Results query inner join (jdbc) in table (view) Spring MVC - spring

Question

Could someone help me as I show the result of an inner join query in a view in Spring.
How do I return all fields from all inner join tables and show in view?
Ex from Model Class:
#NotEmpty(message="Destino não pode estar vazio")
private Integer idDestinoAgendamento;
private Integer idMotoristaAgendamento;
private Integer idAutomovelAgendamento;
private Integer idRotaAgendamento;
#NotEmpty(message="Data não pode estar vazia")
private String dataSolicitacaoPacApp;
#NotEmpty(message="Hora não pode estar vazia")
private String horaSolicitacaoPacApp;
#NotEmpty(message="Status não pode estar vazio")
private String statusAgendamento;
private Destino destino;
private Motorista motorista;
private Automovel automovel;
Ex do DAO:
public List buscarTodosAgendamentos()
{
String sql = "SELECT * FROM bAgendamento AS agendamento INNER JOIN bsDestino AS destino"
+ " ON agendamento.idDestinoAgendamento = destino.idDestino INNER JOIN"
+ " bsMotorista AS motorista ON agendamento.idMotoristaAgendamento = motorista.idMotorista "
+ " INNER JOIN bsAutomovel AS automovel ON agendamento.idAutomovelAgendamento = "
+ " automovel.idAutomovel INNER JOIN bsRota AS rota ON agendamento.idRotaAgendamento ="
+ " rota.idRota ORDER BY agendamento.dataSolicitacaoPacAPP ASC "
List list =
namedParameterJdbcTemplate.query(sql,getSqlParameterByModel(null), new AgendamentoMapper());
return list;
}
View (return fields object Destino, Automovel...):
c:forEach items="${listAgendamento}" var="agendamento"
${agendamento.idAgendamento}
${agendamento.cpfPacienteSolicitacaoPacApp}
${agendamento.idDestinoAgendamento}
${agendamento.idMotoristaAgendamento}
${agendamento.idAutomovelAgendamento}
${agendamento.idRotaAgendamento}
${agendamento.dataSolicitacaoPacApp}
${agendamento.horaSolicitacaoPacApp}
${agendamento.statusAgendamento}
