I have an XML configuration as follows:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:component-scan base-package="bamAddressbook.service"/>
<context:component-scan base-package="bamAddressbook.repository.addressbook"/>
And then in those packages I have the following classes:
@Service
public class BamService {
@Autowired
BamAddressbookDAO addressbookDao;
@Transactional
public void businessLogic() {
Addressbook addressbook = new Addressbook();
addressbookDao.makePeristent(addressbook);
}
}
@Repository
public class AddressbookDAOHibernate extends HibernateGenericDAO<Addressbook> implements BamAddressbookDAO {
@Override
public Addressbook getFromUser(User user) {
throw new UnsupportedOperationException("Not supported yet.");
}
}
public interface BamAddressbookDAO extends InterfaceGenericDAO<Addressbook>{
public Addressbook getFromUser(User user);
}
.
public interface InterfaceGenericDAO<T> {
public T get(Long databaseID);
public List<T> getAll();
public void makePeristent(T entity);
public void makeTransient(T entity);
}
I am getting no exceptions in the logs when I start the spring application context, yet when I try the following servlet it cannot find any beans, and I get a NoSuchBeanDefinitionException. Any bean I try to access which has been configured in XML seems to work fine:
public class BamServlet extends HttpServlet {
@Override
protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(
req.getSession().getServletContext());
BamService bean = (BamService) context.getBean("bamService");
}
}
I am tearing my hair out with this problem!
Change @Service to @Service("bamService") or change `
BamService bean = (BamService) context.getBean("bamService");
`to
BamService bean = context.getBean(BamService.class);
and save your hair :)
