public class AppServlet extends HttpServlet   {

@Autowired
ApplicationContext applicationContext;

public void init(ServletConfig arg0) throws ServletException {
     WebApplicationContextUtils.getWebApplicationContext(arg0.getServletContext())
        .getAutowireCapableBeanFactory().autowireBean(this);
}

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

        PrintWriter out = resp.getWriter();

        out.println("execução iniciada em: " + new Date());

        GerenciadorTasks gt = (GerenciadorTasks) this.applicationContext.getBean(SpringNameBeans.GERENCIADOR_TASKS);
