So, I insert below code in the spring context xml.

<aop:aspectj-autoproxy /> 

so, is aspectj applied to?

plz let me know and any idea that can substitute aop for better performance!!

Answer 1

 <aop:aspectj-autoproxy/> 

Just enables @AspectJ annotation support .The AOP runtime is still pure Spring AOP . See the following from spring reference.

 @AspectJ refers to a style of declaring aspects as regular Java classes annotated with 
 Java 5 annotations. The @AspectJ style was introduced by the AspectJ project as part of 
 the AspectJ 5 release. Spring 2.0 interprets the same annotations as AspectJ 5, using a 
 library supplied by AspectJ for pointcut parsing and matching. The AOP runtime is still 
 pure Spring AOP though, and there is no dependency on the AspectJ compiler or weaver.
