OSGi Spring Data JPA 不起作用

Question

我想将Spring Data使用到我的osgi karaf捆绑包中。所以我需要将 jpa 存储库注册为 osgi 服务并将其用于另一个捆绑包。

这是我的配置，

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:jpa="http://www.springframework.org/schema/data/jpa"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:osgi="http://www.springframework.org/schema/osgi"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.1.xsd
        http://www.springframework.org/schema/data/jpa
        http://www.springframework.org/schema/data/jpa/spring-jpa-1.2.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
        http://www.springframework.org/schema/osgi
        http://www.springframework.org/schema/osgi/spring-osgi-1.2.xsd">

    <context:annotation-config/>

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <constructor-arg ref="entityManagerFactory"/>
    </bean>
    <osgi:reference id="entityManagerFactory" interface="javax.persistence.EntityManagerFactory"/>
    <tx:annotation-driven/>
    <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect"/>
    <jpa:repositories base-package="org.redhat.support.repository"/>
      <osgi:service interface="org.redhat.support.repository.TestingRepository" ref="testingRepository"/>
</beans>

保险丝异常消息是，

如何解决这个问题？任何建议。提前谢谢。

此错误告诉您没有安装提供 Spring 数据 jpa 命名空间的捆绑包。您是否安装了 Spring 数据包？

即使您正确安装了所有内容，我也不确定 spring 数据是否在 OSGi 中有效。春天很久以前就放弃了OSGi。所以我会尽量避免在OSGi中使用任何弹簧技术。
