I got my application running with using a local h2 database. Now I want to connect it to an online mysql database. But when trying to start the connection, I get com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure several times and in addition the following error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

And this to my application.properties:

spring.datasource.name=dbname
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.ddl-auto=update
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
When changing from h2 to mysql I did not do any changes on my sourcecode since I'm implementing the CrudRepository that should also work with mysql.
Could you give me some hints what might be missing? I already checked similar questions here on stackoverflow, but after adding several solution approaches (e.g. adding the hibernate.dialect and driver-class-name) my application is still not working.
# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
You need to modify the dialect based on the version of mysql running.
MySql 5.5 - org.hibernate.dialect.MySQL55Dialect
MySql 5.7 - org.hibernate.dialect.MySQL57Dialect
MySql 8 - org.hibernate.dialect.MySQL8Dialect
You can check MySql version using this query
SHOW VARIABLES LIKE "%version%";
and check InnoDB version
Thanks!! I've head the same probleme and resolve it using your answer:
1) First I chekcked MySql version with
SHOW VARIABLES LIKE "%version%";
2) Then modified the dialect using the right one:
MySql 5.5 - org.hibernate.dialect.MySQL55Dialect
MySql 5.7 - org.hibernate.dialect.MySQL57Dialect
MySql 8 - org.hibernate.dialect.MySQL8Dialect
And it worked!
Replace these properties into your app.prop file.
# Connection url for the database "netgloo_blog"
spring.datasource.url = jdbc:mysql://localhost:3306/your_db_name?useSSL=false
# Username and password
spring.datasource.username = username
spring.datasource.password = password
# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
# ===============================
# = JPA / HIBERNATE
# ===============================
# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager).
# Show or not log for each sql query
spring.jpa.show-sql = true
# Hibernate ddl auto (create, create-drop, update): with "update" the database
# schema will be automatically updated accordingly to java entities found in
# the project
spring.jpa.hibernate.ddl-auto = update
# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
# Spring data jpa Auditor <jpa:auditing auditor-aware-ref="customAuditorAware"/>
# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
Datasource url should be:
spring.datasource.url=jdbc:mysql://localhost/database?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
Just add the following line to your project property file.
spring.jpa.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
I know this is an old thread. Just updating this in case someone else is facing the same issue.
As written in the error message - org.hibernate.exception.GenericJDBCException: Unable to open JDBC Connection for DDL execution, this is a Generic JDBC exception and unlike what it sounds, this does not always mean that it is unable to establish a connection.
In my case, I was using a different datasource with H2 for unit testings and all. What I found out is that I gave a wrong classpath in H2 DB schema creation command. This same error message is also generated if there is nay query error while table creaion in while H2 start up.
Best possible solution for this is to just run it in debug mode and find out what is causing this issue.

I have a java webapp with spring mvc, mybatis, jndi and tomcat
Additionally, On Tomcat context.xml, I defined:
<Resource auth="Container"
driverClassName="com.mysql.jdbc.Driver"
maxIdle="100" maxTotal="100"
name="jdbc/dbExample"
password="dbpass"
type="javax.sql.DataSource"
url="jdbc:mariadb:sequential://192.1.1.12,192.1.1.13,192.1.1.14:3306/dbExample"
username="dbuser"/>
Also, in pom file I have the following dependency:
<dependency>
<groupId>org.mariadb.jdbc</groupId>
<artifactId>mariadb-java-client</artifactId>
<version>1.7.6</version>
</dependency>
The database is mariadb galera cluster multimaster.
Then when I test the web app I got the following error:
Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: Cannot load JDBC driver class 'com.mysql.jdbc.Driver'] with root cause java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
What can I do?
I am creating an application using Spring Boot JPA, I am using MySQL as a database.
Following is my application.properties
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/mydb
spring.datasource.username=root
spring.datasource.password=
spring.jpa.database-platform=org.hibernate.dialect.MySQL8Dialect
I have added following dependencies

*************************** APPLICATION FAILED TO START
Description:
Failed to configure a DataSource: 'url' attribute is not specified and
no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following: If you want an embedded database (H2, HSQL or
Derby), please put it on the classpath. If you have database settings
to be loaded from a particular profile you may need to activate it (no
profiles are currently active).
Spring Boot auto-configuration tries to configure the beans automatically based on the dependencies added to the classpath. Since you have the JPA dependency on your classpath, Spring Boot tries to automatically configure a JPA DataSource. The problem is, you haven’t given Spring the complete information it needs to perform the auto-configuration.
Add this missing property to your application.properties file, so that spring can autoconfigure
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
Another way you can define your data source programmatically, by using the utility builder class DataSourceBuilder. For that you need to provide the database URL, username, password, and the SQL driver information to create your data source:
#Configuration
public class DatasourceConfig {
#Bean
public DataSource datasource() {
return DataSourceBuilder.create()
.driverClassName("com.mysql.cj.jdbc.Driver")
.url("jdbc:mysql://localhost:3306/myDb")
.username("root")
.password("pass")
.build();
}
}
I had the same problem, I resolved it by doing right click on the project, maven/update project, then you should select your project and accept.
I had this problem too. My solution is : open module settings,and select resources,and right click it ,and select "Test Resources". Then it's solved.
Spring Autoconfigure looks for 2 properties to load the appropriate driver,
spring.datasource.driverClassName (in this case the value would be 'com.mysql.cj.jdbc.Driver' from MySQL connector 4.4.1.3 onwards)
spring.datasource.url (in this case it is jdbc:mysql://localhost:3306/mydb)
Actually Spring Autoconfigure just need spring.datasource.url and it can derive the driver class name from there.
Your application organization looked like :
Commons
->
Module1
Commons was a parent to Module1.
I had created a BaseEntity having JPA annotations in my commons module. The commons dependency was specified as
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
Once I added the provided
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<scope>provided</scope>
</dependency>
The issue got resolved for me. Unfortunately
change:
spring.datasource.url=jdbc:mysql://localhost:3306/mydb
to:
spring.datasource.url=jdbc:mysql://${MYSQL_HOST:localhost}:3306/mydb
It was some mistake in my configuration which I couldn't detect, I re-created same project and things started working
i'm trying to port my web-app from windows (using xampp for apache+mysql) to ubuntu (using docker container, so i have two containers: one with tomcat and another one with mysql.. they're linked).
Related to this question, i can't reach my sql container. It's creted from this image.
Tomcat container is created from official tomcat:8.0 image.
The two container are linked via a bridge docker network created.
It's a web-app that provides login+register service with checking user's presence in db.
I have to tell that on windows all works well.

After i insert my credential, i click on "login"; then there is a servlet named "UserSessionServlet" that checks if in the db is present an user with that credential; the error appairs when i click login, because UserSessionServlet return http 500 error.
[Edit] On tomcat container, i saw that logs tell me:

But all these classes exist, under opt/tomcat/webapps/AtApplicazione1/WEB-INF/classes/com/AtBoscoCastellano/some/paths.
I have to tell that i've not modified my tomcat container from official image (tomcat:8.0), so i can't know if it's configured for hibernate or not.
My war is structured as follows: three folders (META-INF, WEB-INF, template) and a file (.DS_Store). Because of my exception is :java.lang.NoClassDefFoundError: Could not initialize class com.ATBoscoCastellano.Util.HibernateUtil.HibernateUtil , in the war, this class is under WEB-INF/classes/com/ATBoscoCastellano/Util/HibernateUtil/ ... in which there is HibernateUtil .class and .java.
When i cmd java/javac -version on my tomcat container, its output is:
root#a26ff8018f3f:/opt/tomcat# java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)

[re-edit]: in my first requests, catalina logs says java.net.ConnectException: Connection refused; then, from the second request, it says to me always the same error.
[EDIT] now i'm using a new mysql container, named mysql-phpmyadmin from this image. I've linked tomcat container to this (new) container,; if i point, in the hibernate.cfg.xml, to localhost:PORT_MYSQL/AT_DB --> connection refused in tomcat log. If i point to mysql-phpmyadmin:PORT/AT_DB, tomcat logs says:

I have to tell that, in config file within mysql container, there is bind_address 0.0.0.0
I think I have an idea why you are getting this exception. You are running 2 containers,
mysql container for data base
Tomcat container
Surely, your exception is due to static variable initialization exception,
public static final SessionFactory sessionFactory = buildSessionFactory();
Also, your property file has few problems,
connection.url should be hibernate.connection.url
You have mentioned your mysql hostname as localhost but it is running in another container. You should change it to "mysql" if you have named your mysql container as "mysql"

Clearly shows that your either
Mysql is not runnning. Check by making a connection from sql client like squirrel.
Tomcat container can't connect to mysql container. Check a quick ping by doing
docker exec tomcat ping mysql
Took me a while to deploy this application. I have solved the problem you have asked in this question. The primary problem was that mysql was not reachable from tomcat container. Also, the port specified was also not correct. Following is hibernate.cfg.xml,
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>

<property name="hibernate.connection.username">root</property>
<property name="connection.password">lxit</property>
....rest of configuration....
</session-factory>
</hibernate-configuration>
There are few problems like following,

But these are due to case sensitivity of unix which was probably not there in case of Windows. Rest of the exception are trivial to solve. I ran following docker commands,
sudo docker run -ti --rm -p 8888:8080 -p 8009:8009 -v $(pwd):/usr/local/tomcat/webapps/ --name tomcat tomcat:9-jre8 bash
sudo docker run -d --name mysql -p 49162:3306 -p 49161:80 -p 49160:22 lxitgto/mysql-phpmyadmin:v1
and rest of the network command.
I am currently deploying a maven-built .war file to Elastic Beanstalk, using the 64-bit AmazonLinux Server for Tomcat 7. However, the application, which runs fine off of localhost, is not running due to the following error (Stack Trace at the bottom):
javax.naming.NamingException: com.mysql.jdbc.Driver
I am connecting to an external Xeround instance. After reading around on the web, I attempted to modify my app's context.xml to this:
<Resource auth="Container"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" //<- NOT THERE BEFORE
driverClassName="com.mysql.jdbc.Driver"
logAbandoned="true"
maxActive="100"
maxIdle="30"
maxWait="10000"
name="jdbc/xxxx-01292013"
password="xxxx"
removeAbandoned="true"
removeAbandonedTimeout="60"
type="javax.sql.DataSource"
url="jdbc:mysql://instancexxxx.db.xeround.com:xxxx/xxxx-01292013? autoReconnect=true"
username="xxxx-general"/>
Has anyone else had a problem uploading and using a previously working version to an Elastic Beanstalk Tomcat 7 app and found a way to get it working?
I have also read this post, but I don't know where to add in the .ebextensions file in a Netbeans maven project, and I don't understand what that would do. Thanks for any help.

Many people currently seem to be having trouble getting the .ebextensions approach to work at the moment. Here is a work-around just to get up and running. I wouldn't run in production like this, but I have used it to do test/debug when I got frustrated with .ebextensions.
You can put the mysql driver directly in your WAR. If you are using Maven, just add this to the pom.xml:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.6</version>
</dependency>
You can also add this to the META-INF/context.xml
<Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" factory="org.apache.commons.dbcp.BasicDataSourceFactory" type="javax.sql.DataSource"
url="jdbc:mysql://XXXXXXX
... />
And put this in the pom.xml (Otherwise the BasicDataSourceFactory isn't found):
<dependency>
<groupId>commons-dbcp</groupId>
<artifactId>commons-dbcp</artifactId>
<version>1.4</version>
</dependency>
<dependency>
<groupId>commons-pool</groupId>
<artifactId>commons-pool</artifactId>
<version>1.6</version>
</dependency>
<dependency>
<groupId>commons-collections</groupId>
<artifactId>commons-collections</artifactId>
<version>3.2.1</version>
</dependency>
I'm unable to deploy my web app with MySQL 5.5.11 backend to JBoss 5. I get this error:
Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver from BaseClassLoader#262b2310
I pasted my stack trace below.
Here's what I've done...
I added mysql-connector-java-5.1.14-bin.jar to {JBOSS_HOME}/lib (that connector should work with MySQL 5.5.11 right?). I also added mysql-ds.xml to {JBOSS_HOME}/server/default/deploy.
<datasources>
<local-tx-datasource>
<jndi-name>MySqlDS</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/my_libl_db</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>root</user-name>
<password>test</password>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
</local-tx-datasource>
</datasources>
Also, I made sure the mysql-connector-java-5.1.14-bin.jar in my lib folder is in my web apps classpath. In the JBoss Admin Console, under Resources/Datasources, I do see MySqlDS with a status of up.
My project (in Eclipse Indego Release) is an Enterprise Application Project with 1 Dynamic Web Project. The web app has has an #Entity bean and a #Stateless bean. The #Stateless is being injected to a servlet (using #EJB). Here's my persistence.xml:
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0">
<persistence-unit name="ContactBookPersistUnit" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:/MySqlDS</jta-data-source>
<class>com.contact.model.Contact</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
</properties>
</persistence-unit>
</persistence>
What could I be doing wrong?

This bit of documentation says you need to add the JAR to the /lib file in your default server configuration:
http://docs.jboss.org/jbossas/getting_started/v4/html/db.html
UPDATE: JBOSS 6 and newer has been rewritten to be more modular. You have to add JBDC drivers to your /module directory.
