Table not created with hbm2ddl.auto=update in Hibernate 5 - mysql

Question

The database table is NOT auto-created by the <property name="hbm2ddl.auto">update</property> settings in hibernate-cfg.xml, with the following combination:
Java 8 + Tomcat 8 + MySQL + Hibernate 5
Java version:
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
MySQL version:
mysql Ver 14.14 Distrib 5.6.16, for osx10.7 (x86_64) using EditLine wrapper
Tomcat version:
apache-tomcat-8.0.22
pom.xml snippets:
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>javax.persistence</artifactId>
<version>2.1.0</version>
</dependency>
<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>

<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.1-api</artifactId>

</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-c3p0</artifactId>

</dependency>
Entity class:
package com.test.entity;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import org.hibernate.annotations.GenericGenerator;
#Entity
#Table( name = "EVENTS" )
public class Event {
#Id
#GeneratedValue(generator="increment")
#GenericGenerator(name="increment", strategy = "increment")
private Long id;
private String title;
#Temporal(TemporalType.TIMESTAMP)
#Column(name = "EVENT_DATE")
private Date date;
public Event() {}
public Long getId() { return id; }
private void setId(Long id) { this.id = id; }
public Date getDate() { return date; }
public void setDate(Date date) { this.date = date; }
public String getTitle() { return title; }
public void setTitle(String title) { this.title = title; }
}
Hibernate SessionFactory initialization:
String resource = "hibernate.cfg.xml";
Configuration configuration = new Configuration();
configuration.configure(resource);
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
SessionFactory sessionFactoryCore = configuration.buildSessionFactory(serviceRegistry);
hibernate.cfg.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost:3306/test</property>
<property name="connection.username">mysqluser</property>
<property name="connection.password">******</property>
<property name="hbm2ddl.auto">update</property>
<property name="hibernate.max_fetch_depth">3</property>
<mapping class="com.test.entity.Event" />
</session-factory>
</hibernate-configuration>
HOWEVER, the table was created into MySQL database, with the following combination:
Java 8 + Tomcat 8 + MySQL + Hibernate 4
Everything same as above, except in pom.xml, I was using hibernate 4 instead of 5:
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>javax.persistence</artifactId>
<version>2.1.0</version>
</dependency>
<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
</dependency>
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.1-api</artifactId>
<version>1.0.0.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.3.11.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.3.11.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-c3p0</artifactId>
<version>4.3.11.Final</version>
</dependency>
What am I missing in Hibernate 5?

Answer 1

We faced a similar problem after upgrading to Hibernate 5.x and this was solved by changing the dialect to org.hibernate.dialect.MySQL5Dialect.

Answer 2

add <property name="javax.persistence.schema-generation.database.action">create</property> in your hibernate config file.

Answer 3

try something like that in sessionFactoryInitialisation :
StandardServiceRegistry standardRegistry = new StandardServiceRegistryBuilder().configure(configFile).build();
Metadata metadata =new MetadataSources(standardRegistry).getMetadataBuilder().build();
sessionFactory = metadata.getSessionFactoryBuilder().build();
return sessionFactory;
