How to share Entity classes across multiple Persistence Unit?
I have 2 MySql databases (dbOne, dbTWO) with the same table "users"
I would like to have an Entity class like this :
#Entity
public class User {
...
...
}
shared between the 2 PU (of dbONE and dbTWO).. (eclipse.persistence)
i tried with :
<persistence-unit name="one_PU" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>com.model.User</class>
<validation-mode>NONE</validation-mode>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<shared-cache-mode>NONE</shared-cache-mode>
<properties>
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost/dbONE"/>
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
<property name="javax.persistence.jdbc.user" value="*****"/>
<property name="javax.persistence.jdbc.password" value="******"/>
<property name="eclipselink.jdbc.batch-writing" value="JDBC"/>
<property name="eclipselink.jdbc.batch-writing.size" value="1000"/>
<property name="eclipselink.jdbc.cache-statements" value="false"/>
<property name="eclipselink.cache.shared.default" value="false"/>
</properties>
</persistence-unit>
<persistence-unit name="two_PU" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>com.model.User</class>
<validation-mode>NONE</validation-mode>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<shared-cache-mode>NONE</shared-cache-mode>
<properties>
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost/dbTWO"/>
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
<property name="javax.persistence.jdbc.user" value="*****"/>
<property name="javax.persistence.jdbc.password" value="*****"/>
<property name="eclipselink.jdbc.batch-writing" value="JDBC"/>
<property name="eclipselink.jdbc.batch-writing.size" value="1000"/>
<property name="eclipselink.jdbc.cache-statements" value="false"/>
<property name="eclipselink.cache.shared.default" value="false"/>
</properties>
</persistence-unit>
without success..
Is it possible?..how can i do that?
I'm trying to test spring batch using dbunit but when batch runs HibernateCursorItemReader it doesn't see temporary created objects in the db. But if I create entities using HibernateDaoSupport everything is fine and I can work with test data. Does anybody know how to force batch see my test entities?
My test classes:
#RunWith(SpringEasyMockRunner.class)
#TestExecutionListeners({DependencyInjectionTestExecutionListener.class, TransactionalTestExecutionListener.class, DbUnitTestExecutionListener.class})
#Transactional
#ContextConfiguration({"classpath:/integration-test-context.xml"})
#DbUnitConfiguration(
databaseConnection = {"dbUnitDatabaseConnection"}
)
public abstract class BaseIT implements ApplicationContextAware {
...
}
#RunWith(SpringEasyMockRunner.class)
#ContextConfiguration("classpath:/sopl-test-context.xml")
#DatabaseSetup(value = "classpath:data/SoplTestDataIT.xml", type = DatabaseOperation.CLEAN_INSERT)
#Slf4j
public class SoplOrderTestIT extends BaseIT {
...
}
And configs integration-test-context.xml:

query:
em.createQuery(query).setHint("javax.persistence.query.timeout", 1)
.setFirstResult(payload.getStart())
.setMaxResults(payload.getSize() > MAX_FETCH ? MAX_FETCH : payload.getSize())
.getResultList()
The query returned 7 thousand rows... but the timeout does not work.
The JDBC Postgresql driver does not work with the property javax.persistence.query.timeout,
so i did an workaround.
em.unwrap(Session.class).doWork(connection -> {
long maxTimeOutMil = TimeUnit.SECONDS.toMillis(MAX_TIMEOUT);
connection.createStatement().execute("set statement_timeout = " + maxTimeOutMil);
});
This is my situation:
a Postgres database where I have only Spring Batch tables
an Oracle database where I have business data to read, write and update
I have tried to configure an XA enviroment with Atomikos and it seems to work but honestly I haven't understand what is exactly happening.
Can you check my configuration, please? I'm totally noob in these things...
If I set "hibernate.transaction.jta.platform" to "com.atomikos.icatch.jta.hibernate4.AtomikosPlatform" instead of my class "SpringJtaPlatformAdapter" it seems that the batch doesn't commit on my Postgres DB. Why?
For testing I was using Spring "JpaPagingItemReader". With this reader I get always the exception "java.lang.IllegalStateException: A JTA EntityManager cannot use getTransaction()" so I copied this solution: solution
Why I need to do this? Is there another JpaReader for XA?
Thanks a lot for your help.
Here my configuration:
spring-batch-core 3.0.7.RELEASE
spring-jdbc and spring-orm 4.0.5.RELEASE
hibernate-entitymanager 5.0.7.Final
Atomikos transactions-jta, transactions-jdbc, transactions-hibernate4 4.0.6
