Witam
Próbował ktoś kiedyś wstrzyknąć beana springowego do filtra. Poniżej moja próba rozwiązania.:
public class AuthFilter implements Filter{
@Autowired
public WorkersDAO workers;
@Override
public void destroy() {
// Do nothing
}
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
//Coś sie tutaj dzieje
}
@Override
public void init(FilterConfig filterConfig) throws ServletException {
ServletContext servletContext = filterConfig.getServletContext();
WebApplicationContext webApplicationContext = WebApplicationContextUtils.getWebApplicationContext(servletContext);
AutowireCapableBeanFactory autowireCapableBeanFactory = webApplicationContext.getAutowireCapableBeanFactory();
WorkersDAO obj = new WorkersDAOImpl();
autowireCapableBeanFactory.autowireBean(obj);
}
}
Wiem że filtr nie jest zarządzany ale takie coś podpowiedział mi google, ale dostaję błąd bo w klasie WorkersDAO wstrzykiwany jest inny bean:

WorkersDAO:
@Repository
public class WorkersDAOImpl extends GenericDAOImpl<Worker> implements WorkersDAO {
public WorkersDAOImpl() {
super(Worker.class);
}
@SuppressWarnings("unchecked")
@Override
public List<Worker> getAllWorkers(){
Query query = currentSession().createQuery("SELECT w FROM "+ clazz.getName()+" AS w LEFT JOIN FETCH w.role");
return query.list();
}
}
Oraz GenericDAO:
@Repository
public class GenericDAOImpl<E> implements GenericDAO<E> {
public Class<E> clazz;
public GenericDAOImpl() {}
public GenericDAOImpl(Class<E> clazz) {
this.clazz = clazz;
}
@Autowired
public SessionFactory factory;
protected Session currentSession() {
return factory.getCurrentSession();
}
@Override
public void save(E newInstance) {
currentSession().persist(newInstance);
}
@Override
public void saveOrUpdate(E newInstance) {
currentSession().saveOrUpdate(newInstance);
}
@SuppressWarnings("unchecked")
@Override
public E readById(Object id) {
E createQuery = (E) currentSession().createQuery(
"SELECT E FROM" + clazz.getName()+"AS E");
return createQuery;
}
@Override
public void update(E transientObject) {
currentSession().merge(transientObject);
}
@Override
public void delete(E persistentObject) {
currentSession().delete(persistentObject);
}
}
Jeżeli ktoś ma jakąś wskazówkę nie pogardzę. Dzieki;)
