我有以下的方法休眠DAOImpl,傳遞一個變量作爲參數..找不到方法[的someMethod]與[1]參數
public List<Oportunidad> verParticipantes(String numeroOportunidad) throws DAOException {
List<Oportunidad> lista = getHibernateTemplate().find("SELECT c.cliente FROM Oportunidad o ,OportunidadParticipante op,"
+ "Cliente c WHERE op.oportunidad=o.id and c.idCliente=op.cliente and o.numeroOportunidad=?",numeroOportunidad);
return lista;
}
和ServiceImpl
public List<Oportunidad> verParticipantes(String numeroOportunidad)throws DAOException {
return getOportunidadDao().verParticipantes(numeroOportunidad);
}
此在兩者中都使用接口。 這些編譯和運行與junit做測試。 goog,很好
的問題是,當我想通過參數從selectOneListboxt實現的JSF primefaces
代碼ManagedBean:
public String getVerParticipantes(String numeroOportunidad) throws DAOException{
Oportunidad o = new Oportunidad();
o.setNumeroOportunidad(numeroOportunidad);
verParticipantes.addAll(getOportunidadService().verParticipantes(numeroOportunidad));
return "envioCotizacion.xhtml";
}
JSF代碼(XHTML):
<p:selectOneListbox id="listaCliente" value="#{clienteMB.cliente}" style="width:26%; height:90%; position:absolute; top:10%; left:12%;">
<f:selectItems value='#{oportunidadMB.verParticipantes("prueba")}'/>
<!-- <f:param name="numeroOportunidad" value="prueba" />-->
<p:ajax id="numeroOportunidad" listener='#{oportunidadMB.verParticipantes("prueba")}'></p:ajax>
</p:selectOneListbox>
