问题描述
我试图将Spring AOP用于记录目的.我已经设置了日志记录捆绑包和其中的OSGi服务.
I am trying to use the Spring AOP for logging purposes. I have set up the logging bundle, and the OSGi service in it.
我还有另一个OSGi捆绑包，它使用日志记录捆绑包中的服务作为OSGi引用.
I have other OSGi bundle which uses the service from logging bundle as a OSGi reference.
该日志包已部署到Apache Karaf中并正在运行.我无法部署其他捆绑软件.
The logging bundle is deployed into Apache Karaf and running. I can not get my other bundle deployed.
我的捆绑包中的弹簧配置是这样的:
The spring configuration in my bundle is like that:
<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>
当我尝试启动我的捆绑包时，它会给我:
When I am trying to start my bundle it gives me:

我已经将maven依赖项添加到了pom.xml中:
I have added the maven dependency into my pom.xml:
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.6.2</version>
</dependency>
仍然无法解决问题.我在这里想念什么?
Still does not solves the problem. What I am missing here?
推荐答案
问题是您要导入的Maven依赖项没有正确的OSGI清单.清单中缺少所有其他OSGI标签旁边的Export-Package标签.
The problem is that the Maven dependency you are importing does not have a proper OSGI manifest. The Export-Package tag, next to all other OSGI tags, is missing from the manifest.
因此，不会导出org.aspectj.weaver.reflect包，并且在OSGI中，这意味着该包中的类对于其他捆绑包而言是未知的.因此是ClassNotFoundException.
So, the org.aspectj.weaver.reflect package is not exported, and in OSGI this means the classes in that package will not be known to other bundles.Hence the ClassNotFoundException.
要解决您的问题，请将您的依赖项替换为以下内容:
To solve your problem, replace your dependency with the following:
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>com.springsource.org.aspectj.weaver</artifactId>
<version>1.6.2.RELEASE</version>
</dependency>
springsource jars基本上是官方版本的重新包装，但带有适当的osgi清单.
The springsource jars are basically repackages of the official versions, but with a proper osgi manifest.
