在Spring Security中如何从自定义AuthenticationManager捕获异常?

我使用Crowd的Java集成到Spring Security中,其中涉及将Crowds SimpleAuthenticationManager配置为身份验证提供程序。当用户无法根据无法进行身份验证的原因进行身份验证时,SimpleAuthenticationManager会引发多个异常。我在Spring Security中想知道如何捕获该异常并将JSON响应返回给客户端?

我已经尝试添加AccessDeniedHandler但是这会收到一个新的异常,它没有原始异常作为原因。

在谷歌搜索和搜索StackOverflow时,我错过了这篇文章: Spring security 3 http-basic authentication-success-handler

事实证明,正如其他问题/答案所指出的,您需要扩展BasicAuthenticationFilter并实现onUnsuccessfulAuthentication()方法。然后使用以下命令将其添加到您的安全配置中:

http.addFilter(new CustomBasicAuthenticationFilter(authenticationManagerBean()))

编辑实际上看起来Spring现在还在包装异常,但是你可以得到一些稍微更具体的异常,这很有帮助。

您可以使用ResponseEntityExceptionHandler注释扩展@ControllerAdvice。这将捕获异常,您可以处理和发送自定义响应。例如:

@ControllerAdvice
public class CustomExceptionHandler extends ResponseEntityExceptionHandler {
    private static final Logger log = LoggerFactory.getLogger(CustomExceptionHandler.class);

    public CustomExceptionHandler() {
    }

    // overriding an exception that already is been handled in ResponseEntityExceptionHandler
    @Override
    protected ResponseEntity<Object> handleMissingPathVariable(MissingPathVariableException ex,
            HttpHeaders headers, HttpStatus status, WebRequest request) {
        log.warn(ex.toString());

        final String parameter = ex.getParameter().getParameterName();
        final String detailMessage = ex.getMessage();
        final String message = "Parameter " + parameter + " is missing.";

        final ErrorMessageDTO result = new ErrorMessageDTO(HttpStatus.BAD_REQUEST, message, parameter, detailMessage, null);
        return ResponseEntity.badRequest().body(result);
    }

    // Custom handle to intercept BadCredentialsException
    @ExceptionHandler(BadCredentialsException.class)
    @ResponseBody
    ResponseEntity<Object> handleBadCredentialsException(HttpServletRequest req,
            BadCredentialsException ex) {
        log.warn(ex.toString());

        final ErrorMessageDTO result = new ErrorMessageDTO(HttpStatus.UNAUTHORIZED, ex.getMessage());
        return ResponseEntity.badRequest().body(result);
    }

}
