I am trying to use AspectJ in a simple project without using Spring, and while I have seen similar questions and my code seems to be correct, I don't understand why it's not working. I'm using Eclipse Oxygen 4.7.3 (not using AJDT tools), JDK 7, maven 3.5.2, and my code is as follows:
pom.xml

MainApp.java
package com.pkg;
public class MainApp {
public static void main(String[] args) {
// TODO Auto-generated method stub
HelloWorld a = new HelloWorld();
a.printHello();
}
}
HelloWorld.java
package com.pkg;
public class HelloWorld {
private String name;
public void setName(String name) {
this.name = name;
}
public void printHello() {
System.out.println("Print Hello...");
}
}
TestAspect.java
package com.pkg;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
@Aspect
public class TestAspect {
@Before("execution(* com.pkg.HelloWorld.printHello(..))")
public void testBefore2(){
System.out.println("Yeeha");
}
}
Running mvn clean install is successful, but the output only prints the "Print Hello..." part. Should I use a different approach? (Maybe use a .aj file instead, or try load-time-weaving) Any help appreciated.
