You explicitly set a spring-hibernate3 dependency:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-hibernate3</artifactId>
<version>2.0.8</version>
It's not a coincidence that this is the bean you're getting the exception on.
You shouldn't need to do that; is there a reason you're not using spring-orm of the same version of Spring you're using? I haven't set an explicit hibernate3 dependency for quite some time.


An IncompatibleClassChangeError means that JVM is getting contradictory information about some class. This typically happens when you compile some code against one version of an class or interface, but then use a different version of that class / interface at runtime. The problem is picked up at runtime when the JVM checks that the class and method signatures match.
In this case, the "Implementing class" message seems to be saying that the class that changed no longer implements some interface that it did originally. (Maybe the package name changed.)
Somewhere in your log files there should be a message that names the classes that are causing the problem, but the expurgated versions of the stacktrace that you provided don't.
I'd say they are two possibilities. One is that you've got a problem with the way you are doing your builds, and that you are not recompiling things that ought to be recompiled. The other possibility is that you've got an inconsistent mix of JARs in your WAR file; e.g. you are somehow mixing JARs from different versions of Spring.

Spring-hibernate : How to solve HibernateException" DefaultSchemaNameResolver requires Dialect to provide MySQL5Dialect"

I am newbie to Spring & Hibernate,
Trying to run project that run them togethet.
After a lot of error fixing the things work well,
But when I'm running the main class I still get that exception :

The full log of the running is long , so what I need to copy here ?

There are several things flawed in your approach
Mixing 3 different Spring versions (5.0, 4.2 and 4.0)
Using a hibernate version that isn't supported by Spring 4
Use Hibernate 4 support classes to configure hibernate 5
Tried to use Spring Boot, stepped back and worked around it
Use Hibernate instead of JPA and Hibernate as the JPA provider
First of all clean up your pom.xml and use Spring Boots dependency management to your advantage.

Notice that most of your dependencies are gone as most of them are already managed by one of the starters you had (slf4j, logback, Spring dependencies). You want to use Hibernate (and I suggest to use JPA instead of plain hibernate) it is enough to add spring-boot-starter-data-jpa to get all the needed dependencies.
Next create an application.properties in src/main/resources and put the following in there (deducted from your question).
spring.datasource.url=jdbc:mysql://localhost:3306/hibernate_mysql7?useSSL=false
spring.datasource.username=XXXX
spring.datasource.password=XXXX
spring.jpa.hibernate.ddl-auto=update
This will configure the datasource and create the schema (although you are better not to use that in production!).
Now modify your SpringHibernateMain and put an #SpringBootApplication annotation on it and change your main method. Also place your entities in a proper sub package.
#SpringBootApplication
public class SpringHibernateMain {
public static void main(String[] args) {
ApplicationContext context = SpringApplication.run(SpringHibernateMain.class ,args);
ManageEmployee manager = context.getBean(ManageEmployee.class);
/* Add few employee records in database */
Integer empID1 = manager.addEmployee("Spring222", "TODAY222", 30000);
Integer empID2 = manager.addEmployee("Avraham-spring", "Das", 5000);
Integer empID3 = manager.addEmployee("Sarah wigh spring", "Paul", 10000);
/* List down all the employees */
manager.listEmployees();
/* Update employee's records */
manager.updateEmployee(empID1, 5000);
System.out.println(empID2 + " = empID2");
/* Delete an employee from the database */
manager.deleteEmployee(empID2);
/* List down new list of the employees */
manager.listEmployees();
InsertRecords2 producer = context.getBean(InsertRecords2.class);
producer.updateProducts();//it's running insertion from inside
System.out.println("check if done");
}
}
Now place the SpringHibernateMain in a decent package like springboot.beans.app (as you had) and place the entities in springboot.beans.app.entities and everything else in springboot.beans.app.services (instead of what you have now).
The thing left for you is to "rewrite" your classes InsertRecords2 and ManageEmployee to use the EntityManager instead of the plain SessionFactory. It will still use Hibernate underneath but generally it is better to use JPA and only plain Hibernate in those cases you really need.

Using #Transactional annotation for hibernate application resulting in error

I am trying to integrate spring with hibernate this morning. I want to use spring transaction manager. But getting the below error. The error has something to do with #Trasactional Annotation. If i remove the annotation,im able to get the bean from the spring container.
Exception in thread "main" java.lang.ClassCastException: com.sun.proxy.$Proxy19 cannot be cast to com.hibernate.dao.EvntDAOImpl
at com.hibernate.action.HibernateAction.main(HibernateAction.java:17)

Thanks in advance...

The problem is in the place where you are injecting EventDaoImpl.
Just replace
#Autowired EventDaoImpl eventDaoImpl
with
#Autowired EventDao eventDao
wherever you need Spring to autowire the dao.
Or if you are getting the bean from the applicationContext use:
EvntDAO evntDAO = (EvntDAO) context.getBean("evntDAO");
The problem is caused by the fact that the use of #Transactional annotation on the dao's implementation code means that Spring will create a JDK dynamic proxy for it, which cannot be cast to the implementation class. Here is the complete documentation of Spring's AOP capabilities (where the creation of JDK dynamic proxies and CGLib class proxies is fully explained).
What that essentially means is that because of #Transactional, when you call context.getBean("evntDAO") you don't get back your EventDaoImpl (as one would expect), but you actually get back an object whose class is java.lang.reflect.Proxy which has been created by Spring. That proxy object implements EventDao (and therefor can be cast to it) but it's signature has nothing to do with EventDaoImpl (and hence the ClassCastException since it does not extend EventDaoImpl). When a method is called on the proxy various things happen before and/or after the call is actually delegated to EventDaoImpl (what happens before/and or after the actual call to EventDaoImpl is controlled by Spring though the implementation of InvocationHandler).

RoleRepository is
import org.springframework.data.jpa.repository.JpaRepository;
import org.wahid.cse.entity.Role;
public interface RoleRepository extends JpaRepository<Role, Integer>{
}

Spring Data JPA by default looks for an EntityManagerFactory named entityManagerFactory. Check out this part of the Javadoc of EnableJpaRepositories or Table 2.1 of the Spring Data JPA documentation.
That means that you either have to rename your emf bean to entityManagerFactory or change your Spring configuration to:
<jpa:repositories base-package="your.package" entity-manager-factory-ref="emf" />
(if you are using XML)
or
#EnableJpaRepositories(basePackages="your.package", entityManagerFactoryRef="emf")
(if you are using Java Config)

Had this issue when migrated spring boot 1.5.2 to 2.0.4.
Instead of creating bean I've used #EnableAutoConfiguration in the main class and it solved my problem.

In your application context, change the bean with id from emf to entityManagerFactory:
<bean id="emf"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="packagesToScan" value="org.wahid.cse.entity" />
<property name="dataSource" ref="dataSource" />
<property name="jpaProperties">
<props>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
</props>
</property>
<property name="persistenceProvider">
<bean class="org.hibernate.jpa.HibernatePersistenceProvider"></bean>
</property>
</bean>
To
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="packagesToScan" value="org.wahid.cse.entity" />
<property name="dataSource" ref="dataSource" />
<property name="jpaProperties">
<props>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
</props>
</property>
<property name="persistenceProvider">
<bean class="org.hibernate.jpa.HibernatePersistenceProvider"></bean>
</property>
</bean>

I had this issue after migrating from spring-boot-starter-data-jpa ver. 1.5.7 to 2.0.2 (from old hibernate to hibernate 5.2). In my #Configuration class I injected entityManagerFactory and transactionManager.
//I've got my data source defined in application.yml config file,
//so there is no need to configure it from java.
#Autowired
DataSource dataSource;
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
//JpaVendorAdapteradapter can be autowired as well if it's configured in application properties.
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(false);
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(vendorAdapter);
//Add package to scan for entities.
factory.setPackagesToScan("com.company.domain");
factory.setDataSource(dataSource);
return factory;
}
#Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory);
return txManager;
}
Also remember to add hibernate-entitymanager dependency to pom.xml otherwise EntityManagerFactory won't be found on classpath:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>5.0.12.Final</version>
</dependency>

I think this is related to the newer version of spring boot plus using spring data JPA.
Just replace the #Bean annotation for public LocalContainerEntityManagerFactoryBean entityManagerFactory()
to
#Bean(name="entityManagerFactory")
Determining the name of bean should solve the issue.

It might help somebody.
For me none of the above solutions worked so I went into the folder where my project is situated deleted .idea folder, imported my project again and run - mvn clean install.
After this everything worked fine.
I am using IntellJ.

In my specific case I seemed to have been missing the dependency
<!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>5.1.3.RELEASE</version>
</dependency>

just updated the springboot version to 2.1.3 and it worked of me

I had the same problem and got it resolved by deleting .m2 maven repo (C:\Users\user\ .m2)

It seems that this file is clear. But what is the main problem that JDBC driver cannot be loaded while I am trying to create a dataSource bean.

Anyone?
Thanks in advance

Get rid of the ; at the end of your property
jdbc.driverClassName=com.mysql.jdbc.Driver;
Spring uses reflection and the value of that property to load a Class instance by fully qualified class name. There is no class called com.mysql.jdbc.Driver;. There is a class called com.mysql.jdbc.Driver, so use that.
jdbc.driverClassName=com.mysql.jdbc.Driver

did you add the postgres dependency in your pom.xml ??
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.3-1100-jdbc41</version>
</dependency>

spring-orm 3.2 require different JtaPlatform package, instead of hibernate-core 4.3

I have dependency to spring-orm 3.2 and hibernate-core 4.3.
My spring hibernate config:
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="packagesToScan" value="my.domain.package"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
</props>
</property>
</bean>
In runtime i have exception
Caused by: java.lang.ClassNotFoundException:
org.hibernate.service.jta.platform.spi.JtaPlatform
in SpringSessionContext class. In my libs i see JtaPlatform in another hibernate package:
org.hibernate.engine.transaction.jta.platform.spi.JtaPlatform
(engine.transaction instead of service in package)
what am I doing wrong?
do not reproduced in 4.2.8 (JPA 2.0 instead of JPA 2.1), but I don't understand, why they broke comparability in minor release

Try changing the version of hibernate-core artifact you are using. JtaPlatform had been moved to another package since 4.3.0.Beta1. Try using 4.2.8.Final, it contains JtaPlatform in appropriate package.

Since Hibernate 4.3.x, the JtaPlatform class is refactored to a new package. To fix it,you need to upgrade your spring version to 4.1.x latest release.Below I am providing the code for pom.xml which I have tested for my own application.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.3.7.Final</version>
