Maven Project Hibernate, MySQL connection problem

I am using Intelij idea and I am tying to make a simple connection with MySQL database with hibernate following a YouTube video.
For some reason my connection does not work and I get the following Errors:

I tried to find a solution for my problem online but I didnt find something to apply to my problem.

My problem was with the MySQL dependency I changed it to version 8.0.16 and worked.

I had this problem today too, I upgraded the package of mysql-connector-java for 8.0.23 and it worked fine.

Hibernate exception in creating a table

Please help me figure out the reason of this exception and how to resolve it.
Following a youtube tutorial, I am trying to create a table named 'alien' in a MySQL database named 'abc'. I am using the Hibernate ORM tool and Maven for this but Hibernate is throwing an exception
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "create table Alien (stud_id integer not null, age integer not null, marks integer not null, stud_name varchar(255), primary key (stud_id)) type=MyISAM" via JDBC Statement

}
}

In your persistence.cfg.xml file you should change the dialect to: org.hibernate.dialect.MySQL5InnoDBDialect
Or you can simply remove it, Hibernate should be able to detect it automatically
This should let Hibernate create InnoDB tables instead of MyISAM

Try using different dialects, if you are using MySQL v8 then use these dialects org.hibernate.dialect.MySQL8Dialect or com.mysql.cj.jdbc.Driver
error is with the dialect, you can check its generating type=MyISAM instead it should be ENGINE=MyISAM
type is deprecated from MySQL version 5, ENGINE is replaced from that version, since you are using MySQL8 dependency you need to use ENGINE
so the query should like this
create table Alien (columns names) Engine=MyISAM
use InnoDB engine instead of MyISAM
try executing the query in the console or workbench

Unable to connect H2 DB with Hibernate

I am trying to create a small H2 in-memory database while using hibernate. But the table is not dispplayed in the H2 UI. I'm not sure if I need to include anything else in the configuration.
Here is the code:
Below are dependencies added for hibernate and h2 DB.
pom.xml
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.3.1.Final</version>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
<version>1.4.200</version>
</dependency>
This is the configuration XML which has all the H2 DB details.
hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 5.3//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-5.3.dtd">
<hibernate-configuration>
<session-factory>
<property name="connection.driver_class">org.h2.Driver</property>
<property name="connection.url">jdbc:h2:mem:test;DB_CLOSE_DELAY=-1</property>
<property name="dialect">org.hibernate.dialect.H2Dialect</property>
<property name="show_sql">true</property>
<property name="hbm2ddl.auto">create</property>
<mapping class="HiberDemo.Employee"/>
</session-factory>
</hibernate-configuration>
This creates the table along with the other columns.
Employee.java
package HiberDemo;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name= "emp500")
public class Employee {
#Id
private int id;
private String firstName,lastName;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
This is to store some data into the table.
StoreData.java
package HiberDemo;
import java.sql.DriverManager;
import java.sql.SQLException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.boot.Metadata;
import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import com.sun.corba.se.pept.transport.Connection;
public class StoreData {
public static void main(String[] args) throws SQLException {
StandardServiceRegistry ssr = new StandardServiceRegistryBuilder().configure("hibernate.cfg.xml").build();
Metadata meta = new MetadataSources(ssr).getMetadataBuilder().build();
SessionFactory factory = meta.getSessionFactoryBuilder().build();
Session session = factory.openSession();
Transaction t = session.beginTransaction();
Employee e1=new Employee();
e1.setId(101);
e1.setFirstName("abc");
e1.setLastName("xyz");
session.save(e1);
t.commit();
System.out.println("successfully saved");
factory.close();
session.close();
// conn.close();
}
}
This is the H2 DB UI where the table I have created is not displayed.

Check logs if temporary database is created. If so url is consoled in logs:
2020-05-28 12:20:01.280 INFO 26579 --- [ restartedMain]
o.s.b.a.h2.H2ConsoleAutoConfiguration : H2 console available at
'/h2-console'. Database available at
'jdbc:h2:mem:b9994036-2f8e-4d00-8d7d-012a270661fa'
If you try connecting using jdbc:h2:mem:b9994036-2f8e-4d00-8d7d-012a270661fa, test connection works and tables are also shown:

You might need to downgrade your version and use the below
<dependency>
<groupId> com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.193</version>
</dependency>

You must add the following two dependencies in your pom.xml
`
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
`
Then enable H2 console by adding the following line in application.properties file
spring.h2.console.enabled=true
After that run your application and open Rest endpoint "/h2-console"
Like: http://localhost:9090/h2-console/
Now copy your JDBC URL from the console
Like: Database available at 'jdbc:h2:mem:b61c56f6-93f3-4324-8b4a-4ead06f669d1'
Copy and paste in you H2 console, then click on 'Connect'
You can also configure manually everything by adding the following configuration in your application.properties file:
#---------------------------------DATABASE CONFIG-----------------------
spring.h2.console.enabled=true
spring.datasource.url=jdbc:h2:mem:person_db
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
#---------------------------------------------------------------

JPA dependency is missing. So, add below dependency.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

This is the default login to the H2 database. Confirm if your details match
Change testdb to test in the screenshot above

you may need to add the following lines to the application.properties file.
spring.datasource.url= jdbc:h2:mem:test

I had the same problem. solved after couple of days :)
these 3 ways work same as each other.
downgrade your H2 dependency. if there isn't any version mentioned maven gets the latest so you might want to explicitly mention any version below 1.4.195
as below:
<dependency>
<groupId> com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.193</version>
</dependency>
in your application properties write the full name of the database you want to connect to.
spring.datasource.url=jdbc:h2:mem:desiredName and in console use: jdbc:h2:mem:desiredName as name
by reading logs use the generated name. it differs time to time. H2 console available at '/h2'. Database available at 'jdbc:h2:mem:desiredName' this may have 16 letters after if no name is specified in application properties.
have fun.

Hibernate fails to create table in MySQL

Hibernate fails to create new table new table for Entity in MySQL eventhough property "hibernate.hbm2ddl.auto" is set to "create-drop". It also fails with "create" and "update" with the same error: org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement.
Note: Database "test" is already created and empty.
If a table named "Test" is already created (even if its empty) everything runs perfectly and table is updated.
But after hours of Stackoverflowing and Googling I am giving up. I will create empty tables previously. If someone could find a better solution would be great.
Thanks,
Runing on Ubuntu 16.04.1 64 bits with Oracle Java 1.8.0_101. MySQL Server is 5.7.15. IDE used Eclipse Neon.

Configuring tomcat, hibernate and mysql

I created a dynamic web project named HibernateSetUpTest2, jpa is marked as one of the project facets. I want to put this on a tomcat server in the future but right now I simply need to test if hibernate is working and it isn't.
I followed the MySQL DBCP Example on here (except for the jsp part):

In the project explorer of eclipse it shows a separate folder named Servers and in it is the context.xml :
<?xml version="1.0" encoding="UTF-8"?>
<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="javauser" password="javadude" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/javatest"/>
</Context>
In my src folder I wrote a Test:
package tests;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;
import entities.TestDataRow;
public class Hibernate {
public static void main(String[] args) {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("unitName");
EntityManager em = emf.createEntityManager();
EntityTransaction tx = em.getTransaction();
tx.begin();
TestDataRow t = em.find(TestDataRow.class, 1);
System.out.println(t.getFoo());
tx.commit();
em.close();
emf.close();
}
}
This uses the entity:
package entities;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="testdata")
public class TestDataRow {
#Id
private int id;
private String foo;
private int bar;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFoo() {
return foo;
}
public void setFoo(String foo) {
this.foo = foo;
}
public int getBar() {
return bar;
}
public void setBar(int bar) {
this.bar = bar;
}
}
When I run the test as a java application it throws errors:

What am I doing wrong?

Your code itself looks fine (can't tell for sure but nothing seems to be seriously wrong) but you have a huge issue with your test itself:
It is a standalone test.
What the errormessage is telling you:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property
Basically means, that while attempting to lookup the JNDI variable (your DB resource definition) it had nowhere to "look". There is no context in your test. That is why it failed.
The standard ways of dealing with this kind of problem are:
either programmatically creating a context
or - just for the sake of the test - inserting a DB resource definition via simple autowiring, and not using JNDI at all.
Example and source for further ideas can be found here:
Setting up JNDI Datasource for uni testing

I think you need some initialisation or its a lack of configuration
