Migration to hibernate core 5.2.1 ava.lang.NoSuchMethodError: org.hibernate.Session.getFlushMode()Lorg/hibernate/FlushMode;

Question

Using spring version:4.3.1,Spring data:1.10.2,hibernate core: 5.2.1. using postgres Database pg connector version :9.4.1208.jre7 After upgrading from hibernate 5.1.0 to 5.2.

Answer 1

This looks odd as the method signature support for the Hibernate 5.2 API was added in Spring Framework 4.3.0.RELEASE where it specifically looks for getHibernateFlushMode first and is then followed up by getFlushMode.

I'd say chances are you likely have the new Hibernate libraries on your classpath but you may have an older version of Spring Framework in the classpath which isn't compatible.
