10.1 @Aspect defining slices, defining cut-in positions

Importorg.aspectj.lang.annotation.*; @Aspect Public classNotifier {@Before ("Execution (static void *). *.main (string[]) ")     Public voidbefore () {System.out.println ("Application is running!"); } @After ("Execution (static void *). *.main (string[]) ")     Public voidAfter () {System.out.println ("Execute end!"); } @AfterReturning ("Execution (static void *). *.main (string[]) ")     Public voidafterreturning () {System.out.println ("Return end!"); } @AfterThrowing ("Execution (static void *). *.main (string[]) ")     Public voidafterthrowing () {System.out.println ("Exception"); }}

10.2 Defining pointcuts and reusing pointcuts using Pointcup

Importorg.aspectj.lang.annotation.*; @Aspect Public classNotifier {@Pointcut ("Execution (static void *). *.main (string[]) ")     Public voidPointcup () {} @Before ("Pointcup ()")     Public voidbefore () {System.out.println ("Application is running!"); } @After ("Pointcup ()")     Public voidAfter () {System.out.println ("Execute end!"); } @AfterReturning ("Pointcup ()")     Public voidafterreturning () {System.out.println ("Return end!"); } @AfterThrowing ("Pointcup ()")     Public voidafterthrowing () {System.out.println ("Exception"); }}
