STS로는 spring legacy project만들기만 누르면 알아서 만들어주는데 Intellij는 설정해야할게 조금 더 있다.

intellij로 Spring MVC프로젝트를 만들어 보고 폴더구조를 STS에서 만든것과 똑같이 설정해서 구동까지 해볼것이다.

1. 프로젝트 생성

File -> New -> Project를 클릭한다.

Create from archetype을 체크하고 org.apache.maven.archetypes:maven-archetype-webapp을 찾아서 선택한뒤 next를 클릭한다.

Name에 프로젝트 이름 (spring-mvc-project) 을 적고 next를 클릭한다.

프로젝트가 생성된다. 체크한부분에 체크표시가 뜰때까지 꼭 기다린다 시간이 조금 걸린다.

2. 스프링 프레임워크 추가

프로젝트에 우클릭 -> Add Frameword Support를 클릭한다.

왼쪽에서 Spring - Spring MVC를 찾아서 OK를 클릭한다.

3. 폴더구조 설정

윈도우 기준 ctrl + alt + shift + s를 누르면 Project Structure설정에 들어가진다.(왼쪽 상단의 File - Project Structure도 가능) -> 왼쪽에 Moduls탭을 선택 -> src에서 오른쪽클릭 -> new Folder클릭 -> test폴더를 추가한다 -> src - main에서 오른쪽클릭 -> New Folder 클릭 -> java, resources폴더를 추가한다(색깔은 위에 Mark as를 선택하면 된다) -> ok 클릭

4. 기본 패키지, 클래스 생성

src/main/java에서 우클릭 -> new - package -> org.sample.config, org.sample.controller두개의 패키지를 생성한다. -> src/main/java/org.sample.config에 RootConfig, ServletConfig, WebConfig 3개의 클래스를 생성한다.

아래 내용을 붙여넣기한다(기본설정)

• org.sample.config / RootConfig

package org.example.config;

import org.springframework.context.annotation.Configuration;

@Configuration
public class RootConfig {
}

• org.sample.config / ServletConfig

package org.example.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@EnableWebMvc
@ComponentScan(basePackages= {"org.example.controller"})
public class ServletConfig implements WebMvcConfigurer {

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        InternalResourceViewResolver bean = new InternalResourceViewResolver();
        bean.setViewClass(JstlView.class);
        bean.setPrefix("/WEB-INF/views/");
        bean.setSuffix(".jsp");
        registry.viewResolver(bean);
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    }

}

• org.sample.config / WebConfig

package org.example.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class WebConfig extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[]{RootConfig.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[]{ServletConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}

controller 패키지에는 간단히 테스트할 SampleController클래스를 추가한다.

org.sample.controller / SampleController

package org.example.controller;

import lombok.extern.log4j.Log4j;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/sample")
@Log4j
public class SampleController {

    @RequestMapping("")
    public void sample() {
        log.info("sample");
    }

}

아직 의존성 설정을 안해서 빨같 밑줄이 생길텐데 조금있다 설정할것이니 상관없다.

5. Log4j 설정

src/main/resources폴더에서 오른쪽 우클릭 -> new클릭 -> File클릭 -> log4j.xml, log4jdbc.log4j2.properties파일을 추가한다.

안의 내용을 붙여넣기한다.

• /src/main/resources/log4j.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

  <!-- Appenders -->
  <appender name="console" class="org.apache.log4j.ConsoleAppender">
    <param name="Target" value="System.out" />
    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%-5p: %c - %m%n" />
    </layout>
  </appender>

  <!-- Application Loggers -->
  <logger name="org.example" >
    <level value="info" />
  </logger>

  <!-- 3rdparty Loggers -->
  <logger name="org.springframework.core">
    <level value="info" />
  </logger>

  <logger name="org.springframework.beans">
    <level value="info" />
  </logger>

  <logger name="org.springframework.context">
    <level value="info" />
  </logger>

  <logger name="org.springframework.web">
    <level value="info" />
  </logger>

  <!-- Root Logger -->
  <root>
    <priority value="warn" />
    <appender-ref ref="console" />
  </root>

</log4j:configuration>

• /src/main/resources/log4jdbc.log4js.properties

log4jdbc.spylogdelegator.name=net.sf.log4jdbc.log.slf4j.Slf4jSpyLogDelegator

6. xml설정파일 삭제

xml설정이 아닌 java설정을 이용하기 위해 위에 config패키지를 만들었으므로 xml설정 파일 3개는 삭제한다.

7. pom.xml 수정

pom.xml에 모든 내용을 지우고 아래내용을 붙여넣는다.

• pom.xml

pom.xml을 수정한 뒤에는 꼭 프로젝트 루트 디렉터리를 우클릭 한후 Maven - Reload project 꼭 항상 해준다. 이때 아까 생겼던 빨간밑줄이 사라질 것이다.!

8. tomcat 설정하기

우측 상단에 ADD CONFIGURATION 버튼을 클릭한다. -> Add New Configuration - Tomcat Server - local을 클릭한다.

첫화면에서 HTTP port를 8081로 바꾼다.(충돌날 수 도 있기때문에)

다음은 Deployment탭을 클릭해서 +버튼 클릭 -> Artifact클릭

다음은 Application context를 있는 내용을 지우고 /만 입력한다. -> ok클릭

9. 서버 구동 및 테스트

톰캣 설정이 정상적으로 되었다면 우측상단에 아까 눌렀던 ADD CONFIGURATION버튼 옆 run버튼(세모모양)이 불이 들어온다.
클릭해서 구동해보고 주소창에 http://localhost:8081/sample를 입력해본다.

창에는 위와같이 나온다.(해당 jsp파일을 만들지 않았으므로 정상이다)

위에 블록친 로그가 찍히면 성공이다.(아까 SampleController에서 입력한 내용이다)
