You are not injecting an interface so you need to use CGLIB proxies, the spring reference manual states:

Spring AOP defaults to using standard J2SE dynamic proxies for AOP proxies. This enables any interface (or set of interfaces) to be proxied.

Spring AOP can also use CGLIB proxies. This is necessary to proxy classes, rather than interfaces. CGLIB is used by default if a business object does not implement an interface. As it is good practice to program to interfaces rather than classes, business classes normally will implement one or more business interfaces.

Spring has decided to use a J2SE proxy (com.sun.proxy.$Proxy57) probably because CrudService implements an interface. To force the use of CGLIB you can tweak your XML:
