Set up LocalContainerEntityManagerFactoryBean

DatabaseConfiguration.java

@Primary
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) {
    LocalContainerEntityManagerFactoryBean emfBean = new LocalContainerEntityManagerFactoryBean();
    emfBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
    emfBean.setDataSource(dataSource);

    // Other configurations
}  

Where is this code, I have a problem when I add spring data JPA in pom.xml in WebSphere 8.5, without JPA it works correctly as in your tutorial, if you could share a demo project I would really appreciate it
