Why does hibernate drops foreing key constraint before creating tables?

Here is my simple hibernate.cfg.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost/UserDB</property>
<property name="connection.username">root</property>
<property name="connection.password"></property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>
<!-- Enable Hibernate's automatic session context management -->
<property name="current_session_context_class">thread</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create-drop</property>
<!-- Mapping files -->
<mapping class="com.stackoverflow.model.Person" />
<mapping class="com.stackoverflow.model.Phone" />
</session-factory>
Here is simple Person entity:
#Entity(name = "Person")
public class Person {
#Id
#GeneratedValue
private Long id;
public Person() {
}
}
Here is simple Phone entity:
#Entity(name = "Phone")
public class Phone {
#Id
#GeneratedValue
private Long id;
#Column(name = "`number`")
private String number;
#ManyToOne(cascade=CascadeType.ALL,optional=false)
#JoinColumn(name = "person_id",
foreignKey = #ForeignKey(name = "PERSON_ID_FK")
)
private Person person;
public Phone() {
}
public Phone(String number) {
this.number = number;
}
public Long getId() {
return id;
}
public String getNumber() {
return number;
}
public Person getPerson() {
return person;
}
public void setPerson(Person person) {
this.person = person;
}
}
Here is junit test class that tries to save this relationship into database:
public class TestManyToOne {
private static SessionFactory sessionFactory;
private Session session;
#BeforeClass
public static void setUp() throws Exception {
// A SessionFactory is set up once for an application!
final StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure("hibernate.cfg.xml")
.build();
try {
sessionFactory = new MetadataSources(registry).buildMetadata().buildSessionFactory();
} catch (Exception e) {
// The registry would be destroyed by the SessionFactory, but we had
// trouble building the SessionFactory
// so destroy it manually.
StandardServiceRegistryBuilder.destroy(registry);
System.out.println("Exception\n" + e);
}
assertNotNull(sessionFactory);
}
#AfterClass
public static void tearDown() throws Exception {
sessionFactory.close();
}
#Before
public void beforeEach() {
session = sessionFactory.getCurrentSession();
session.beginTransaction();
}
#After
public void afterEach() {
session.getTransaction().commit();
session.close();
}
#Test
public void testSave() {
Person person = new Person();
Phone phone1 = new Phone("93283287832");
Phone phone2 = new Phone("0987654321");
phone1.setPerson(person);
phone2.setPerson(person);
session.save(phone1);
session.save(phone2);
}
}
It has only one #Test method called testSave. When I run it on just created database I get error :

How to tell hibernate do not drop foreign key constraint before creating tables?
Thank you.

I didn't believe it but the problem was that connection pool size was set to 1. After I set it to ten
<property name="connection.pool_size">10</property>
junit test runs succesfully but the error didn't disappear. It is ignored by eclipse.

Hibernate 5: Mapping by annotation doesn't work and throws MappingException (unknown entity)

I have already checked solutions for the problem, but it did not help.
I am practicing Spring+Hibernate. Previously I have mapped entities by .xml file. But now I tried to do it by annotations cause it looks more comfortable. But unfortunately, I got
Unknown entity: milkiv.easyword.models.UserRole; nested exception is org.hibernate.MappingException: Unknown entity: milkiv.easyword.models.UserRole
So I have the next model file:
package milkiv.easyword.models;
import java.io.Serializable;
import java.util.Objects;
import javax.persistence.*;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.NotBlank;
#Entity (name = "UserRole")
#Table(name = "user_role")
public class UserRole implements Serializable{
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
#Column(name = "role_id", updatable = false, unique = true)
private int roleId;
#NotBlank(message = "Email field can not be empty or missed.")
#Size(min = 3, max = 59, message = "Email field must have from 5 to 128 symbols.")
#Column(name = "name", nullable = false, unique = true)
private String name;
public UserRole() {
}
public int getRoleId() {
return roleId;
}
public void setRoleId(int roleId) {
this.roleId = roleId;
}
public String getName() {
return name;
}
public void setName(String name) {
//INFO: SPRING REQUIRE NAME ROLES IN FORMAT - ROLE_rolename
this.name = "ROLE_".concat(name);
}
#Override
public int hashCode() {
return (name.hashCode()*31+roleId)*31;
}
#Override
public boolean equals(Object obj) {
if (this == obj) {
return true;
}
if (obj == null) {
return false;
}
if (getClass() != obj.getClass()) {
return false;
}
final UserRole other = (UserRole) obj;
if (this.roleId != other.roleId) {
return false;
}
return Objects.equals(this.name, other.name);
}
}

The message is clear, but the cause of it - no.
Please if anyone have any ideas can you help me? I will appreciate any help.
Thank's in advance.
EDIT: I use Hibernate 5.0.1.Final version.
EDIT: Tried this one. Also doesn't work for me:
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="annotatedClasses">
<list>
<value>milkiv.easyword.models</value>
</list>
</property>
<property name="configLocations">
<value>classpath:resources/hibernate.cfg.xml</value>
</property>
</bean>

Hibernate does not know about your annotated class, you need to tell hibernate where it is, with this property in the session factory xml:
<mapping package="milkiv.easyword.models"/>
or directly a class:
<mapping class="milkiv.easyword.models.UserRole"/>
Check out the docs.

Hibernate NESTED EXCEPTION

I have a problem with hibernate NESTED EXCEPTION. Couple of hours after deploying the app on server, these errors start showing up. I think the problem is with mysql connection which expires. Tomcat 7, show me that application has memory leaks too.
Sample dao class(sometimes app have orm query, sometimes sqlquery)
public List<Object[]> getPckey(String labId){
SessionFactory sessionFactory = null;
Session session = null;
Transaction tx = null;
try{
sessionFactory = HibernateAnnotationUtil.getSessionFactory();
session = sessionFactory.getCurrentSession();
tx = session.beginTransaction();
String asd = "SELECT pcKey, regDate, pcKeyStatus, unRegDate FROM PcKey WHERE idLaboratory = :laboratoryId AND pcKey IS NOT NULL ORDER BY pcKeyStatus DESC, unRegDate";
Query query = session.createQuery(asd);
query.setParameter("laboratoryId", labId);
List<Object[]> results = query.list();
tx.commit();
return results;
}catch(Exception e){
e.printStackTrace();
return null;
} finally {
if (session != null) {
session.close();
}
}
}
HibernateAnnotationUtil class
public class HibernateAnnotationUtil {
private static SessionFactory sessionFactory;
private static SessionFactory buildSessionFactory() {
try {
// Create the SessionFactory from hibernate-annotation.cfg.xml
Configuration configuration = new Configuration();
configuration.configure("hibernate-annotation.cfg.xml");
System.out.println("Hibernate Annotation Configuration loaded");
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
System.out.println("Hibernate Annotation serviceRegistry created");
SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);
return sessionFactory;
}
catch (Throwable ex) {
System.err.println("Initial SessionFactory creation failed." + ex);
ex.printStackTrace();
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
if(sessionFactory == null) sessionFactory = buildSessionFactory();

. . . .
</session-factory>
OR use Apache DBCP Connection Pool
For details about Connection Pooling you can read this Hibernate: What is the connection pool and why is the default one unsuitable for production?

According to stack trace, your dao is throwing an exception :
at
com.want.ecdlejb.dao.CheckIsPcExistDao.isPcExist(CheckIsPcExistDao.java:32)
And as is see, in getPcKey() method, when exception occurs, you only print stack trace in catch block, you have to rollback your transaction here tx.rollback() (in your catch block), otherwise, this will lead to connection leak.
You should also (as suggest below) think to use a connection pool and configure it correctly.
I hope that this could help !
Regards

Spring 3 with Hibernate 4--unit test failure with No Session found for current thread

I have used Spring and Hibernate for years, but this is my first project using Spring 3 and Hibernate 4.
I set up the Model class such:
#Entity
#Table(name = "DICTIONARY_ENTRY", uniqueConstraints = #UniqueConstraint(columnNames = {
"DICTIONARY_UUID", "ANAGRAM", "WORD" }))
public class DictionaryEntry extends Pojo implements
Comparable<DictionaryEntry> {
#Column(name = "ANAGRAM", nullable = false)
private String anagram;
#Column(name = "WORD", nullable = false, unique = true)
private String word;
#Column(name = "DEFINITION", nullable = false)
private String definition;
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "DICTIONARY_UUID", referencedColumnName = "UUID", nullable=false)
private Dictionary dictionary;
#OneToMany(fetch = FetchType.LAZY, mappedBy = "fromEntry")
/*package*/ Set<CrossReference> fromReferences;
#OneToMany(fetch = FetchType.LAZY, mappedBy = "toEntry")
/*package*/ Set<CrossReference> toReferences;
Per the directions in the Spring manual, I then set up my DAO and inject in an instance of org.springframework.orm.hibernate4.LocalSessionFactoryBean. Then I call getSession() which is:
/**
* Get the current session for a hibernate query
* #return the current session
*/
protected Session getSession(){
return sessionFactory.getCurrentSession();
}
I then run my unit test, inject in my session factory and run this method:
object = (T) getSession().save(object);
Which throws:

There are two things you need to modify:
Firstly, you are using Hibernate for persistence, so you need to use HibernateTransactionManager instead of DataSourceTransactionManager.
<!-- Transaction Configuration For All Services (including Hibernate and MyBatis)-->
<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- Transaction: enable annotation-driven transaction -->
<!--Put #Transactional on service impl instead of service interface-->
<tx:annotation-driven transaction-manager="txManager" proxy-target-class="true"/>
Secondly, you are using Hibernate 4.x, so you need to configure current session context class like this:
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop>
For information, reference http://blog.springsource.org/2012/04/06/migrating-to-spring-3-1-and-hibernate-4-1/
I hope you pass it

I had the same problem in my junit test in a spring 3 application with hibernate 3.6.
When the application runs on application server, the sessions is managed with session filter:
<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
But when run junit it is not loaded, you have to simulate it in your test.
One solution as suggested is to use #TransactionConfiguration or extending AbstractTransactionalJUnit4SpringContextTests but it not works if you have a Service Layer classes annotated with #Service #Transactional and you call it several times in your test.
I solved as following, according to this post:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = {"classpath:context.xml"})
public class JUnitTestBase extends AbstractJUnit4SpringContextTests {
#Autowired
protected Log logger;
#Autowired
protected SessionFactory sessionFactory;
protected FlushMode flushMode = FlushMode.MANUAL;
#Before
public void setUp() throws Exception {
Session session = getSession(this.sessionFactory);
TransactionSynchronizationManager.bindResource(sessionFactory,new SessionHolder(session));
logger.debug("Hibernate session is bound");
}
#After
public void tearDown() throws Exception {
SessionHolder sessionHolder = (SessionHolder) TransactionSynchronizationManager.unbindResource(sessionFactory);
closeSession(sessionHolder.getSession(), sessionFactory);
logger.debug("Hibernate session is closed");
}
protected void closeSession(Session session, SessionFactory sessionFactory) {
SessionFactoryUtils.closeSession(session);
}
protected Session getSession(SessionFactory sessionFactory) throws DataAccessResourceFailureException {
Session session = SessionFactoryUtils.getSession(sessionFactory, true);
FlushMode flushMode = this.flushMode;
if (flushMode != null) {
session.setFlushMode(flushMode);
}
return session;
}
}

I think your test may be missing TransactionConfiguration annotation. Try the following -
#TransactionConfiguration(transactionManager="txManager")
Alternatively, you could change your bean definition for transaction manager as follows -
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="testDatabase"/>
By default spring tries to find 'transactionManager' bean.
