고객의 요그를 반영하는 계층으로 프레젠테이션 계층과 영속 계층의 중간 다리 역할을 한다.
영속 계층은 데이스 베이스를 기준으로 설계 구현
비지니스 계층은 로직을 기준으로 해서 처리하게 된다,
일반적으로 비지니스 영역에 있는 객체들은 서비스라는 용어를 많이 사용한다.
1. 아래처럼 BoardService / BoardServiceImpl (인터페이스) 생성
1. BoardService
package org.zerock.service;
import java.util.List;
import org.zerock.domain.BoardVO;
public interface BoardService {
public void register(BoardVO board);
public BoardVO get(Long bno);
public boolean modify(BoardVO board);
public boolean remove(Long bno);
public List<BoardVO> getList();
}
2. BoardServiceImpl
package org.zerock.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.zerock.domain.BoardVO;
import org.zerock.mapper.BoardMapper;
import lombok.AllArgsConstructor;
import lombok.Setter;
@Service
@AllArgsConstructor
public class BoardServiceImpl implements BoardService {
@Setter(onMethod_ = @Autowired )
private BoardMapper mapper;
@Override
public void register(BoardVO board) {
// TODO Auto-generated method stub
}
@Override
public BoardVO get(Long bno) {
// TODO Auto-generated method stub
return null;
}
@Override
public boolean modify(BoardVO board) {
// TODO Auto-generated method stub
return false;
}
@Override
public boolean remove(Long bno) {
// TODO Auto-generated method stub
return false;
}
@Override
public List<BoardVO> getList() {
// TODO Auto-generated method stub
return null;
}
}
3.root-context.xml
<context:component-scan base-package="org.zerock.service"></context:component-scan>
4. org.zerock.service.BoardServiceTests
package org.zerock.service;
import static org.junit.Assert.*;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import lombok.Setter;
import lombok.extern.log4j.Log4j;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("file:src/main/webapp/WEB-INF/spring/root-context.xml")
@Log4j
public class BoardServiceTests {
@Setter(onMethod_ = @Autowired )
private BoardService service;
@Test
public void testExist() {
log.info(service);
assertNotNull(service);
}
}
5. 결과 확인
