Question

我的项目已经有一些方面使用<aop:aspectj-autoproxy/>并使用aspectj样式@Aspect注释。但是因为我们需要建议我们控制范围之外的一些类，我们想要引入Tomcat的Spring风格加载时间编织，如http://docs.spring.io/spring/docs/3....tml#aop-aj-ltw

中所述。

我的LTW配置似乎是正确的，因为我打开了详细和调试weaver选项，我在catalina.out中看到这样的行

2013-11-28 13:17:57,167+0000 [INFO ] org.springframework.context.weaving.DefaultContext LoadTimeWeaver [main] - Using a reflective load-time weaver for class loader: org.springframework.instrument.classloading.tomcat .TomcatInstrumentableClassLoader
[TomcatInstrumentableClassLoader@53ea0105] info register aspect com.anon.profiling.aspect.MyAspect
...
[TomcatInstrumentableClassLoader@273d1402] debug not weaving 'org.quartz.SimpleTrigger'
[TomcatInstrumentableClassLoader@273d1402] debug not weaving 'org.apache.http.conn.scheme.SocketFactory'
...

我想要测试的类是在包含其他几个类的包中，我可以看到该包中的其他类被调试的方式与未编织的相同。但是大约有一半的课程（包括我感兴趣的课程......）根本没有被提及 - 要么被编织，要么被忽略或者被忽略。稍微深入研究一下我认为我发现一种模式，被忽略的类由Spring管理：要么在applicationContext.xml中声明，要么用@Inject注入另一个类。

是不是TomcatInstrumentableClassLoader不会加载spring托管bean进行编织？我需要添加到配置中以启用它吗？
