我需要哪个jar使用Spring AOP AspectJ Annotation？

Question

I'm new to Spring. I am trying to use Spring AOP annotation like the following code.

@Aspect
public class A {
    @Pointcut("execution(* Operation.*(..))")
    public void b(){} 

    @Before("b()") 
    public void c(JoinPoint jp)
    {
        System.out.println("a");
    }
}

In my referenced libraries, I put all the spring jar (aop, core, aspects , beans, context, instrument, jdbc,jms,web, webmvc, etc)

I found another jar aspectj-1.9.3.jar and added it to my libraries in my eclipse . However, I can't import org.aspectj.lang.* (which I need). My Eclipse doesn't seem to locate it.

Did I find the right jar? (so the problem is something else?) Or do I need another jar? I am trying to do it without using Maven .

Answer 1

org.aspectj.lang.joinpoint is part of the aspectj tool library. 

Add this to the Maven :

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjtools</artifactId>
    <version>1.8.9</version>
</dependency>

Answer 2

Below i have mentioned the Lightweight jars as aspectjtools is too big.

compile group: 'org.springframework', name: 'spring-aop', version: '5.1.5.RELEASE'
compile group: 'aspectj', name: 'aspectjweaver', version: '1.5.4'

Size of jars:

aspectjtools 1.9.2: 13.2 MB // too big

And

 aspectjweaver 1.9.2: 2.0 MB,  // too small as compared to aspectjtools jar
 spring AOP 5.1.5: 360 KB

So, avoid using aspectjtools jar as it is too big.
