I got ClassNotFoundException when i tried to switch spring to use load time weaving

Question

I've added a <context:load-time-weaver/> in my application context. And i've added necessary libraries and javaagent to my pom.xml

Then i got following error

2014-05-23T17:48:11.549+0600  SEVERE  Unable to find class 'com.myproject.dao.impl.BlobDataDaoTest$' in repository

    at org.aspectj.weaver.World.resolveToReferenceType(World.java:485)
    at org.aspectj.weaver.World.resolve(World.java:326)

How can i resolve it?

Obviously the weaver cannot find at least some of your application classes. This must be a class-loading issue. Maybe your aop.xml is not in the right location or configured in a wrong way - hard to tell with so little information.

What additional information can i tell you? It's appear also when i run test. I haven't created a aop.xml file. Is it necessary? – kraken May 23 '14 at 14:58
Sure. If you want to use load-time weaving, you need to configure it. I recommend you to RTFM, e.g. http://docs.spring.io/spring/docs/3.0.0.M4/reference/html/ch07s08.html. – kriegaex May 23 '14 at 16:20

There are external dependencies in my tests. They imported because in my tests i mock its. This Unable to find class errors all about this external classes.
