Hi there,
I was wondering if anyone could help me with spring annotations, I seem to
have having some problems.
I'm trying to inject my UserService into a CustomAuthenticatedWebSession I
wrote to do validation for my pages.
I get a NPE when I hit any page because my bean does not seem to have been
injected.
Here's my AuthenticatedWebSession Class:
public class CustomAuthenticatedWebSession extends AuthenticatedWebSession{
private static final long serialVersionUID = 4713195500103052768L;
@SpringBean(name="userService")
transient private UserService userService;
public void setUserService(final UserService userService){
this.userService = userService;
}
transient private String currentUser = null;
public CustomAuthenticatedWebSession(final Request request){
super(request);
}
@Override
public boolean authenticate(final String username, final String
password){
currentUser = username;
return userService.authenticate(username, password);
}
@Override
public Roles getRoles(){
return userService.getRoles(currentUser, isSignedIn());
}
}
my applicationContext.xml file:

Also here is my simple service:
@Service("userService")
public class UserService{
final private TestUserService testUserService = new TestUserService();
public UserService(){
super();
}
@Transactional
final public boolean authenticate(final String userName, final String
password){
return testUserService.authenticate(userName, password);
}
@Transactional
final public Roles getRoles(final String userName, final boolean
signedIn){
return testUserService.getRoles(userName, signedIn);
}
}
If anyone has any ideas please let me know!
Cheers,
Adam
