I am familiar with Spring AOP, although not having much hands on experience on that.
My question is, if I want to have some AOP functionality for some methods of a class, not all, then can it be possible with single pointcut. Say, I have four methods save1,save2,get1 and get2 in my class and I want to apply AOP on save1 and save2 only, then in that case how can I create a single pointcut for that? How will my pointcut expression looks like? OR Is it even possible?
There are many ways to do it(with wildcard expression, with aspectJ annotation, ..) i will give an example with aspectJ
class MyClass{ @MyPoint public void save1(){ } @MyPoint public void save2(){ } public void save3(){ } public void save4(){ } } @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.METHOD) public @interface MyPoint { } @Aspect @Component public class MyAspect { @Before("@annotation(com.xyz.MyPoint)") public void before(JoinPoint joinPoint) throws Throwable { //do here what u want } } So you are all set, as long as you marked @Mypoint annotation, spring will call before aspect for this method, make sure spring is managing this method and object, not you. include aspectJ in your classpath
You need to specify a pointcut expression to select the methods with to apply your advice.
See 7.2.3 Declaring a pointcut in the Spring Documentation and use the execution joinpoint designator to select the methods.
You can use or and and with pointcut expressions:
execution(* my.Class.myMethod(..)) or execution(* my.Class.myOtherMethod(..))
