Boa Noite,
Estou desenvolvendo um projeto utilizando o Vraptor3 utilizando o modelo MVC.
O codigo abaixo funciona perfeitamente:
Contexto:
@Resource
public class MainController {
private final Result result;
public MainController(Result result) {
this.result = result;
}
...
}
No entanto, quando adiciono o Objeto DAO obtenho um erro estranho:
@Resource
public class MainController {
private final ContratoEletronicoDAO dao;
private final Result result;
public MainController(ContratoEletronicoDAO dao, Result result) {
this.dao=dao;
this.result = result;
}
...
}
ERROR: HTTP Status 500 -
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mainController' defined in file [C:\Tomcat 6.0\webapps\smsw\WEB-INF\classes\leonardo\lsd\ic\unicamp\smsw\controller\MainController.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [leonardo.lsd.ic.unicamp.smsw.dao.ContratoEletronicoDAO]: : No matching bean of type [leonardo.lsd.ic.unicamp.smsw.dao.ContratoEletronicoDAO] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Preciso de alguma configuração adicional para utilizar o Objeto DAO no construtor do CONTROLLER?
Essa é a minha Classe DAO
public class ContratoEletronicoDAO
{
private Connection con;
public ContratoEletronicoDAO() throws SQLException{
this.con = ConnectionFactory.getConnection();
}
public void adiciona(ContratoEletronico ce) throws ClassNotFoundException, SQLException{
String sql = "INSERT INTO ContratoEletronico(data,arquivo,nome)VALUES (?,?,?)";
PreparedStatement stmt = con.prepareStatement(sql);
stmt.setString(1,ce.getData());
stmt.setString(2,ce.getArquivo());
stmt.setString(3,ce.getNome());
stmt.execute();
stmt.close();
con.close();
}
}
Obrigado pela ajuda.
