I try to generate java class from MySql 8.0.12 database by using Hibernate Tools on eclipse
Class are well generated but without annotations (like #Entity, etc...)
Here is my Hibernate Tools configuration :
I can ping database and retrieve tables :
Here is my hibernate code generation configuration :
and
I used to work with MySQL 5 and hibernate Tools 5.2 and it worked fine !
But now i would like to upgrade my database (MySql 8)
How can I solve this issue ?
it is the Hibernate version 5.3. It is a bug.
I ran into the same problem.
Change it to 5.2 and it should work.

How can I use both in same SpringBoot project? Will it not create conflict which one is going to create tables?
Liquibase is Version Control System dedicated for track, version, and deploy database schema changes.
Hibernate is an object-relational mapping (ORM) tool for the Java programming language which provides a framework for mapping an object-oriented domain model to a relational database.
Yes of course you can use both in same Spring Boot project. Check this official guide liquibase + Hibernate for Using Liquibase with Hibernate.
I've upgraded an application from grails 2 to grails 3. This also meant an upgrade from hibernate 4 to hibernate 5. As the application is deployed on premise in quite few installations, we've used external-config to avoid migrating configurations (from groovy to yaml).
In our current config, we have:
dataSource.dialect = org.hibernate.dialect.SQLServerDialect
However, this doesn't work. Changing this to SQLServer2012Dialect solves the problem, but requires manually changing this on every installation.
Are there any settings (e.g. in hibernate) that solves this issue?
We're using jtds as driver
This may be annoying and discussed before but I could not find a good reference which would help to set a direction. I have to plan a migration of TopLink 10g (Spring 2.5 ORM Native Support) to JPA. I need some guidelines (steps) to follow and plan a successful migration.
Let me brief what I have in my technology stack. Primarily, as I mentioned above, application build around Spring 2.5 and Spring 2.5 Native ORM Support of TopLink. Spring 2.5 bundled to support only up to TopLink 10g and if you simply upgrade the TopLink JAR with the latest version it would not work as latest version of TopLink has completely changed the packaging but this still can be tackled by easily find and replace the package names. The main issue is the native api of TopLink ORM in Spring 2.5 which is built around TopLink 10g.
The reason of this migration activity is we cannot upgrade Spring until we migrate data-layer to JPA.
Please share steps if you already achieved something similar in your past or if the above briefing gives you an understanding on the problem you can also drop your opinion on how should I plan this migration.
I am facing a similar migration, toplink10g and Spring 2.5. For the integration we were using as support spring-toplink.jar, but not such support for toplink 12 that actually is the current version. At the moment seems it is not a straight fordward solution but I started first using the renaming tool provided by oracle.
The renaming tool it is necesary since jpa toplink 11 g is provided by eclipselink. You will see all the packages oracle.toplink.* will be renamed by org.eclipse.persistence.*
Did you have any advice othe advices for this migration?
We have been trying to implement a hibernate search with our project and in this case we had to implement Hibernate 3.5 previously we were using Hibernate Core 3.2.
Initially we tried to upgrade our version directly to the latest hibernate search and hibernate core. But, in Hibernate 4 they have removed the TransactionManagerLookupClass.
So, now what we can do in order to upgrade our Hibernate to Hibernate 3.5. As we can't upgrade our Application Server because we have other applications running on the same server.
Currently we are using:
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-core-4.1.9.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate-search-4.1.0.Final.jar
hibernate-search-analyzers-4.1.0.Final.jar
hibernate-search-engine-4.1.0.Final.jar
hibernate-search-orm-4.1.0.Final.jar
These are the files that we are using but, we know Hibernate 4 is not at all compatible with JBOSS 4.2.3. What we want to know that is there anyway to upgrade our hibernate core to a version where it's compatible with Hibernate search.
Secondly, the way be which we can keep the same application server.
You could use a very old version of Hibernate Search which is compatible with such a very old version of Hibernate ORM.
A better alternative would be to download a more recent version of the application server like WildFly 8 and start using that for the new applications: you can use the old JBoss 4.2 for the old applications and use a new container in parallel.
Remember that you can run multiple different application servers on the same server, you only have to make sure they use different ports.
I have been using AbstractRoutingDataSource for a while to switch between different databases. The old configuration was Spring 3 and Hibernate 3.5.5. After upgrading Hibernate to 4.2.3, AbstractRoutingDataSource has stopped working (it always retrieves the default database).
Any help would be much appreciated.
Thank you in advance
