■ 파일 생성

"com.test.controller" > AOPController.java
"com.test.persistence" > AOPDAO.java(I)
					   > AOPDAOImpl.java(C)

views > "list.jsp"
	  > "add.jsp"
      > "view.jsp"
      
"com.test.aspect" > "Log.java"

 

■ servlet-context.xml -> 스캔 추가

• namespace -> aop 추가

<context:component-scan base-package="com.test.aop" />
<context:component-scan base-package="com.test.controller" />
<context:component-scan base-package="com.test.persistence" />
<context:component-scan base-package="com.test.aspect" />

 

■ 주업무 구현

• list

---------------AOPController.java------------------------
@GetMapping("/list.do")
public String list() {

    dao.list();

    return "list";
}
-----------------AOPDAO.java-----------------------------
void list();
-----------------AOPDAOImplement.java--------------------
@Override
public void list() {

    System.out.println("DOA.list");

}

• add

---------------AOPController.java------------------------
@GetMapping("/add.do")
public String add() {

    dao.add();
    System.out.println("Controller.add");

    return "add";
}
-----------------AOPDAO.java-----------------------------
void add();
-----------------AOPDAOImplement.java--------------------
@Override
public void add() {

    System.out.println("DOA.add");

}

• view

---------------AOPController.java------------------------
@GetMapping("/view.do")
public String view() {

    dao.view();
    System.out.println("Controller.view");

    return "view";
}
-----------------AOPDAO.java-----------------------------
void view();
-----------------AOPDAOImplement.java--------------------
@Override
public void view() {

    System.out.println("DOA.view");

}

 

■ 보조업무 구현 -> Log

• Log.java

//보조업무객체
@Component
@Aspect
public class Log {
	
    //방식 1
    /*
	@After("execution(* add(..))")
	public void m1() {
		
		System.out.println("[보조업무] 기록을 남깁니다..");
		
	}
    */
    
    //방식 2
    @Pointcut("execution(* add(..))")
	public void pc1() {
		//구현부 없음
	}
	
	@After("pc1()")
	public void m1() {
		System.out.println("[보조업무] 기록을 남깁니다..");
	}
	
}
