call(Signature)切入點的語法是：
pointcut <pointcut name>(<any values to be picked up>) : call(<optional modifier> <return type> <class>.<method>(<parameter types>));
package com.eric.aspectj;
public aspect MyAspectj {
pointcut callPointCut(MyClass myClass, int age, String name) : call(void com.eric.aspectj.MyClass.foo(int, String)) && target(myClass) && args(age, name);
before(MyClass myClass, int age, String name) : callPointCut(myClass, age, name) {
System.out.println("before...name : " + name + " age : " + age);
}
after(MyClass myClass, int age, String name) returning: callPointCut(myClass, age, name) {
System.out.println("after...");
}
}
package com.eric.aspectj;
public class MyClass {
public void foo(int age, String name) {
System.out.println("foo " + name + " age is " + age);
}
public static void main(String[] args) {
MyClass object = new MyClass();
object.foo(24, "Eric Chau");
}
}
運行結果：
before...name : Eric Chau age : 24
foo Eric Chau age is 24
after...
