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.classpublic class UsuarioDao {
public void salvar(Usuario usuario, Conexao conexao){
String sql = "INSERT INTO USUARIOS VALUES(" + usuario.getLogin() + ")";
System.out.println("DAO: Executando SQL=[" + sql + "]");
conexao.executar(sql);
}
}
class Usuario {
public Usuario(String nome) {
}
public String getLogin() {
return " fabioebner";
}
}
class Conexao {
public void executar(String sql) {
System.out.println("executado");
}
boolean isAberta() {
return false;
}
void abrir() {
System.out.println("abrir");
}
void fechar() {
System.out.println("fechar");
}
}
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;
}
}
}
