没有可用于OSGi应用程序的'javax.persistence.EntityManagerFactory'类型的合格Bean
[英]No qualifying bean of type 'javax.persistence.EntityManagerFactory' available for OSGi Application
问题描述
I am working on a Maven OSGi bundle that incorporates JPA (through EclipseLink ) and when I deploy the bundle into the OSGi container (Virgo), I receive the following error: 
我正在使用（通过EclipseLink ）合并了JPA的Maven OSGi捆绑软件，并且将捆绑软件部署到OSGi容器（处女座）时，收到以下错误：
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.persistence.EntityManagerFactory' available
The class in question that causes the error is: 引起错误的相关类为：
@Configurable
@Entity
@Table(name = "SCHEDULE")
@RooJavaBean
@RooToString
@RooJpaActiveRecord(versionField = "", table = "SCHEDULE")
@RooDbManaged(automaticallyDelete = true)
public class Schedule {
@PersistenceContext
transient EntityManager entityManager;
...
}
Both the persistence.xml and orm.xml files have been placed in the src/main/resource/META-INF directory. persistence.xml和orm.xml文件都已放置在src/main/resource/META-INF目录中。 The contents of the persistence.xml file is as follows: persistence.xml文件的内容如下：

Lastly, there is a database.properties file in src/main/resource/META-INF/spring/ that contains the following: 最后，在src/main/resource/META-INF/spring/中有一个database.properties文件，其中包含以下内容：
database.driverClassName=com.mysql.jdbc.Driver
database.url=jdbc\:mysql\://localhost\:3306/<hidden>
database.username=<hidden>
database.password=<hidden>
Am I making a configuration or wiring mistake somewhere that is causing the EntityManagerFactory not to be created or wired correctly upon deployment? 我是否在某个地方配置或接线错误导致EntityManagerFactory在部署时无法正确创建或接线？
Thank you for the help. 感谢您的帮助。
Aside 在旁边
I have also attempted to follow A Guide to Hibernate with Spring 4 and include the following in the definition of org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean : 我还尝试遵循Spring 4的《休眠指南》，并在org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean的定义中包括以下内容：
<bean id="myEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
...
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
</property>
</bean>
I follow through and added all of the OSGi bundles that go along with the HibernateJpaVendorAdapter class (eg hibernate-core, hibernate-osgi, etc.) and that led back to the same error as above. 我遵循并添加了所有与HibernateJpaVendorAdapter类一起使用的OSGi捆绑软件（例如hibernate-core，hibernate-osgi等），并导致了与上述相同的错误。

I'm hazarding a guess at this but you have two persistence units defined, name="PGSQLPersistence" and name="PGSQLTESTPersistence" . 我对此很冒险，但是您定义了两个持久性单元，分别为name="PGSQLPersistence"和name="PGSQLTESTPersistence" 。
I think you need to specify which PU you want to use in your @PersistenceContext annotation, eg @PersistenceContext(unitName = "PGSQLPersistence") although I would have expected a slightly different exception thrown as a single PU cannot be automatically determined. 我认为您需要指定要在@PersistenceContext批注中使用的PU，例如@PersistenceContext(unitName = "PGSQLPersistence")尽管我希望抛出一个略有不同的异常，因为无法自动确定单个PU。

尝试按照Kerry的建议通过名称更改@PersistenceContext上的unitName属性

The solution I found was to circumvent the JPA portion of the bundle I was creating and directly create a HibernatePersistenceProvider : 我发现的解决方案是规避我正在创建的捆绑软件的JPA部分，并直接创建HibernatePersistenceProvider ：
EntityManagerFactory factory = new HibernatePersistenceProvider().createEntityManagerFactory("persistenceUnitName", null);
This does not solve the issue itself but removes the issue of resolution entirely. 这并不能解决问题本身，而是可以彻底消除解决问题。 My suspicion is that OSGi and JPA are not being configured correctly in our environment and therefore, OSGi cannot find any EntityManagerFactory instances to inject. 我怀疑OSGi和JPA在我们的环境中配置不正确，因此OSGi找不到要注入的任何EntityManagerFactory实例。
