Мы работаем над проектом Spring mvc и испытываем некоторые проблемы с производительностью наших вызовов ajax. Каждый звонок занимает минимум 500мс :(.
У кого-то была эта проблема раньше? Есть ли хороший способ профилировать эту проблему?
Мы используем:
- пружинный мвк
- пружина безопасности
- Спящий режим 3.6.1
- кот 7
- JQuery 1.4.4
После использования профилировщика Spring Insight мы обнаружили, что это проблема:
try {
HibernateTemplate ht = new HibernateTemplate(sf);
List<Route> r = ht.findByNamedParam("select r from Route r inner join r.carPoolers as carPooler where (( r.owner.id = :userid ) or ( carPooler.user.id = :userid )) AND r.id =:routeID", new String[]{"userid", "routeID"} , new Object[]{ u.getId() , id});
if (r.size() == 1) {
return r.get(0);
} else {
return null;
}
} catch (DataAccessException ex) {
LogFactory.getLog(RouteRepository.class).fatal(ex);
return null;
}
Этот запрос занимает минимум 460 мс ...
