I am trying to write a SOAP service using Spring, however I receive a Dependency Injection issue. I'm having problems using @Autowired
through the Service like this:
public interface UserDao {
User getUser(String username);
}
Implementation for Dao as below:
@Controller("userDao")
public class UserDaoImpl implements UserDao {
private static Log log = LogFactory.getLog(UserDaoImpl.class);
@Autowired
@Qualifier("sessionFactory")
private LocalSessionFactoryBean sessionFactory;
@Override
public User getUser(String username) {
Session session = sessionFactory.getObject().openSession();
// Criteria query = session.createCriteria(Student.class);
Query query = session
.createQuery("from User where username = :username");
query.setParameter("username", username);
try {
System.out.println("\n Load Student by ID query is running...");
/*
* query.add(Restrictions.like("id", "%" + id + "%",
* MatchMode.ANYWHERE)); return (Student) query.list();
*/
return (User) query.uniqueResult();
} catch (Exception e) {
// TODO: handle exception
log.info(e.toString());
} finally {
session.close();
}
return null;
}
}
and
public interface UserBo {
User loadUser(String username);
}
and
public class UserBoImpl implements UserBo {
@Autowired
private UserDao userDao;
@Override
public User loadUser(String username) {
// TODO Auto-generated method stub
return userDao.getUser(username);
}
}
@WebService
@Component
public class UserService {
@Autowired
private UserBo userBo;
@WebMethod(operationName = "say")
public String sayHello(String name) {
return ("Hello Java to " + name);
}
@WebMethod(operationName = "getUser")
public User getUser(String username) {
return userBo.loadUser(username);
}
}
The below is xml mapping file

Look at the exception:
No qualifying bean of type [edu.java.spring.ws.dao.UserDao] found for dependency
This means that there's no bean available to fulfill that dependency. Yes, you have an implementation of the interface, but you haven't created a bean for that implementation. You have two options:
UserDaoImpl
with @Component
or @Repository
, and let the component scan do the work for you, exactly as you have done with UserService
.UserBoImpl
.Remember that if you create the bean explicitly you need to put the definition before the component scan. In this case the order is important.
