인텔리제이에서 스프링 MVC + MariaDB 세팅하기 maven (spring on intellij)

 

 

환경

운영체제 : Windows 10

JDK : 9.0.4

IDE : Intellij IDEA ULTIMATE

프레임워크 : Spring MVC(4.3.18.RELEASE) + MAVEN(5.2.3.RELEASE)

서버 : Tomcat (7.0.105)

DB : MariaDB

 

 

 

1. MAVEN 프로젝트 생성

Intellij에서 Maven 프로젝트를 생성해 줍니다. (체크 : Maven, Project SDK = JDK9)

 

 

 

 

GroupId와 ArtifactId를 입력해줍니다. GroupId는 프로젝트를 그루핑해주는 ID이고 ArtifactId는 GroupId와 Version을 생략한 이 프로젝트의 이름이라고 보면 됩니다.(ArtifactId로 폴더이름 생성됨)

 

Next와 Finish를 눌러줍니다.

 

 

 

 

프로젝트가 만들어지면 오른쪽 아래에 "Enable Auto-Import"를 클릭합니다.

 

 

 

 

프로젝트 이름에서 오른쪽 마우스 -> "Add Framework Support..."를 클릭해줍니다.

 

 

 

왼쪽에서 Spring안에 "Spring MVC (5.2.3.RELEASE) 를 체크 해주고 OK를 눌러줍니다. (버전은 다를 수 있음)

그러면 프로젝트에 "web"폴더가 생기며 안에 servlet.xml등이 생깁니다.

 

 

 

 

2. RUN (Tomcat Server) 설정

우측 상단의 "ADD CONFIGURATION..."을 클릭하면 아래의 "Run/Debug Configurations"창이 뜹니다.

이후 왼쪽의 옥색 "+"를 클릭 -> "Tomcat Server"를 클릭 -> "Local"을 클릭합니다. (Tomcat이 Local에 있는경우)

 

 

 

 

오른쪽 아래의 "FIX"버튼을 눌러줍니다.

 

 

 

"Application context"가 "/backendspring_war_exploded"로  되어있는데 이거를 "/"로 replace해줍니다.

그리고 "OK"눌러줍니다.

 

 

 

 

2. Dependency 추가 (POM.xml)

 

아래의 dependency를 pom.xml의 <project> </project안에 </version>아래에 붙여넣어줍니다.

@Repository
public class StocksRepository {
 
    private SqlSession sqlSession;

    public StocksRepository(SqlSession sqlSession){
        this.sqlSession = sqlSession;
    }
 
    public Stocks findStocksByCompany(String company){
        return sqlSession.selectOne("database.getStocksByCompany",company);
    }
}

d. mybatis의 query문 추가(resource/database/query.xml)

(연결할 db에따라 필드명 db명 다름)

 

 

 

 

5. Controller 설정 (src/main/java/groupId/controller1 and 2)

groupid이름으로 패키지 생성

src/main/java 아래에 프로젝트 생성 시 입력했던 groupId로 패키지를 만들어줍니다.

 

만든 패키지 안에 controller1와 controller2패키지 2개를 만듭니다.

 

 

 

a. HomeController.java
