aop네임스페이스를 이용하여 AOP구현(Spring3.X,박태근)

 > - Spring3.X의 aop Namespace를 이용하여

-------------------------------OnjWorldImpl --------------------------------------

package onj.edu.project_Namespace;

import onj.edu.project.OnjWorld;

public class OnjWorldImpl {
public void onjHello(){
System.out.println("Onj에 오신것을 환영합니다. ----Hello1----");
}

public void onjHello1() throws Exception{
System.out.println("Onj에 오신것을 환영합니다.---- Hello2----");
//throw new Exception("Exception");
}

public void onjGoodBye(){
System.out.println("끝났어요~~~~~~");
}
 
}

----------------------------------- OnjWorldBean -----------------------------

package onj.edu.project_Namespace;


public class OnjWorldBean {

private OnjWorldImpl dependency;

public void run() throws Exception{
dependency.onjHello();
dependency.onjHello1();
dependency.onjGoodBye();
}

public void setDependency(OnjWorldImpl dependency){
this.dependency = dependency;
}
}

-------------------- OnjWorldAdvice ----------------------------------------------------
package onj.edu.project_Namespace;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;

public class OnjWorldAdvice {
      public void beforeAdvice(JoinPoint joinPoint){
System.out.println("----비포 실행----"
                                        + joinPoint.getSignature().getDeclaringTypeName()+ ","
        +  joinPoint.getSignature().getName());
}

public Object aroundAdvice(ProceedingJoinPoint joinPoint) throws Throwable{
System.out.println("----어라운드 비포 실행----"
                                          + joinPoint.getSignature().getDeclaringTypeName()+ ","
          +  joinPoint.getSignature().getName());
Object rVal = joinPoint.proceed();
                      System.out.println("----어라운드 에프터 실행----"
                                                + joinPoint.getSignature().getDeclaringTypeName()+ ","
+  joinPoint.getSignature().getName());
return rVal;
}
}

------------------------------ OnjWorldExam  -------------------------------------
package onj.edu.project_Namespace;

import org.springframework.context.support.GenericXmlApplicationContext;

public class OnjWorldExam {
public static void main(String args[]) throws Exception{
GenericXmlApplicationContext ctx = new GenericXmlApplicationContext();

ctx.refresh();

OnjWorldBean bean = (OnjWorldBean)ctx.getBean("onjWorldBean");
System.out.println("--------bean------------");
bean.run();
ctx.close();
}
}
