Unable to locate persister

I have the following problem when i try to do the findCliente method. I have the class Cliente in the package model and when i run the findCliente controller I get this exception here. I don't know where I'm wrong because I don't have much skill with JPA and Spring Suite. Can someone tell me how to fix this exception?

In order to solve this problem you have two options. You can choose either of which .
1- you must have all you entity classes declared in you hibernate configuration file.
for this you must add you entity classes specially "Cliente" in hibernate.cfg.xml file
like this :
<mapping class="entity.Client"/>
or
2-another way is adding this entity to session configuration like this :
SessionFactory factory = new Configuration().configure("hibernate.cfg.xml") .addAnnotatedClass(Cliente.class) .buildSessionFactory();

Note The full stack trace of the root cause is available in the server logs.

Your actual error is this:
The server time zone value 'Malay Peninsula Standard Time' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specifc time zone value if you want to utilize time zone support.
As it says, you either need to configure your server with the correct timezone. Or set the "serverTimezone" property on your JDBC driver URL. Example:
jdbc:mysql://localhost/db?serverTimezone=UTC

UnsatisfiedDependencyException: error creating bean

I'm creating an ecommerce website using springMVC and hibernate. How ever I'm getting the following errors while running the junit test case. I'd really appreciate any help provided for the same.

But I am not creating the test case for either of them I don't know why it is showing error for these entities. I'm only creating the test case for Account entity so I'll share that as well.

You have to annotate your test class with #RunWith(SpringJUnit4ClassRunner.class) so Spring can inject your beans to your tests.
Try this:
#RunWith(SpringJUnit4ClassRunner.class)
public class AccountDaoTest {
//...
}
I believe you can inject your dao directly, once you indicated it as a repository, so you can inject your dao instead of AnnotationConfigApplicationContext in your test class:
#Autowired
#Qualifier("userDao")
private AccountDaoImpl userDao;
And finally, make sure you have spring-test in your pom.xml:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<scope>test</scope>
</dependency>

I haven't got a clue about this issue.
Update
DAO class:
package sbk.spring.simplejc.dao;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import sbk.spring.simplejc.entity.Team;
#Repository
public class HibTeamDAO implements TeamDAO {
#Autowired
private SessionFactory sessionFactory;
public void addTeam(Team team) {
sessionFactory.getCurrentSession().save(team);
}
public void updateTeam(Team team) {
sessionFactory.getCurrentSession().update(team);
}
#SuppressWarnings("unchecked")
public List<Team> listTeams() {
return sessionFactory.getCurrentSession().createQuery("from Team").list();
}
#SuppressWarnings("unchecked")
public Team getTeamById(Integer teamID) {
Session session = sessionFactory.getCurrentSession();
List<Team> listTeam = session.createQuery("from Team t where t.id = :teamID")
.setParameter("teamID", teamID)
.list();
return listTeam.size() > 0 ? (Team)listTeam.get(0) : null;
}
public void removeTeam(Integer teamID) {
Team team = (Team) sessionFactory.getCurrentSession().load(Team.class, teamID);
if(team != null){
sessionFactory.getCurrentSession().delete(team);
}
}
#Override
public Integer count() {
return (Integer) sessionFactory.getCurrentSession().createQuery("select count(t) from Team t").uniqueResult();
}
}
TeamController class:
package sbk.spring.simplejc.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import sbk.spring.simplejc.service.ITeamService;
#Controller
public class TeamController {
#Autowired
ITeamService service;
#RequestMapping(value="/")
public ModelAndView goToHelloPage() {
ModelAndView view = new ModelAndView();
view.addObject("teamList", service.listTeams());
return view;
}
}
Update
Now I got rid from this problem by changing DAO method from
return sessionFactory.getCurrentSession().createQuery("from Team").list();
to
return sessionFactory.getCurrentSession().createQuery("from sbk.spring.simplejc.entity.Team").list();
But received another issue: every query return null despite of existing rows in Team table.
Update
Finally I noticed warning messages:
Feb 15, 2014 7:01:05 PM org.hibernate.hql.internal.QuerySplitter concreteQueries
WARN: HHH000183: no persistent classes found for query class: from sbk.spring.simplejc.entity.Team
Update
At least I've sorted out this issue by adding next row of code in dataSource bean definition in WebAppConfig:
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
sessionFactoryBean.setDataSource(dataSource());
sessionFactoryBean.setAnnotatedClasses(new Class[]{Team.class});//new row!!!
sessionFactoryBean.setPackagesToScan(env.getRequiredProperty(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN));
sessionFactoryBean.setHibernateProperties(hibProperties());
return sessionFactoryBean;
}

In my case it was because I didn't have the hibernate packagesToScan property. I see that you have it. May be this comment will be useful for someone who missed it.

"No, in this instance I've got org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: * near line 1, column 8 [select * from Team] – Sobik Feb 15 at 10:29"
Instead "Select * from Team" try write "from Team". Because Hibernate works with java entity.
