srping mvc를 위한 환경설정

다형성

srping의 3요소

di   장기 클래스에 인공지능을 넣는 것을 주입 장기 클래스에 인공지능을 넣지 않으면 실행 안됨 의존적이다. 

의존 d 주입 i

ioc     제어의 역전 나는 틀만 만들어 주고 사용자가 제어하는 것 ex) 울어라 했을때 내가 울리는게 아니라 사용자가 울리는 것임.

   ex)  웹에 대한 컨트롤을 사용자가 한다. 장기 바둑중에 고르라고했는데 고           르는것은 상대방이 함

   ex)  tomcat도 제어의 역전에 해당함.

mvc파일을 분리시켜서 작업하자

1. spring mvc 환경 구축하기

maven 선택 -> create check해제 -> spring01 x2 finish -> spring 속성 -> project facets -> dynamic web module와 java의 버전 확인

2. java버전및 web 버전 설정

java프로젝트 폴더 위치 속성창 resource에서 주소확인 .settings -> C:\Users\user\eclipse-workspace\spring01\.settings

-> org.eclipse.jdt.core.prefs라는 파일을 메모장으로 연다 -> 1.5를 1.8로 바꾼후 저장

-> org.eclipse.wst.common.project.facet.core 1.5를 1.8 2.3을 3.0으로 바꾼후 저장

-> 

프로젝트 클릭후 alt f5 포스 체크 후 확인 -> 버전확인 -> runtime apply ->apply close

3. xml 들어가서 복붙 url밑으로 지우고 /build까지

<properties>
<spring.version>4.0.1.RELEASE</spring.version>

</build>
 

넣기

4. 프로젝트 src -> main -> webapp -> web-inf -> web.xml 더블클릭 밑에 source탭 열기 후 싹다 지우기

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app> 

넣기

5 프로젝트 src -> main -> webapp -> web-inf에서 new 이름 xml밑에 XML file next 파일명 dispatcher-servlet 입력 finish

xml 들어가서 source 지우고 

<?xml version="1.0" encoding="UTF-8"?>
 
<beans xmlns ="http://www.springframework.org/schema/beans"
xmlns:context ="http://www.springframework.org/schema/context"

http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
 
<context:component-scan base-package="Pack01" />
 
<mvc:annotation-driven/>
<mvc:default-servlet-handler/>
 
<mvc:view-resolvers>
<mvc:jsp prefix="/WEB-INF/Views/"/>
</mvc:view-resolvers>
 
</beans>
 

넣고 alt f5 오류안없어질 경우 포스 다 체크해주기

6 index 에 넣고 실행

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ page import="java.util.*, java.text.*"%>
 
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
 
<head>
<title>메인 페이지</title>
</head>
<body>
<%=new Date()%>
<h2>Hello World</h2>
 
</body>
 

7 src -> main 에서 new 폴더 ->폴더안에서 new java밑에 class next package이름 Pack01 name은 Tiger static void check안함 finish

Tiger 위에 @con ctrl space -> controller

import org.springframework.stereotype.Controller;
 
@Controller

springframework

이게 spring쓰고있따는거임

@req ctrl space @RequestMapping

package Pack01;
 
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
 
@Controller
public class Tiger {
    @RequestMapping("t1")
    String fnuc() {
        System.out.println("들어왔음");
        return null;
    }
}
 

이런형태

spring만약 안될경우에는

C:\Users\user\.m2\repository 

에있는 파일들을 날려버리고 다시 atl f5하자

두번째

pom.xml 맨 밑부분 source 자바 버전을 맞춰줘야된다. 위에 artifactId안에 이름이 같아야된다. spring1

이 maven 소스들 들고오는 근본 주소 http://repo.maven.apache.org/maven2/ 

예시 http://repo.maven.apache.org/maven2/javax/servlet/jsp/javax.servlet.jsp-api/2.2.1/

     <dependency>

<groupId>javax.servlet.jsp</groupId>

<artifactId>jsp-api</artifactId>

 위에는 그냥 필요한것
<servlet>자바 없었을때 html직접만듬
<servlet-name>dispatcher</servlet-name> 이 이름을 바꾸게된다 web-inf에 있는 dispatcher xml명을 바꾸어줘야된다.
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>

<context:component-scan base-package="Pack01" />
 패키지 이름을 바꾸면 이것까지 바꿔줘야됨.자바파일 찾을때 pack01에서 찾아라(대소문자구분 확실하게)
<mvc:annotation-driven/>
<mvc:default-servlet-handler/>
 
<mvc:view-resolvers>
<mvc:jsp prefix="/WEB-INF/Views/"/>
jsp파일을 여기서 찾아라 경로지정하는 것임.
