2.파일전송

먼저 파일전송을 위한 cos라이브러리를 다운받아야함.http://mvnrepository.com/artifact/com.servlets/cos/09May2002
maven사이트에서 라이브러리 검색을 하고, pom.xml에 붙어넣을 dependency 가져옴


라이브러리 가져오는 2번째 방법은 이클립스pom.xml dependencies탭에서 cos라이브러리 검색

  System.out.println(arg0.getParameter("data"));
  
  ModelAndView modelAndView = new ModelAndView();

  modelAndView.addObject("data", arg0.getParameter("data"));
  
  return modelAndView;
 }

1. 어노테이션기법으로 context.xml 빈파일을 대체하는 방법

폴더구조


WriteAction.java 
package spring6;

public class WriteAction {
 
 public WriteAction() {
  // 겟빈이 디폴트로 부르는 기본 생성자
  System.out.println("디폴트 생성자 호출");
 }

 public void sayHello(String name){
  System.out.println(name + "님 안녕하세요");
 }

}

Config.java 어노테이션 설정 파일 
package spring6;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class Config {
 @Bean
 public WriteAction action1(){
  return new WriteAction();
 }
}

ApplicationMain.java 
package spring6;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class ApplicationMain {

 public static void main(String[] args) {
  // 어노테이션 기법으로 스프링 빈객체를 만듦
  AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(Config.class);
  
  WriteAction action1 =(WriteAction)ctx.getBean("action1");
  action1.sayHello("홍길동");
 }

}


2. 어노테이션 옵션추가


Config.java 
package spring6;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class Config {
 @Bean
 public WriteAction action1(){
  return new WriteAction();
 }
 
 @Bean(name="action3") //메서드의 이름을 바꿈
 public WriteAction action2(){
  return new WriteAction();
 }
}

ApplicationMain.java 
package spring6;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class ApplicationMain {

 public static void main(String[] args) {
  // 어노테이션 기법으로 스프링 빈객체를 만듦
  AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(Config.class);
  
  WriteAction action1 =(WriteAction)ctx.getBean("action1");
  action1.sayHello("홍길동");
  
  WriteAction action3 =(WriteAction)ctx.getBean("action3"); //바뀐 메서드이름을 써야함 action2 쓰면 에러남
  action3.sayHello("박문수");
 }

}


3. 오버로딩 생성자 사용


WriteAction.java 
package spring6;

public class WriteAction {
 
 public WriteAction() {
