Я пытаюсь получить пакет сохраняемости OSGi, работающий на встроенной в WebLogic инфраструктуре Felix.Согласно документации WebLogic OSGi , мой источник данных WebLogic test-ds представляется доступным в качестве службы в OSGi:
Service 59 - [weblogic.jdbc.common.internal.RemoteDataSource, javax.sql.DataSource, javax.sql.CommonDataSource, java.sql.Wrapper, weblogic.jdbc.extensions.WLDataSource, java.rmi.Remote, weblogic.jdbc.common.internal.DataSourceMetaData, weblogic.common.resourcepool.ObjectLifeCycle, weblogic.jndi.CrossPartitionAware] (pid: n/a)
from Bundle 0 - System Bundle (org.apache.felix.framework), version 5.6.0
Name: test-ds
service.bundleid: 0
service.scope: singleton
Я создал пакет персистентности com.test.persistence-bundle сследующий класс сущностей:
@Entity
public class TestEntity {
@Id
private Integer id;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
}
... и persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.2" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_2.xsd">

<class>test.model.TestEntity</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle12cDialect"/>
</properties>
</persistence-unit>
</persistence>
... и манифест:

Tool: Bnd-4.2.0.201903051501
Я такжесоздал клиентский пакет com.test.service-impl, который реализует TestService из другого пакета:
@Component(service = TestService.class)
public class TestServiceImpl implements TestService {
@PersistenceContext(unitName = "test-pu")
EntityManager em;
@Override
public void foo() {
System.out.println(em);
}
}
Экземпляр EntityManager должен быть внедрен через образец для реализации службы:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:jpa="http://aries.apache.org/xmlns/jpa/v2.0.0" xmlns:tx="http://aries.apache.org/xmlns/transactions/v2.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 https://osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
<jpa:enable />
<tx:enable />
<bean id="testService" class="test.service.impl.TestServiceImpl"/>
<service ref="testService" interface="test.service.TestService"/>
</blueprint>
Однако em всегда равно нулю.Похоже, что службы EntityManager никогда не запускаются, хотя все пакеты активны.При обновлении com.test.service-impl появляется следующее сообщение:
13:20:36.380 [Blueprint Extender: 1] INFO org.apache.aries.blueprint.container.BlueprintContainerImpl - Blueprint bundle com.test.service-impl/1.0.0.SNAPSHOT is waiting for dependencies [(&(osgi.unit.name=test-pu)(objectClass=javax.persistence.EntityManager))]

Я использую Aries JPA, чтобы связать все вместе с Hibernate в качестве поставщика сохраняемости.У меня также есть Aries Blueprint и Aries Transaction со всеми необходимыми зависимостями.
