具有aspectj注释的Spring AOP

Question

I am sorry that my question is little bit silly, but i need to understand, i am trying to write a logger based on spring aop, i know that there are several realizations, like xml based schema or aspectj annotations, in case i prefer an aspectj annotations does it means that i dont need a xml configuration file at all? I have read many tutorials and examples ones were with xml while another ones were not, now i have messed up with it, can some one give a good explanation for a newbie or mare a ref? Thank you.

If you're referring to using AspectJ annotations with Spring AOP then you will need a bit of XML configuration on the Spring side but can mostly manage the aspects with annotations. The XML configuration you will need is to at least:

1. Turn on AOP auto-proxy with <aop:aspectj-autoproxy/>
2. Use Spring component scan to find your annotated aspects with <context:component-scan base-package="package.of.some.aspect" />

An example can be found here

You should note there are several limitations with how AspectJ annotations apply with respect to Spring AOP, which can be found in the Spring documentation
