Hi,
I am developing my first AspectJ example, and I want to call an Aspect
method before and after executing a method in another class. Let me give
an example. I have in [1] the main class that invokes the |teste1()|
method. I want to invoke the methods |setup()| and |cleanup()| in [2]
when invoking |teste1()|. In [3], I have my |spring.xml|.
This is example is not working, and I don’t understand why? Any help to
explain what am I doing wrong?
Thanks,
[1] My main class.
|package org.psc.spring; public class MyMain { public void teste1() { int
a = 1; System.out.println("Var. a: " + a); } public static void
main(String[] args) { MyMain main = new MyMain(); main.teste1(); } } |
[2] My AspectJ
|package org.psc.spring; public class MyMain { public void teste1() { int
a = 1; System.out.println("Var. a: " + a); } public static void
main(String[] args) { MyMain main = new MyMain(); main.teste1(); } } |
[3] My spring.xml
