PROGRAMING: 04day Spring

1.어노테이션으로 aspectj라이브러리를 이용해서 aop를 만들기
폴더구성

pom.xml 에서 라이브러리 추가

<dependency>

            <artifactId>aspectjweaver</artifactId>
            <version>1.6.8</version>
        </dependency>

Action.java

package spring;

public interface Action {
 public abstract void sayHello1();
 public abstract void sayHello2();
}

WriteAction.java

package spring;

public class WriteAction implements Action {
 private String name;
 
 public void setName(String name){
  this.name = name;
 }
 
 @Override
 public void sayHello1() {
  // TODO Auto-generated method stub
  System.out.println("sayHello1 시작");
  System.out.println("Hello1 " + name);
  System.out.println("sayHello1 끝");
 }
 
 @Override
 public void sayHello2() {
  // TODO Auto-generated method stub
  System.out.println("sayHello2 시작");
  System.out.println("Hello2 " + name);
  System.out.println("sayHello2 끝");
 }

}

LoginAdvice.java

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;

//xml에서 기술 했던부분을 java클래스에서 기술함
@Aspect
public class LoginAdvice {

5. 모델만들기

폴더구성

listAction1.java 만들때 Controller 상속받아야 함

package spring;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

import com.sun.swing.internal.plaf.metal.resources.metal;

public class listAction1 implements Controller {

 @Override
 public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
  // TODO Auto-generated method stub
  
  System.out.println("ListAction1 : handleRequest() 호출");
  ModelAndView modelAndView = new ModelAndView();
  modelAndView.setViewName("listView1");
  
  //return new ModelAndView("listView1");
  return modelAndView;
 }

}

listAction2.java

package spring;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class listAction2 implements Controller {

 @Override
 public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
  // TODO Auto-generated method stub
  
  System.out.println("ListAction2 : handleRequest() 호출");
  return new ModelAndView("redirect:/index.jsp"); //바로 보냄
 }

}

webContext3.xml
