Ajuda Spring

GUJ Ranger Membro desde: 10/06/2005 14:07:00 Mensagens: 821 Offline

Pessoal estou comecando a mexer com spring para isso fui nesse site: http://blog.digows.com/integrando-adobe-flex-blazeds-springframework-hibernate-uma-soluo-opensource-para-sistemas-web-parte-2-final/

e peguei a apostila q se encontra aqui:
Primeiro de tudo, leia este artigo feito pelo Phillip Calçado (Shoes)
apostila-spring.pdf
Valeu Ebertom pela hospedagem! =)

legal ate ae beleza. estou tentando fazer o exercicio da pagina 29 Advice tipo Around..

perfeito.. eu fiz tudo certinho

segue as classes

UsuarioDao.class

Usuario.class

Conexao.class
VerificaConexaoDisponivelAdvice.class

public class VerificaConexaoDisponivelAdvice implements MethodInterceptor {

public Object invoke(MethodInvocation invocacao) throws Throwable {

Object[] argumentos = invocacao.getArguments();
// pega a conexão passada como parâmetro
        Conexao conexao = (Conexao) argumentos[1];
// se não existe conexão, retorne
        if (conexao == null) {
            System.out.println("Nenhuma conexão passada");
            return null;
        } else {
            // se a conexão existe mas não está aberta, abra-a
            if (!conexao.isAberta()) {
                System.out.println("Conexão fechada, abrindo...");
                conexao.abrir();
            }
            // execute o método
            try {
                System.out.println("Invocando...");
                invocacao.proceed();
            } catch (Throwable e) {
                // problemas na execução do método!
                e.printStackTrace();
            } finally {
                //Fechando conexão usada
                System.out.println("Fechando Conexão...");
                conexao.fechar();
            }
            // este método não tem retorno (void)
            return null;

}
    }
}

applicationContext.xml

e executarSpring.clss

td isso no netbeans.. fui la com o botao direito em library Add, adicionei a do Spring Framework 2.5 q vem com ele.. perfeito

o q pode ser??

valeu

Posta o codigo do seu bean usuarioDao e XML do spring, parece ter algo de errado com ele ou com sua configuracao no XML.

Dá uma olhada neste post http://www.guj.com.br/posts/list/89798.java.

Acho que irá ajudar.

Obrigado!

Oi, Scopel,

Você está tentando rodar o exemplo com uma cópia recente do Spring Framework, certo? Bom, essa apostila é de 2006, o Spring ainda estava na versão 1 (na verdade, a versão 2 foi lançada durante uma das turmas deste curso...) e hoje em dia temos o Spring 3! Eu nunca main tentei rodar os exemplos mas imagino que dificilmente seriam compatíveis...

Obrigado pelo up no tópico, entretanto. Desde 2006 que eu perdi esta apostila e finalment consegui uma cópia. Se conseguir algum tempo vou ver se a atualizo, parece que ela ajudou muita gente...

Grande homem...
pelo que ja visitei de topicos e foruns, observei que esta apostila ja passou na mao de muita gnt msm ... é otima para quem ta iniciando o estudo do spring aop, como eh meu caso., porem igual vc comentou os exemplos estao na versao 1 e nao estao sendo compativeis com as versoes recentes... é exatamente o que acredito que esta acontecendo comigo..
estou utilizando a versao Spring Framework 2.5, e tentando entender mais o conceito de @AspectJ
bom se conseguir me ajudar em relaçao ao erro acima agradeço, ou se tiver outros exemplos de implementaçoes de spring aop e quiser disponibilizar pra mim tentar entender tbm fico grato...
Vou torcer para vc ter tempo o quanto antes para atualizar a apostila....hehe
Grande abraço
td de bom
