이전 수업 개념

 

 

▶ Spring MVC

- Spring DI의 기능과 Spring AOP의 기능이 내장되어있다.

 

▶ Spring MVC 구현 방법

- Java 프로젝트를 Maven 프로젝트로 변경 후 Spring Framework 적용 + 기타 설정

- STS (Spring Tool Suite) → Spring Boot

 

▶ Spring Boot - 유니콘

▶ 전자정부 프레임워크 - Legacy Spring MVC

 

 

아래 흐름에 따라 프로젝트 구성해보기

 

입력 주소 경로 보여지는 페이지
zipcode.daum model2.ZipcodeAction Zipcode.jsp
zipcode_ok.daum model2.ZipcodeOkAction Zipcode_ok.jsp

 

- Maven 리포지토리에서 Mariadb, Lombok 라이브러리 가져오기

 

ZipcodeTO

package model1;

import lombok.Getter;
import lombok.Setter;

@Getter
@Setter
public class ZipcodeTO {
	private String zipcode;
	private String sido;
	private String gugun;
	private String dong;
	private String ri;
	private String bunji;
}

 

ZipcodeOkAction

 

 

게시판 → Spring MVC

 

Model2 (URL → Spring MVC)

board01 프로젝트

 

 

어노테이션

 

 

list1.do → listview1.jsp

list2.do → listview2.jsp

 

▶ 다이나믹 프로젝트 생성 : web04

▶ 메이븐 프로젝트로 변경 : groupId : com.exam / artifactId : web

▶ 패키지 생성 : config

▶ 클래스 생성 : ConfigController1.java

package config;

import org.springframework.web.servlet.ModelAndView;

@Controller
public class ConfigController1 {

	@RequestMapping( "/list1.do" )
	public String handleRequest1() {
		System.out.println( "handleRequest1() 호출" );
		return "listview1";
	}
	
	@RequestMapping( "/list2.do" )
	public String handleRequest2() {
		System.out.println( "handleRequest2() 호출" );
		return "listview2";
	}
    
}

 

 

▶ ConfigController2.java

package config;

import org.springframework.stereotype.Controller;
