Pessoal estou reescrevendo um codigo que estava em HSQL de uma query para Criteria, mas não estou conseguindo alguem pode me ajudar, pois na Documentação do Hibernate não tem tantos exemplos:
codigo em HSQL:StringBuilder sql = new StringBuilder("from ");
sql.append("Centrocusto cc ");
sql.append("where ");
sql.append("cc.ativo = true and ");
sql.append("cc.clienteportal.grupoclientesForIdclipart.id.clienteportalByIdcliprinc.id = :idcli ");
sql.append(" and not exists (from ");
sql.append("Centrocusto cc ");
sql.append("where ");
sql.append("cc.ativo = true and ");
sql.append("cc.clienteportal.grupoclientesForIdcliprinc.id.unilateral = true and ");
sql.append("cc.clienteportal.grupoclientesForIdcliprinc.id.clienteportalByIdclipart.id = :idcli )");
Query query = this.dao.getSession().createQuery(sql.toString());
query.setInteger("idcli",usuario.getClienteportal().getId());
DetachedCriteria subQuery = DetachedCriteria.forClass(Centrocusto.class,"cc2");
subQuery.createAlias("cc2.clienteportal", "cl2");
subQuery.createAlias("cl2.grupoclientesForIdcliprinc", "gruCli2");
subQuery.createAlias("gruCli2.clienteportalByIdclipart", "clPart2");
subQuery.add(Restrictions.eq("cc2.ativo",true));
subQuery.add(Restrictions.eq("gruCli2.unilateral",true));
subQuery.add(Restrictions.eq("clPart2.id",usuario.getClienteportal().getId()));
Criteria crit = this.dao.getSession().createCriteria(Centrocusto.class);
crit.createAlias("clienteportal", "cl");
crit.createAlias("cl.grupoclientesForIdclipart", "grCli");
crit.createAlias("grCli.clienteportalByIdcliprinc", "clPri");
crit.add(Restrictions.eq("ativo",true));
crit.add(Restrictions.eq("clPri.id",usuario.getClienteportal().getId()));
crit.add(Subqueries.notExists(subQuery));
List lista2 = crit.setCacheable(true).list();
