how to save data with save method of jpa Repository
Question
While adding the entity from service implemented class to Repository interface , it showing successful message but data does not inserted to the database i call the save(entity) method from JpaRepository interface . it does not show any error message instead of that it showing record inserted successfully message .
Controller --- >>.
@Controller
@RequestMapping("/cart")
public class CartController {
@Autowired
CartService cartServices;
/**
* Get All records in Cart
*
* @return All Cart List
*/
@RequestMapping(value = "/list", method = RequestMethod.GET)
public @ResponseBody List<Cart> getCart() {
List<Cart> cartList = null;
try {
cartList = cartServices.getCartList();
if(cartList.isEmpty())
{
System.out.println("List is empty ");
}
} catch (Exception e) {
e.printStackTrace();
}
return cartList;
}
/**
* Add Cart
*
* @param representative
* @return Status
*/
@RequestMapping(value = "/create", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody Status addCart(@RequestBody Cart cart) {
System.out.println("i m from jpa controller");
try {
cartServices.save(cart);
return new Status(1, "Cart added Successfully !");
} catch (Exception e) {
// e.printStackTrace();
return new Status(0, e.toString());
}
}
Service Implemented class------>>>>
@Service
public class CartServiceImpl implements CartService {
@Inject
CartRepository cartRepository;
/**
* Get All Cart
*
* @throws Exception
* @return All Cart List
*/
@Override
@Transactional
public List<Cart> getCartList() throws Exception {
// TODO Auto-generated method stub
return cartRepository.findAll();
}
/**
* Add Cart
*
* @param cart
* @throws Exception
* @return Boolean
*/
@Override
@Transactional
public Cart save(Cart cart) throws Exception {
System.out.println("i m from jpa Service");
Cart cart1 = cartRepository.save(cart);
return cart1;
}
Repository Interface-------->>>>
package com.xptraining.repository;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import com.xptraining.model.Cart;
@Repository
public interface CartRepository extends JpaRepository<Cart, Long>
{

Did you add below line in your rest.xml
<repositories base-package="com.acme.repositories" />
If not try with adding above line. It will setup Spring to create proxy instances for those interfaces.

You have defined both Hibernate Session factory and JPA Entity manager in your rest.xml. Use only one. Refer the below answer.
