Galera, estou começando a utilizar o mentawai e acredito que descobri um problema.
Peguei a aplicação de referência, que carrega o filtro de transações no método
Code:
@Override
public void loadFilters() {
}
no AppManager.java do projeto. Carregando dessa forma, o filtro está sendo chamado para todas as actions, mas não está dando rollback. Montei um projeto de teste provocando uma exceção na ação para mostrar, que segue abaixo.
Olhei na documentação da versão anterior do menta http://old.mentaframework.org/transfilter.jsp?loc=pt e vi que existia uma outra forma de instanciar o filtro. Da forma antiga funcionou corretamente o rollback da transação. Mas, no mesmo exemplo, da forma nova, no loadFilters() não funciona.
Coloco abaixo o código do exemplo e também o stacktrace com debug ativado.
Sobre o debug, nãoi sei se é um erro, mas tive que ativar o debug duas vezes, uma para olhar as mensagens gerais do framework e outra para olhar as mensagens de debug do TransactionFilter, postei esse problema em outro tópico: http://forum.mentaframework.org/posts/list/0/9185.page
Code:
package org.events;
import org.events.action.UsuarioAction;
import org.mentawai.core.ApplicationManager;
import org.mentawai.core.Context;
import org.mentawai.core.Props;
import org.mentawai.db.ConnectionHandler;
import org.mentawai.db.DBCPConnectionHandler;
import org.mentawai.filter.ConnectionFilter;
import org.mentawai.filter.ExceptionFilter;
import org.mentawai.filter.MentaContainerFilter;
import org.mentawai.filter.TransactionFilter;
import org.mentawai.log.Debug;
import org.mentawai.transaction.JdbcTransaction;
public class AppManager extends ApplicationManager {
private Props props;
@Override
public void init(Context application) {
this.props = getProps();
setDebugMode(true);
Debug.enable(true);
}
@Override
public ConnectionHandler createConnectionHandler() {
String driver = props.getString("jdbc.driver");
String url = props.getString("jdbc.url");
String user = props.getString("jdbc.user");
String pass = props.getString("jdbc.pass");
return new DBCPConnectionHandler(driver, url, user, pass);
}
@Override
public void loadFilters() {
filter(new MentaContainerFilter());
// o filtro de transação não funcionou carregando por aqui
filter(new TransactionFilter());
filter(new ExceptionFilter());
on(EXCEPTION, fwd("/error.jsp"));
filter(new ConnectionFilter(getConnectionHandler()));
}
@Override
public void setupIoC() {
ioc("transaction", JdbcTransaction.class);
}
@Override
public void loadActions() {
// filtro de transação FUNCIONOU carregando por aqui
//addGlobalFilter(new TransactionFilter());
action("/Usuario", UsuarioAction.class, "listar")
.on(SUCCESS, fwd("/WEB-INF/jsp/usuario/listar.jsp"))
.on(ERROR, fwd("/WEB-INF/jsp/usuario/listar.jsp"));
}
}
Code:
package org.events.action;
import java.util.ArrayList;
import org.events.model.Usuario;
import org.mentawai.core.BaseAction;
import org.mentawai.log.Debug;
public class UsuarioAction extends BaseAction {
public String listar () throws Exception {
if (Debug.isEnabled()) Debug.log("TESTE NA AÇÃO...", "Chamando método UsuarioAction.listar...");
ArrayList<Usuario> usuarios = new ArrayList<Usuario>();
String teste = null;
// Provocar exceção em tempo de execução para testar o filtro de transações. Conferir no log
teste.getBytes();
output.setValue("usuarios", usuarios);
return SUCCESS;
}
}
