от няколко дни се опитвам да разреша проблема, който се случва в моята програма, аз се опитах много начини за решаване, но нищо не работи. Ето следата на стека:

Тук е моят клас UsersDao:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.namedparam.MapSqlParameterSource;

import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;
@Transactional
@Component("usersDao")
public class UsersDao {
private NamedParameterJdbcTemplate jdbc;
@Autowired
private PasswordEncoder passwordEncoder;
@Autowired
private SessionFactory sessionFactory;
@Autowired
public void setDataSource(DataSource jdbc) {
this.jdbc = new NamedParameterJdbcTemplate(jdbc);
}
public Session session() {
return sessionFactory.getCurrentSession();
}
@Transactional
public boolean create(User user) {
MapSqlParameterSource params = new MapSqlParameterSource();
params.addValue("username", user.getUsername());
params.addValue("password", passwordEncoder.encode(user.getPassword()));
params.addValue("email", user.getEmail());
params.addValue("name", user.getName());
params.addValue("enabled", user.isEnabled());
params.addValue("authority", user.getAuthority());
return jdbc.update(
"insert into users (username, name, password, email, enabled, authority) values (:username, :name, :password, :email, :enabled, :authority)",
params) == 1;
}
public boolean exists(String username) {
return jdbc.queryForObject("select count(*) from users where username=:username",
new MapSqlParameterSource("username", username), Integer.class) > 0;
}
@SuppressWarnings("unchecked")
public List<User> getAllUsers() {
return session().createQuery("from User").list();
// return jdbc.query("select * from users",

}
}
Тук е моят dao-context.xml

Тук структурата на програмата:
Някакви идеи какво е неправилно в кода? Ще бъда много благодарен за всякакви идеи, защото вече съм загубил много часове, опитвайки се да разреша това.
Отговори:
0 за отговор № 1Фактът "sessionFactory", който имате, е a фабрика за създаване на потребителски сесии на SessionFactory, Фабрика, ако желаете. Той не изпълнява директно интерфейса на Hibernate SessionFactory.
Опитайте да добавите още едно боб към вашата конфигурация SessionFactory получени от тази фабрика:
<bean id="hibernateSessionFactory"
factory-bean="sessionFactory"
factory-method="newSessionFactory"/>
