[SpringBoot] 15. 계좌 생성 및 유효성 검사

 

1. 계좌 생성 페이지 만들기(save.jsp)

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

<!-- header.jsp  -->
<%@ include file="/WEB-INF/view/layout/header.jsp"%>

<!-- start of content.jsp(xxx.jsp)   -->
<div class="col-sm-8">
	<h2>계좌 생성(인증)</h2>
	<h5>Bank App에 오신걸 환영합니다</h5>
	<!-- 예외적으로 로그인은 보안 때문에 post로 던지자 -->
	<!-- 
		insert into account_tb(number, password, balance, user_id, created_at)
	 -->
	<form action="/account/save" method="post"> 
		<div class="form-group">
			<label for="number">number:</label>
			<input type="text" class="form-control" placeholder="Enter number" id="number" name="number" value="1002-1234"  >
		</div>
		<div class="form-group">
			<label for="pwd">Password:</label>
			<input type="password" class="form-control" placeholder="Enter password" id="password" name="password" value="1234">
		</div>
		<div class="form-group">
			<label for="balance">balance:</label>
			<input type="number" class="form-control" placeholder="Enter balance" id="balance" name="balance" value="10000"  >
		</div>
		
		<div class="text-right">
			<button type="submit" class="btn btn-primary">계좌 생성</button>
		</div>
	</form>
</div>
<!-- end of col-sm-8  -->
</div>
</div>

<!-- footer.jsp  -->
<%@ include file="/WEB-INF/view/layout/footer.jsp"%>

 

 

2. 계좌 생성 메서드(@PostMapping)만들기

	/**
	 * 계좌 생성 기능 요청
	 * 주소 설계 : http://localhost:8080/account/save
	 * @param dto
	 * @return
	 */
	@PostMapping("/save")
	public String saveProc(SaveDTO dto) {
		// 1. form 데이터 추출(파싱 전략)
		// 2. 인증 검사
		// 3. 유효성 검사
		// 4. 서비스 호출
		User principal = (User) session.getAttribute("principal");
		if(principal==null) {
			throw new UnAuthorizedException(Define.NOT_AN_AUTHENTICATED_USER, HttpStatus.UNAUTHORIZED);
		}
		
		if(dto.getNumber()==null||dto.getNumber().isEmpty()) {
			throw new DataDeliveryException(Define.ENTER_YOUR_ACCOUNT_NUMBER, HttpStatus.BAD_REQUEST);
		}
		if(dto.getPassword()==null||dto.getPassword().isEmpty()) {
			throw new DataDeliveryException(Define.ENTER_YOUR_PASSWORD, HttpStatus.BAD_REQUEST);
		}
		if(dto.getBalance()==null||dto.getBalance()<=0) {
			throw new DataDeliveryException(Define.ENTER_YOUR_BALANCE, HttpStatus.BAD_REQUEST);
		}
		
		accountService.createAccount(dto,principal.getId());
		
		return "redirect:/index";
	}

 

 

3. 계좌 생성 쿼리 보내는 메서드 만들기

	/**
	 * 계좌 생성 기능 
	 * @param dto
	 * @param id
	 */
	// 트랜잭션
	@Transactional
	public void createAccount(SaveDTO dto, Integer principalId) {
		int result=0;
		
		try {
			result=accountRepository.insert(dto.toAccount(principalId));
		} catch (DataAccessException e) {
			throw new DataDeliveryException(Define.INVALID_INPUT, HttpStatus.INTERNAL_SERVER_ERROR);
		} catch (Exception e) {
			throw new DataDeliveryException(Define.UNKNOWN, HttpStatus.SERVICE_UNAVAILABLE);
		}

		if(result==0) {
			throw new DataDeliveryException(Define.FAILED_PROCESSING, HttpStatus.INTERNAL_SERVER_ERROR);
		}
		
	}
