I have a working dataSource ( Oracle db ) with a table "SIMPLE" that contains an ID(NUMBER) and a WORD (VARCHAR2).
I keep getting an exception that sais there is something wrong with my named queries: SimpleObject.findById, SimpleObject.findAll, but they seem simple and i dont think I made mistakes there.
Here is the class that contains the queries. And I added all other classes and the full exception.
SimpleObject class that maps data from the table
package lt.tomas.proSpring3;
import javax.persistence.*;
#Entity
#Table(name = "simple")
#NamedQueries({
#NamedQuery(name="SimpleObject.findAll",query = "SELECT c FROM Simple c"),
#NamedQuery(name="SimpleObject.findById" , query = "SELECT c FROM Simple c where c.id = :id")
})
public class SimpleObject {
private Long id;
private String word;
#Id
#Column(name = "ID")
public long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
#Column(name = "WORD")
public String getWord(){
return word;
}
public void setWord(String word){
this.word = word;
}
public String toString(){
return "ID: " + id + " WORD: " + word ;
}
}
SimpleObjectImpl class that performs data operations on simpleObject
package lt.tomas.proSpring3;
import java.util.List;
import javax.persistence.*;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
#Service("jpaSimpleService")
#Repository
#Transactional
public class SimpleObjectImpl{
#PersistenceContext(unitName="emf")
private EntityManager em;
#Transactional(readOnly=true)
public List<SimpleObject> findAll(){
return em.createNamedQuery("SimpleObject.findAll", SimpleObject.class).getResultList();
}
#Transactional(readOnly=true)
public SimpleObject findById(Long id){
TypedQuery<SimpleObject> tq = em.createNamedQuery("SimpleObject.findById", SimpleObject.class);
tq.setParameter("ID", id);
return tq.getSingleResult();
}
public void save(SimpleObject s) {
em.persist(s);
}
public void update(SimpleObject s){
em.merge(s);
}
public void Delete(SimpleObject c) {
// TODO Auto-generated method stub
}
}
A class to test it all
package lt.tomas.proSpring3;
import java.util.List;
import org.springframework.context.support.GenericXmlApplicationContext;
public class JPATest {
public static void main(String[] args) {
GenericXmlApplicationContext ctx = new GenericXmlApplicationContext();
ctx.load("app-context.xml");
ctx.refresh();
SimpleObjectImpl si = ctx.getBean("jpaSimpleService", SimpleObjectImpl.class);
List<SimpleObject> objects = si.findAll();
for(SimpleObject obj : objects){
System.out.println(obj);
}
}
}

Can you tell me why is this exception comming up and waht am i doing wrong? Thank you in advance.

JPA NamedQuery doesn't allow you to do a select on a DB table, instead use the Entity class name instead (case sensitive).
So, change a SELECT c from Simple c to SELECT c to SimpleObject c
So here is the correct answers:
#NamedQuery(name="SimpleObject.findAll",query = "SELECT c FROM SimpleObject c"),
#NamedQuery(name="SimpleObject.findById" , query = "SELECT c FROM SimpleObject c where c.id = :id")
I hope this helps.

Add #JoinColumn(name="user_fk") and #JoinColumn(name="tvShow_fk") to your getUser_fk and getTvShow_fk.

I just had the same NullPointerException.
You will get this NPE if there is a typo in the column name of a #UniqueConstraint annotation

There was a bug report for this issue. The ticket has been fixed. If you update to hibernate 4.3 or later, there will be a better exception message.
PS: but in your case it's just because you didn't specify any column name on the join annotation (see the answer of #alex).

autowiring sessionbean with hibernate3 and spring3

Apologies as I'm relatively new to Spring. I have the following code...
org.assessme.com.dao.UserDAOImpl.java
#Repository
public class UserDAOImpl implements UserDAO{
#Autowired
private SessionFactory sessionFactory;
#Transactional
public User getById(Long id) {
return (User) sessionFactory.getCurrentSession().load(User.class, id);
}
}
This uses org.assessme.com.dao.UserDAO.java
public interface UserDAO {
public User getById(Long id);
}
When I try to run my program, I get...
ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDAOImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory org.assessme.com.bean.UserDAOImpl.sessionFactory; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Can anyone see what I'm doing incorrectly? I'm not quite sure how to autowire the sessionFactory.
My entity class is as follows...
org.assessme.com.entity.User.java
#Entity
#Table(name = "users")
public class User {
#Column(name = "firstName")
private String firstName;
#Column(name = "lastName")
private String lastName;
#Column(name = "email")
private String email;
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
#Column(name = "id")
private long 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 getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
}
Thanks,
I'm using this in springmvc by the way, should this be in servlet-context.xml?

Here is the relevant part of the error message:
NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory]
The problem is AnnotationSessionFactoryBean does not implement the org.hibernate.SessionFactory interface. To get one of those you need to call the buildSessionFactory method.
