While migrating my project to springboot 3.1.0 with hibernate 6.2.2 and mysql-connector-j 8.0.33 , I am getting an error :Unable to resolve name [org.hibernate.dialect.MySQLInnoDBDialect] as strategy [org.hibernate.dialect.Dialect]

Hibernate dialect used is org.hibernate.dialect.MySQL8Dialect

public LocalContainerEntityManagerFactoryBean entityManagerFactory() {  
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();  
factory.setJpaVendorAdapter(vendorAdapter);  
factory.setPackagesToScan(“com.project.entites”);  
Properties jpaProperties = new Properties();  
jpaProperties.setProperty(“hibernate.hbm2ddl.auto”, “none”);  
jpaProperties.setProperty(“hibernate.show\_sql”, “true”);  
jpaProperties.setProperty(“hibernate.dialect”, “org.hibernate.dialect.MySQL8Dialect”);  
factory.setJpaProperties(jpaProperties);  
return factory;  
}

Since Hibernate 6, version-specific dialects were deprecated in favour of automatic database version discovery. You should just use the standard `org.hibernate.dialect.MySQLDialect` dialect.

See also the Hibernate 6 [migration guide chapter about dialects](https://docs.jboss.org/hibernate/orm/6.0/migration-guide/migration-guide.html#_dialects).

That’s weird, looks like a class loading issue on your side. I can confirm that the class name and package you’re trying to use are correct.
