使用Spring AOP的在OSGi包(Use Spring AOP in OSGi bundle)

我试图使用Spring AOP进行日志记录。我已经设置了记录包和OSGi IT服务。

我有其他OSGi其使用从记录包作为服务捆绑OSGi参考。

日志记录包被部署到Apache Karaf和运行。我不能让我的另一束部署。

在我的包Spring的配置是这样的：

<osgi:reference id="loggingIterceptor" interface="com.groupgti.commons.log.LoggingInterceptorAdvice"/>
<aop:config>
    <aop:pointcut id="logger" expression="@annotation(com.groupgti.esb.assessments.kenexa.log.InOutLogger)"/>
    <aop:advisor pointcut-ref="logger" advice-ref="loggingIterceptor"/>
</aop:config>

当我想开始我的管束它给了我：

我已经添加了Maven的依赖关系到我pom.xml ：

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.6.2</version>
</dependency>

仍然没有解决问题。我是缺少在这里？

问题是，要导入的Maven的依赖没有一个正确的OSGI清单。以出口包装标签，旁边都是其他OSGI的标签，从清单中失踪。

因此，org.aspectj.weaver.reflect包没有出口，在OSGI这意味着在该包中的类将不知道其它束。因此，ClassNotFoundException的。

为了解决你的问题，请用以下的依赖：

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>com.springsource.org.aspectj.weaver</artifactId>
    <version>1.6.2.RELEASE</version>
</dependency>

SpringSource的罐子基本上是重新包装的官方版本，而是一个适当的OSGi清单。
