2. Access helpers via `ComponentUtil.getXyzHelper()`
3. Use `OptionalEntity<T>` for nullable entity returns
4. Use DBFlute behavior classes (Bhv) for data access
5. Put user-facing strings in `fess_label_*.properties`
6. Run `mvn formatter:format` and `mvn license:format` before committing

1. Don't edit files in `bsentity/` or `bsbhv/` (generated code)

# 응답 상태 코드 { #response-status-code }

응답 모델을 지정하는 것과 같은 방법으로, 어떤 *경로 처리*에서든 `status_code` 매개변수를 사용하여 응답에 사용할 HTTP 상태 코드를 선언할 수도 있습니다:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* 등

{* ../../docs_src/response_status_code/tutorial001_py310.py hl[6] *}

/// note | 참고

`status_code` 는 "데코레이터" 메소드(`get`, `post` 등)의 매개변수입니다. 모든 매개변수들과 본문처럼 *경로 처리 함수*가 아닙니다.

///

`status_code` 매개변수는 HTTP 상태 코드를 숫자로 입력받습니다.
