我在我的 API Rest JWT 身份驗證中實作了，但我創建的例外不起作用。
這是我所期望的：
"timestamp": "2022-06-02T21:56:28.372 00:00",
"error": "BAD_REQUEST",
"message": "Invalid JWT signature",
這就是我得到的：

"message": "No message available",

這是我的 CustomException 類
public class OnlineStoreAPIException extends RuntimeException{
private HttpStatus status;
private String message;
public OnlineStoreAPIException(HttpStatus status, String message) {
this.status = status;
this.message = message;
}
public OnlineStoreAPIException(String message, HttpStatus status, String message1){
super(message);
this.status = status;
this.message = message1;
}
public HttpStatus getStatus() {
return status;
}
@Override
public String getMessage() {
return message;
}
}
這就是我的 globalExceptionHandler
@ControllerAdvice
public class globalExceptionHandler extends ResponseEntityExceptionHandler {
@ExceptionHandler(OnlineStoreAPIException.class)
public ResponseEntity<ErrorDetails>
handlerOnlineStoreAPIException(OnlineStoreAPIException ex , WebRequest webRequest){
ErrorDetails errorDetails = new ErrorDetails(new Date(), ex.getMessage(),
webRequest.getDescription(false));
return new ResponseEntity<ErrorDetails>(errorDetails, HttpStatus.BAD_REQUEST);
}
最后，這就是我在 JwtTokenProvider 中的方法 validateToken 中所擁有的：
公共布爾驗證令牌（字串令牌）{
try{
Jwts.parser().setSigningKey(jwtSecret).parseClaimsJws(token);
return true;
}catch (SignatureException ex){
throw new OnlineStoreAPIException(HttpStatus.BAD_REQUEST, "Invalid JWT signature");
}
catch (MalformedJwtException ex){
throw new OnlineStoreAPIException(HttpStatus.BAD_REQUEST, "Invalid JWT token");
}
catch (ExpiredJwtException ex){
throw new OnlineStoreAPIException(HttpStatus.BAD_REQUEST, "Expired JWT token");
}
catch (UnsupportedJwtException ex){
throw new OnlineStoreAPIException(HttpStatus.BAD_REQUEST, "Unsupported JWT token");
}
catch (IllegalArgumentException ex){
throw new OnlineStoreAPIException(HttpStatus.BAD_REQUEST, "JWT claims string is empty");
}
}
如果有人能伸出援手，我真的很感激。
uj5u.com熱心網友回復：
這是因為 Spring 過濾器具有不同的錯誤回應機制，與一般例外不同。在我的這個示例中，我使用自定義過濾器來執行 OAuth 作業。
更標準的 Spring 選項是自定義本教程AccessDeniedHandler中討論的。
http.authorizeRequests()
// other configurations
.and().oauth2ResourceServer()
.authenticationEntryPoint(new CustomOAuth2AuthenticationEntryPoint())
.accessDeniedHandler(new CustomOAuth2AccessDeniedHandler();
uj5u.com熱心網友回復：
我通過在 JWTAuthenticationFilter 中添加例外而不是在 JwtTokenProvider 中解決了錯誤：
@Override
protected void doFilterInternal(HttpServletRequest request,
HttpServletResponse response,
FilterChain filterChain) throws ServletException, IOException {
try {
//get JWT from http request
String token = getToken(request);
//validate token
if (StringUtils.hasText(token) && jwtTokenProvider.validateToken(token)) {
//get username from token
String username = jwtTokenProvider.getUsernameByToken(token);
//Load User associated with token
UserDetails userDetails = userDetailsService.loadUserByUsername(username);
UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
authenticationToken.setDetails((new WebAuthenticationDetailsSource().buildDetails(request)));
SecurityContextHolder.getContext().setAuthentication(authenticationToken);
}
filterChain.doFilter(request, response);
}catch (SignatureException ex){
response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
((HttpServletResponse) response).sendError(HttpServletResponse.SC_BAD_REQUEST, "Invalid JWT signature");
}
catch (MalformedJwtException ex){
response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
((HttpServletResponse) response).sendError(HttpServletResponse.SC_BAD_REQUEST, "Invalid JWT token");
}
catch (ExpiredJwtException ex){
response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
((HttpServletResponse) response).sendError(HttpServletResponse.SC_BAD_REQUEST, "Expired JWT token");
}
catch (UnsupportedJwtException ex){
response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
((HttpServletResponse) response).sendError(HttpServletResponse.SC_BAD_REQUEST, "Unsupported JWT token");
}
catch (IllegalArgumentException ex){
response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
((HttpServletResponse) response).sendError(HttpServletResponse.SC_BAD_REQUEST, "JWT claims string is empty");
}
}
