Unable to locate persister

Unable to locate persister - java

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();

#SequenceGenerator throws After saving the identifier must not be null! when value of id not passed in h2

I am using spring boot with h2 database when using a sequence and using #SequenceGenerator doesn't seem to be generating the value for the primary key. I want to generate the value of Id by default and then update the values into the database.
Here are the details of my class.

You are adding lot of dependencies which you don't need. And when you add a dependency that you don't need, spring boot tries to guess the type of your application and configures accordingly.
I also recommend reading Spring data JPA vs Spring Data JDBC as both are mixed.

public CardHolder addCardHolder(CardHolder cardHolder) {
return cardHolderRepository.save(cardHolder);
}
#Override
public void rentBook(RentBookRequest bookRequest) throws Exception {
CardHolder cardHolder = new CardHolder();
cardHolder.setFirstName(bookRequest.getFirstName());
cardHolder.setLastName(bookRequest.getLastName());
cardHolder.setCardNumber(bookRequest.getCardNumber());
CardHolder saved = cardHolderDAO.addCardHolder(cardHolder);
Rental rental = new Rental();
rental.setBook_id(bookRequest.getBookId());
rental.setCardHolder_id(saved.getId());
rentalDAO.addRental(rental);

No Session with spring.jpa.open-in-view=false

I have a Spring Boot 2.1 app with a simple rest controller, service tier, and data tier. I am attempting to disable spring.jpa.open-in-view as I want to manage the loading of my collections, etc. My problem seems to be when I disable open-in-view, I can't get anything back in my controller including simple properties including Strings.

public List<Item> findAll(String building) {

and the service super class:

And the controller:

import org.springframework.web.bind.annotation.*;
import java.security.Principal;
import java.util.Collections;
import java.util.List;
import java.util.Optional;
import java.util.stream.Stream;
#RestController
#RequestMapping("/items")
#Slf4j
public class ItemController extends BaseController {
private final ItemService service;
public ItemController(ItemService itemService, AdminUserService adminUserService) {
super(adminUserService);
this.service = itemService;
}
#GetMapping("/all")
#Secured("CAFE_MANAGER")
public List<Item> all(Principal principal) {
return getLocation(principal)
.map( service::findAll )
.orElse( Collections.emptyList() );
}
#GetMapping("/single/{itemId}")
#Secured("CAFE_MANAGER")
public Item getSingle(Principal principal, #PathVariable("itemId") long id) {
final Optional<String> location = getLocation(principal);
location
.flatMap( l -> service.get(id) )
.ifPresent( item -> {
log.info("Item.toString {}", item);
});
return location
.flatMap( l -> service.get(id) )
.filter( item -> item.getBuilding() != null && item.getBuilding().equalsIgnoreCase(location.orElse(null)) )
.orElse( null );
}
}
So what am I missing, why can't I pull back basic properties, there are no collections in the Item class and it about as simple as they come. I see that I'm getting a HibernateProxy wrapped object back and when I attempt to call getBuilding is when it appears to be failing, even though building is just a simple string. This is all before Jaskson is attempting to serialize the object to put it over the wire. Thanks!

I'am traning to this example...

You use org.springframework.orm.hibernate4.HibernateTransactionManager for Hibernate 4. This class using TransactionContext from Hibernate 4.
Looks like you use Hibernate 5. Just change
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
to this
import org.springframework.orm.hibernate5.HibernateTransactionManager;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;
You need to use corresponding Spring libraries of course. For an example 4.2.4.RELEASE.
