How to fix my Spring Dependencies in pom.xml

问题

My code compiles, but when I try to execute it, I get the following error:

Any help would be greatly appreciated as I'm trying to get past this issue to test my code.

回答1:

After some research I found that versions of the asm jar file appear in both the 'Spring 2.5 AOP' bundle, and the 'Hibernate 3.2 core' bundle.

By deleting the asm jar file from the Spring 2.5 AOP bundle the web app now starts and works fine.
