Bom dia a todos.
Sr's estou tendo um problema na minha aplicação criei um crud simples utilizando Spring 3.0, hibernate 3.5 ,MySql e quando tento gravar uma tarefa
ele roda, mas me devolve um NullPointEx.
Eu utilizei o debug,ele mostra que a SessionFactory dele esta indo null,e no meu DAO, eu não consigo utilizar a anotação"@Autowired" pq quando eu salvo o TomCat me mostra o seguinte Erro:
606 [ContainerBackgroundProcessor[StandardEngine[Catalina]]] ERROR org.springframework.web.servlet.DispatcherServlet - Context initialization failed
