@ContextConfiguration in Spring 3.0 give me No default constructor found
- by atomsfat
I have already do the test using AbstractDependencyInjectionSpringContextTests and it works but in spring 3 it is deprecated, so I decided to try @ContextConfiguration but spring say that default constructor is not found, I check and the class doesn't have any constructor.
If I use this test spring give the object.
package atoms.portales.servicios.impl;
import atoms.portales.model.Cliente;
import atoms.portales.servicios.ClienteService;
import java.util.List;
import javax.persistence.EntityManager;
import org.springframework.test.AbstractDependencyInjectionSpringContextTests;
/**
*
* @author tsalazar
*/
public class ClienteServiceImplDeTest extends AbstractDependencyInjectionSpringContextTests{
private ClienteService clienteService;
public ClienteService getClienteService() {
return clienteService;
}
public void setClienteService(ClienteService clienteService) {
this.clienteService = clienteService;
}
public ClienteServiceImplDeTest(String testName) {
super(testName);
}
@Override
protected String[] getConfigLocations() {
return new String[]{"PersistenceAppCtx.xml", "ServicesAppCtx.xml"};
}
/**
* Test of buscaCliente method, of class ClienteServiceImplDeTest. */
public void testBuscaCliente() {
System.out.println("=======================================");
System.out.println("buscaCliente");
String nombre = "";
System.out.println(clienteService);
System.out.println("=======================================");
}
}
But if I use this, spring say that default constructor is not found.
package atoms.config.portales.servicios.impl;
import atoms.portales.model.Cliente;
import atoms.portales.servicios.ClienteService;
import org.junit.runner.RunWith;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.transaction.annotation.Transactional;
/**
*
* @author tsalazar
*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/PersistenceAppCtx.xml", "/ServicesAppCtx.xml"})
@TransactionConfiguration(transactionManager = "transactionManager")
@Transactional
public class ClienteServiceImplTest {
@Autowired
private ClienteService clienteService;
/**
* Test of buscaCliente method, of class ClienteServiceImpl. */
@Test
public void testBuscaCliente() {
System.out.println("=======================================");
System.out.println("buscaCliente");
System.out.println(clienteService);
System.out.println("=======================================");
}
}
This how I do the implementacion:
package atoms.portales.servicios;
import atoms.portales.model;
/**
* Una interface para obtener clientes, con sus surcursales, servicios, layouts
* y contratos. Tambien soporta operaciones CRUD.
* @author tsalazar
*/
public interface ClienteService {
/**
* Busca clientes a partir del nombre
* @param nombre
*/
public Cliente buscaCliente(String nombre);
}
the implemetacion
package atoms.portales..servicios.impl;
import atoms.portales.model.Cliente;
import atoms.portales.servicios.ClienteService;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
/**
* A JPA-based implementation.Delegates to a JPA entity manager to issue data access calls
* against the backing repository. The EntityManager reference is provided by the managing container (Spring)
* automatically.
*/
@Service("clienteSerivice")
@Repository
public class ClienteServiceImpl implements ClienteService {
public ClienteServiceImpl() {
}
private EntityManager em;
@PersistenceContext
public void setEntityManager(EntityManager em) {
this.em = em;
}
@Transactional(readOnly = true)
public Cliente buscaCliente(String nombre) {
Cliente cliente = em.getReference(Cliente.class, 1l);
return cliente;
}
}
spring configuration:

This is the error that give me:
