how to solve org.hibernate.TypeMismatchException?

I try to develop some server program using spring mvc and hibernate.
At my tables, some tables have two primray keys.
So, I want to use these keys.
Simply, I use double #Id annotations.
In the result, I got org.hibernate.TypeMismatchException.
Although I searched to solve error, I can't solve this problem...
help me please.
This is my model class.

import org.hibernate.annotations.NaturalId;
import org.hibernate.annotations.Parameter;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
#Entity
#Table(name="festival_info")

public class Interest implements Serializable{
#Id

private String interest;
#Id
#Column(name="festival_number", unique=true, nullable=false)

#GenericGenerator(name="gen", strategy="foreign", parameters=#Parameter(name="property", value="festival_info"))
private String festivalNumber;
public Interest(){
festivalNumber = "";
interest = "";
}
public Interest(String festivalNumber, String interest) {
this.festivalNumber = festivalNumber;
this.interest = interest;
}
public String getFestivalNumber() {
return festivalNumber;
}
public void setFestival_number(String festivalNumber) {
this.festivalNumber = festivalNumber;
}
public String getInterest() {
return interest;
}
public void setInterest(String interest) {
this.interest = interest;
}
#Override
public String toString(){
return festivalNumber + "," + interest;

Your problem is that you are using two #Id annotations in the same entity, you would rather use #EmbeddeId instead, so change this code:
#Id
#Column(name="interest")
private String interest;
#Id
#Column(name="festival_number", unique=true, nullable=false)
#GeneratedValue(generator="gen")
#GenericGenerator(name="gen", strategy="foreign", parameters=#Parameter(name="property", value="festival_info"))
private String festivalNumber;
To the following code:
public class Interest implements Serializable{
#EmbeddedId
private InterestId id;
//getters and setters and the rest of your code go here
}
And the InterestId class:
#Embeddable
public class Person implements Serializable {
private static final long serialVersionUID = 1L;
#Column(name="interest")
private String interest;
#Column(name="festival_number", unique=true, nullable=false)
#GeneratedValue(generator="gen")
#GenericGenerator(name="gen", strategy="foreign", parameters=#Parameter(name="property", value="festival_info"))
private String festivalNumber;
// and getters and setters here
}

You cannot use 2 #Id annotations for a composite primary key. You have to use #EmbeddedId Check this documentation and this Stackoverflow link.

org.springframework.transaction.CannotCreateTransactionException

I am getting the below error while trying to call a service class
org.springframework.transaction.CannotCreateTransactionException: Could not open JPA EntityManager for transaction; nested exception is java.lang.NullPointerException

//queueSvc.addQueue(queue);
logger.info(queueSvc.toString());
model.addAttribute("list", queueSvc.getAll());
return "home";
}
}

I can see some improvement needs to be done in the code.
1.Why you have annotated QueueService class with #Component,#Repository and #Service annotation all together,as per the code it contains,it should be annotated only with #Repository.
2.You have used #Transactional annotation at the class level,remove it from the individual method from this class.
3.In your servlet-context.xml file,you have below line
<context:component-scan base-package="com.plm.conn.model" />
make sure that you should have configured it correctly,it should scan the spring managed component,not your database entity,because according to your servlet-context.xml file,"com.plm.conn.model" is your entity package(see <beans:property name="packagesToScan" value="com.plm.conn.model" />)

I want to persist data without persistence.xml file. this is why I use Queue.java entity class which is in the com.plm.conn.model
I am new to the Spring I learned that we can persist the data without using persistence class. I modified servlet-context.xml as follows

I want to add object data and want to save in DB table, everything working fine but it gives me an error :

on line getSession().save(entity);
I have called this method in code :

private IPatronCategoryRepository patronCategoryRepository = new PatronCategoryRepository();
#Override
#Transactional(propagation = Propagation.REQUIRED)
public void Process(AddCategory command){
PatronCategory entity = new PatronCategory();
entity.setCategoryName(command.getCategoryName());
try
{
patronCategoryRepository.save(entity);
}catch (Exception e){
e.printStackTrace();
}
}
}
following is my xml file :

Here is a getSession() method :

return getSessionFactory().getCurrentSession();
}
Here is a sessionFactory declaration :

Any guesses why it's NULLPOINTEREXCEPTION ??

<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
and xml for transaction manager
<bean id="txManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven transaction-manager="txManager" />
in repository
#Autowired
protected SessionFactory sessionFactory;

Your config is a bit incomplete. You should delegate session management completely to Spring
Add in you spring xml file:
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
Then, in your PatronCategoryRepository class, extend HibernateDaoSupport and add this constructor:
public class PatronCategoryRepository extends HibernateDaoSupport implements IPatronCategoryRepository{
#Autowired
public PatronCategoryRepository(HibernateTemplate hibernateTemplate) {
super();
super.setHibernateTemplate(hibernateTemplate);
}
[...]
}
In AddCategoryProcessor, leave the definition of the repository like this:
#Autowired
private IPatronCategoryRepository patronCategoryRepository;
And finally your method:
#Override
#Transactional(propagation = Propagation.REQUIRED)
public void Process(AddCategory command){
PatronCategory entity = new PatronCategory();
entity.setCategoryName(command.getCategoryName());
try
{
getHibernateTemplate.save(entity);
}catch (Exception e){
e.printStackTrace();
}
}

In case you still need to access directy the SessionFactory, the only thing you have to do is inject it into PatronCategoryRepository:
#Repository
public class PatronCategoryRepository implements IPatronCategoryRepository{
#Autowired
protected SessionFactory sessionFactory;
public PatronCategoryRepository() {
}
public PatronCategory save(PatronCategory entity){
return getSession().save(entity);
}
private Session getSession() {
return sessionFactory.getCurrentSession();
}
}
And remember to remove the new clause from AddCategoryProcessor, leaving it like this:
#Autowired
private IPatronCategoryRepository patronCategoryRepository;

Spring security No Hibernate Session bound to thread

I searched the forum for this answer, but i could not find a solution.
I have configured my transaction manger bean
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
I have configured my session factory.
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="org.apache.derby.jdbc.ClientDriver"/>
<property name="url" value="jdbc:derby://localhost:1527/hibernate"/>
<property name="username" value="root"/>
<property name="password" value="root"/>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="annotatedClasses">
<list>
<value>org.krams.tutorial.domain.Person</value>
<value>org.krams.tutorial.domain.UserRole</value>
</list>
</property>
<property name="hibernateProperties">
<props>

<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
My daoImpl and Service class have #repository and #transactional tag
#Repository("personDao")
public class PersonDAOImpl implements PersonDAO {
#Autowired
private SessionFactory sessionFactory;
#Override
public void savePerson(Person person) {
sessionFactory.getCurrentSession().saveOrUpdate (person);
}
#Override
public Person findByName(String name){
String query = "select * from Person p where p.username='"+name+"'";
Person person = (Person) sessionFactory.getCurrentSession().createQuery(query);
return person;
}
}
#Service("userService")
#Transactional(propagation=Propagation.SUPPORTS, readOnly=true)
public class PersonServiceImpl implements PersonService{
#Autowired
private PersonDAO personDao;
#Override
#Transactional(propagation=Propagation.SUPPORTS, readOnly=false)
public void savePerson(Person person) {
personDao.savePerson(person);
}
#Override
#Transactional(propagation=Propagation.SUPPORTS, readOnly=true)
public Person findByName(String name){
return personDao.findByName(name);
}
}
I have one more service class for Spring Security database implementation
#Service("userDetailsService")
public class UserDetailsServiceImpl implements UserDetailsService {
#Autowired
private PersonService userService;
#Autowired
private Assembler assembler;
#Transactional(readOnly = true)
#Override
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException, DataAccessException {
try {
Person person = userService.findByName(username);
return (UserDetails) assembler.buildUserFromUserEntity(person);
} catch (NoResultException e) {
throw new UsernameNotFoundException(e.getLocalizedMessage());
}
}
}
stacktrace:

I am confused as where did i go wrong. Please guys help me out.

Looks like you have missed to enable the transaction support.
Add tx:annotation-driven to the configuration:
<beans
...
xmlns:tx="http://www.springframework.org/schema/tx"
...
xsi:schemaLocation="...
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
...
<tx:annotation-driven transaction-manager="transactionManager" />
