BoardVO.java 

package sp.mvc.board.vo;   public class BoardVO {  private int boardSeq;  private String boardType;  private int step;  private int depth;  private String title;  private String content;  private String ip;  private String deleteYn;  private String regiDt;  private String regiUser;  private String modiDt;  private String modiUser;    public int getBoardSeq() {   return boardSeq;  }  public void setBoardSeq(int boardSeq) {   this.boardSeq = boardSeq;  }          ......  @Override  public String toString() {   return "BoardVO [boardSeq=" + boardSeq + ", boardType=" + boardType     + ", step=" + step + ", depth=" + depth + ", title=" + title     + ", content=" + content + ", ip=" + ip + ", deleteYn="     + deleteYn + ", regiDt=" + regiDt + ", regiUser=" + regiUser     + ", modiDt=" + modiDt + ", modiUser=" + modiUser + "]";  } }

 

BoardDaoImpl.java

package sp.mvc.board.dao; import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport; import sp.mvc.board.vo.BoardVO;   public class BoardDaoImpl extends SqlMapClientDaoSupport implements BoardDao {    @Override  public BoardVO getBoardDetail(int boardSeq) {   // TODO Auto-generated method stub   BoardVO boardDetail = (BoardVO)getSqlMapClientTemplate().queryForObject("board.selectBoardDetail", boardSeq);      return boardDetail;  }    @Override  public Object insertBoardItem(BoardVO boardVo) {   // TODO Auto-generated method stub   return getSqlMapClientTemplate().insert("board.insertBoard", boardVo);  } }

 

BoardServiceImpl.java

package sp.mvc.board.service; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import sp.mvc.board.dao.BoardDao; import sp.mvc.board.vo.BoardVO;   @Component public class BoardServiceImpl implements BoardService {    @Autowired  private BoardDao boardDao;    @Override  public BoardVO getBoardDetail(int boardSeq) {   // TODO Auto-generated method stub   return boardDao.getBoardDetail(boardSeq);  }    @Override  public Object insertBoardItem(BoardVO boardVo) {   // TODO Auto-generated method stub   return boardDao.insertBoardItem(boardVo);  } }

 

BoardController.java

package sp.mvc.board.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.servlet.ModelAndView; import sp.mvc.board.service.BoardService; import sp.mvc.board.vo.BoardVO;   @Controller public class BoardController {    @Autowired  private BoardService boardService;    @RequestMapping("/boardDetail.sp")   public ModelAndView getDetail(@RequestParam(value="seq", required=false, defaultValue="1") int boardSeq){   System.out.println("boardSeq : " + boardSeq);   BoardVO boardDetail = boardService.getBoardDetail(boardSeq);      System.out.println("boardDetail : " + boardDetail.toString());      ModelAndView modelAndView = new ModelAndView("board/boardDetail");   modelAndView.addObject("boardDetail", boardDetail);   return modelAndView;  }     @RequestMapping("/boardInsert.sp")  public void insertItem(){      BoardVO boardVo1 = new BoardVO();   boardVo1.setBoardSeq(1);          //무결성 Exception   boardVo1.setBoardType("001");   boardVo1.setStep(1);   boardVo1.setTitle("spring 3.0 mvc - 1");   boardVo1.setContent("컨텐츠 내용 입력... 테스트 중...");   boardVo1.setIp("123.123.321.321");        BoardVO boardVo2 = new BoardVO();   boardVo2.setBoardSeq(2148);   boardVo2.setBoardType("001");   boardVo2.setStep(1);   boardVo2.setTitle("spring 3.0 mvc - 1");   boardVo2.setContent("컨텐츠 내용 입력... 테스트 중...");   boardVo2.setIp("123.123.321.321");        System.out.println("===== 1 =====");   boardService.insertBoardItem(boardVo2);   System.out.println("===== 2 =====");   boardService.insertBoardItem(boardVo1);   //무결성 제약 조건 Exception 발생   System.out.println("===== 3 =====")  } }

● boardVo2 : 정상적으로 insert가 되는 param값을 가지고 있음

  boardVo1 : boaerSeq가 무결성 제약 조건에 위배되는 값을 가지고 있음

 

◆ 트랜잭션이 설정되어 있지 않다면 위의 경우 boardVo2는 정상적으로 insert가 되고(commit) boardVo1의 경우 Exception 발생 ==>> 하지만 트랜잭션을 설정함으로써 정상적으로 데이터가 들어가는 boardVo2의 경우도 boardVo1의 Exception으로 인해 rollback이 됨

 

 

LogAspect.java

package sp.mvc.aop; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.annotation.AfterThrowing; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Before; import org.aspectj.lang.annotation.Pointcut;   @Aspect public class LogAspect {    @Pointcut(value="execution(* sp.mvc.board.controller.*.*(..))")  public void logPrint(){};      @AfterThrowing(pointcut="logPrint()", throwing="ex")  public void afterThrowing(JoinPoint joinPoint, Exception ex){   System.out.println("***** afterThrowing *****");   System.out.println("method : " + joinPoint.toShortString());   System.out.println("Exception : " + ex.toString());  } }

● pointcut 즉, sp.mvc.board.controller.*.*(..)의 표현식에 해당되는 곳에 "txAdvice"가 적용 되고,

"txAdvice"의 method name은 "insertItem" 이므로

실제 적용되는 표현식은 sp.mvc.board.controller.*.insertItem(..) 이렇게 됨
