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

How can i resolve it?

Answer 1

It was resolved when i've updated aspectj version from 1.6.12 to 1.8

Answer 2

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.

Answer 3

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.
