问题
Noramlly all the default configurations of Spring-boot are totally fine. But now I need to deploy my application to a Weblogic 12.2 Server and I am facing some issues regarding persistence.
I just wondering how to set the JPA EntityManagerFactory for persistence unit NOT to 'default'. Because by startup of the application I can see those logs:
2017-05-23 08:16:34.608 INFO 30827 - j.LocalContainerEntityManagerFactoryBean []: Building JPA container EntityManagerFactory for persistence unit 'default'

2017-05-23 08:16:48.205 INFO 30827 - j.LocalContainerEntityManagerFactoryBean []: Initialized JPA EntityManagerFactory for persistence unit 'default'
2017-05-23 08:16:55.348 INFO 30827 - o.h.h.i.QueryTranslatorFactoryInitiator []: HHH000397: Using ASTQueryTranslatorFactory
So I am not sure if weblogic is using the default persistence unit (eclipselink) or really hibernate. So I was thinking to set the persistence unit explicity anywhere in my spring-boot application.
Is there any way to set hibernate as default unit explicit?
EDIT:
I was asking this before because I get an exception by runtime. The org.eclipse.persistence libraries are used for unmarshalling xml.

Sure I see there is a conversion issue, but on tomcat its running and I dont use any eclipse libraries. So means any library of weblogic is overriding mine.
The exception occours at this line:
javax.ws.rs.core.Response bookResponse = response.readEntity(BookResponse.class);
Any idea to get the app running again?

Yes you can do it when you configure, but you need to configure your datasource, transactionManager and Entitymanager yourself. Something like this will do
@Configuration
@EnableJpaRepositories(
entityManagerFactoryRef = "notDefaultEntityManagerFactory",
transactionManagerRef = "notDefaultTransactionManager",
basePackageClasses = notDefaultRepository.class)
public class SomesqlDb{
@Bean
public DataSource dataSourcenotDefault() {
return getDataSource(poolSize, driverClassName, jdbcUrl, userName, password);
}
@Bean(name = "notDefaultTransactionManager")
PlatformTransactionManager notDefaultTransactionManager(EntityManagerFactory notDefaultEntityManagerFactory) {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(notDefaultEntityManagerFactory);
return txManager;
}
@Bean(name = "notDefaultEntityManagerFactory")
LocalContainerEntityManagerFactoryBean notDefaultEntityManagerFactory() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSourcenotDefault());
em.setPackagesToScan(notDefaultRepository.class.getPackage().getName(), notDefaultBi.class.getPackage().getName());
em.setPersistenceUnitName("notDefaultDb");
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(false);
em.setJpaVendorAdapter(vendorAdapter);
return em;
}
}
In this case persistance unit is named as notDefaultDb. This is done by this line em.setPersistenceUnitName("notDefaultDb")
EDIT : Based on inputs from @M.Denium, this can be done even simpler if you name your entity manager factory as entityManagerFactory(default) . So that all the Auto configuration works out of the box and you would end up configuring only entity manager factory.
@Bean
LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSourcenotDefault());
em.setPackagesToScan(notDefaultRepository.class.getPackage().getName(), notDefaultBi.class.getPackage().getName());
em.setPersistenceUnitName("notDefaultDb");
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(false);
em.setJpaVendorAdapter(vendorAdapter);
return em;
}

Thanks @M. Deinum / @pvpkiran.
In case it helps someone, the following works for me on WebSphere ND 8.5.5.15:
@Configuration
public class JPAConfiguration {
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource());
em.setPackagesToScan(new String[] { "com.example.model" });
em.setPersistenceUnitName("org.hibernate.jpa.HibernatePersistenceProvider");
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(false);
em.setJpaVendorAdapter(vendorAdapter);
return em;
}
@Bean
public DataSource dataSource(){
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("oracle.jdbc.OracleDriver");
dataSource.setUrl("jdbc:oracle:thin:@xx.xx.xx.xx:xxxx:db");
dataSource.setUsername( "username" );
dataSource.setPassword( "password" );
return dataSource;
}
}
I am using Spring boot 2.1.8.RELEASE.
