Quick Start with SpringAOP
Limitations:
Due to the popularity of the Spring framework SpringAOP is the most popular AOP framework these days.
SpringAOP has it's limitation such as:
- It works only with Spring managed beans, i.e you can use @Log annotation only on spring-managed beans.
- You can not use @Log annotation constructors and methods other than public.
- Logging of method calls in same Spring managed bean will not work unless you call that method via self reference stored in that bean.
The benefit of SpringAOP is that it unlike AspectJ works with javac compiler.

<!--We need this because Spring still uses common-logging, jcl-over-slf4j will substitute calles to common-loggin.
Make sure you excluded common-logging in every module that depends on it.

@Configuration
@ComponentScan("org.foo")
@EnableAspectJAutoProxy
public class SpringAopConfiguration {
@Bean
LogAspect createLogAspect(){
return new LogAspect();
}
}Place @Log annotation on any spring bean you have to log it's method's invocation.
