没有可用于OSGi应用程序的'javax.persistence.EntityManagerFactory'类型的合格Bean

Question

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

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;

    ...
}

persistence.xml和orm.xml文件都已放置在src/main/resource/META-INF目录中。 persistence.xml文件的内容如下：

同样， orm.xml文件的内容如下：

    ...

            <delimited-identifiers/>
        </persistence-unit-defaults>
    </persistence-unit-metadata>
</entity-mappings>

pom.xml文件中包含的与JPA相关的依赖关系和Maven软件包配置（ maven-bundle-plugin内容）如下：

Spring bean XML（包含在src/main/resource/META-INF/spring/ ）的定义如下：

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>

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？

感谢您的帮助。

在旁边

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>

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。

Answer 1

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" 。

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。

Answer 2

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

Answer 3

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);

这并不能解决问题本身，而是可以彻底消除解决问题。 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。
