i was going throw this issue but i found a solution but i have some error to do it so i ask this new question, here is my code :
#Service
public class GestionAOService {
#Autowired
private GenericDao<AoFollow, Integer> ao_follow_dao;
#Transactional
public void follow_ao(Integer idcontact , Integer idao) {
ao_follow_dao.create(new AoFollow(new AppelOffre(idao) , new Contact(idcontact)));
ao_follow_dao.read(1);
}
.....
My config
#Configuration
#ComponentScan("service")
public class AnnotationContextConfiguration {
#Bean(autowire = Autowire.BY_NAME)
public GenericDaoJpaImpl<AoFollow, Integer> ao_follow_dao() {
System.out.println("Autowire.BY_NAME");
return new GenericDaoJpaImpl<AoFollow, Integer>(AoFollow.class);
}
}
the problem is that nothing happened when i do ao_follow_dao.read(..); , the create (insert) is okey but i got NullPointerException int this level return this.entityManager.find(entityClass, id);
#Override
public T read(PK id) {
return this.entityManager.find(entityClass, id);
}
I think the bean is not correctly initialized with #Configuration cause it's the first time when I try it.
My imp class
#Repository
public class GenericDaoJpaImpl<T, PK extends Serializable>
implements GenericDao<T, PK> {
protected Class<T> entityClass;
#PersistenceContext
protected EntityManager entityManager;
public GenericDaoJpaImpl() {
}
public GenericDaoJpaImpl(Class<T> entityClass) {
this.entityClass = entityClass;
}
#Override
public T create(T t) {
this.entityManager.persist(t);
return t;
}
#Override
public T read(PK id) {
return this.entityManager.find(entityClass, id);
}
#Override
public T update(T t) {
return this.entityManager.merge(t);
}
#Override
public void delete(T t) {
t = this.entityManager.merge(t);
this.entityManager.remove(t);
}
#Override
public void delete(Set<T> ts) {
for( T t : ts){
t = this.entityManager.merge(t);
this.entityManager.remove(t);
}
}
}
my interface :
public interface GenericDao<T, PK extends Serializable> {
T create(T t);
T read(PK id);
T update(T t);
void delete(T t);
void delete(Set<T> ts);
}
I have also a xml configuration file

Add #Transactional annotation to your Service:
#Service
#Transactional
public class GestionAOService {
...
}
And make sure your AnnotationContextConfiguration Class is on a package that is scanned by the spring framework like service and dao.
Assuming that your class is on the package config, add this line to your spring configuration :
<context:component-scan base-package="config"/>

}
controller is fine.. i think..
service
#Service
public class BoardService {

public List<BoardDto> listboard(BoardDto dto) {
System.out.println("boardservice");
List<BoardDto> result = bDao.listboard(dto);
return result ;
}
}
this position is error why?? T.T
i think this method is error position but i don't know understand. why???
dao

#Autowired

why error is 'boom'? i didn't understand.... T.T

I think your problem is related with the lack of a #Component annotation in your BoardDao class.
The component should have a #Component annotation to instantiate the singleton to be injected in your Service Layer.
#Component
public class BoardDao extends SqlSessionDaoSupport{
#Autowired
SqlSessionTemplate session;
public List<BoardDto> listboard(BoardDto dto) {
System.out.println("dao.");
List<BoardDto> result = session.selectList("boarddate.listboard", dto);
return result;
}
}
If the problem persist, you may try with the #Repository annotation. Sadly I haven't used the class SqlSessionDaoSupport, so I don't know exactly the best annotation for that.
In my case it was with a Map, I wanted to increase its value, but this initial one will not exist, therefore it is null.
map.put(0, map.get(0) 1);
It was fixed by adding a validation, like so:
map.put(0, map.get(0) != null ? map.get(0) + 1 : 1);
I have to autowire a service into my ItemProcessor to retrieve an object from the database and make some treatment but it's not working and I always gets java.lang.NullPointerException when trying to use it in my ItemProcessor.
Here is the context-model:

I have another configuration applicationContext in web-inf But when I run the batch I access this configuration which are in resources class path.
Below is my code. I am using remoting to get reference to the service. once i get the service reference and try to get event.dao call i get a NPE in EventServiceImpl class. When I use xml based config it works but i want it to be annotation based.
EventDao.class
public interface EventDao {
void saveEvent(Event employee);
List<Event> findAllEvents();
void deleteEmployeeBySsn(String ssn);
Event findBySsn(String ssn);
void updateEvent(Event employee);
}
EventImplDao.class
#Repository
public class EventDaoImpl extends AbstractDao implements EventDao{
public void saveEvent(Event employee) {
persist(employee);
}
#SuppressWarnings("unchecked")
public List<Event> findAllEvents() {
Criteria criteria = getSession().createCriteria(Event.class);
return (List<Event>) criteria.list();
}
EventServiceImpl
#Service
#Transactional
public class EventServiceImpl implements EventService{
private EventDao eventDao;
public void setEventDao(EventDao eventDao) {
this.eventDao = eventDao;
}
public void saveEvent(Event employee) {
eventDao.saveEvent(employee);
}
public List<Event> findAllEvents() {
return eventDao.findAllEvents();
}
EventService
#ServiceInterface
public interface EventService {
void saveEvent(Event employee);
List<Event> findAllEvents();
void deleteEmployeeBySsn(String ssn);
Event findBySsn(String ssn);
void updateEvent(Event employee);

Here is the Service Method-
public class registrationService {
private HibernateTemplate hibernateTemplate;
public registrationService()
{
}
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
public boolean regUser(com.imall.pojo.regUser rgUser)
{
System.out.println(rgUser.getfName());
try
{
System.out.println("in try--"+rgUser.getEmailId());
hibernateTemplate.save(rgUser);
return true;
}
catch(Exception e)
{
System.out.println("Catch");
e.printStackTrace();
return false;
}
}
Any help will be appreciated.
Here are the other code -
LoginController Method-
#Autowired
private registrationService regService;
#RequestMapping(value="/register.php",method = RequestMethod.POST)
public ModelAndView registerUser(#ModelAttribute("regDetails") regUser userReg)
{
System.out.println(userReg.getfName());
if(regService.regUser(userReg))
{
System.out.println("IF");
return new ModelAndView("success");
}
else
{
System.out.println("else");
return new ModelAndView("success");
}
}
The line 29 in RegistrationService is- hibernateTemplate.save(rgUser);
And this line System.out.println(rgUser.getfName()); is printing the name.
I have a dynamic web project which I did not use Maven (so, I do not have pom.xml). My controller works for HelloWorldController which I created for testing purposes. I'm getting following error which I thought as related with service or JpaDao classes. I will also add those files. If there is anything else you need, I can also add and update my post. Thanks in advance.
