Spring Hibernate transaction committing but not saving in DB - spring

Question

Using Spring Boot, declarative transaction management.
Find operation is working fine but save is not reflecting changes in DB.
Please let me know if any more information is required.
this.getCurrentSession().saveOrUpdate(entity);
Spring Boot configuration:
#SpringBootApplication(exclude = {ErrorMvcAutoConfiguration.class,
DataSourceAutoConfiguration.class,
DataSourceTransactionManagerAutoConfiguration.class,
HibernateJpaAutoConfiguration.class,
JdbcTemplateAutoConfiguration.class,
TransactionAutoConfiguration.class,
WebSocketAutoConfiguration.class})

Service method:
#Override
public void test() {
TestResource testResource = testResourceDao.findById(1l).get();
testResource.setPosition(7);
testResource.save(testResource); //this calls this.getCurrentSession().saveOrUpdate(entity);
//testResource.flushSession();
}
