Hi there,
For some time now I have been trying to put together a simple project to get
me off the ground with a Wicket/Spring/Hibernate setup. I've had lots of ups
and downs, and found this guide really useful:
http://wicketinaction.com/2009/06/wicketspringhibernate-configuration/
However, I still seem to be having some problems and I've no idea where to
look now.
Here's the error I get in my log:
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'userServiceImpl' defined in file
[C:\tomcat6\webapps\ZenTemplate-0\WEB-INF\classes\uk\co\company\product\business\spring\UserServiceImpl.class]:
Instantiation of bean failed; nested exception is
org.springframework.beans.BeanInstantiationException: Could not instantiate
bean class [uk.co.company.product.business.spring.UserServiceImpl]:
Constructor threw exception; nested exception is org.apache.wicket.Wicket

public class WicketApplication extends AuthenticatedWebApplication{

}
}
my CustomAuthenticatedWebSession:
public class CustomAuthenticatedWebSession extends AuthenticatedWebSession{
private static final long serialVersionUID = 4713195500103052768L;
@SpringBean
private UserService userService;
public void setUserService(final UserService userService){
this.userService = userService;
}
transient private String currentUser = null;
public CustomAuthenticatedWebSession(final Request request){
super(request);
InjectorHolder.getInjector().inject(this);//<-- VERY IMPORTANT to
get Spring DI to work.
}

password){
currentUser = username;
return userService.authenticate(username, password);
}
@Override
public Roles getRoles(){
return userService.getRoles(currentUser, isSignedIn());
}
}
my UserServiceImpl.java:
@Service
public class UserServiceImpl extends _AbstractService implements
UserService{
final private TestUserService testUserService = new TestUserService();
@SpringBean
private Temp1DAO temp1DAO;
/* (non-Javadoc)
* @see
uk.co.company.product.business.spring.UserService#setTemp1DAO(uk.co.company.product.persistance.hibernate.Temp1DAO)
*/
@Override
@Required
final public void setTemp1DAO(final Temp1DAO temp1dao){
temp1DAO = temp1dao;
}
public UserServiceImpl(){
super();
InjectorHolder.getInjector().inject(this);//<-- VERY IMPORTANT to
get Spring DI to work.
}
/* (non-Javadoc)
* @see
uk.co.company.product.business.spring.UserService#authenticate(java.lang.String,
java.lang.String)
*/
@Override
@Transactional
final public boolean authenticate(final String userName, final String
password){
final Temp1 temp1 = new Temp1();
temp1.setValue(userName);
temp1DAO.save(temp1);
return testUserService.authenticate(userName, password);
}
/* (non-Javadoc)

}
and finally Temp1DAOImpl.java:
@Repository
public class Temp1DAOImpl extends AbstractTemp1DAO implements Temp1DAO{
private static final Log log = LogFactory.getLog(Temp1DAOImpl.class);
public Temp1DAOImpl(){
super();
log.debug("Temp1DAO created.");
}
}
I did have this working to the point where it would start up without errors,
although it would die when trying to call userServiceImpl.authenticate() due
to a NPE for temp1DAO. (It seemed odd before that it would do DI for
Services but not for DAOs...)
I'm sure I'm missing something blindingly obvious, but I'd really appriciate
a second opinion.
Thanks in advance for all help and assistance!!
Cheers,
Adam
