+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
+#
+#       You can find Gradle at https://github.com/gradle/gradle/.

+# EAPIM 에러 응답 포맷 통일 작업 히스토리
+
+## 작업 배경
+
+### 목표
+모든 HTTP 에러 응답을 다음과 같은 표준 JSON 포맷으로 통일:
+```json
+{"error":{"code":"에러코드","message":"에러메시지"}}
+```
+
+## 변경 내역
+
+### 1. MessageUtil 에러 포맷 정의
+**파일**: `elink-online-common/src/main/java/com/eactive/eai/common/util/MessageUtil.java`
+
+- 표준 에러 응답 포맷 정의
+  ```java
+  public static final String ERROR_MESSAGE_DEFAULT_FORMAT = "{\"error\":{\"code\":\"%s\",\"message\":\"%s\"}}";
+  ```
+
+- 에러 코드 상수 추가
+  ```java
+  public static final String ERROR_CODE_AP_ERROR = "E.GW.AP_ERROR";
+  public static final String ERROR_CODE_AUTH_FAIL = "E.GW.AUTH_FAIL";
+  public static final String ERROR_CODE_SERVICE_NOT_FOUND = "E.GW.SERVICE_NOT_FOUND";
+  ```
+
+- 에러 메시지 생성 메서드
+  ```java
+  public static String makeJsonErrorMessage(String code, String msg)
+  public static String makeJsonErrorMessage(String code, String msg, String errorFormat)
+  ```
+
+### 2. 전역 ExceptionHandler 추가
+**파일**: `src/main/java/com/eactive/eai/authserver/config/WebMvcConfig.java` (신규 생성)
+
+Spring MVC 전역 예외 처리를 위한 `@ControllerAdvice` 클래스 추가
+
+**처리하는 예외**:
+- `HttpMessageNotReadableException` - HTTP 메시지 파싱 실패
+- `MethodArgumentNotValidException` - 유효성 검증 실패
+- `MissingServletRequestParameterException` - 필수 파라미터 누락
+- `BindException` - 바인딩 에러
+- `NoHandlerFoundException` - 404 Not Found (핸들러 없음)
+- `AuthenticationException` - 401 Unauthorized (인증 실패)
+- `AccessDeniedException` - 403 Forbidden (권한 없음)
+- `Exception` - 500 Internal Server Error (기타 예외)
+
+**동작 방식**:
+1. 예외 발생 시 적절한 HTTP 상태 코드 설정
+2. request에 `_authServerStatusCode`, `errorMessage` 속성 설정
+3. `/error.jsp`로 forward하여 표준 JSON 응답 생성
+
+### 3. error.jsp 수정
+**파일**: `WebContent/error.jsp`
+
+**변경 사항**:
+- 기존 HTML 에러 페이지를 JSON 응답으로 변경
+- `MessageUtil.makeJsonErrorMessage()` 호출하여 표준 포맷 응답 생성
+- HTTP 상태 코드에 따른 에러 코드 매핑:
+  - 401 → `ERROR_CODE_AUTH_FAIL`
+  - 404 → `ERROR_CODE_SERVICE_NOT_FOUND`
+  - 기타 → `ERROR_CODE_AP_ERROR`
+
+```jsp
+Integer statusCode = (Integer) request.getAttribute("_authServerStatusCode");
+if (statusCode != null) {
+    response.setStatus(statusCode);
+}
+
+String code;
+if (statusCode != null && statusCode == 401) {
+    code = MessageUtil.ERROR_CODE_AUTH_FAIL;
+} else if (statusCode != null && statusCode == 404) {
+    code = MessageUtil.ERROR_CODE_SERVICE_NOT_FOUND;
+} else {
+    code = MessageUtil.ERROR_CODE_AP_ERROR;
+}
+
+String message = (String)request.getAttribute("errorMessage");
+String jsonErrorMessage = MessageUtil.makeJsonErrorMessage(code, message);
+out.println(jsonErrorMessage);
+```
+
+### 4. WebSecurityConfig 에러 처리 추가
+**파일**: `src/main/java/com/eactive/eai/authserver/config/WebSecurityConfig.java`
+
+**변경 사항**:
+- Spring Security 레벨의 인증/권한 에러 처리 추가
+- `authenticationEntryPoint`: 401 Unauthorized → error.jsp 포워딩
+- `accessDeniedHandler`: 403 Forbidden → error.jsp 포워딩
+- `/error.jsp` 접근 허용 설정 추가
+
+### 5. web.xml 설정 추가
+**파일**: `WebContent/WEB-INF/web.xml`
+
+**변경 사항**:
+- DispatcherServlet에 `throwExceptionIfNoHandlerFound=true` 설정 추가
+  ```xml
+  <init-param>
+      <param-name>throwExceptionIfNoHandlerFound</param-name>
+      <param-value>true</param-value>
+  </init-param>
+  ```
+  → 핸들러 없을 시 `NoHandlerFoundException` 발생하도록 설정
+
+- error-page 매핑 (400, 401, 403, 404, 500 등)
+  ```xml
+  <error-page>
+      <error-code>404</error-code>
+      <location>/error.jsp</location>
+  </error-page>
+  ```
+  → Servlet 레벨에서 발생한 에러도 error.jsp로 라우팅
+
+### 6. KjbMGOAuth2Controller 에러 처리 적용
+**파일**: `src/main/java/com/eactive/eai/authserver/custom/KjbMGOAuth2Controller.java`
+
+**변경 사항**:
+- `JwtAuthException`, 일반 예외 처리 시 `MessageUtil.makeJsonErrorMessage()` 사용
+- HTTP 400/401 에러를 표준 포맷으로 반환
+
+### 7. BearerTokenContoller 에러 처리 적용
+**파일**: `src/main/java/com/eactive/eai/authserver/custom/BearerTokenContoller.java`
+
+**변경 사항**:
+- `MessageUtil` import 추가
+- 기존 OAuth2 RFC 6749 에러 포맷을 MessageUtil 표준 포맷으로 변경
+- `JwtAuthException`: HTTP 401 + `ERROR_CODE_AUTH_FAIL`
+- 일반 예외: HTTP 500 + `ERROR_CODE_AP_ERROR`
+
+### 8. BearerTokenFilter 에러 처리 적용
+**파일**: `src/main/java/com/eactive/eai/authserver/custom/BearerTokenFilter.java`
+
+**변경 사항**:
+- `MessageUtil` import 추가
+- 필터에서 발생하는 에러 응답을 MessageUtil 표준 포맷으로 변경
+- `JwtAuthException`: HTTP 401 + `ERROR_CODE_AUTH_FAIL`
+- 일반 예외: HTTP 500 + `ERROR_CODE_AP_ERROR`
+- JSONObject 직접 생성 방식 제거
+
+### 9. ApiAdapterController 에러 처리 적용
+**파일**: `src/main/java/com/eactive/eai/adapter/controller/ApiAdapterController.java`
+
+**변경 사항**:
+- Adapter URI를 찾을 수 없는 경우: `ERROR_CODE_SERVICE_NOT_FOUND`
+- Adapter를 찾을 수 없는 경우: `ERROR_CODE_AP_ERROR`
+
+## 적용 범위
+
+### 처리되는 에러 시나리오
+
+1. **OAuth2 토큰 발급 실패** (`/mapi/oauth2/token`)
+   - 필수 파라미터 누락, 잘못된 grant_type, 인증 실패 등
+   - HTTP 400/401 + 표준 JSON 에러 응답
+
+2. **CA Bearer 토큰 발급 실패** (`/auth/oauth/v2/token`)
+   - 잘못된 grant_type, 존재하지 않는 client_id, 잘못된 client_secret, scope 오류 등
+   - HTTP 401/500 + 표준 JSON 에러 응답
+
+3. **Bearer 토큰 인증 실패** (`/api/auth/*`)
+   - 토큰 만료, 잘못된 토큰 등
+   - HTTP 401 + 표준 JSON 에러 응답
+
+4. **404 Not Found**
+   - 존재하지 않는 API 엔드포인트 호출
+   - HTTP 404 + 표준 JSON 에러 응답
+
+5. **400 Bad Request**
+   - 잘못된 JSON 포맷, 필수 파라미터 누락 등
+   - HTTP 400 + 표준 JSON 에러 응답
+
+6. **403 Forbidden**
+   - 권한 없는 리소스 접근
+   - HTTP 403 + 표준 JSON 에러 응답
+
+7. **500 Internal Server Error**
+   - 서버 내부 오류
+   - HTTP 500 + 표준 JSON 에러 응답
+
+## 테스트
+
+테스트 코드는 별도 모듈(`kjb-errors`)에 작성됨.
+
+**테스트 문서**: `kjb-errors/src/test/java/com/eactive/eai/kjb/errors/EAPIM_ExceptionHandler_Test.md`
+
+**주요 테스트**:
+- `OAuth2TokenSuccessTest` - OAuth2 토큰 발급 성공
+- `OAuth2BearerAuthTest` - Bearer 토큰 인증 성공
+- `OAuth2BearerAuth404ErrorTest` - Bearer 토큰 인증 후 404 에러
+- `ExceptionHandler400ErrorTest` - 400 에러 응답 검증
+- `ExceptionHandler404ErrorTest` - 404 에러 응답 검증
+- `ExceptionHandlerSuccessTest` - 일반 API 정상 응답
+- `BearerTokenSuccessTest` - CA Bearer 토큰 발급 성공
+- `BearerTokenErrorTest` - CA Bearer 토큰 발급 에러 (5가지 케이스)
+- `BearerTokenFilterErrorTest` - Bearer 토큰 필터 인증 실패
+
+**검증 항목**:
+- HTTP 상태 코드 정확성
+- 응답 포맷이 `{"error":{"code":"...","message":"..."}}` 형식인지 확인
+- 에러 코드가 적절히 매핑되는지 확인
+
+## 에러 코드 매핑
+
+| HTTP Status | Error Code | 설명 |
+|-------------|-----------|------|
+| 400 | E.GW.AP_ERROR | Bad Request (잘못된 요청) |
+| 401 | E.GW.AUTH_FAIL | Unauthorized (인증 실패) |
+| 403 | E.GW.AP_ERROR | Forbidden (권한 없음) |
+| 404 | E.GW.SERVICE_NOT_FOUND | Not Found (서비스 없음) |
+| 500 | E.GW.AP_ERROR | Internal Server Error (서버 오류) |
+
+## 참고 사항
+
+### 주의사항
+- `MessageUtil.makeJsonErrorMessage()`는 메시지 내의 특수문자를 JSON escape 처리함
+- error.jsp는 JSON 응답만 출력하므로 브라우저에서 HTML로 보이지 않음
+- 상태 코드는 실제 HTTP 응답 상태 코드와 일치해야 함
