There is a thread in Stackoverflow where this issue is discussed:
To summarise, this is the configuration to implemented that worked.
Set manual configuration for JPA
@Bean 
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

return sessionFactory;
}

JPA by default searches sessionFactory by name 'entityManagerFactory' so change the code to:
@Bean(name="entityManagerFactory")
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

return sessionFactory;
}
