Could not execute JDBC batch update:Exception in thread "main" org.hibernate.exception.ConstraintViolationException: 2 Hibernate could not execute JDBC batch update
Whereas Hibernate manages the exceptions itself by marking them as unchecked. JDBC is database dependent i.e. one needs to write different codes for different database. Whereas Hibernate is database-independent and the same code can work for many databases with minor changes.
I dont find the problem in you app, but I can answer the second question: "How to persist data correctly?" Use Spring Transaction Template, instead of some own implementation. It binds the library to Spring transaction infrastructure. @weekens: yes, it does, The same way like SessionFactory binds you to Hibernate.
If you are able to connect to the database, run a sample query like the following: select PCSF_DOMAIN_NAME from MM_REPOSITORY. If the above query executes successfully, restart the MM service. Else, correct the errors with database and restart MM service from Administration Console.
I have a pretty typical Spring Boot based web app, Spring Boot version 2.2.4 with the following "starters": data-jpa, mail, security, web, thymeleaf. I am using PostgreSQL as my data source and Spr I have been attempting to stream query results with Spring Data JPA and Hibernate using the following piece of code (data.txt is a file with 3000 lines with a number validate: validate the schema, makes no changes to the database. update: update the schema. create: creates the schema, destroying previous data. create-drop: drop the schema when the SessionFactory is closed explicitly, typically when the application is stopped. none: does nothing with the schema, makes no changes to the database In a multi user spring hibernate web application we encounter the following exception. When checking the logging it happens at multiple places. I googled around, also checked Stackoverflow, but I can't find a solution: Pre-bound JDBC Connection found! HibernateTransactionManager does not support running within DataSourceTransactionManager if Get early access and see previews of new features. nested exception is org.hibernate.service.spi.ServiceException: Unable to create requested service [org Mqia81.
