I'm trying to use Spring on top of JPA with a Hibernate implementation. I'd like to use Spring for at least Annotation, Autowiring & Transaction management. I keep running into the below issue though. Any help would be greatly appreciated!
My GenericDAO Implementation:
package gov.cms.cicdim.cpc.data.dao;
import java.io.Serializable;
import java.lang.reflect.ParameterizedType;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
@Repository
@Transactional
public abstract class GenericDAO<K, T extends Serializable>
implements IGenericDAO<K, T>
{
protected Class<T> entityClass;
@PersistenceContext
protected EntityManager entityManager;
@Autowired
public GenericDAO()
{
ParameterizedType genericSuperclass = (ParameterizedType) getClass().getGenericSuperclass();
this.entityClass = (Class<T>) genericSuperclass.getActualTypeArguments()[1];
}
public T findOne(K id)
{
if(isEmpty(id)) { return null; }
return this.entityManager.find(entityClass, id);
}
public List<T> findAll()
{
return this.entityManager.createQuery("from " + entityClass.getName()).getResultList();
}
public void create(T entity)
{
this.entityManager.persist(entity);
this.entityManager.close();
}
public void update(T entity)
{
this.entityManager.merge(entity);
this.entityManager.flush();
this.entityManager.close();
}
public void delete(T entity)
{
this.entityManager.remove(entity);
this.entityManager.close();
}
public void deleteById(K id)
{
T entity = findOne(id);
delete(entity);
}
/**
* Utility method to determine if objects is empty or all elements are null for optimization purposes.
*
* @param objects the objects
* @return true, if is empty
*/
protected boolean isEmpty(Object...objects) {
if(objects.length == 0) {
return true;
}
for(Object o : objects) {
if(o != null) {
return false;
}
}
return true;
}
}
The DAO itself:
package gov.cms.cicdim.cpc.data.dao;
import gov.cms.cicdim.cpc.data.model.Practice;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
/**
* The Class PracticeDAO for CRUD operations for Practice data.
*/
@Repository
@Transactional
public class PracticeDAO extends GenericDAO< String, Practice>
{
public PracticeDAO(){}
/** The Constant logger. */
private static final Log logger = LogFactory.getLog(PracticeDAO.class);
}
The test DAO: (In src/test/java)
package gov.cms.cicdim.cpc.data.dao;
import gov.cms.cicdim.cpc.data.model.Practice;
import java.util.List;
import junit.framework.AssertionFailedError;
import junit.framework.TestCase;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/applicationContext.xml")
@Transactional
public class PracticeDAOTest extends TestCase
{
@Autowired
public PracticeDAO testPracticeDAO;
public void setPracticeDAO(PracticeDAO testPracticeDAO) {
this.testPracticeDAO = testPracticeDAO;
}
boolean doit = true;
@Test
public void testCreatePracticeDAO(){
if(doit){
Practice practice = generatePractice();
String porg = practice.getParentOrgName();
String pid = practice.getPracticeId();
//create
try {
testPracticeDAO.create(practice);
String pratice_id = testPracticeDAO.findOne(pid).getPracticeId();
assertEquals("Practice id check", pid, pratice_id);
} catch (Exception e) {
e.printStackTrace();
throw new AssertionFailedError("Practice Save failed");
}
// test update
try{
practice.setSiteName("baltimore");
if(testPracticeDAO.findOne(pid) !=null){
testPracticeDAO.update(practice);
String site_Name = testPracticeDAO.findOne(pid).getSiteName();
assertEquals("Practice Site check", "baltimore", site_Name);
}
} catch(Exception e){
e.printStackTrace();
throw new AssertionFailedError("Practice update failed!");
}
}
