2. com.w2.file 패키지 생성

3. com.w2.file 패키지에 AwsS3.java 클래스 생성

    - 버킷 이름, 엑세스 키, 시크릿 키 값은 깃허브에 업로드되지 않도록 조심합니다.

4. DB와 연동할 VO를 생성합니다.(고객 이미지)

package com.w2.file;
 
import lombok.Getter;
import lombok.Setter;
import lombok.ToString;
 
@Getter
@Setter
@ToString
public class ClientImageVO {
    private String cmId;    // 이미지 고유 번호
    private String cmName;     // 이미지 이름
    private String cmDir;    // 이미지 저장 경로
    private String cmStatus;    // 이미지 상태(환불, 문의, 리뷰)
}

import java.util.Calendar;
import java.util.Iterator;
 
import org.springframework.beans.factory.annotation.Autowired;

            model.addAttribute("cmvo", cmvo);
        }    
        return "/test/get_image";
    }
}

 

 

6. 서비스를 처리할 FileService.java 인터페이스 생성

package com.w2.file;
 
public interface FileService {
 
    public int insertImage(ClientImageVO cmvo);
}
 

 

7. FileService.java를 상속받는 FileServiceImple.java 클래스 생성

package com.w2.file;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
@Service("fileService")
public class FileServiceImpl implements FileService {
    @Autowired
    private FileDAO filedao;
    
    @Override
    public int insertImage(ClientImageVO cmvo) {
        System.out.println("[ Imple ] : insertImage");
        
        int result = filedao.insertImage(cmvo);
 
        return result;
    }
}
 

 

8. 서비스를 넘겨받아 DB 연동을 처리할 FileDAO.java 클래스 생성

package com.w2.file;
 
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
 
@Repository
public class FileDAO {
 
    @Autowired
    private SqlSessionTemplate sqlSessionTemplate;
    
    public int insertImage(ClientImageVO cmvo) {
        System.out.println("[ FileDAO ] : insertImage");
        
        int result = sqlSessionTemplate.insert("FileVO.insertImage", cmvo);
        
        return result;
    }
}
 

 

9. SQL문을 작성할 file-mapping.xml 파일 생성

<?xml version="1.0" encoding="UTF-8"?>
 
<!-- MyBatis 다운 파일 PDF 에서 붙여넣은 내용입니다. -->
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 
                "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
                
<mapper namespace="FileVO">
    <insert id="insertImage" parameterType="cmvo">
        INSERT INTO client_image VALUES( #{ cmId }, #{ cmName }, #{ cmDir }, #{ cmStatus })
    </insert>
</mapper>

 

10. src/main/resources > mybatis-config.xml 파일에 매핑파일 등록

<?xml version="1.0" encoding="UTF-8"?>
 
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 
                "http://mybatis.org/dtd/mybatis-3-config.dtd">
 
<configuration>
    
    <typeAliases>
        <!-- typeAlias
                - 매핑파일에서 사용하는 type을 지정
                - 애플리케이션에서 SQL 문으로 값을 전달합니다
                - SQL 문 실행 시 반환되는 레코드를 저장하는 용도로 사용하기 위한 빈을 생성합니다.-->
        <typeAlias type="com.w2.file.ClientImageVO" alias="cmvo" />
    </typeAliases>
 
    <!-- SQL 작성문을 지정하여 mapper 파일 경로 알려주는 역할입니다. -->
    <mappers>
        <mapper resource="mappings/file-mapping.xml"/>
    </mappers>
</configuration>

 

11. src/main/resources > applicationContext.xml 파일에 패키지 등록

12. 파일 업로드 페이지 작성

webapp > WEB-INF > views > test > insert_image.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

        <input type="file" name="file2"> 
        <input type="submit" value="insertCmImage.do">
    </form>
</body>
</html>
